SPECIFICATION forming part of Letters Patent No. 660,998, dated October 30, 1900.

Application filed August 21, 1899.

To (1 whom it may concern.-

Be itknown that 1, ROBERT R. RAYMOND,

a citizen of the United States, residing at Boston, in the county of Sudolk, State of Massa- 5 chusetts, have invented a new and useful Improvement in Hoisting Apparatus, of which the following is a specification, reference being had to the drawings accompanying and forming a part thereof.

The present invention relates to hoisting apparatus, and is especially designed to .be used in connection with heavy ordnance for the purpose of elevating individual charges from a lower plane, as an ammunition storage- 5 room, to a higher plane, as the point of support of a gun.

The object of the invention is to provide a simple means whereby the heavy cartridges or shells may be easily handled and placed upon an endless traveling device and automatically discharged at the point of delivery in an easy manner, so that there shall be no danger of explosion of the charges. At the same time the construction embodying the invention is such that the discharging devices are of the simplest character aud'operate positively.

In the drawings I have illustrated econ struction emoodying my invention, which, 0 while it"'shows one form of my invention which I deem now'to he a preferred form, I do not wish to be limited thereto, as the construction may be susceptible of variation without departing from the spirit of the in- In the drawings, Figure 1 is a view partly in side elevationand partly in vertical crosssection. Fig. 2 is a detail view in elevation of one of the carriers. Fig. 3 is an elevation 40 view of theloading devices looking in the direction of the arrow of Fig. 1. Fig. 4: is a plan view of the loading devices.

Like letters of reference refer to like parts throughout the several views of thedrawings.

Referring to the drawings in detail, 1 designates-the lower frame of the construction, which may beef any suitable form and supports-a shaft 2, on which are keyed sprocketwheels 3.

5o 4 designates the upper shaft, upon which are secured the upper sprocket-wheels 5.

Serial No. 727,875- (No model-l -maiutain while they pass a portion of the curved surface of the upper sprocket-wheels and, in fact, until they come in contact with the tilting or tripping device to efiect the discharge. of the load. Each of these carriers consists of a bottom plate 10 and a tailpiece 11, being secured to the chains by theside pieces 12; but other forms of carrier may be used that will perform the functions herein described.

The means whereby each of the carriers automatically picks up its load and discharges the same consists of the following: Near the upper end of the travel of the chains and between the upward and downward ascending and descending chains is a guide-piece 13, which receives the carriers immediatelyafter they have discharged their loads. Atthe time of discharging the load the carrier is in inverted position, and this guide 13 operates to 8d maintain it in that position and at the same time to deflect it from the central vertical line of the apparatus until atthe end of said guide 13, which iscurved outwardly, the carrier, by reason of the fact that its center of gravity is gradually deflected upon the opposite side of'the central line of the descending chains, is

thrown upon the guideway or track 14, which maintains it in inverted position throughout the remainder of the downward travel. The reason for this is that the load which the carrieris to take up is taken on at the lowermost point of the chain and the carrier is to scoop up or pushalong its load until it is entirely supported upon the carrier.

The means whereby the load is thrown in the path of the carrier and automatically taken upgthereby consists of the following: At the lowermost point of the travel of the two chains is a loading-table 15, provided with two pivoted segments 16, haviu g a curved face 17,-feoinciding with the circumference of ;.:su:rface 17 of the pivoted segments.

This loading-table is also'provided with two upstanding arms .18, which are provided with acurved portionlll, which constitutes acontinuation oft-he curved The segments before referred to are secured to a i -shaft 20 andar'e moved by any desirable "-means, as 'a ha'ndle21. =Any uitable locking in the drawings I have shown bolt 22.

device may be provided for this handle, and

asimple pushllh'e downward guide 14 terminates .in a curved portion 23, which meetsa curved from chain to chain.

It is evident that-the loading devices may be variously modified so long as there are present a platform for the load at the lowermost path of travel of the carriers, a table or other means for feeding the load to the platform either separate from or integral with the platform, and an inclined or curved surface or guide, which may be either part of the platform or separate therefrom, as shown inv the drawings, the purpose of whichis to keep the load in engagement with the carrier until it is supported thereby or t'heir'equitralents. '3

As the carriers ascendeupon the endless chains and approach the upper spr9cket= loading-platform 24, extending clear across fwheels their vertical positionjs maintained by reason of the method ofsuspension' until the load has passed the central shaft band ings the load is-take .the', tailpiece" 1l of the carrier comes in contact with tiajtf 'haft 4. The further movement of en chains then eflfects a tilting' of the ca' r,-= as-illu strated inFig. 1,,so thatthe load s discharged. upon the receiv ing-table 25. ffitter this,a;as before described," the carrieris car'ried downward in an inverted positioniby meansphth'e guides 13 and 14.

In the mechanism-'1 lnsti'ated in the draw- I t uplas follows: A suitable shell or other load is placed'upon the table 15, the. segments 16 are lowered by means of the'cranlf21, and the shot or. other "load rolls forward upon said segments,and as the segment's are-brought up to a normal positi'on the float-dis, throw'nupon the loadingplattorm directly in the path of travel of the carriers and the segments are closed or locked by means of the 'pu'sh-bolt 22. The next carrier which comesalong will'engage or scoop,

up theshell or other object constituting the .load and carry-it toflthej point of delivery, as

before explained It for anyreason the segments 16 shouldjnot be locked in their closed or normal position, the carrier-would simply pushdthe load oifi; of the wayand would pass on without'takiiigj'it'up.

. I have 'aho, e illustrated auddescribod-the preferred foirms of my construction and'of the severalpartsthereof. Itis evident, however," thatvarious changes and modificatiens of the same may-be made without departing from the spirit of my invention,and I do notintend, theretore, to limit myself to the specif c coneeoeos struction shown.- I intend also when using the word chains in the specification and claims to include therebythe use of a single chain when desirable.

The ad vantages of my construction will be apparent. The loads, which may be shot or anything else, are engaged by the carrier at! the lowest poi nt of its travel and carried clear around to the opposite side of the endless chains and automatically discharged -there by means at the same timesimple and positive. Also the labor required for loading the device is of the very smallest degree and. the pick-up is automatic.

4. In an apparatus of the character described, endless chains,one or more carriers freelysuspended between said chains,.a platform at the lowermost path of travel .of the partly-inverted carriers, means forpresenting the carriers to the platform inapartlyinverted position, and movable guides for automatically keeping the load in engagement with the carrier until supported thereby, substantially as specified.

i 12. In an apparatus of the character described, endless chains, one. or morecarriers deflecting and inverting the carriers, anouter guide for maintaining the carriers in inverted freely supported thereon, an inner guide for position, and a-loading-platformat the lower and inner end of said guide, said platform being upwardly inclined in the direction of the upward path of travel of the carriers.-
