CONVEYER-SYSTEl CONTROL.

Application le. April 5, 1920.

To all whom. t may concern.'

Be it known that I, Err-IAN N. Hnscook, a citizen of the United States, residing in l/Vestiield, in the county of Union and State of New Jersey, have invented certain new and useful improvements in Conveyor-System Controls, of `which the following is a specification.

This invention relates to over-head con veyer systems having electric motor driven hoisting devices thereon, and has for one object to provide means for supplying electric current to the motor without the use of sliding contacts.

lAnother object of the invention is to provide convenient means for controlling the movement back and forth of the trolley of the conveyor.

Other objects of the invention will appear as the description proceeds; and while herein minute details of the invention are described, the invention is not limited to these, since many and various changes may be made without departing from the scope of the invention as claimed.

In the accompanying drawing, showing by way of example, one of many possible embodiments of the invention,

Figure 'l is a side elevation showing the conveyer system and a row of floor machines from which is derived the operating current for the motor, and to and from which the conveyer may carry material or products; and

Fig. 2 shows a planV system.

of the conveyer My improved conveyer system is shown in combination with a row of separated, electrically driven floor machines, 5, each provided with a socket 6 having its contacts electrically connected to the feed conductors which supply current to the motors of the machines. These machines may be of any kind of electrically driven machines, and while not limited to such as could be conveniently used where an overhead conveyer is needed, will usually be of the kind which require a conveyer system for Adelivering to the machines material to Vbe worked upon or carryingtherefrom a resulting product. However,y while the conveyer system is shown in combination with these machines, the invention is not so limited, since a plurality of contact sockets 6, could be spaced along at convenient intervals mounted on suitable Specification of Letters Patent.

means other than machines, and fed from current other than the feed conductors above mentioned.

The over-head girders 8 of the conveyer system are each suitably supported above or near said machines 5 and are each formed with upper and lower flanges or tracks 9 and 10, between which are received track wheels il, of a trolley 12 on which are mounted hoisting drums l5 driven bv suitable electric .motors 17 each provided with a flexible conducting cable 18 provided at its free end with a contact plug 19 adapted to be received in the contact socket 6 of` any one of said machines 5 which may be most convenient to the trolley l2 at the time. By this means current is supplied .to the motors, without any current carrying sliding contact which would cause dangerous sparking, or without using inconveniently long cables 18.

Around each drum. is wound .a hoisting cable 20, and each motor is provided with a convenient operating switch controlled by a pair of flexible cont-rolled devices 2l, which may be, for instance, chain, rope, .rod or the like, terminating in a ring or other handle.

Means `*will now be described for driving the trolley l2 back and forth upon the tracks. Mounted upon the Aend supports 25 of the girder 8 is a platform 26 supporting a standard 2.7 braced against the sup ort 25 by 'means of a spacing plate 28.v aid standard has rotatably mounted thereon a cable drum 30 connected by means of suitable reducing` gears 3l and 32 toV the shaft 33 of a cable-drive motorv mounted on said platform 26.

v means 46.

'The operation ofzthe apparatus is very simple, When there is an article to be conveyed one of the operating ineans i6 isV the switch ot the cable-drive inotor is put v. to neutrali position. One neaitie oi" the cables 18 is then inserted in the socket 6 most. conveniently located relative to the position ot the trolley. Then one oit the flexible control devices Q1 is pulled; thus srA plying current to the lioistiem inotor to lower the hoisting cable iin'tiA it is loir enough to be attached to the object to be conveyed.` The opposed trolley device 2l is then pulled, supplying` current to the motor for winding' up the cable and raising; the object, whereupon the sivitcli oi1 the hoisting motor is put to the neutral position by the operation of the trolley devices 2l. rllhen the cable plug; lll is .vithdrairn socket G and attached to a lioolr or th upon the trolley, as shown at the l Fig. l. @ne oit the l'leiible opere i, 416 is then pulled supplying` current to cable motor 35 -for incvfr the trolley the conveyed object to the desired loir i When this desired location is reaelie l the plug 19 is again inserted into the conveniently located socket. 6 and' one o? the trolley devices 2l operated to supply curi nt to the hoisting motor for lowering* the conveyed object at the required location.
