CONVEYING APPARATUS.

Specification of Letters Patent.

Patented Sept. 10, 1907.

Original application filed December 20, 1906, Serial No. 348,760. Divided and this application filed March 9, 1907. Serial ho. 361,616.

To all whom it may concern:

Be it known that we, ADRIAN HALL and JOHN M. HALL, of Greenfield, county of Hancock, and State of Indiana, have invented a certain new and useful Conveying Apparatus; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like letters refer to like parts.

This application is divided out of a former application filed by us for a conveying apparatus, Dec. 20, 1906, Ser. No. 348,760.

The object of this invention relates to improvements in conveying means whereby the load may be both conveyed horizontally and vertically, and a means operated by a single cable for accomplishing these two functions.

The nature of this invention will be understood from the accompanying drawings and the following description and claims.

In the drawings Figure 1 is a side elevation of the apparatus with the lowered position of the load shown in dotted lines. Fig. 2 is a front elevation of one of the cable-carrying frames and braces therefor, parts being in section. Fig. 3 is a side elevation of the carrier on an enlarged scale, parts of the cables being broken away. Fig. 4 is an elevation of the right-hand end of said carrier with the cables in section. Fig. 5 is a central vertical section longitudinally through the middle portion of the carrier parts being broken away to show the position of the parts when the load-hanger has been lowered away from the carrier. Fig. 6 is the same with the load-carrier in its elevated and locked position. Fig. 7 is a transverse section on the line 7-7 of Fig. 6. Fig. 8 is a horizontal section on the line 8-8 of Fig. 7. Fig. 9 is a side elevation of the brake mechanism.

In detail an operating cable 16 is stretched over the frames 17 and 18. These frames are A-shaped, being formed of two inclined side bars connected at the upper end by a cross bar 19. The frame 17 carries a loose pulley 20 on a rod 21 over which the supporting cable 16 extends. The frame 18 is held in position against the pull of the cable 16 by a stay 22. The cable 16 supports a load-carrier 23 by means of a pair of pulleys 24 that travel on said cable. It is moved in one direction by cable 45, which at one end is secured to said carrier and passes over the pulley 46 in the pulley block 47 that is suspended from the cross bar 19 of the frame 17, as seen in Figs. 1 and 2. While said load-carrier is moved in one direction by said cable 45 as it is drawn by suitable means, the carrier is moved in an opposite direction by the cable 75 which extends from the drum 76. It passes over the pulley 77, seen in Fig. 2 and over the pulley 78 mounted in bearing 79 at the side of the carrier 23, as shown in Figs. 3 and 4,- and thence about the pulley 89 mounted in connection with the frame 18 and returning, said cable 75 passes over pulley 80 mounted in the lower right-hand corner of the carrier 23, as shown in Fig. 3, under the pulley 81 mounted in the hanger 82, and then is secured at 83 to the lower left-hand corner of the carrier 23, as appears in Figs. 1 and 3.

The lower hanger 82 has a hook 100 on its lower end to which a load 101, shown by full and dotted lines in Fig. 1, may be attached. Said load hanger is locked in its upper position by means of a hammer-shaped catch 102 that is fulcrumed at 103 to the carrier in such manner that the lower-projecting end thereof will extend below the head 104 on the rod 105 extending upward from the upper end of said hanger. Said hammer-like catch 102 is locked in its engaging position by a locking block 106 that drops down upon a bar 107 which projects horizontally from the catch 102 and in line with its fulcrum so that said block 106 will resist any lateral movement of the header upper end of the catch 102.

While the load hanger is in its upper and locked position, as shown in Figs. 1, 3 and 6, the load may be transported to the desired position of discharge or deposit. At that point it may be unloaded by releasing the lock 106 and catch 102 and then releasing the actuating cable 75, so that the weight of the load will carry it down to the dotted line position shown in Fig. 1. Said lock 106 is moved from its locking position by a finger 108 that extends under lugs 109 projecting inwardly from the two side plates of said lock 106, and said finger being fulcrumed on a shaft 110 which carries on its outer end a lever 111, from which a rope 112 is suspended, whereby said lever may be drawn down, which'will cause the finger 108 to elevate the block 106 above and out of engagement of the catch 102. When this happens the load may be lowered by releasing the cable 75. In this connection it is noticed that the carrier 23 is formed of two connected side bars, as shown in Figs. 7 and 8. And it has a flaring opening at 113 that permits a rounded head 104 to-enter the space between the side plates of the carrier to the position shown in Fig. 6, to be again locked. This upper or return movement of the hanger is caused by tightening the cable 75.

From the foregoing it is seen we have a comparatively simple and economical device for conveying merchandise or other articles from boats or other conveyances or from one place to another and depositing where desired. The depositing of the load is accomplished by controlling the means which actuates cable 75, that being a drum 76 on a shaft 84 mounted 011 a frame 12, provided with means for being actuated, which means are not here shown. In order to stop the load or hold it at a desired elevation it is necessary that an effective brake mechanism be provided. To this end we provide sprocket wheel 115 on the end of the shaft 84 of the drum 76 with a chain 116 running therefrom over the sprocket wheel on a shaft 118. A

friction Wheel 1520 is rigidly secured on said shaft 118 so as to be engaged by the brake shoe 121, on the shaft end of a pedal 122 that is fulcrumed at 123 to the side of the frame, as shown in Fig. 9. 125 and 126 are brace rods to hold the posts in place.

What We claim as our invention and desire to secure by Letters Patent is:

rier in an opposite direction, a pulley on said carrier over which one of said cables passes, a loadhangor, a pulley in said load hanger riding upon the portion of said cable lying between said pulley on the carrier and the point at which said pulley is fastened to the carrier, means on the carrier for catching and holding said load hanger in its ele vatcd position, a lock for engaging and locking said means so that it will hold said locking means in its elevated position, and a lever for removing said locking means from its locking position whereby said load hanger may be drawn downward.

In witness whereof, we have hereunto aflixed our signature in the presence of the witnesses herein named.
