sPnoIFIcA'rroN forming part of Lettersratent No. 746,793, dated 'Beamter 15, 190e. Application iiled October 1903. Serial No. 175'762. (No model.)

To @ZZ whom it may concern/f o Be it known that I, JOHN PREssLEY COLE- MAN, a citizen of the United States, residing at Edgewood, in the county of Allegheny and 5 State of Pennsylvania, have invented certain new and useful Improvements in Wheel and Lever Stands, of which the following is aspecification.

My invention relates to stands which are.

ro employed for supporting o r carrying wheels and levers employed in connection with switch and signal operating connections.

I will describe a stand embodying my in vention and then point out the novel features I5 thereof in claims.

In the accompanying drawings, Figure 1 is a view in elevation of a wheel-stand embodying my invention. Fig. 2 is a detail View, partlyin elevation and partly in vertical seczo tion, of a portion of the wheelstand shown in Fig. l. Fig. 3 is a detail view, partly in elevation and partly in Vertical section, showinga modication of my invention. Fig. 4 is a top plan of Fig. l, but showing levers mounted in the stands.

Similar letters of reference designate corresponding parts iu all ofthe gures.

The stand comprises end supports and bars intermediate the end supports, between which 3o wheels or sheaves or levers are mounted. Each end support is made up of a number of sections or parts and comprises a base-piece a, a bolt a', and llers a2, which serve to space the bars. The base-piece a is adapted to be secured to a tie or other support, and it is provided with a recess to receive the head of the bolts a. Preferably the recess will be angular to prevent the head of the bolt from turning; but separate means .may 4o be provided for this purpose. Each filler is preferably in the form of a collar, washer,or nipple, and means are provided for centering and retaining it ycentered about the bolt a'. As shown in Fig. 2, these means consist of an interior annular rib or projection a4, secured to or integral with the filler, or, as shown in Fig. 3, the means consists of a groove a5, provided in one or both surfaces of a bar to receive the edge or edges of adjacent collars.

Instead of the annular rib one or more radial projections may be employed.

v B B', duc., designate bars which extend between two end supports. o At least two bars are required for each sta-nd. Additional bars are employed according to the number of superimposed wheels or levers required. The bars B B', dac., may be of any desired length between the end supports.

W designates the wheels or sheaves. The sheaves may be fast on shafts w,or they may be loosely mounted on the shafts. More than one sheave may be arranged on a single shaft if the sheaves are arranged directly above one another. If the sheaves are staggered in the stand, a shaft may be provided vfor each sheave. The shafts.w are suitably journaled in the bars. t in openings provided for them in the bars. Cotter-pins w2 or other means may be provided for retaining the shafts in their journals. v

Instead of sheaves being mounted in the stand levers L, of any, type may be suitably mounted-in the stand. (See Fig. Ll.) In this figure I have shown a lever of the bell-crank type, suitably fulcrumed at itsangle.v

In assembling a stand the bolts of the end support-s arepassed through the base-pieces a, and then a bar and fillers are alternately placed on the bolts until the desired height of stand is obtained. A nut t6 is then put on each bolt andV the parts firmly clamped together by turning the nut on the bolt. Instead separate clamping means may be employed.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. A stand for signal and switch operating connections comprising end support-s made in separable parts and detachable bars.

2. In a stand for signal and switch operating connections, the combination of detachable bars, and end supports, each of Ywhich comprises a base-piece, one or more fillers and means for clamping together the base-piece, fillers and bars.

3. In a stand for signal and switch operating connections, the combination of detach- (inV As here shown, they A able bars, and end supports, each of which comprises a base-piece, one or more fillers and a bolt, the bolt being adapted to clamp t0- gether the base-piece, fillers and bars.

4. In a stand for signal and switch operating connections, the combination of detachable bars, and end supports, each ofrwhich comprises a base-piece, one or more fillers, means for clamping together the base-piece, filler and bars, and means for centering the filler or fillers.

5. An end support for stands for signal and switch operating connections comprising a base-piece, a ller or fillers, clamping means and centering means for the iller or fillers.

6. An end support for stands for signal and switch operating connections comprising a base-piece, a filler or fillers, a bolt and means for centering the filler or fillers about the bolt.

7. An end support for stands for signal and zo In testimony whereof I have signedmy z5 name to this specification in the presence of two subscribing witnesses.
