AUTGHATIC DUMPING-ELEVATOR.

Specification of Letters Patent.

Patented Nov. 16, 1909.

Application Bled September 15, 1008. Serial No. 453,071.

To all 'whom 'it may concern:

Be it known that I, Gnomi: E. BicluloND, citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Automatic Dumping- Elevators. of which the following is a specification.

My invention relates to new and useful improvements in elevators and more particularly to that class of elevators which unload utomatically.

The object of the invention is to provide a device of this character which will automatically unload anything that has been placed in it for elevation to a. stated place.

Another object of the invention is to rovide mechanism whereby the load carrie by the elevator may be automatically unloaded from the same mechanism at different heights by means of a tri ping device which can be adjusted on the iiame work to any desired height.

A further feature resides in the arrangement of a shifting mechanism so that when either elevator reaches the height the elevators will be made to reverse their directions.

Finally the object of the invention is to provide a device of the character described that will be strong, durable, eilicient, easily constructed and comparatively inexpensive to produce and one which will take up e small amount of room and in which the parts will not be likely to get out of working.;` order.

With the above and other objects in view m invention has particular relation to certam novel features of construction and operation an example of which is given in this specification and illustrated iu the accompanying drawings, wherein:

Figure 1 is a side elevation of my device. Fig. 2 is a front elevation of the same showing the shifting mechanism.

Referring more particularly to thc drawings the numeral 1 designates a foundation upon which my device is built. Upon this foundation u right. supports t! rest. 'lhcse supports arc icld in proper :elution to curh other by inca ns of close-beams 3; elevators 4 operato between suid supports.

5 designates tho curs which nro )lx-otvrl to tho elevators nl; U und arc normal y held ul ou upright position by coil s )rings 'c' ut tho top thereof which are of .sul icicut. strength to hold the cars in an upright position even when carrying a great weight.

On the front of one of the elevators 4 is a collar 8 throu h which operating cord 9 slides. This co lar is provided with a spring for the purpose of breaking.,r the shock of a sudden sto when the car is elevated to a suiiicent heloht that collar 8 will strike sto 10 immovablly mounted on operating cor 9; which occurs just as the car is deliected forward to a de ec suliicicnt that the contents of said car will be dumped out of same. This movement of the car is caused by its striking a V shaped deflector 11. This defiector is so ositioned, with respect to supports 2 and t. e car 5, that when t e elevator ascends the to of the rear side of the car, carried by sai elevator, comes into contact with the sloping side of the dcliector; and the car brin pivoted to the elevator, at the point 6, an bein yieldably held in an uprwht position t erein by sprin 7, is deflected forward as its rear side s ides up the outwardly divergent side of deflector 11, and its contents thereby discharged.

The numeral 12 designates a pulley wheel upon which cable 13 operates. One end of this cable is attached to one of the cars, and the other end to the other car, and serves to su port said cars. Cord 9 is provided for tie urpose of operating and shifting

drive bets

14 and 15, and operates upon the pulley 16 at the top of su port 2. One end of this cord passes aroun pulley 20 secured to su port :2 ucar its lower end, and also arounc pulley wheel 21, secured to a suitable cross beam, at a point preferably above shifting har 17, and near the end thereof, remotcst from pulley 20, and, after passing around said pu ley Q1 is secured to said shifting har I?, 1n any suitable manuel', so that an upward pull on the end of cord 9 nssiug around pulley Q0 will cause said mr to move in n lateral direct ion. 'lhc other und of said cord El passes around the pulle 23, carried by support 2, ucar its lower en( operates on the intervening pulleys 22 und M and ls secured in any suiluhlo n'muuer, to shifting bnr 17 at a point naar the cud thorool, rmuotcst from pulley E23; so that au upward pull ou this und ol cord il will causo shifting hur I7 to more iu u lutcrul direction the oppositi-` ol that. luovouumt unused hy the upward pull on that end of su'ul oord pussiug around pulley 20, as nhove described.

llil

lVhen the shifting bar 17 moves in the direction first above described, it shifts one drivin belt from the driven pulley 1S to one o the idlers 19 and at the same time shifts the otliei` driving belt from the other idler to the drive pulley; and when shifting bar 17 moves in the other direction the drive belts are shifted back to their original position, and as drive belt 11i is crossed, it

'ves a motion to drive pulley 18, which 1s lie reverse of that imparted by drive belt 15, which is not crossed, and consequently each time the drive belts are shifted the movement of the elevators is reversed. This shifting bar 17 is rovided with lugs 31 for engaging with sai' belts and causing them to move with said bar, as liereinatter set forth.

25 is a shaft carrying idlers 19 and drive pulley 18 and also gear wheel 26. This gear wheel 2G operates gear wheel 2T which in turn operates shaft .28 which carries it. This shaft also carries operating pulley 29. A cable 30 operates on palle 29 and being attached at its ends to tlic ottom of each of the elevators transmits motion to each of them.

The o eration of m device is as follows: When t e machinery 1s running at will the

drive belts

14 and 15 run upon the icllers 19 and the elevators are thus at rest, but when it is desired to operate the elevator the operator may throw one of the belts to the drive pulley 18 and thus set the elevators in motion. The shift bar carries lugs 31 which force the belts back and forth 1n accordance with the motion of the shifting bar. When the elevators are put in motion one car will ascend and the other car being attached to the saine cable will descend at the same time and the saaie distance. The collar 8 comin in contact with stop 10 forces cord 9 up2 w ich being attached to shift bar 17 gives it a lateral motion and shifts the drive belts from the drive pulley and one idler to drive pulley and the other idler as above described. Near the lower end of this cord and stationary thereon, is a stop 32 also provided with a spring for the saine purpose as the slpi'ing carried by collar S efore nienlioncf. lVhen the descending elevator comes in contact with stop 2X2 the coi'd 9 is pulled in opposite direction, and shift bar 1T again shifts the bolts and the motion of the elevators is again reversed. This operating cord passes through cach of these springs and while thc one carried by the cord remains stationary thc one rarried by tho car moves freely upon the operating cord.

When the elevator rises lo llio desired height thc car strikes the V shaped adjustable dcllrctol.' 1l and is lillrd forward to auch a. degree that tho controls carried hy the cai' will lie caused to fall oat. ',lliia doflcctor is provided with lugs or clamps 33, extending laterally from each end of the transverse brace of dellcctor 11. These clamps embrace supports 2 and are secured to said supports by means of pins 34, which pass through said clamps and through holes 35, in supports 2. A number of said holes 35 are provided to permit the vertical ad- 'iistment of the delector 11 on supports 2. Vhen the car reaches this height the springs carried by the elevator will strike stop l0 upon the operating cord and cause the direction of the elevators to be immediately reversed and when the car reaches a certain position in the opposite direction the elevator will strike stop 32 located on the operating cord, again causing reversal of the elevators as above described.

While this articular form is shown I do not desire to iiiiit myself to this particular construction. The construction may e varied in any manner so that the priiic le of the invention is not departed from.

Special attention is called to the method of pivotall holding car in osition in the elevator a so to the adjustable method of tilting the car so that the contents thereof will be automatically unloaded.
