SPECIFICATION forming part of Letters Patent No. 638,366, dated December 5, 1899.

Application filed June 14, 1899.

T0 ctZZ whom it may concern:

Be it known that I, PETER G. STRICKLER, of J anesville, in the county of Rock and State of Wisconsin, have invented certain new and useful Improvements in Elevated Carriers and I do hereby declare the following to,be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in elevated carriers, the object of the invention being to produce means for automatically locking and releasing the load from the carrier, which means shall be simple in construction, comprise a small number of parts, and which shall be effectual in all respects in the performance of their functions.

With this object in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claim.

In the accompanying drawings, Figure 1 is an elevation showing the parts (in full lines) in position to carry the load, the dotted lines indicating the positions of the parts when the load shall have been released. Fig. 2 is a detail View.

A represents the carrier-frame, which is made with upwardly-projecting arms a for the accommodation of wheels b, the journal of said Wheels being mounted in the upper ends of said arms and adapted to run upon the elevated trackway B. At suitable points on the trackway (usually at the terminals thereof) plates or bars 0 are secured to the under face thereof by means of bolts 0, and to each of said plates or bars an A-shaped cam O, having a horizontal portion or bridge 0 at its apex, is secured, said cam being made to depend into the path of a latch-lever D, pivotally connected to the carrier-frame A. The forward or free end of the latch-lever is bifurcated for the admission of the cam C and at its extremity is made with inwardlyprojecting lugs d, adapted to ride on said cam, thus causing the free end of said lever to be raised to release the carrier, as will be presently explained.

The latch-lever D is made with a downwardly-projecting tooth or finger 6, adapted Serial No. 720,536. (No model.)

to engage lugf, projecting from a jaw E, pivotally connected at a point below the lug f in the frame A. When the tooth or finger e is in engagement with the lugf, the jaw will be disposed in the position shown in full lines in Fig. 1 and the head 9 of a pulley-frame g (or other device which carries the load) will be engaged by said jaw and also by a diametrically opposite jaw F, which latter is rigidly secured to or made integral with the frame A. WVhen the parts are in these positions, the load will be supported by the carrier and the latter is ready to be moved on the trackway. When the carrier reaches its destination or the place where the load is to be discharged, the cam O at that point will enter the bifurcated end of the latch-lever D, and as the carrier moves forward the lugs 11 on said lever will ride on the cam andcause the lever to be raised, thus moving the tooth or finger 6 out of line with the lug f of the jaw E, and thereby releasing said jaw. The weight of the load will now cause the jaw E to move back and release the pulley-frame to which the load is connected, thereby releasing the load. The lugs d, riding on the horizontal portion 0 of bridge 0, will hold the latch-lever up and so as to give the pulley carrying the load plenty of time to drop. The weight of an arm h, projecting laterally from the jaw E, (preferably in path of the pivotal support of the latter,) will cause the jaw to move back farther than is absolutely necessary to release the head g, and the rearward movement of said jaw will be limited by a lug or stop 11, projecting from the frame A. The carrier is now ready to receive another load, assuming it to be at the startingpoint on the track, and will be held in this position during the elevation of the load, which latter may be accomplished in any suitable manner, by the engagement of the free end of the latch-lever D with one of the inclined webs j of the plate or bar 0, the lever being held up by engagement of the finger c with the lugfof the jaw E. When the head 9 of the frame or bail g enters the carrierframe A, it will pass the stationary jaw F and engage the arm h, projecting from the pivotal jaw, thus turning said pivoted jaw on its fulcrum until the lug passes the tooth or finger e, carried by the latch-lever D,whereupon said lever will be permitted to drop by its own gravity and the tooth or finger e become disposed in front of or in engagement with the lug f, thereby locking the jaw E. The head g of the frame or bail 9 will now be locked between the jaws E F and the load attached to the carrier and ready to be transported thereby.

My improvements are very simple in construction, easy to keep in repair, automatic in operation, and effectual in all respects in the performance of their functions.

Slight changes might be made in the details of construction of my invention without departing from the spirit thereof or limitingits scope, and hence I do not wish to limit myself to the precise details of construction here set forth.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

In an elevated carrier, the combination with a frame and a trackway, of a depending cam secured to the trackway, said cam having at each side, two inclined grooves and a horizontal groove connecting the inclined grooves,

a rigid jaw at the forward side of the inlet through which the load-carrier enters, a pivoted jaw in rear of said inlet, said pivoted jaw having an arm to engage the load-carrier and also having an arm adapted to project over said inlet, an upwardly-projecting lug on the pivoted jaw, a back-stop for the pivoted jaw, a lever pivoted in rear of the pivoted jaw and projecting over and beyond the latter, said lever having a bifurcated forward end to embrace the cam, lugs on said lever to project into the grooves in respective sides of said cam, and a tongue depending from the lever at a point nearer its pivot than its free end and adapted to be disposed in front of the lug on the pivoted jaw to lock the latter and to rest on the top of said lug to retain the lever locked in the cam when the loadcarrier is detached.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

PETER G. STRIOKLER.
