WALL EXERCISING APPARATUS.

Specification of Letters Patent.

Patented Feb. 11, 1913.

Original application filed December 8, 1910, Serial No. 596,308. Divided and this application filed February 8, 1912, Serial No. 676,248. Renewed January 6, 1913. Serial No. 740,544.

To all whom it may concern:

Be it known that I, ROBERT REACH, citizen of the United States, residing at Springfield, Massachusetts, have invented certain new and useful Improvements in WVall Exercising Apparatus, of which the following is a specification, which is a division of application Serial No. 596,308, filed December S, 1910, exercising apparatus.

My invention relates to weight carriages.

for wall exercising machines.

In weight carriages of the under-lift type an objection has been experienced in that the weight sect-ions are liable to drop from the carriage or from the section next above, this being due to the release of the locking device between the sections because of the vibration of the weight carriage, and I have sought to remedy and eliminate this vibration by my improved construction and also to simplify the construction of the weight sections and the locking means between them.

The invention consists in the features and combination and arrangement of parts hereinafter described and particularly pointed out in the claims.

In the accompanying drawing, Figure 1 is a front view of the lower portion of an exercising machine embodying my invention, and Fig. 2 is a side view of the part shown in Fig. 1; Fig. 3 is a sectional view through the weight sections, the carriage being shown in front elevation; Fig. 4 is a plan view of one of the weight sections.

IVhile I have illustrated my invention in connection with a wall apparatus having a pair of weight carriages one behind the other, it will be understood that I do not limit myself in this respect.

In the drawings, 3 represents the guide rods of the wall apparatus, and 13 the weight carriage consisting of a plate having lugs or bosses 15, through which the guide rods pass to guide the carriage in its vertical movement.

11 indicates the weight carriage pulley mounted on the weight carriage and this pulley instead of being arranged with its axis in the same plane with the plane passing through from side to side, and in which the guide rods lie, is arranged with its axis extending from front to rear, or at right angles to the plane of the guide rods. The

advantage secured by this over the arrangement of the weight pulley, as heretofore used, is that the points of suspension on the operating rope are brought close to the guide rods instead of at a point centrally between them, and this has the effect of eliminating vibration.

In the old form in which the pulley lies with its axis in the plane passing through the side guide rods the weight carriage as it moves-up and down along the guide rods is liable to vibrate or tip because the point of support or contact of the weight pulley with the loop of the rope being in effect a pivot point, and being centrally located between the guide rods, will allow lateral oscillation of the weight carriage, and cause it to bind first at one side and then at the other upon the guide rods, thus causing more or less vibration. The disadvantage of this vibration is that aside from irregularity in the movement of the weight carriage, the weight sections are liable to be dropped for the reason that the vibration will cause the lock or fastening device between one weight section and the next above or between one weight section and the carriage plate to be loosened, allowing the weight sections to fall. I have also improved the construction and arrangement of the weight sections and their locking devices, as will now be described. The weight carriage 13 is provided with a lug having a head 30, adapted to pass down into a recess in the upper weight section 31, wherein the said lug is locked by a slide 32, carried by the weight section and having its ends projecting at 33 and provided with enlargements so that by striking these enlargements with the. foot the slide may be shifted in one direction or the other so as to lock the weight section to the carrier or to unlock the same.

The slide is shown in plan view in Fig. 4 and it is slotted longitudinally to receive the guide bars 3 and allow movement thereon. The slide is held to the weight section by a cover plate 34 secured by screws 35. Each section, except the lowermost, is provided with a lug 30 similar in all respects to the lug of the weight carriage and adapted to pick up or release the weight section next below it. It will be observed that the weight sections are of elongated form and where two Weight carriages are employed as shown, the Weights of one carriage lie par- ,v allel to those of the other and occupy comparatively little of the room from front to rear. An additional advantage of my arrangements of the pulleys is that the weight carriage may be located close to the wall together with the guide rods and brackets.

hat I claim is 1- 1. In combination in an exercising machine, a Weight carriage and a weight section attached thereto removably, said weight carriage having a projecting lug to enter the weight and a slide movable longitudinally on the Weight section for engaging the said lug to secure the weight section to the weight carriage, substantially as described.

2. In combination in an exercising machine, a weight, a carrier therefor and means for attaching the weight removably to the carrier comprising a slide or plate on the weight having its ends projecting to be pressed upon and slide longitudinally, substantially as described.

3. In combination in an exercising machine, a weight carriage, a recessed weight to receive a lug from the carriage or weight above, a slide or plate to engage said lug, and means to hold the slide in place, substantially as described.

In testimony whereof, I affix my signature in presence of two witnesses.
