WEIGHT FOR CHEST-MACHINES.

SPECIFICATION forming part of Letters Patent No. 772,906, dated October 18, 1904.

Application filed February 24, 1904. Serial No. 195,103. (No model.)

To all whom it may concerm.

Beit known that 1, ROBERT REACH, a citizen of the United States, residing at Philadelphia, Pennsylvania, have invented certain new and useful Improvements inWeights for Chest-Machines, of which the following is a specification.

My invention relates to weights of the kind used in connection with chest -'weight machines in which a series of weights are permanently mounted on guide-rodsand are removably connected one to the other, the

weight on thepulleys being varied by connecting or disconnecting the weight at the bottom of the series. These weights as now constructed are provided with a recess in the upper side and have alug projecting from the lower side, the lug of one weight extending into the recess in the weight next below it, where it is secured by an eccentric lever engaging the lug. This method of securing the weights together-has been found. unsatisfactory because of its susceptibility to the'vibration and jar of the weights when the machine is in use, thus causing the lever or catch to gradually work around until the weight is released and drops.

The object of the present invention is toovercome this ob ection and to provide a stronger catch. This is accomplished in the manner hereinafter described, and more par ticularly pointed outin the claims.

Referring to the drawings, Figure 1 is a plan view of a weight embodying my invention. Fig. 2 is a similar View, partly broken away to show the locking mechanism. Fig. 8 is a sectional view showing two weights locked together.

In carrying out my invention I employ a weight A, having the usual holes a for the guide-rods and a cut-away portion 6 in its rear side to afford a passage-way for the pulleyropes. This weight I provide on its upper surface with a recess C, which is preferably of the shape shown and has its edges beveled, On the opposite surface I form a lug or projection D of a size and shape corresponding to that of the recess C. In this double-ogee shape or contour. The into-- rior of this eXtension'B is cut away to form a chamber E, in which is located a sliding plate F, having the pins or bolts f extending through the openings 0 in the rear of the chamber into the recess C for the purpose of engaging the recess (Z in the lug of the weight next above. The sliding plate F has an open ing Cr, in which the operating-cam 9 works. This cam is secured in place by the bolt or screw/2 extending through the sides of the chamber E, and is provided with a-handle H, extending beyond the edge of the weight for operating it.

The operation of the device will be readily understood. When it is desired to add more weight to the'pulleys, the weight-carriage is lowered until the lug D of the lowermost weight is seated in'the recess C of the uppermost of the idle weights. TheleverHis then thrown over, forcing the bolts f through the openings in the lugs and into the cavities v? in the opposite side of the recess C, thus giving a solid connection which is very strong and which no amount of vibration or jarring can loosen.

What 1 claim is 1. An article of the class described, comprising a weight having a recess in one face and a ing on the opposite face, a projection on, the front of said weight and means carried by said projection for locking said weight-to .an adjacent weight, substantially as described.

prising a Weight having a recess in one face and a lug on the opposite face, a projection on the front of said Weight and sliding bolts carried by said projection and extending into said recess, substantially as described.

t. An article of the class described, comprising a Weight having a recess in one face and a lug on the opposite face, an outwardlyextending portion on one side of said Weight, a chamber in said outwardly-extending portion, bolts mounted in said chamber and ex tending into said recess and a cam for operating said bolts, substantially as described.

5. An article of the class described, comprising a Weight having a recess in one face and a lug on the opposite face, an outwardlyextending portion 011 one side of said Weight, a chamber in said outwardly-extending por- ROBERT Rl 1A( )1 I Witnesses:
