INVENTO? RJ. RILEY WITNESSES TTORNEVS RALPH J. RILEY, 0F LIVERMORE FALLS, MAINE.

SPROCKET-CONVEYER.

Specification of Letters Patent.

Application filed November 2, 1918. Serial No. 260,797.

To all whom it may concern:

Be it known that I, RALPH J. RILEY, a citizen of the United States, and a resident of Livermore Falls, in the county of Androscoggin and State of Maine, have invented a new and Improved Sprocket-Conveyer, of which the following is a full, clear, and exact description.

My invention has for its object to provide a conveyer having a sprocket with an annular channel, having flaring sides for receiving a cable and with openings spaced apart and cut from its periphery inwardly beyond the bed of the annular channel so that buttons secured to a cable may drop into the said openings in the sprocket while the cable will fit snugly in the annular channel. Conveyor blocks are secured to the buttons for moving along a conveyer trough in a well known manner.

Additional objects of the invention will appear in the following specification in which the preferred form of my invention is described.

In the drawings similar reference characters refer to similar parts in all the views, in which- Figure 1 is a plan view illustrating a portion of a conveyer provided with my improvements, v

Fig. 2 is a sectional view on line 2-2 of Fig. 1, and

Fig. 3 is an enlarged sectional view of the sprocket wheel.

By referring to the drawings, it will be seen that the sprocket wheels 10 have an annular channel 11 with flaring sides 12, there being openings 13 spaced apart in the sprocket wheels 10 which extend from their peripheries inwardly beyond the bed 14; of the annular channel 11. The sprocket wheels 10 which may be two or more in number have hubs 15 with bearings 16 journaled on shafts 17 The bed 14: of the annular channel 11 in the sprocket wheels 10 is preferably grooved to allow the cable 18 which may be of wire to work freely without dan er of cutting. The sides 12 are flared to ma e certain that the cable 18 will travel in the said annular channel. The annular channel 11 with its sides 12 at the openings 13 is cut away to permit the buttons 19 to move readily into and out of the said openings 13. These buttons 19 are secured to the cable 18, the conveyer blocks 20 being secured to the buttons 19. The buttons 19 are spaced apart on the cable 18 to fit in the openings 13 as the cable 18 passes from one sprocket wheel 10 to the other.

Guides 21 may be disposed at the sides of the conveyer blocks 20 and they pass with the cable 18 from the top of one sprocket wheel 10 to the top of the other sprocket wheel, and a conveyer trough 22 may be provided through which the conveyer block may travel to move forwardly the material which is to be transferred by the conveyer. A support 21 may be provided for the conveyer blocks 20, this support extending between the guides 21.

Having thus describedv my invention, I claim as new and desire to secure by Letters Patent:

In a conveyer an upper trough having a longitudinal slot between its sides, and a lower trough, a wheel disposed at one end of the troughs, the wheel having a peripheral channel, and openings spaced apart and extending inwardly between the bed of the said channel, a cable disposed around the wheel in its peripheral channel, the cable extending below the slot of the upper trough, and above the lower trough, conveyer blocks disposed against the bottom of the troughs and at the periphery of the wheel, buttons secured to the cable, the transverse blocks at their middle portion being secured to the buttons, the buttons being disposed in, and substantially fitting the openings in the wheel, and being also disposed below the slot in the upper trough, and the front and the rear of the conveyer blocks being disposed between and spaced from the periphery of the wheel at the front and the rear of the said openings.

RALPH J. RILEY.
