To @ZZ whom 25 may concern:

Be it known that I, OHARLEsJ.' I-IoRGEN, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn,

in the county of Kings and State 'of New- York, have invented va new and Im roved Hoisting and Conveying Apparatus, o which thefollowing is afull, clear, and exact' description.

My invention relates to a device for hoist-l ing and conveying `purposes in general, and is the upper side of theblock, and is provided especially applicable `.to loading andunload-y ing ships. p p

The invention comprises a cable or'similar` flexible elementplaced onanineline and af carriage mounted on the cable and adaptedy to move along it, the carriage being provided with automatic means for. manipulating. a

pulleyto assist in the several operationsv of' 2o loading and unloading.

the hoisting apparatus with parts in section to show interior construction. Fig. 3 is a similar viewof the carriage. Fig.- l4 is a similar vview of the upper block, sectional view on the line 5.5 of Figi 3.

Fig. 1 shows a wharf provided'wth av block? 10, connected with a stationary support in: any desired mannery and having a cableor` (other flexible element 11 secured thereto,

This cable passes' upwardly at an angle of about twenty degrees to a block 12 and through the same to a windlass13 on ther boat. The block 12 is preferably connected with the mast of theboat by means of two y short cables 14, constituting a triangle, and a halyard 14a from the masthead, hooked to with pulleys15 (shown in dotted lines in Fig. 4)`-for guidingthe cable 11, Riding on the cable 11 is a carriage 16, to whichis secured the end of acable 17. This c'ablepasses under a-.pnlley 18, which is vertically movable 'with respect to the carriage and is designed Y to carry aloadfv The cable 17 then passes:

f Specification of Letters Patent. Application ined May 13, 1905. semi 110.260.243;

Figure 1 is a perspective view showing af `boat iitted up with an apparatus embodying the principles of :I ny'invention. Fig.` 2 is af yside elevation, partly in section, of a block? constituting v.an anchor for the lower end of? and Fig. 5 isa- Patented March 2o,19o6.

lthroughthe carriage'tov the block 12 and from there down to a hoisting-engine 21 on the boat. The block 12 is provided with a pulley 22 for guiding the cable and the carriage with a pulley 23 for the same'pur'pose.

The carriage is mounted'on wheels 24, runningon the cable 11. 1 Eachof the'blocks has 4a buffer 25 for yieldingly resisting the jar of i the carriage when it strikesit. provided vfor automatically locking the car-V riage to each blockwhen it strikes. For this purpose the block 1 0 is constructed with a cavity 26, having a pin 27, passing transversely across`it. L

On the" carriage is located apivoted lever y 28, having acatch 29', adapted tov engage `the Y pin'27 when broughtinto proper position. A

spring 30 normally holdsv the hook in proper position for engagingthe pin'.y l Av 'pin 31 isl employed on the carriage tollmit the movement of the lever vin one' direction. The other block is provided with a cavity 32, having'a pin 33, and on the carriage is mounted a s ec-- l 'ond lever' 34, having a catch 35 for engaging the last-'named pin.- In, order to operate Meansare also these levers to automatically unlock them at the* proper times andA to support the load `while thecarriage is moving along the cable *11, the vfollowing mechanism 1s provided: Transversely'across the carriage extends a shaft 36. On the outside ofthe carriage two bars 37 are placed, each bar having an elongated slotthrough which they are pivoted on the shaft 36. VThis permits a vertical motion as well as a swing motion Each of the bars. is

providedwith a 'channel 39 upon its inner surface. This'channel is formed4 with three camp-surfaces 40, 41, and 42, the latter being located at the top of an extension 43, which 1s provided with two other cam-surfaces44 and 45 on'the right andsleft hand side thereof. The carriage having a vertical slot 46 adjacent to the position occupied by the channel 39 vwhen it is in normal position, a pair of studsy .I 47 on a frame 48, which supports the pulley 18, isfree to move upwardly into thechannel 39. This arrangement is provided so 'that the pulley 18 and the weight supported there- IOO by can becarrieddirectly by the carriage through the instrumentalityof the cam-surface 42, on which the stud 47 is adapted to rest. The carriage is also formed'with aslot les 49 forreceiving a lstud "50, mountedon ay pro'- jection 51 on the arm 37. This stud engages a reciprocating bar 52 and is operated by it. This bar has an elongated slot 52a, in which operates a stud 53, mounted in a stationary position on the carriage.

At the upper end the arms 37 are provided with a transverse pin 54, which passes through a slot 55 in the lever 34. This slot is formed With two depressions 56, large enough to receive the pin 54. A spring 57 normally holds the lever 34 in the proper position for keeping the catch 35 low enough to engage the pin 33- when the carriage moves against the block 12. The block 12 is provided with a nose or projection 58, the upper surface 59 of which is curved and inclined for a purpose which Will be stated below.

Springs 60 are employed to suspend the bars 37 and keep them in central position, but permit them to yield. These springs are connected with the pins 61, which can reciprocate in slots 62 in the carriage 16.

The operation of the device will now be described. Assuming the studv 47 to be in the channel 39 and resting on the surface 42, as shown in dotted lines in Fig. 3, and that the cable 17 is being let out, so that the carriage slides down the inclined cable 11, it will be seen that when the carriage engages the buffer 25 the end of the bar 52 will engage the outer surface of the block 10. This pushes the bar rearwardly with respect to the carriage and swings the arms 37 about the shaft 36, so that the surface 42 will move out of the way of the stud 47. This removes the support of the latter and it drops out. The weight of the pulley 18 now causes it to descend, taking with it the cable 17, which is being paid out at the other end under control of the brake. The descent of the pulley to the desired place will be readily understood. In an obvious manner the catch 29 engages the pin27 when the carriage reaches the position described above, and also when the bar 52 is pushed inwardly the pin 54 engages the left-hand slot 56. This holds the arms 37 in the position in which they were forced by the bar 51. As the arms 37 are normally held in an elevated position by springs 60, the ascent of the pulley 18 when the hoisting-engine is operated to raise it will cause the studs 47 to slide up the Ycam-surface 45 and engage the cam-surface 41 .whi ch at that time is in registration with the slot 46. Further force applied by the hoisting-engine will operate to cause the studs to engage the bar 28, which is located behind the slot 46, and disengage the catch 29 from the pin 27. This allows the carriage to move upwardly along the cable, and when this operation commences the studs 47 will settle .back onto the cam-surface 42 and this will pull the arms 37 into their lowermost position, .bringing them also back to central position, with the pin 54 between the two slots 56.

When the carriage reaches the block 12, the catch 35 is at iirst in such a position that it cannot engage the pin 33 on account of the weight on the arms 37 g but the continued operation of pulling on the cable 17 forces the studs 47 to rise against the cam-surface 4() and then to drop along the cam-surface 44 and force the arms to the rear, so that the pin 54 will engage the right-hand depression 56 and the pulley will slide oif from its support. The engine is stopped at this time and the weight lowered to the deck by the ordinary means, it being controlled as usual, by a brake or the like. Before this occurs the carriage is forced up the incline 59, so that it is left in a position with its front lower surface on the inclined surface 59, and as soon as the Weight is removed from the surface 42 the spring 57 is free to act to force the catch into engagement with the pin 33, so as to lock the carriage to the block. In raising the load and pulley to the block again theiirst operation is to cause the studs 47 to engage the surface 41 and drop back against the surface 42 when the strain on the cable caused by the hoisting-engine is removed. As the carriage is held up by the surface 59 until this time, it will be seen that the weight of the pulley and load thereon will free the catch 35 from the pin 33 and allow the carriage to slide down this incline and then run down the inclined cable. From this point the operations described above can be repeated.

Among the advantages of theinvention are the fact that the carriage runs on a cable which can be adjusted from the boat to suit the circumstances, and a single operating-cable is used to operate the carriage, all changes of direction and motion from vertical to inclined being effected automatically by the mechanism described.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. `A hoisting and conveying device, comprising a pair of blocks located at a distance from each other and adapted to be connected by an inclined cable, the upper of said blocks being provided with a lateral projection having an inclined curved upper surface, and a carriage movable from one block to the other and adapted to be supported on said inclined surface.
