The Secret of the Ellis Shore ... is the Ellis Clamp, which is designed to be used hundreds of times, making its cost per use "pennies". It is simply designed of a solid rec­tangular collar with two heavy duty malleable castings, which are scorated on the flat surface for firm gripping. Abuse will not break or distort it. The Ellis Clamp is made in four sizes - speci­fications are given below.
How to Use Ellis Clamps:
It takes two Ellis Clamps to make a shore. You will note that one plate on each clamp has 4 nail holes for attaching to the lower shore member. The bottom clamp is slipped on the Ellis Stick first and nailed on with threaded nails 14" from the top. The top clamp is then nailed on 2" from the top of the lower shore member, making the clamps 12" apart, c to c. The use of threaded nails in assembling the lower shore m~mbers permanently attaches the clamps to the wood member, making a standard piece of equipment which can be used over and over again many times on job after job.

MATERIAL: 1/2" round rod and malleable castings for standard sizes. 1/4"x1" flat bar and malleable castings for special sizes.
SIZE: Designed to be used with standard dressed lumber In four sizes: 2x4, 3x4, 4x4, 4x6.

WEIGHT:
2x4, 2-1/2 lbs. 4x4, 3 lbs.
3x4, 2-1/2 lbs. 4x6, 4-1/2 lbs.
CASTINGS: Pivotal, non-slip.
Provides scorated bearing surface against wood.

An Ellis Stick is a selected dressed 4 x 4, cut to standard length (we recommend 7'-0"), with ends squared and stained. By observing the following in making and using Ellis Sticks, additional savings will be effected: Use only good, dry, straight, dressed lumber, preferably No. 1 grade Douglas Fir or Yellow Pine, old growth, free of heart center. Use standard dressed 4 x 4's which measure approximately 3%" X 3Y2:" in cross section. All Ell is Metal Parts are designed to be used with standard dressed 4 x 4's. Cut your 4 x 4's to exact lengths, square the ends and stain. By keeping Ellis sticks exact lengths, carpenters can use them for measuring-squaring the ends makes splicing for high shores easy and stronger with less scabbing and nailing and-staining protects the wood from weather, gives your job a more workmanlike appearance and identifies your property. Experience has proved the 7'-0" length is best as it is just the right height for most uses and is easily worked from ground level.

ELLIS STICKS may be used with Ellis Metal Parts to form all basic assemblies for concrete forming. As the drawings show, the standard lengths are perfectly sized for easy handling.

Ellis Sticks without cutting or heavy nailing may be used over and over on many construction jobs for shores, joists, joist bearers, whalers, wall studs, tower, scaffolding, mudsills for storing materials and other uses. Since Ellis Sticks are lapped instead of being cut and spliced, when used for joists, joist bearers, shores, etc. and since they do not turn and therefore do not have to be heavily nailed and braced, they give 40 to 50 times as many uses as ordinary forming lumber. To use these sticks for adjustable shores, requires two Ellis Clamps. The use of Ellis Metal Parts affords large savings in both labor and material because the shores go up 5 times as fast as when using the measuring, cutting, splicing and wedging of 4x4's method.

SPECIFICATIONS:
MATERIAL: No.1 Douglas Fir or Yellow Pine - old growth, free of heart center.
SIZE: Dressed 4x4's, approximately 3%"x 3'/2 ".
SURFACE: Stained with shingle stain.
ENDS: Squared.
HANDLING: Never too hot or too cold for workmen to handle, regardless of the weather.

“UP AND DOWN" FAST!
You can erect 5 or more Ellis Shores while you are measuring, cutting, splicing, erecting and wedging one 4 x 4 shore.

SPECIFICATIONS:
MATERIALS: Lower Shore Members are composed of two Ellis Clamps with pivotal plates, permanently attached with threaded nails near the top, 12" apart, c to c.; upper shore member of sufficient length to obtain desired height; both lower and upper members of No. 1 Douglas Fir or Yellow Pine, free of heart center, stained and ends squared.
LENGTH: For jobs requiring shores 20' or less the lower shore member should be 7' and the upper shore member long enough to reach desired height. For shores over 20', we suggest putting the upper (or longer) member at the bottom and the lower shore member (with two clamps attached) at the top. By doing this, the bottom member can be braced at recommended intervals and adjustments can be made to the top member by workmen working off scaffold planks laid across the bracing. This eliminates removing several rows of bracing to make minor adjustments.

How to Use Ellis Shores:
First, get the proper length lumber to make an Ellis Shore of the desired height - that being a 7' lower shore member and an Ellis Stick of the proper length. The sketches below give some suggestions for best results in the operation of Ellis Shores. The picture at the left shows a man raising the upper shore member to the approximate shore height, final adjustment is made with the Ellis Jack. When the desired height is obtained, the clamps should be tapped down (a hammer lug is provided on the clamp plate) to seat them and a safety nail is driven in the shore above each plate. This nail does not support any load, but simply keeps the clamps from vibrating loose.

Allowable maximum value of 6,000 Ibs. per shore is based
upon a safety factor of 3, against failure of the mechanical mechanism of splice joint.
ALLOWABLE LOAD: Table based upon allowable unit stresses of 1,500 Ibs. per sq. in. for wood members of fir or yellow pine, free of knots. This table is based upon approved engineering standards, but does not compensate for unusual conditions.

Tests were made with ELLIS Clamps on No.1 Douglas Fir ELLIS Sticks; Clamps were driven down with a carpenter's hammer before the load came on.
The ELLIS Jack, as is, will lift 1400 lbs. With a 3' piece of pipe slipped on the handle, the Jack will lift 3000 lbs.

To establish the fact that Ellis Shores would withstand loads rec­ommended on forming jobs, Ellis Manufacturing Co. had a series of load tests run under extreme overload conditions. Using the same kind of select 4 x 4's Ellis recommends to contractors and Ellis Clamps, an 11 '-0" Ellis Shore was erected. Increasing amounts of pressure were applied until the load was more than 20,000 Ibs.­but still the Ellis Shore did not break! There was very slight deflection at 6,000 Ibs., and progressive deflection up to 20,000 Ibs. (See test results, table above.) These tests proved once again what contractors already know .. ELLIS SHORES ARE EXTRA SAFE!

SAFETY! Ellis methods assure a 3: 1 safety factor. Shores are double-strong in the middle to prevent buckling; for adequate bracing, nail at any point.
ECONOMY! low initial cost, hundreds of re­uses, great time savings, less waste . . . combine in Ellis Methods for new economy in concrete forming. Save up to 50%!
ADAPTABILITY! Use the same Ellis Equipment on different types of jobs in quick succession . . . suspended floor slabs, columns, beams, overpasses, dams, culverts, ramps, bridges, etc.
SPEED! Ellis "Up & Down" Faster Method is a job-proven speed advantage. Fewer skilled men required ... most shores are slip-ins ­a big timesaver!

The Ellis Jack makes leveling of shores and purlins simple. The Jack grips the wood of the lower shore member and the upper shore member is raised about one inch per stroke through the lifting pressure of the cam at the anchored end of the Jack handle.

SPECIFICATIONS
Handle Length: 12"
Weight: 17 lbs.
Frame Opening: 3-3/4"

This simple Ellis Jack, when used with Ellis Adjustable Shores, will level shores without the time-and-money consuming measuring, cutting, splicing, blocking, or wedging necessary with other methods. The Ellis Jack is a real money saver!

How to Use the Ellis Hand Jack with "Ellis Methods" The Ellis Jack is used in conjunction with Ellis Methods to level forms used in concrete construction. Only a few Ellis Jacks are needed around the job-one for each 100 or even 200 shores. One workman, using the Ellis Jack, can level shores by himself. He simply holds the Jack by the handle with one hand, slips it onto the lower shore member just below the bottom of the upper member, (left) using his other hand to guide the back plate into position. Then he jacks the handle one stroke, which raises the upper member and the form it is supporting about 1-inch. He jars the back plate loose and slips it up into position for the next stroke. Time required for each stroke is about 5·seconds. A story pole and level line may be used for measuring story height to which form must be adjusted (right). NOTE: The Ellis Jack is not used for lowering forms. This is done by simply tapping Shore clamps one at a time with hammer. Nor is the hand Jack used for lifting loads of over 1,400 Ibs. (such as forms and concrete which require correction). Use Ellis Hydraulic Jack.

9 Out of 10 Shores Simply "Slip In" !
Eliminating the need for old-fashioned shore-making, which entailed measuring, cutting, nailing, wedging, etc., the Ellis Slip-In Shore Holder saves a tremendous amount of lumber, time and labor. Just attach "SH's" at desired distance apart along the purlin, with duplex nails, and they are ready to receive adjustable Ellis Shores. After the assembly of end shores and purlin are raised and braced, it's easy to "slip in" the in-between shores ... only a few seconds are required. Instead of three men to erect a shore, just one man is needed!

SPECIFICATIONS
CUP TYPE: 3/16" steel

Here is the new simplified way to do two jobs at once in shoring: Nailed to adjoining ends of two purlins, it is a splicer ... with a shore slipped into the bottom part, it is a shore holder! Thus L-shaped assemblies of purl ins and shores can be extended to any desired length, and a shore supports at the exact center of each joint.

T-Head
Less Nailing! Safeguard Against Racking!
Think of the money you can save by switching to Ellis T-Heads and using Ellis Methods on purlin assemblies, beam forms, etc.! If you have been using conventional heads, you can eliminate-per average head-driving about 25 nails, making 6 saw cuts, and ruining 6 or 7 lineal feet of 1 x 4 or 1 x 6. And you can get hundreds of re-uses! The Ellis T-Head makes this economy possible. Attached to the top of an upper shore member the new T-Head is used either (1) under purlins, or (2) joined to a 3' or 4' 4 x 4 at the center to make a tee-shore.

MATERIAL: 11 Gauge, 4" square tubing welded to 3/16” flat stock (formed).
SIZE: 4" x 4" x 5" tubing; channel 12" long to fit 4 x 4 or 4 x 6.
WEIGHT: 7-1/2 lbs.
DESCRIPTION: This product is made to fit 4 x 4 Ellis Shores only. 4x4's or 4x6's can be used for T member.

Here's the fast, easy and accurate way to form columns with the ELLIS Column Clamps. All parts are connected to make single units with no loose parts to get lost.
The units are identical, no right or left, up or down. Only a hammer is needed to put up the form. Steel bars hold the plywood form sides snugly in place, a wedge is dropped into a rectangular-cut slot and tightened with a tap of a hammer. You can reuse many times.

Many contractors like to use the Ellis Screw Jack for shoring at near-uniform story heights. When shoring a multi-story building and shores are same height, the Ellis Screw Jack is the ticket. Figure your shore height and use a 4X4 13" less to allow for jack. You will then have a 6" adjustment, 3" up or 3" down. A 4X4 of the proper length fits into the top opening to make an adjustable, reusable shore. These can be quickly erected or taken down and are easily adjusted, having adjusting handles which turn machined Acme threads for adjustments up to 6". Screw Jacks are ideal for many gang-shoring situations and for use with horizontal shores. As in the case of all Ellis Methods, this system prevents waste of your forming lumber, assures countless re-uses, and enables you to get the most out of every 4X4.
6X6 Screws Jacks are great for reshoring when used with an Ellis Reshore Spring. Heavier slab loads can be reshored safely. Either use double headed threaded nails or lag screws for secure attachment to lumber.

The Ellis Bridge Jack is a very rugged and durable piece of equipment. The top and bottom plates are 1/2"x9"x9". The Acme screw is 2-1/2" in diameter and is greased for easy turning. 1" diameter round steel rod can be used for extra leverage when turning the screw.
The top plate swivels freely so turning the screw is very easy. Gussets on the top and bottom plate give the Ellis Bridge Jack added support. All welds are full length and very strong. Contractors can use them directly under concrete slabs or beams in tight spots. Also used with timbers for shoring.
The ELLIS BRIDGE JACK is just the thing for supporting loads up to 80,000 lbs.

Clamps onto the slab every 6 feet. Use 2x4's, 2x6's or cable for rails.
ELLIS MANUFACTURING'S GUARD RAIL STANCHIONS are Fast, Safe, Strong and an Affordable way to build your guard rails.

The Ellis Re-Shore Spring is used to keep the Ellis shore tight against the slab during re-shoring concrete slabs. Nail a re-shore spring to the top of each Ellis Shore. Jack the Ellis shore up tight against the slab with the Ellis Jack. No more wasted lumber or labor used in cutting and nailing to the top and bottom of each shore. Just one nail hole is enough to nail the re-shore spring to the top of each Ellis shore. The re-shore spring returns to its original shape for many re-uses. 200 lbs. will compress the re­shore spring flat. It only weighs 3 oz.
