Application filedMarch 9,

To all whom it mag concern: Be itknown that I, RoBnR'r H. BnAuMoN'r, a citizen ofthe United States, residing in vltadnor, Delaware County, Pennsylvania,

' the sheave so that it will be counterbalanced and will be properly supported not only when the rope is taut, but also when it is slack.

A further object of the invention is to 'design the support so that it will accommodate itself to diflerent angles, according to the reeving of the rope.

A still further object of the invention is to provide a rigid lower brace, which is swiveled in its support 011 a wall, or other fixed structure.

While the invention is especially adapted for use in a storage plant in which there is a back wall, it will be understood that the device can be mounted on a post, or similar support, Without departing from the essen tial features of the invention.

In the accompanying drawings Fig. l is a view, in elevation, showing my. improved sheave support attached to the back wall of a coal piling floor; a

Fig. 2 is a sectional plan view on theline 2-2, Fig. 1; 1

Fig. 3 is a sectional View on the line 3 -3, Fig. 1;

Fig. 41- is a detached perspective view of part of the sheave support; and Fig. '5 is a view, partly in section, showing the lower bearing for the brace.

eferring to the drawings, 1 is a wall, or other support. 2 is the sheave carrier having a center block 8 which, in the present instance, has a rectangular opening 4;. A headed bar extends into the opening from the front of the block and through a swivel section 6to which is attached the two members of the sheave bearing 7. The sheave 8; is mounted between the two sections of the bearin and on a-pivot 9 in the form of a bolt. .txtending into the rear of the center block is a bar 10. having a series of perfoi'a srrEAvE surr'oar.

tioris 11 at its outer end for the pin 121:10111 which a counterbalance weight 13 is suspended. This weight tends to counterbalance the sheave when slack.

On the center block are two sets of lugs, the lugs of each set being spaced apart and and a portion of the rope pivoted to the lower set of lugs l lis a strut 15 made of heavy flat iron. The lower end of this strut is shaped in the'form ofa pivot 16, Fig. 5, and is bent at an angle so that it will pass vertically through a bracket 17 firmly secured to the wall, or other fixed support. The end ofthis pivot is threaded for the reception of a nut 18. This construction allows the sheave carrier to turn on the bracket and also allows a certain pivotal movement, as shown by dotted lines in Fig. 1. Attached to the upper lugs 19 is a chain 20 which is secured to'the wall by a U-bolt '21 or other fastening. This construction permits a movement indlcated by dotted modate itself to the ropeas the strut and.

chain will allow the support to have free movement, as indicated by dotted lines in Fig. 1. The balance weight will tend to maintain the sheave, andits bearing, in sub stantially a horizontal position. In some instances, a bar, similar to that forming the strut 15, may be substituted forlthe chain 20, but it is preferred to use the chain as shown. Z I

I claim: i a 1. The combination in a sheave support, ofa center block; a sheave at one end of said block; a weighted bar at the opposite end of the block tending to balance the sheave; a strut pivoted to the center block and'extending at an angle; a fixed bearing for the lower end of the strut; and a member connected to the upper portion of the center block and to a fixed point above the sheave support. c

2. The combination in a sheave support,

of a center block; a swivel mounted at one "end of the block; a sheave carried by the i l; a bar projecting from the opposite and of the block; a counterweighton said bar; upper and lower lugs on the center block; a strut pivoted to the lower lug and ua'llowthe sheave support to move laterally and to allow the counterbalance-Weight to hold the sheave in substantially a horizontalposition. v v

3. The combinationlin ,a sheavesupport, of a center block having a longitudinal socket opening .a headed bar extending into thewfron't end of said opening and secured to the blook;. a swivel mounted-on said bar; a sheave carried'by the-swivel; a bar extending into the rear end of the socket in the center block and secured to said block; a balance Weight mounted on the bar, said center block having upper and lower lugs;

a 'strut'in the form of a bar pivoted to the 'loWer lugs and terminating 1n a-plvot pm at an angle to the strut; a bracket having an opening through which the pivot extends; as fixed support for the bracket; and a chain attached to the upper lugs and to a bolt securedto the fixed support substantially the same distance above the center block as the bearing for the'strut.
