ELEVATOR AND CONVEYER.

SPECIFICATION forming part of Letters Patent No. 465,198, dated December 15, 1891. Application filed March 5, 1889. Serial No. 301,935- (No model.)

To all whom it may concern.-

Be it known that we, FRANK T. PATTERSON and ALPHONSE FELDPAUOHE, both of the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Ele vator and Conveyer, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part of this specification.

Our invention relates to mechanism for conveying coal or other material, and particularly to a conveyer adapted to receive coal and other material from a railway-car and convey it to a point or points at a higher level.

The novel features which we claim as of our invention are clearly pointed out in the claims, and will be best understood after an explanation of the drawings, in which-- Figure 1 is a side elevation of our device;

Fig. 2, an enlarged transverse section through two conveyer-boxes in the position they occupy in passing over the .upper guide. Fig. 3 is a cross-section on the line :20 a: of Fig. 1. Fig. 4 is an enlarged view of the catch which holds the bottom of theconveyer-boxes in" leading from the road-bed to the conveyer.

B B, 850., represents the framing on which our apparatus is erected.

C is a guide for the conveyer-boxes passing beneath the track A and hopper A, as shown. 0 indicates a sharp rise or elevation in this guide. V

D is a guide situated above guide 0; H, an

endless chain passing, as shown, over guide 0, thence. to and over guide D and back to guide G.

F is a sprocket-wheel which engages and drives the chain II. It may be situated at any convenient point in the guiding-surfaces, but most conveniently is placed between and at one end of the guides C and D, so as to vir-.

tually form a connection between them, and

the guides C and D should be made tooverilap each other at their other ends, as is shown in Figs. 1 and 5, where D D indicates the downwardly and inwardly curving end of guide D.

O in Fig. 5 is the guide 0.

G G, &c., are the conveyer-boxes, which are attached to chain H.

'The above-described arrangement of the track, guides, chain, conveyer-boxes, and actupwardly-curving end of v uating device is an important feature of our invention.

Preferably the guides O and D consist of two tracks, as is indicated in Fig. 3, and the chain H made of parallel links united to each other and to adjoining links by axles h, to which axles the conveyor-boxes G are secured as well as Wheels h, which run on the tracks of the guides. While the guides need-not necessarily consist of or support rails or tracks,

they must at all times present bearing-surfaces substantially equivalent to tracks for the wheels, and we will therefore refer to them hereinafter as tracks. Where the track 0 is horizontal or gradually inclined, the boxes can be secured to the axles hat both ends, as is illustrated in the case of the supplementary conveyer-boxes at the left of Fig. 1; but where a steep incline such as 0 exists in track 0 it is necessary to elevate or depress one end of the box above or below the chain in pass ing over it, and the box is thereforesecured to the axles h at only one end, and. means, such as hereinafter described, employed-for elevating or depressing the free endof the;

box.

g indicates a hinged bottom to the conveyer-boxes; g lugs extending from the edges of the bottom, and g catches pivoted to the sides of the boxes G, with hooked lower ends g adapted to engage the lugs g and hold the bottom g closed.

g are pins to prevent the catches g from turning too far, and g springs to hold them in proper position.

b is a tripping-lug secured on the guide 0 or an adjacent part of the frame, and which, by pressing against the extended upper end of the catch, causes it to move back and reto fall and dump its load of coal. b is a similar lug secured on or near guide D, which acts to re-engage the catch with the bottom of the boxes as they pass over guide D.

E, Fig. 1, is a supplemental track arranged at a short distance from and parallel to track 0 in its elevated portion 0', and converging toward it at the top and bottom of the said part 0'. WVhere, as in Fig. 1., the chain H is attached to the back ends of the boxes, this track E should lie below track 0, while, if attached to their front ends, the supplemental track should lie above 0, as is indicated by the chain guideL' in Fig. 5.

Considering, first, the arrangement shown in Fig. 1, it will be noticed that the boxes G are secured to the axles h at the upper rear corners, while wheels g are secured to their front lower corners. These wheels, running on the supplemental track E, which, in this construction, is as long or longer than the track 0, over which chain II runs, the distance between C and E at all points except at C is such astoenable the boxes G to run on the wheels h and g with substantially the same effect as though they were secured to I the modified construction of Fig. 5 the prov chain H at both ends. At 0 the track E diverges from the track 0 at the top and bottom of the incline to a distance such as will permit the front ends of the boxes to fall away from the chain to such an extent as to maintain the boxes nearly level, as is shown.

In the modification shown in Fig. 5 the boxes are secured to the chain at the front lower corners, and the supplemental track here serves to elevate the rear ends of the boxes as they pass up the incline 0. As shown, the supplemental track here consists of an endless chain L, passing over sprocket-wheels F F", one or both of which are driven to a speed such as will cause chain L to move with the same speed as chain I-I. Hooks Z, on the chain L, engage projecting arms or axle ends 9 on the back of the boxes, lifting them up and supporting them at a proper height while the boxes are passing over the incline C. It is of course evident that stationary tracks would have the same effect as chain L if similarly placed above 0'. The arrangement of a supplemental guide or track placed in relation to an incline in track 0, so as to maintain the boxes substantially horizontal, is an important feature of our invention.

It is advisable to so construct the boxes G that in passing over guideD they may do so without hanging down from the axles h, to which they are attached. In the construction shown in Fig. 1 this is accomplished by making the boxes of such length that their front ends will lie over projections g of the boxes in front, as is shown in Fig. 2, while in jecting rods or axle ends 9 are supported on the track D as the boxes pass over it.

Having: now described our invention, what tances to the chain and having wheels run- I ning on the tracks aforesaid, conveyor-boxes secured at one end to each of said axles and adapted to rest on adjacent conveyor-boxes in passing over track D, a propelling device to actuate the chain, a supplemental track running substantially paralleland at some distance away from the incline C of track 0 and substantially merging into said track at the top and bottom of the incline, and a device secured to the free ends of the conveyerboxes, whereby said ends are carried on the supplemental guide or track as the chain passes over the incline 0', all substantially as specified, and so as to maintain the boxes practically level in going up the incline.

2. In combination with a track 0, having a steep incline O in it, and a track D, situated above track 0, an endless chain running over both of said tracks, axles secured at equal distance to the chain and having wheels running on the tracks aforesaid, conveyer-boxes secured at one end to each of said axles and adapted to rest on adjacent conveyer-boxes in passing over track 0, a propelling device to actuate the chain, a hinged bottom g in each conveyer-box, a spring-catch g for holding the bottom closed, trips I) b for unlatching and latching the spring-catch at proper points, a supplemental track running substantially parallel and at some distance away from the incline C of track 0 and substantially merging into said guide at the top and bottom of the incline, and a device secured to the free ends ofv the conveyor-boxes, whereby said ends are carried on the supplemental track-as the chain passes over the incline O,

maintain the boxes practically level in going up the incline.

.all substantially as specified, and so as to v 3. In combination with a trackC, having a steep incline C in it, a' track D, situated above track 0, a supplemental guide E, situated beneath the track 0 and converging toward it at the top and bottom of the incline C, an endless chain passing over tracks 0 and D and having axles secured to it at equal distances, wheels secured on said axles so as to run on the tracks 0 and D, conveyorboxes secured at their back upper ends to the axles of the endless chain, wheels secured to the front lower ends of the conveyor-boxes, so as to run on the supplemental track or guide E, and mechanism for driving the endless chain.

4. In combination with a track 0, having a steep incline O in it, a track D, situated above track 0, a supplemental track E, situto it and converging toward it at the top and bottom of the incline C, an endless chain passing over tracks 0 and D and having axles secured to it at equal distances, wheels secured on said axles so as to run on the tracks C and D, conveyer-boxes secured at their back upper ends to the axles of the endless chain, wheels secured to the front lower ends of the
