Specification of Letters Patent.

Patented Jan. 1, 1918.

Application filed July 22, 1916. Serial No. 110,697.

To all whom it may concern:

Be it known that 1, CHARLES E. RILEY,

a citizen of the United States, residing at Newton, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Apparatus for Distributing Cotton or other Materials, of which the following is a specification.

This invention relates to certain new and useful improvements in apparatus for distributing cotton or other materials and has particular reference to a device applicable to delivery aprons or lattices, such as used in cotton mills, for delivering the material to a plurality of bins or machines.

The invention resides primarily in an improved device of this type which will be automatic in its action in delivering the material at predetermined intervals to any or all of the bins or machines. v

A further aim of the invention is to provide an improved timing mechanism operable, in this instance, from a continuous drive through a friction clutch.

Further, an object of the invention is in the provision of a plurality of deliveryeifecting mechanisms with which a mechanical selector is associable for selectively and automatically effecting the delivery of cotton, or other material, at the various bins.

The invention embodies, further, the features of construction, arrangements and combinations of parts hereinafter described and claimed, reference being had to the accompanying drawings wherein- Figures 1 and 1 disclose, continuously, a machine in side elevation embodying the present invention.

Figs. 2 and 2 represent, continuously, the machine in top plan.

Fig. 8 is a sectional view on line 33 of Fig. 1 showing the delivery-eflfecting mechanism.

Fig. i is a similar view on line 1-4 of Fig. 2 showing the timing disk and the fricton clutch for driving the same,

Fig. 5 is a detailed perspective of a part of the escapement lever, and Fig. 6 is a view showing a plurality of delivery points.

Referring more particularly to the drawings, the numeral 1 designates the usual channel through which the delivery aprons 1' move, said aprons including in the preferred embodiment a p rality Of delivery sections such sections being tiltableabout shafts 2, as in Fig. 6, and which are spaced along the-channel throughout its length for delivering the material to underlying bins. Fixed on each shaft is a lever 3 weighted at one end, to retain normally the delivery section of the apron in horizontal position, and pivotally carrying at its other end an arm at which is designed to be swung into the paths of lugs or catches 5 of a reciprocatory actuator 6. This actuator consists of a series of connected yokes 7 having the oppositely facing lugs 5 projecting inwardly to engage the arm 1, one lug 5 engaging the arm to open the delivery point and the other arm engaging with the arm, on opposite movement of the actuator to close the delivery point. p

The mechanism employed to swing the arm 1' comprises the present invention and will now be described in detail.

Swingingly mounted on the supporting structure or frame '8 is a crank shaft 9 having an axially extending terminal 10 which overlies the yoke '7 and is comparatively long to be disposed alongside of the arm 1 at alltimes. The shaft 9 is further provided with n arm 11 to which one end of a cable or other connection 12 is fixed. After passing over suitable idlers 13 and 14 on the frame. the flexible connection 12 is connected to the respective one of a plurality of levers 15, one lever being provided for and connected with the shaft 9 at each delivery point. For convenience in illustration and forthe sake of clearness, only one connection 12 has been shown leading from the levers. j r

The levers 15 are pivoted between their ends on a fulcrum rod 16 suitably mounted in a frame 17 of the supporting structure 8, one end of each lever bearing a weight 18 and the opposite end being formed with a cam face 19 over which wipes the selecting dog 20. The dog or lug 20 1s slidable on a rotating shaft 21 so that the lug may be selectively positioned to serve as a depressing element for any of the levers. When each lever is depressed, a locking lever or latch moves to hold the lever 15 in this position until the latch, which is loose on a shaft 23, is kicked free of the lever by a positive timing dog 24. A rod 25 is provided to LOO hold the loose, lever-holdinglatches 22 in position relative to the levers 15. The release dog 21 comprises an elongated frame to engage all the loose latches and is fixed to the positive timing shaft 26 which is geared to the shaft 21 by the gears 27 and 28.

The operation of the mechanism thus far described is as follows:

With the bin or machine to which the cotton is to be delivered, determined, the selecting dog 20 is slid along its shaft 21 to lie in the plane of the lever 15 corresponding to the bin previously determined, so that in rotating with the shaft, said dog will wipe the lever and depress the same. This operation effects a pulling on the flexible connection 12 and consequently a swinging of tie crank shaft 9 to move the arm 1 into the path of the proper catch 5 whereby the reciprocating actuator 6 may partially rotate the shaft 2 and open the delivery point.

The continuously rotating shaft 21 will carry the selecting dog 20 from the depressed lever, and were it not for the respective latch 22 dropping or falling into position to lock the lever depressed, the latter would be elevated by the weights 18 and permit of the actuator closing the delivery point. The latch thus holds the lever 15 depressed until the releasing dog 24: engages with and swings the opposite end 22 of the latch, in an obvious manner.

In this connection it will be noted that since the latches 22 retain their respective levers depressed subsequent to the riding off of the selecting dog 20, the latter may be shifted to act upon another lever so that the newly selected delivery point will be opened before the closing of the next previous delivery point.

The means for properly locating the selecting dog 20 is a very important part of this invention and will now be set forth in a clear manner.

As shown in Fig. 2 a fork 30 is slidably mounted in the frame 17 and straddles the selecting dog 20, sliding movement being imparted to the fork 30 by a pitman 31 connecting the fork to the crank portion 32 of a shaft 33 which latter is journaled in suitable bearings 3st of the frame 17. Loose on this shaft is a pulley 35, and connecting this pulley to the supporting shaft is a friction clutch 36. A belt 37 delivers power to the pulley 35 from a drive pulley 38, the latter being supplied with energy from a suitable source through the transmission gearing designated generally by the numeral 39.

Thus, as the shaft 33 rotates, the fork 30 and selecting dog 20 will be reciprocated. If, however, the shaft is intermittently stopped at predetermined intervals. the dog will correspondinglyv be intermittent in its sliding movement and, with the provision of the means new to be referred to, a sulficient pause will be afiorded to permit the dog to efiectively depress the underlying lever 15. I

This controlling means comprises an escapement or timing wheel -10 of disk formation on the outer face of which. are fixed a circular series of predeterminedly spaced pins 41. Any number of such pins may be provided, each being positioned to engage with the pawl or lever 12 to stop the rotation of shaft 33 when theselecting dog is over the respective lever 15. If it is desired not to deliver cotton to one or more bins, the corresponding pins 41 are removed from the wheel 40.

The escapement pawl 4-2 is pivoted at 43 to the frame 17 and has freoor pin-engaging end bent upwardly at right angles to form a wall 44 and thence forwardly and downwardly to constitute an abutment 15. The wall stat is provided adjacent its upper end and in a plane above the depending abutment 4:5 with a cut-out 1-6. This pawl is constantly being oscillated by means of a lever l7 which is pivoted at 18 between its ends'and formed with a fork 419 to embrace the pawl. lever is connected to an eccentric 50 which is rotated by the gear 51, the latter also driving the gears 27 and 28 thereby timing the operation of the associated parts.

As the pawl l2 is lowered, the pin 11 engaging the wall as is permitted to escape through the cut-out which has been brought down in alineinent therewith. The friction clutch 36, which has been slipping while the pin engaged the wall, now becomes effective and rotates the shaft 33 and the wheel 40 until the suceeding pin 41 strikes the abutment or step 4.5 whereuponthe clutch again slips and as the pawl is raised the arrested pin rides off the abutment l5 and moves on under the action of clutch 36 until arrested by the wall 4. lVhile in this arrested position, the selecting dog acts upon the lever over which it is positioned and the subsequent operation, above described, is repeated.

Reciprocating movement is given the actuator 6 by the rotatable gear 52 which carries a. pin 53 operable in the vertical slot 51 of a rigid arm 55 on the actuator.

Brie y recapitulating. the operation is as follows:

The pins 11 having been predeterminedly arranged on disk 10. the respective weighted levers 15 are successively depressed to swing the crank shafts 9 and thereby disposed the arms s for engagement bv the constantly reciprocating actuator 6. hen thus engaged the levers 3 are swung to oscillate the frames 60.

These'frames are mounted to swing about, thQ'fihitifiSig anicarryontheir outer ends;

The opposite end of the the rollers 61 about which the delivery aprons 1 pass. The frames thereby provide tiltable sections for opening the conveyer'to deliver the cotton-to underlying bins not shown. hen the delivery end of the conveyer is tilted 0r deflected the lower flight of the apron is supported by an idler 62, as indicated by dottedlines in Fig. 6. Spring clips 63 engage the free ends of the frames. for retaining them in normal position.

From the foregoing, it will be clear that the action is entirely automatic and that the device may easily be applied to delivery aprons now commonly used.
