Patented Sept. 22, 1931 UNITED STATES PATENT; OFFICE RAY D. STREBY, OF `CANTON, OHIO, ASSIGNOR '10 THE TIMKEN ROLLER. BEARING COMPANY, OF CANTON, OHIO, A CORPORATION OF OHIO AUTOMATIC FEED DEVICE Y Application led December 22, 1928. Serial No. 327,910.

My invention relates to devices for automatically changing articles, such, for instance, as the conical raceway members of tapered roller bearings, from a promiscuous mass to a uniform position for delivery to another machine for further treatment. The invention has for its principal objects to roduce Yan automatic ositioning and fee ing devicev that is simp e, inexpensive, compact and easily operated. The invention consists in the automaticv feed device and in the construction, combinations and arrangements of parts hereinafter described and claimed.

In the accompanying. drawings, which w form part of this specification and wherein like symbols refer to like parts wherever they occur, Y 'Fig lis a planv view of an automaticfeed device embodying my invention; o Fig.` 2 is a side elevation of at the side of the device, the hopper being .shown in vertical section;

Fig. 3 is a vertical section on the line 3-3 in Fig. 2; and I 2;; Fig. 4 isa horizontal cross-section through the discharge chute on the line 4.--4 in Fig 3. The automaticfeed device shown in the accompanying drawings is intended to receive a promiscuous mass of roller bearing cones and'deliver them in a uniform position to a grinding machine (not shown). As shown in the drawings, thecones A are provided at their large` and small ends with annular thrustfribs B. The automatic cone feeding device comprises a hopper 1, in which the cones A are deposited promiscuously, and a suitable base 2 for attaching the device to the grinding machine. J ournaled .in a central vertical bore in an upright bearing 3 at the center of thebase member 2 of the hopper 1 is an upright shaft 4. 4 The shaft 4 isdriven preferably by means of a horizontal shaft 5 j ournaled in ahousing 6 boltedto the bottom of the bascvmember 2. The lower end ofthe shaft 4 extends into the housing 6 and has a worm gear 7 fixed thereto which meshes with a worm 8 on the innerend of the horizontal shaft 5. The outer. end of the horizontaly shaft 5 has a drive pulley 9 journaled thereon the discharge adapted to cooperate with a similar clutch sur ace 10 on a clutch sleeve 11 splined on the shaft 5. By this arrangement the shaft 5 may be connected to and disconnected from the continuously rotating drive pulley 9 by 55 sliding the clutch sleeve 11 along the shaft 5. Fixed to the upper end of the vertical shaft 4 above the bearing 3 therefor is a horizontally disposed circular plate 12 which is rotatably supported on a tapered roller bearo ing 13 mounted in a recess provided therefor in the upper end of the bearing 3. Secured to the upper surface of the circular plate 12 by means of cap screws 15 is an upstanding cone 16, whose apex terminates below the 55 `upper edge of the hopper 1. The cone is disposed concentric with the circular plate or disk 12 and has a base of smaller diameter than the diameter of said plate. Located in the circular plate 12 between the base of the 7o cone 16 and the inner wall of the hopper 1` is a series of annularly spaced openings 17, each of which is shaped to permit a cone A to pass therethrough in one position only. Located directly below the openings 17 in 75 the rotary disk or plate 12 is an annular cone ,receiving recess 18, whose outer wall is formed by the wall of the hopper and whose inner wall is formed by an upstanding annular rib 19 formed integral with the base mem- 30 ber 2 of the hopper. The bottom of the annular recess 18 is formed by means of an annular plate or trackway 20 provided at its inner margin with depending flanges 21 thatI are bolted or otherwise rigidly secured to the outer face of the upstanding annular rib 19 on the base member 2 of the hopper 1. The annular recess 18 is concentric with the rotary plate 12vand has sufficient width and depth to accommodate the cones deposited therein. As shown in the drawings, the shape of the openings 17 in the plate 12 is such that the cones that drop therethrough are disposed in the annular recess 18 with their axes disposed radially with respect to the centerof theplate and with their small ends facing outwardly. Secured to the underside of the rotary plate 12, adjacent to the rear. edge of each of the article receiving openings 17 therein, is a pin 22, which projects down- 100 wardly into the annular recess 18 located below said openings and serves to push or drive the c'ones A along the trackway 2O of said annular recess. The pins 22 also serve to hold the cones A immediately beneath the openings 17, thereby preventing other cones from dropping through said openings until the space therebeneath is empty.

The bottom or trackway 20 of the annular recess 18 is provided with a. discharge opening 23, which registers with the-upper end of the downwardly extending discharge chute or slideway 24. The discharge opening 23 in the trackway 20 is of the same size and shape as the openings 17 in the rotary plate 12 located thereabove; and the discharge chute has its side walls undercut to form longitudinal grooves 24a which co operate with the annular ribs B at the large ends of the cones and thus serve to retain the I cones in said slideway. Secured to the inner side wall of theho per 1 above the plate 12 is an inverted V-s aped turning block 25, whose oppositely inclined faces 26 terminate at their lower ends adjacent to the upper surface of said rotary plate.

With this arrangement of turning block, cones that lodge in the openings 17 in the plate 12 in a position which will not permit them to drop through the openings are carried around in the openings until they strike the inclined face of the turning block 25; whereupon the rotating cone 16 operates to force such incorrectly positioned cones up the inclined surface of the turning block to the peak thereof where they are then turned over upon the rotating cone in position to pass through the first empty opening which they encounter. As shown in the drawings, the rotary cone ma be provided with upstanding pins 27 a apted to engage the incorrectly positioned cones and force them up the inclined surface of the turning block.

The operation of the hereinbefore described automatic cone feeding device is as c follows: The cones A are deposited promiscuousl in the hopper and are carried aroun in said hopper on the rotating cone 16 and plate 12. Duringthis movement the cones that are correctly positioned with reference to the openings 17 in the plate 12 will drop through said o enings into the annular recess located theregelow and be pushed or driven by depending pins 22 on the late 12 around the trackway 20 to the discharge opening 23 in the bottom thereof. Upon reaching said dischar opening, such cones fall throu h said openings into the discharge chute or s ideway 24 in the desired position. In the event that spaces beneath the openings 17 are occupied b cones, and in case'the discharge chute is lled with cones, the cones in the annular recess 18 will continue to roll around in said recess over the uppermost cone in the discharge. chute. Cones that lodge in the openings 17 but are not in a position to drop therethrough are carried in said openings to the turning block 25, and, upon engagement with the inclined surface thereof, are lifted out pf the openings and carried up the inclined surface of the turning block until they reach the peak thereof and are thrown inwardly onto the rotating cone. The shape of the peak of the turning block is such that it operates to deposit the cone upon the rotating cone in position which will permit it to drop through the first empty opening it encounters. The turning block is provided with two inclined surfaces so that it will operate to turn`the cones regardless of the direction of rotation of the is designed particularly for feedingeand positionmg cones for tapered roller arings; but the device can be used for feeding other articles whose end portions are shaped differently by shaping the openings 17 so that such articles will pass through said openings only when they are properly positioned with reference thereto.
