To all whom it Duty concern:

Be it known that I, EDWARD O. BERGHOE- FER, of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a new and useful Improvement in Elevators and Carriers, of which -the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

My invention relates to an elevator and carrier that is especially adapted for lifting and transporting coal or other material in buckets or merchandise in packages; and theinvention is directed specifically to means for automatically locking the carrier to stationary position on its track and for releasing it, permitting it to travel on the track, and to locking the pulley-block in and releasing it from the carrier.

The invention consists of the elevator and carrier and related devices and their combinations, as herein described and claimed, or the equivalents thereof.

In the drawings, Figure 1 is a side view of an elevator and carrier and related devices Fig. 2 is a top plan the related devices. Fig. 3 is an edge view of a pulley and its block forming a part of my invention.

In the drawings, A isa fragment of a beam adapted for and serving as one of the rails or track on which my improved carrier may run. Two parallel rails of this character are required to receive thereon the tread of the wheels of the carrier and to serve as a track on which the carrier may run from over the place where the load is obtained to the place of deposit thereof.

The frame of the carrier consists, advisably, of two plates of metal 5 5 in parallel planes and secured together in permanent relations to each other by cross-rods 6 6 6. Flanged wheels 7 7, fixed in pairs on axles 8 8, support the carrier movably on the track. The

axles pierce the plates 5 '5 and have their bear ings revolubly therein. A cable-supporting pulley 9 is preferably employed,'which pulley is mounted revolubly in the frame of the carrier medially and near the top thereof. A

hoistingpulley 10 is also mounted in the carrier-frame and advisably in the front portion thence over the hoisting-pulley 10, and therefrom to and over some distant pulley (not shown) and to some means for winding it up or drawing on it. The pulley-block 12, which is conveniently made of two parallel metal.

side plates connected together by short crossrods, is of less width than the carriage, so that the pulley-block can enter the space between the plates 5 5. The axle 14 of the pulley 13 is mounted revolubly in the side plates or walls of the pulley-block 12 and projects laterally therefrom such distance as to cause these extremities of the axle to engage the plates 5 5 when the pulley-block 12 is raised into the carriage between the side plates 5 5. For receiving the extremities of this axle 14 recesses 15 15, one in each plate 5, are cut from their lower edges upwardly and forwardly into the plates medially and at the rear of the hoisting-pulley 10. Guide-plates 16 16 are secured to each of the plates 5, the guide-plates being provided with edges that register with and continue downwardly and flaringly from the recesses 15, thus providing flaring months or recesses for receiving therein and guiding the projections of the axle 14 upwardlyinto the pocketed recesses 15 in the plates5 5. Although other laterally-projecting pins on the pulley-block 12 might be employed in the place of the projecting extremities of the axle 1 1 to enter the recesses 15, yetthe extended axle 14: is advisably so constructed and employed.

A carrier-latch 17, having a rearwardly-extending member provided with a catch 18, having a beveled terminal edge, is pivoted on the carriage-frame near its rear extremity,and the forwardly-extending furcate members 19 19 thereof are curved downwardly opposite to and over the front portions of the recesses 15 15. Straps 2O 20 are secured to the plates 5 5 over the front ends of the furcate members 19 19 of the latch 17 and serve as guards and stops to secure the members 19 in place tiltably. cated as to be adapted to be engaged by the catch 18 when the carrier on the track is A stop 21, fixed in the rail A, is so 10- above the place at which loads are to be elevated. The latch 17 is so mounted that by gravity the catch 18 is tilted up so as to engage the stop 21 when the carrier running rearwardly on the track comes thereto. The disposition of the parts is such that when the pulley-block 12 is elevated to the carrier, bringing the projecting axle 14 up into the recesses 15, the axle 14 contacts with the curved portions of the members 19, and the pulleyblock, being still further elevated by the cable, lifts the members 19, releasing the catch 18 from the stop 21. A pulley-block or load latch 22 is also pivoted on the carrierframe, near the rear end thereof, and its forwardly-extending furcate members 23 23 are provided with catches 24 24, so disposed as to be adapted to drop behind and engage the projecting ends of axle 14 when the axle ends are in the recesses 15, and thereby hold the pulley-block and its load on the carrier. The construction of the carrier-plates, including the upwardly and forwardly curved recesses 15 15 and the projecting extremities of the axle 14, is such that when the pulley-block, with its load, has been raised into the carrier and the catches 24 on the furcate extremities of the latch 23 have dropped down hehind the axle 14, as shown in Fig. 1, the axle 14, with the weight of the load, rests principally on the downwardly and rearwardly curved edges of the plates 5 5 at the lower sides of the recesses 15. This obviates great strain on the latch and permits of its being released with comparative ease. Straps 25 25 on the plates 5 5 serve as guards and stops for the front extremities of the furcate members 23 in their tilting movements. The rearwardly-extending portion of the latch 22 is provided with a beveled edge 26, adapted to be contacted by a pin 27 and to be depressed thereby as the carrier moves rearwardly after the beveled edge contacts initially with the pin. The pin 27 is fixed in any convenient permanent support. The relation of the pin 27 to the stop 21 is such that the latch 22 is tilted, raising the latch 24 and releasing the pulley-block,by the slightly continued movement of the carrier rearwardly after the catch 18 has passed the stop 21, thus releasing the pulley-block, which, falling by gravity, escapes from the carrier, and thereupon the carrier, starting forwardly, is stopped and held by the engagement of the catch 18 on the stop 21, while the pulley-block descends for and is elevated with a load. As the pulley-block and its load are elevated to the carrier the projecting ends of the axle 14 come in contact with the catch 24 and lift that catch, passing above and inside of it, and engage the members 19 of the latch 17 and lift it, releasing the catch 18 from the stop 21, and as the carrier runs forward on its track to the place of deposit of the load the lever 22 by gravity tilts, letting the catch 24 down behind the projecting ends of the axle 14,

thereby holding the pulley-block in the car rier against escaping downwardly therefrom.

The carrier is especially adapted for use with buckets which are hung on the lower end of the block 12 and are thereby raised with the block and transported on the carrier to and from a place of deposit of the buckets load. When buckets consisting of two valves or members that close together are employed,

as they are usually in unloading coal from vessels, a rope 29 is employed to manipulate the members of the bucket, and this rope runs over an idle pulley 28, mounted in the carrier. When the loads are light and rapid elevation and descent of the pulley-block and its load are desired, the cable 11 may be attached to the carrier and conveniently to a cross-rod, as 6, instead of directly to the upper end of the pulley-block, and in such case the cable will not run over the supportingpulley 9. The braces 30 30 are secured to the plates 5 and 16, respectively, and these braces, with the plates and cross-rods, form the carrier-frame.

What I claim as my invention is 1. In an elevator and carrier, a carrierframe having substantially parallel side plates provided with oppositely-disposed medial recesses extending upwardly and forwardly from the lower edges of the plates, a hoisting-pulley, a movable pulley-block and a pulley therein having an axle projecting laterally beyond the sides of the block, the axle being adapted to contact with and rest on the recess edges of the carrier-plates and be supported thereby, a cable running under the pulley of the block and over the hoistingpulley, a releasable pulley-block latch pivoted on the carrier and provided with a catch adapted by the gravity of the latch to fall behind and across the path of the laterally-projecting axle on the pulley-block, and means for uptilting the lever by the movement of the carrier and releasing the pulley-block.

2. In an elevator and carrier, the combination of the carrier-frame having side plates with recesses extending inwardly upwardly from the lower edges of the plates, an independent movable pulley-block and pulley, a pulley-axle projecting laterally beyond the pulley-block adapted to enter the recesses in the side plates of the carrier and to engage said plates, means for raising and letting down the pulley-block, a furcate gravity-tilting carrier-latch the furcate members of the latch being exterior to and pivoted on the carrier and adapted by gravity to engage a perma- I nent stop and to be lifted by the rising pulley-block and released from the stop, a furcate gravity-tilting pulley-block latch pivoted on the carrier adapted by gravity to engage releasably portions of the pulley-axle project- I ing laterally from the pulley-block, and means adapted by the rearward movement of the carrier to engage and tilt the pulley-block latch releasing the pulley-block.

3. In an elevator and carrier, a carrierframe having substantially parallel side plates with upwardly-extending recesses, me-

dially a pulley-block suspended from and movable toward and froznthe carrier, a pulley in the pulley-block, said pulley havingan axle projecting laterally beyond the walls of the block, and a carrier-latch and a pulleyblock latch, both latches being pivoted on the carrier so as by gravity to fall across the path of the projecting extremities of the block-pulley axle in said recesses.

4. In an elevator and carrier; a carrierframe having substantially parallel side plates and plate-connecting cross-rods, a cable-supporting pulley and a hoisting-pulley mounted in the frame,' an independent movable pulley-block and pulley, said pulley having an axle projecting laterally beyond the Walls of the pulley-block, a hoisting-cable attached to the pulley-block and running about the cable-supporting pulley and under the block-pulley and over the hoisting-pulle y, and means adapted automatically to engage the projecting extremities of the axle and hold the pulley block to the carrier; and other means adapted automatically to engage a stop and hold the carrier in place on its track, and to be engaged by the axle on the pulley-block and by the movement of the pulley-block to release the carrier from the stop.

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