SAMUEL MICHAEL JENKS, OF MADISON, SOUTH DAKOTA.

OVERHEAD CARRIER.

SPECIFICATION forming part of Letters Patent No. 673,270, dated April 30, 1901.

Application filed January 14, 1901. serial No. 43,239. \No model.)

To all whom it may concern.-

Be it known that LSAMUEL MICHAEL J ENKS, a citizen of the United States, and a resident of Madison, in the county of Lake and State of South Dakota, have invented a new and Improved Overhead Carrier, of which the following is a full, clear, and exact description.

This invention relates to an overhead carrier adapted especially for carrying hay and analogous loads from one place to anotherfor example, from a wagon into a barn for storage.

The carrier is adapted to be used with a sling, which may be of any desired construction, but which is preferably of that construction described and claimed in my copending application for patent on slings for overhead carriers, filed January 29, 1901, Serial No. 45,190.

This specification is a specific description of one form of the inventiomwhile the claims are definitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is an end elevation of the carrier with the track in section on the line 1 1 of Fig. 3. Fig. 2 is a side view of the carrier. Fig. 3 is a longitudinal section thereof, showing the latch of the carrier locked with the sling; and Fig. 4 is a section showing the latch in unlocked position.

0. represents the track on which the carrier runs. This track is suspended by hangers a and is provided at a certain predetermined point with a downwardly-projected stud or pin a the latter for coaction with the carrier, as will be hereinafter explained. The detailed construction of the track is set forth in my copending application for patent on overhead tracks, filed January 14, 1901, Serial No. 43,240. Thecarriercomprisestwo sideframes b, which are fastened rigidly together by tiebolts or the like I) and which have secured between their lower portions a casing c, having a hell or funnel shaped skirt 0 at its lower end, this skirt projecting below the side frames 79 and having an open lower end. Wheels 5 are carried by the side frames 1) and run on the track a, as shown. By these means the carrier is mounted to move freely gravity attending the arm (1 along the track, the side frames 12 straddling the track, as shown. Within the casing c a. latch d is mounted to rock upon a pin d, fixedly carried in the casing. The latch (1 comprises a hook d an arm d adjacent to the hook, and an arc-shaped track d, terminating at one end in a cavity (1 and at the other end in a shoulder (i The parts are so arranged that the latch (1 will normally hang in the position shown in Fig. 4, which position is taken owing to the preponderating force of In Figs. 3 and 4, e represents an eye forming part of the sling which works with the carrier. Assuming thatthe parts are in the position shown in Fig. 4, the eye 6, moving upward, will engage the arm 01 and throw the latch into the position shown in Fig. 3, in which position the hook 01 is engaged in theeye e.

Acting with the latch d is a lock f, mounted in the upper part of the casing c and arranged to rock upon a pin f, fixed in the casing c". This lockfcomprises two arms f and f the latter having a hook-shaped end and the two arms being spaced apart a distance approximately equal to the length of the detent or stud a on the track. The lockfis also provided with a roller f located at its lower portion and adapted to run on the track (1 of the latch d. The shoulder d of the latch strikes the roller f and limits the movement of the latch toward the open position, (see Fig. 4,) and when the latch moves oppositely its movement is checked at the proper time and the latch is held securely in closed position by the engagement of the roller f within the depression or cavity d in the latch. (See Fig. 3.) Therefore when the latch moves from the position shown in Fig. 4 to that shown in Fig. 3 the track d runs along the roller f and the lock drops into the position shown in Fig. 3, whereupon the movement of the latch 01 will be finished. When in this adjustment, the lock f serves to prevent the return of the latch to the open position. (Shown in Fig. 4.)

Assuming now that the parts are in the adjustment shown in Fig. 3 and that the carrier is moving in the direction of the arrow indicated at gin Fig. 3, the hooked end of the arm f of the lock will engage with the detent a and the lock will thereby be thrown to the position shown in Fig. 4. This movement of the lock releases the latch and permits the sling, of which the eye e forms a part, to drop from the carrier. The abovedescribed movement of the lock results, further, in the upward movement of the arm f o thereof, causing this arm to act with the arm f, the two embracing the detent t and securely locking the carrier therewith, preventing the carrier from moving farther on the track until the parts are moved from the position referred to. The carrier is thus stopped and held stationary during the descent of the sling to discharge or receive its load, as the case may be. The look returns to the position shown in Fig. 3, when the latch is returned to its closed or inactive position.

The carrier is provided with sheaves h, mounted on transverse pins h and arranged, respectively, at its sides, the sheaves serving to carry the ropes for operating the sling and also for hauling the carrier, and these sheaves h coact with the sheaves i, also mounted on the carrier, the sheaves 1; serving to guidethe and at the other end in a stop, and a lock for the latch, the lock having a part engaging the track and. adapted to enter the depres-.

pivoted in the casing, said latch being provided with a hook, an arm and an arc-shaped 5 track terminating at one end in a shoulder and at the other end in a depression, and a pivoted lock above the latch, said lock being 1 provided with two arms, one having a hook- I shaped end, and with a roller adapted to run on the" track, substantially as described.

3. The combination of a track, a stud carried thereby and projecting therefrom, a carrier running on the track, alatch pivotally mounted in" the carrier andcomprisinga hook and an arm juxtaposed to eachother and also comprising an arc-shaped track with a cavity or depression at one end, and a shoulder at the other end and a look having apart engaged with the track on the latch and capable ofentering the depression in the latch, to hold the latch in closed position and ,to engage the shoulder to" limit the opening movement of the latch, the lock having two juxtaposed arms' c'apable of straddling the detent on the track to hold the carrier stationary, the dete'nt-lyin'g in the path of the arms; on the lock;

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

SAMUEL MICHAEL JENKS.
