-To all whom 'it may concern: v

Be it known that 1, JAMES T. COWLEY, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Conveying Apparatus, of which the following is a specification. w

My invention relates to improvements iii-that class of conveying apparatus wherein an endless traveling cable is utilized to actuate a car-or carrier traveling '10 upon tracks or guide rails, and is so constructed and combined as to enable a car. or carrier to be loaded at a main or despatching station with several separate loads or consignments, and automatically deliver any of the said loads or consignments independently to any of a series of stations located along the system.

This invention also provides for the automatic return of the empty 'carrier'after deliveringthe lastconsignment.

In the accompanying drawings which illustrate a construction embodying my invention, Figure l is a Fig. 2 is a side elevation of same. Fig. 3 is a side elevation of the carrier. Fig. 4 is an end view in elevation of the carrier. Fig. 5 is an enlarged side elevation of cable-gripping mechanism.

Fig. 6 is an enlarged section ofsmne. Fig. 7 is an end elevation showing door-closing and cable-reversing Like letters of reference refer to like parts throughout file several views.

.' The tracks A are fixed to the supports A which also carry the'longitudinall y mounted rails A, and the standards A and diagonal braces A fixed upon the i said rails A support the tracks A. The hoppers B, C and Bare fixed to the rails A and each hopper is divided into three compartments. The tables B1, C

and D mounted on the supports A are located under the hoppers B C and Drespectively. The endless cable X is mounted on the pulleys X and is driven, by the motor X The carrier E (Fig. 3) carries the shaft G fixed in the extensions E upon which shaft are mounted the flanged wheels E adapted to'travel on the tracks A. The rods E are longitudinally mounted in thebrackets E hung under each side of the'carrier E. The carrier-is divided into three compartments E E and E by the partitions E The bottom of each compartment is-divided into two swinging. doors E and E" which swing on the pivots E i the doors E overlapping the doors E The rods'E prevent the said doors from swinging outward too far and the force of contact therewith is checked by the springs E. The catch F (Figs. 3 & 7) is fixed to the rod F which is pivoted in the bearings F fixed to the under side of the doors E The said catch F engages the latch F holding the swinging doors closed.

, The pin F is fixed to the rod F which is longitudinally movable in the support- F which is fixed to the carrier E. The spring F mounted between the said support F and the pin F holds the rod F in an inward position. The outer end of the rod F is pivoted to the lower end of the bell crank lever F which is pivoted to the extension F on the carrier E. The other end of the bell crank lever F" is pivoted to the rod F The upper or bifurcated end of said rod F is pivoted to the extension G on the notched bar G which is pivoted in the bearings G The spring clutch G is adapted to engage any notch on the bar G, each notch designating a correspondingly numbered hopper. The projecting finger G on the clutch Gr is adapted to engage a trip finger H fixed to the cross bar H. The finger (3 controls the discharging of the contents of the compartment E into any of the nine hoppers. The finger J controls similar mechanism for discharging compartment E and the finger K controls the discharging of compartment E-.

Cross bars H are located over each compartment and fingers H H and H are consecutively staggered thereon to engage any of the fingers G, K or J respectively, designating stations represented by said staggered fingers. The rolls L are journaled. in bearings on each swinging door E and E and are adapted to engage the door-closing cams L which are fixed to the supports A.

The hand lever M (Fig. 5) is pivoted on the bar M and works in the yoke M which is pinned to the said bar M. The spring M mounted on the spindle M" and held 't-hereon by the collar M and the nut M acts upon the extension M of the lever M, which forms an eye through which the spindle M is mounted. The shoulder M into which the lower end of the spindle M is fixed, is pivoted in the yoke M and forms a backing for the extension M of the hand lever M. The rod M is pivoted in the bearings M which are mounted onthe blocks N attached to the car E. The lever N (Fig. 8) is fixed upon the end of the rod M at the side of the car E and carries the Shoe N thereon. The finger N on the lever N is connected with the spring N fastened to the side of the car E and which spring N acts upon the said finger N. The latch S is pinned to the shaft G by the pin S and is held .outward by means of the spring S fastened to the carrier E. The slotted extension M is fixed to the rod M and carries movably mounted therein the pin R fixed to the sliding grip R. The stationary member R carries the'grooved jaw -R- fastened to the upper portion thereof bythecotter pins R and the grooved jaw R fastened to the lower portion thereof by the cotter pins R The grooved jaw R is fixed to the upper portion of the sliding grip R and the grooved jaw R is fixed to the lower portion of the saidrolls I and 'P are mounted upon the side of the car E and support the cable "X centrally between the'jaws R and R and R and R preventingthe-cable from wear a ing when the carrier is idle.

* The operation is as follows: The operator standing at the main or despatching station Z loads the carrier E, filling as-many oi the compartments E, E and E as desired each with a separate consignment for any of the department stations located along the line. The operator then adjusts the clutch G (Fig. 4) which clutch controls the discharging of the contents of the compart in'ent E of the carrier E into the notch representing the department station for which said contents are consigned. The clutch K controlling the discharge of the contents of the compartment}? is then adjusted into the notch on the bar G representing the department station to which said contents of compartment are consigned. The clutchJ controlling the discharge of the contents of compartment E is then adjusted into the notch on the bar GP representing the department .yoke M? being fixed to the bar M causes the slotted extension M fixed to said bar M to force the pin R mounted in the sliding grip R down, causing the grooved jaw R fixed to said sliding grip ii to close the lower portion of the cable X between said grooved jaw R and the grooved jaw R The spring M furnishes the required, tension by the grip upon the cable. The lower portion of the cable traveling in the direction indicated by the arrow impels the car E upon the tracks in the same direction. -If the contents of compartment E are consigned to the department station C the projecting finger H mounted upon the crossbar H directly over said station G engages the clutchG causing the pivoted bar G to partly turn in the bearings G the extension Gr mountedthereon forcing the rod F down and throwing the rod F back against the spring F by means of the bell crank lever F The finger F fixed to the rod F now throws the catch F out of the latch F causing the swinging doors E and E" (Fig. '7) of the compartments E to swing outward in the direction indicated by the dotted lines until they are checked by the buffer spring E hitting against the rods E. contents of said compartment are discharged through the hopper (.7 andout upon the table C directly under said hopper. The car continuing in the same direction, the rolls L mounted upon said doors E and E engage the cams L said rolls ridingupon said cams, the roll on the door E in advance of the roll on the door E until the doors are closed and the catch F engages the latch F holding the said doors closed, the pin F in the meantime, having resumed its normal position by means of the spring F acting thereon after the finger G of the clutch G has passed the trip H. The load in compartment E may be similarly discharged by the clutch K engaging the finger H at the designated station, and the operation repeated, heretofore described. The contents of the compartment E being consigned to department station D, the clutch J engages the trip H The mounted on the bar H over said station, causing the pivoted bar G8 to turn, forcing the rod G downward and releasing the doors E and E of the compartment E by means of the bell crank lever F acting upon the rod G throwing the pin Gr fixed thereto against the catch F ted extension M acting upon the pin it throws the jaw 7 b I R releasing the lower part of the cable X until the up per grooved jaw R grips the upper portion of the cable 'X between said grooved jaw R and thegroo'ved jaw R.

The car E now returns with the upper portion of the cable X in the direction indicated by the arrow until it reaches the main or despatching station. The shoe N on the lever N fixed on the rod M at the side of the car E now engages the cam N forcing the lever N down until the rod M throws the hand lever M upward and the grooved jaw to release the cable and the saidpin R to assume a central position between-the upper and lower portion of the cable. The car E now comes to a standstill and the operation maybe repeated.
