SIG-K035 TO THE TEXAS COMPANY, OF NEW-YORK, N; Y., A CORPORATION OF Application filed November 28, 1919. fierlal It'd 341,143.

Be it known that we, GRADY E. FAIRoLoTH and WILLIAM M. MOSELEY, both citizens of the United States, and both residents of Port Arthur, county of Jefierson, and State of Texas, have invented certain new and useful Improvements in Portable Attachments for Conveyers, of which the following is a specification. 7

Our invention relates to conveyers and other apparatus for manipulating cases and packages and has special reference to means for taking cases or packages from storage tiers and delivering them to a continuously operating conveyer.

One object of our invention is tovprovide a relatively simple and effective conveyer attachment that shall be readily portable from one location to another and particularly adapted for carrying boxes or cases from the to of tall stacks in a storaJ-ge warehouse, and elivering them at reg ar predetermined intervals to a continuously operating conveyer.

In order that our invention may be thoroughly understood, we will now proceed to describe th same in the following specification, and will'then point out the novel features thereof in appended claims.

' Referring to the drawings:

Figure 1 is a side elevation of a conveyer attachment arranged and constructed in accordance with our invention and constituting an embodiment thereof.

Figure 2 is a plan view of the same apparatus.

Figure 3 is a partially sectional elevation corresponding to Figure 1.

Figure 4 is a partially sectional plan view corresponding to Figure 2.

Figure 5 is a partially sectional elevation illustrating the portability of the apparatus.

The structure illustrated comprises a frame 10 which is supported for transportation on wheels 11 and 12 but may be supported on the wheels 11 and on jack screws 13 when the device is operating in a fixed position.

The frame 10 is triangular in side elevation and supports an inclined, laterally movable chute 14. In addition the frame sup ports a pair of oppositely extending 90 degree roller avlty chutes 15 and 16 which are arrange to deliver packages and boxes to the top of the chute 14, the latter being adjusted in pos1t1on to cooperate with either the one or the other of the gravity chutes. In Figure 2 the laterally adjustable chute 14 is shown cooperating with the 90 degree roller gravity chute 15. I

- The ad ustment of the chute 14 is effected by means of a pair of spaced adjusting screws 17 and 18 which are interconnected by sprocket wheels 19 and chain 20 or by other suitable gearing so that they operate concurrently when the crank or other suitable lever 21 is attached to either of them and operated.

The chute 14 comprises a frame structure 22 on WhlCh are supported a plurality of shafts 23, 24, 25, 26 and 27. A sprocket wheel 28 is secured to the shaft 23, and cooperates with the driving sprocket 29 in supporting an endless chain or belt 30, towhich lugs 31 are secured. A gear wheel 32 is also secured to shaft 24 and meshes with the gear wheel 33 on shaft 25. The chute 14 further comprises a conveyer belt or chain 34, having a plurality of spaced lugs 35 thereon, which extends over and is driven by a sprocket wheel 36 on shaft 25. The belt or chain 34 also cooperates with idler sprockets 37 on shaft 26, and 38 on shaft 27. The shaft 27 is adjustable in response to takeup screws 39 and the shaft 23 is adjustable in response to takeup screws 40, thus the chains or belts 30 and 34 are maintained taut.

Mounted on the shaft 26 is a brake drum 41 with which cooperates a brake band 42, the arrangement being such as to preclude too great a freedom of movement of the chain 34. When the apparatus is supported by the wheels 11 and 12 as shown in Figure 5, wheel frames 43 are fastened in .a fixed position to the frame 10 by means of pins 44 and the machine may be guided and drawn about by workmen by means of handles 45 pivotally attached to wheel forks 46. The wheels 11 are mounted in the forks Q raoa ee 46 which are sup-ported in bearing brackets 47 on the frame and are free to turn to constitute steering wheels.

The operation of the apparatus is as follows:

Assuming that the machine is wheeled to a position over a travelling apron conve er 48.,havin upwardly extending lugs or flig ts 49, which position is adjacent to the tiers or stacks of boxes or cases which are to be transferred to the conveyer. When the apparatus is so located, the jack screws 13 are screwed downwardly by means of cranks 50 so as to take the weight of the frame from the wheels 12 and permit the pins 44 to be removed. The frame is then lowered by turning the screws in the reverse direction until the projections 31 of the chain 30 come into the range of and are drlven by the flights or lugs 49 of the apron conveyer.

Assuming that the apron conveyer 1s moving in the direction of the arrow 51, the result is that the chain 30 is actuated and drives the sprocket 29. This in turn drives the gears 32 and 33, the sprocket 36 and causes the chain or link belt 34' to travel in the direction of the arrow 52.

Cases or boxes which are to be lowered to the main conveyer 48 are fed into the machine at the upper end of gravity chute 15 from which they enter the top of the auxiliary conveyer or chute 14. The cases or boxes engage the successive lugs 35 and slide down the chute 14 by gravity, their speed, however, being determined by the lugs 35 which travel at a substantlally uniform rate determined by the movement of the main conveyer. i

The boxes or cases are released as each in swings downwardly at the sprocket whee 36. At this point the case or box, such as the case 53 of Figure 3, slides'out of the chute at the lower end and is delivered to the apron conveyer 48. The arrangement of lugs 35 is such that each case is dropped on to the main conveyer between the lugs or flights 49 thereof, and is straightened on the conveyer by flexible arms or fingers 54 which are attached to the bottom of the chute.

If it is more convenient to feed the boxes or cases into the roller gravity chute 16 the chute 14 is adjusted laterally from the osition shown in Figure 2, to a correspond- 1ng position on the opposite side where it is in position to cooperate with the chute 16. The lateral adjustment being accomplished as hereinbefore set forth'by means of screws 17 and 18.

-An apparatus of preferred form and construction has been illustrated and described for the purpose of showing a way in which this invention may be used, but the inventive thought upon which this application is based, is broader than the illustrative embodiment thereof, and we therefore intend no limitations other than those imposed by the appended claims.
