JAMES WIALKER SCOTT, OF OSVEGO, NEW YGRK.

CARD-FEEE.

Speciceton of Letters Potent.

Patented Mey 14, 1907.

Application filed Pein-nary 20, 3.996. Serial No. Silf Be it known that I, JAMES WALKER Soo'rr, e citizen oi the United States, residing et Gswego, in the county ol" Oswego end State of New York, have invented e. new end useful Card-Feeder, of which the following is e speciicetion.

This invention relates more particularly to that class of machines commercially known as Brernwell feeders. In this elses of feeders, considerable difficulty hes been exerienced in providing inechenisrn thet will eed all the materiel placed therein end iced the seine evenly to the weighing mechanism. This has led to the eniployinent oi presser plates or mechanism which will meinte-in the stock against the conveyer. While this has to e certain extent accomplished its purpose, it is found that the comb which controls the amount of stock carried oil` by the conveyor, when employed in connection with the presser devices, liefs e tendencqfT to se erste the long end short stock and return t e letter to the hopper or receptacle, moreover, partially stripping the conveyor teeth so ythat the saine deliver uneven quantities to the wei 7hing ineohenisni. of t e conveyor delivering the stock in mixed condition, it is very ept to feed the long stock lirst and nelly the short materiel that hes been combed oil the conveyor, and inrtherrnore, the unequal feeding is objectionable es the weighing mechanism will operate i much better when e continuous equal amount is being fed thereto.

The present invention has :for its objectV the provision of novel end sini le Ineens,

whereby the materiel in its mixe condition, Y

as ceo ht by the conveyer will be evenly delivere from the feeder, and the selection or se eration of the diiierent classes of stock, with the return of the shorter, is entirely avoided.

Another end importent object is to provide simple elerm and stop niechenislns, whereb)T when the stock in the feeder is low, or about exhausted, the operator will be notiiied, end the entire cerding mechanism supplied by the feeder, may be automaticelly stopped if desired.

An embodiment of the invention that is et present considered the preferable one is .shown in the accompanying drawings, where- 1n:-

Figure 1 is en elevation of one side of the machine. Fig. 2 is a similar view of the As a, result, insteadY Yteeth S of tie conveyor.

Siniilsrreferenee numerals designate corresponding perte in ell the figures of the drewings.

The general structure of e well known type of feeder is disclosed, the seine comprising s receptacle preferably in the .forni oi e hopper 6. The iront well of this hopper or receptep cle consists of en upwardly extending endless conveyor 7, having outwardly extendin teeth 8. Journeled in the upper portieri o the receptacle is e rock-shaft 9, end secured to seid rock-shaft between the end wells 10 of the receptacle is e depending presser in the form of e plete 11 that swings with the roeksheft Q, end is movable toward end from the oonveyer. The lower portion of the plate 11 is preferably provided on its front side with forwsrdly extending teeth l2 which teeth are thus dis osed in opposing reletion to the The presser plete is vieldinglgr urged toward the conveyer by Ineens of s weight 13, slidehlg rnoonted as shown at 1 4 upon an erm 15, secured between its ends to one of the projecting ends of the rook-shaft 9, and located exteriorly of the easing Yor receptacle. The forwardly extending portion IGof the erm is arranged to abut Yegeinst a, stop 1'? mounted on the adjacent end well 10, and this stop is so located that the inwardly swinging movement of the presser plete 11 is limited to prevent the teeth thereof coming into contact with the teeth of the conveyer.

Associated with the above-described niechsnisrn, is e. suitable comb. In the present embodiment, n. rock-shaft 18 is journaled in the end wells l() outside of the presser plete 11, and is'provided between said end walls with forwardly extending arms 19 secured thereto, which erins project through slots 20 in the presser plete sndoairry at their inner ends e conib 21 of any suitable structure. This comb thus operstes between the presser pletel end the conveyor and between the n per end lower edges of the former. T e rock-shaft 1S is operated in any suitable manner, es for instance, by ineens of e pitrnen 22 pivoted to e, crank erin 23, secured to one end of the shaft, the pitrnsn being IOO IIO

also connected to a pulley t driven through thc medium ol' a belt 25 lirom oiuI oll tlul conveyor shal'ts, as 26.

llie operation olI the mechanism may be brielly described as liollows. The stoel( is placed in the receptacle in the ordinary manner, and when said receptacle .is full, the presser will be in its rcarniost positioii,asin dirated in dotted lines. The weight 13, however, serves to yieldingly urge the plate toward the conveyor, and as the material in the receptacle or hopper is carried away by the conveyor, the presser plate vwill swing toward said conveyor. The comb 2]V is continually oscillatcd between the plate and the conveyor, and is consequently combing oll' the surplus material from the latter. Instead ol this material being returned, over or by the presser plate, back on the top of the body of stock iii the hopper, it is retained by thi` presser, so that it will be immediately reengagcd by the teeth of the conveyer, and thus thc conveyor teeth will at all times be kept i ull and an even quantity be carried aavay to the weighing mechanism. Experience has demonstratcd that as a result of this arrangement there is p actically .no selection or separation between the long and short material, and both are maintained in their mixed con-A dition and lcd evenly to the usual weighing mechanism, whether the hopper is tilled or not.

For the purpose of notifying the operator or attendant when the stock becomes exhausted or is low, the lollowing mechanism preferably fciiiployed. A bell 27 is provided that may be placed in any position desired, and an electrical circuit shown diagrammatically at 2S includes said bell, a source of electrical energy 2.1), and a switch or circuit closer 30. The switch or circuit closer comprises a supporting body 31, adjustably mounted on one end of the wall 10 of the body by means of a screw 32 that is passed through a slot 33 in the support. A pair of spaced contact springs 34 are secured, as shown at 35 on one end portion of the body, and have their free terminals disposed contiguous to each other, but out of contact. To these spring coiitacts 34 the wires of the circuit 28 are connected. An actuating plunger 36 is slidably mounted on the body, and has one end movable between and into engagement with the contact springs, the other end of the plunger being connected to a link 37 having a pivotal connection with a crank arni 38 carried by the rock-shaft 9. It will thus be apparent that when the presser plate 11 swings to its innermost position, the arm 38 will be swung in a corresponding direction, the plunger 36 will be forced between the contact springs 34, and consequently the circuit will be closed, thereby ringing the bell 27 and notifying the attendant or operator of the condition of the machine. If desired suiti l l l l l l l l l l l l able electrically operated stop mechanism, shown diagraillniatically at 3E), may be included in the circuit 2S, and this mechanism may be so arranged that when the circuit is closed, the entire rarding mechanism associatcd with the l'eeder can be stopped.` Any well known or desired type ol' stop mechanism may be employed, as desired, and it is therefore believed to be unnecessary to de* scribe the saine in detail.

From the foregoing, it is thought that the construction, operation, and many advantages ol vthe herein described invention will Je app-arent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion, and ininoi details of construction may be resorted to without departing from thc spirit or sacrificing any ol the advantages ol' the invention.
