application filed December 31, that. serial No. aaairr.

ent of the United States No. 1,064,452, dated June 10, 1913.

The invention may be described as an improvement on a form of shuck-feeding mechanism wherein the shucks of a row are successively delivered to a chute through which they are conducted to and positioned in an orderly manner on the shack conveyer of the filling machine, as set out in Letters Patent oi the United States No. 1,388,668, dated August 23, 1921.

My improvement particularly concerns and has for its object to provide sim 1e and efficient means for obviating all liability of the engagement of the edges of the u permost shuck contained in the chute wit the opposing edges of the adjacent shuck of the advancing row from the source of supply; such engagement, if occurring, resulting in the rupturing or buckling of the contiguous ends of the shucks durin the downward passage of the shucks within the chute.

The preferred form of embodiment of my invention will be hereinafter particularly described, and the scope of the invention then be defined in the appended claims.

In the drawings Figure l is a slide elevation of a portion of a box filling machine equipped with shuck feeding mechanism embodying the principle of my invention, only so much of the ma chine being shown as is necessary to illustrate the improvement.

Fig. 2 is a partial plan of the machine.

Fig. 3 is an end elevation of the upper or receiving portion of the shuck feeding chute and its associated mechanism, including the delivery end of the shuck'supplying trough. t is a plan of the mechanism shown in Fig. 5 is a side elevation of the same.

Fig. 6 is a perspective View of the plunger for depressing the shucks within the chute.

Fig. 7 is a perspective view of the dog member, and adjuncts, for controlling the advancement of the shucks from the trough to the chute. 1

Figs. 8 to 11, inclusive, are vertical sections through the chute and the delivery end of the shuok supplying trough, together with the plunger and dog member, showing said plunger and member in succeeding pos1tions which the are caused to occupy in relation to each ot ier and to the shucks contained in the trough and chute.

Referring) to the drawings, designates a horizontal ed or table supported adjacent the delivery portion of a match machine; 21 designates an endless conveyor which is arranged to travel continuousl on the bed and transport a" succession of ox-trays across. the path of the matches being discharged from the match machine, and 22 designates a conveyor which is arranged to travel adjacent to one side of and concurrently with the tray oonveyer and is adapted to transport a succession of box shucks (b) inendwise relation to the filled trays on the tray conveyer.

23 designates a conveyer which is arranged to travel adjacent theother side of the tray conveyer and is adapted to transport a succession of plungers 24 in operative relation to a stationary cam'Way 25 which successively reciprocates said plungers across the path of the tray conveyer in a manner to push the tilled trays progressively into the opposing shucks on the shuck conveyer.

, 26 designates a vertically-disposed chute which is supported at its lower or delivery end by a bracket 27 on the bed. The upper or receiving end of the chute is bolted to a flange or bracket 26' depending from one end of a horizontal trough 28 through which the shucks are fed end to end and delivered successively into the upper end of the chute by suitable feeding mechanism, such, for example, as the conveyer belt 33 paesin along the floor of the trough and about u leys at or adjacent the respective ends of t e trou h.

their outer edges with the apex of the cam. This cam 79 is so' disposed that during the verticalreciprocation of the plunger the cam not only contracts with the opposing plane face but also with the cam portion 77 of the I dog. A spring 81' interposed between the dog and a bracket piece 82 on the plate 74 tends to maintainthe dog at all times in yielding contact with the cam 79.

rectan ular incross-section and is designed When the plunger is in its uppermost poto ice the superposed shucks downward to and through the lower portion 31, the curva' ture, of which portion is such as to direct the sition, after having acted upon and depressed the uppermost shuck previously delivered to the chute, the leading shuck of the shucks consecutively toward and into the row is delivered to the chute through the succeeding links of the conveyer. A curved guard strip .31 secured to thelower end of. the chute overhangs the adjacent links of the shuck conveyer. I y

62 designates a vertlcally reciprocating presses each succeeding shuck as rapidly as it is delivered by the belt 33, each shuck being moved a suflicient distance to permit the entry of the next succeeding shuck to the chute. .The downward movement of the u er shuck similarly depresses the previous y. inserted shucks contained in the chute and advancesthem to and individually through the curved foot of the. chute. The plunger is slidably mounted in vertical guides 66 at one sideof the chute,and is connected by means 'of a link-67 with the wrist of a crank disk 68 on a short shaft 69 having its. bearin in A shaft of the filling machine.

bears a sprocket wheel 71 which 'isoperatively connected with and driven from a (See Fig. 1).

The arts above described, excepting as hereina ter particularly ointed out, are similar in construction an o eration to the like-named parts described 1n Patent No. 1,388,668 aforesaid.

72 designates a depending dog-like member which is pivotally supported at its u per end on a horlzontal stud 73 rojecting rom an upstandingbracket plate 4 aflixed to one side of the chute; the pivot holes 75 in the upper part of the dog being vertically-elongated so as to permit vertical as well as lateral movement of the dog. The location of the dog is such that its lower end depends in close relation to the top of the chute and adjacent to the lateral inlet 76 through which the shucks enter the chute,.such lower end being angulated to provide a rearwardly extending V-cam 77 and a forwardly dependinglip 78. The face of the lun or head 63 ad acent the dog is rovide wit a lateralinlet 76, as seen in Fig. 8. The latter shuck-thereupon assumes within the chute j theinclined position indicated and is temporarily maintained in the position by the and thrust .thereagainst of the op osiaif ,plun er having an overhanging head, shuck of the now. At this juncture t e enters the topof the chute and dc vancement of thejrow of shucks is momentarily'. retarded within the trough and the belt 33 passes idly along the bottom of the 'trou h. Inits upward movement the cm 7 9 o the plunger engages the op osin lower end of the do and thus bodily ifts t e dog above the pat of the leading shuck of the row, thence escaping the cam 77 on such end and sliding against the bod of the dog. In the upward stroke the vertical flanges 79' afford an abutment for the contiguous end ofthe leading shuck, thus not only preventing the cam 79 from entering the 'open end of the shuck and displacing the latter, but also precluding advancement of the shuck until the bottom of the head 63 has moved above-the top of such shuck. The spring 81 holds the dog constantly in frictional contact with the cam 79, thus maintaining the dog in its raised position and permitting the unobstructed passage of the shuck to the chute.

In the initial descent of the plunger, after the delivery of the shuck to the chute as just described, the plunger cam 79 impinges against the opposing surface of the dog cam 77, and thus presses the dog bodily downward in such a manner that the lip 78 thereof bears upon and slightly depresses the elevatedend of the inclined shuck, so as to depend below the adjacent upper edge of the leading shuck in the trough, as seen in Fig. 9.

Asthe plunger continues its descent the cam. 79 thereon co-acts with the dog cam 77 to swing the dog bodily toward the inlet of the chute, the lip 78 thus bearing against the end of the leading shuck and moving it slightly back, as seen in Fig. 10. At the same tlme the plunger bears upon the top of the underlying shuck and proceeds to prem it bodily downward. In the continued descent of the plunger its cam escapes the cam 77 of the dog 72, which dog, with its lip 78, still in engagement with the leading shuck 1L a a v in the trough, swings sli htly rearward and is thus maintained until t e plunger has completed its downward stroke and depressed plunger, the lowermost shuck being discharged from the lowerend of the chute and delivered thence to the conveyer'. This being done, the plunger, together with the dog, is raised, the parts thus resuming the relative positions shown in Fig. 8,

repetition of the shuck feeding and depressing operations above described. By this construction, the shucks contained in the trough are consecutively delivered therefrom to and depressed within the chute, each leading shuck of the row inthe trough being. tempo rarily separated and held back at the inlet to v the chute in an effective manner to prevent its interference with the adjacent shuck in the chute, as above mentioned.

ll preferably provide the inner wall of the chute adjacent to and below the inlet 76, with a depending spring apron 83 which, pressing against the opposing end of the shuck as and when the latter is depressed within the chute by the down stroke of the plunger, serves to prevent upward displacement of said shuck during the upward or return stroke of the plunger, and also to maintain such shuck in position to serve as a support for the neirtincoming shuck.

It is to be understood that my invention is not limited to the specific construction's herein disclosed, as the mechanism may be modified within the principle of the invention and the scope of the appended claims.
