Application filed October 2'?, 1919.

T 0 all whom t may concern:

Be it known that I, WILLIAM E. Brsrror, a citizen of the United States, residing at Kansas City, in the county of Wyandotte and` State of Kansas, have invented certain new and useful Improvements in Stamping Machines, of which the following` is a speciication.

My invention relates to a machine for stamping or printing words., symbols, or other distinctive marks on articles of food such as nuts, oranges, lemons, etc., and in its present form embodies a hopper for holding the articles, dies for printing the articles, chutes for directing the articles from the hopper to the dies, means for presenting the articles one by one to the dies to insure the stamping of each article, and means to prevent the articles from clogging between the hopper and the chutes.

In the accompanying drawings which disclose the preferred embodiment of the invention:

Fig. 1 is an end elevation of the machine.

Fig. 2 is a broken plan view of the ma chine.

Fig. 3 is a broken vertical cross section 'taken on line III-III of Fig. 2.

Fig. 4 is a broken horizontal section, enlarged, on line IV-IV of Fig. 7, of the stamping mechanism and associated parts.

Fig. 5 is a detail perspective view of the dies for printing or stamping the articles.

- Fig. 6 is a detail perspective view of a reciprocatory stop to support the articles in position to be stamped or printed.

Fig. 7 is a broken side elevation, partly in section, of the stamping mechanism and associated parts.

Fig. 8 is a horizontal section on line VIII-VIII of Fig. 7.

Fig. 9 is an irregular vertical longitudinal section on line IX-IXvof Fig. 8.

Fig. 10 is a cross section, enlarged, on line X-X of Fig. 7.

Fig. 11 is a fragmentary section of an agitator.

In carrying out the invention, I employ a suitable table 2, consisting in the present instance of a horizontal top 4 and supporting legs 6.

8 designates a hopper in which the articles to be stamped are placed. Said hopper 8 is Acarried above the table 2 on suitable means, such as brackets 10, secured upon two oppositely disposed, inclined supporting peoication of Letters Patent.

The chutes 22 are open at that portion o f their undersides which extend over a reciprocatory agitator 26, which moves forward vand backward to prevent the articles from becoming clogged in the bottoni` of the hopper 8 and at the entrance to the chutes 22. v

Theupper surface of the agitator 26 is cor.- rugated as disclosed more `clearly on Figs. 2 and. 11, to better engage and move the articles to and fro, and slopes in both directions from a central point to cause the articles to roll down the chutes 22. The agitator 26 is mounted on antifriction rollers 28 and ball-bearings 30 arranged to ytraverse rails 32 and ball races 84, respectively, fixed upon the upper portion of the frame 18. vleciprocatorv motion is imparted to the agitator 26 by suitableineans such as an eccentric 36, the rod 38 of which is pivotally connected at its forward end to a bifurcated lug 40, fixed to the adjacent end. of said agitator 26.y The disk of the eccentric 36 is fixedly-mounted upon aL shaft 42 jou-rnaled in bearings' 44 and 46 driven by suitable means, such as a bevel gear 48 intermeshing with a bevel gear 50. The bevel gear 50 is driven from a suitable motor 52 through a train 54. The motor 52 is, preferably, supported in a hanger 56 depending from the underside of the table top 4.

Referring now more particularly to the stamping batteries 24- arranged at the lower ends of the chutes y22 and disclosed more clearly on yFigs-4y to 10, inclusive, each consists of a casing 58 iiXedon vtop of the table 4 and reinforced at its sides with longitudinal plates 60, provided'with upper and lower vslideways 62 and 64, respectively. The slideways 62 support a reciprocatory. stop 66 provided withfa stem68, extending rearwardly through a cross-head 7() slidably mounted in slots 7 2 and 7 4 extending longitudinally of the casing 58 and the plates 60, respectively. An expansion spring 76 is in,- terposed between the rear end of the stop 66 and the cross head 70 to yieldab'ly hold said stop a predetermined distance in advance of said cross-head, which is held en the stein 68 by suitable means such as a transverse pin 78. c

80 designates a second reciprocatory stop provided with a body portion 82 having` lon-- gitudinal grooves 84 to receive the slideways 64 upon which said body portion is reciprocably mounted. The body portion 82 has a pair of internal longitudinal slideways 86 upon which a stamping die 88 is reciprocably mounted, said stampingA die being pro-- vided at its sides with longitudinal grooves 90 to receive the slideways 86.

The reciprocatory stops 66 and 80 are alternately. moved forwardly and bacio wardly through the upper and lower portions, respectively, of a port 92 in one of the brackets 14 leading from the discharge end of the registering chute 22 to an underlying port 94 in the table top 4. Suitable means such as levers 96 are employed te actuate the stops 66 and 80. Said levers 96 are fulcrumed on pivots 98 at opposite sides of the casing 58 and pivotally connected at their upper ends to the cross-head 7 0 by links 100.

The lower ends of the levers 96 are connested to opposite sides of the stop 80 by pin-and-slot connections 102. The sides of the casing 58 and the plates 60, have longi tudinal slots 106 through which the pins 102 l extend.

The die 88 is provided at its forward end with any suitable symbol7 letters, or mark, such for instance as that disclosed at 108 on Fig. 5, and is supplied with inl; from a pad 110, which in turn is supplied from an inl; well 114 threaded into a frame 116 carrying- Ythe pad 110. Access is had to the inl: well. 114 to supply the same with ink, through a longitudinal slotJ 117 in the stop 66 and an opening 118 in the top of the casing 58.

The ink pad frame 116 is mounted upon a pivot 120 extending transversely through the sides of the casing 58 and the plates 60 and provided with a coil spr'ig 122, one end df which is secured to isaidipivot 120 and the other to the frame 116 for the purpose of swinging the same downwardly to the position disclosed on Fig. 9, to inlr the symbol 108 on the face of theV die llllhen the die 88 moves forwardly to stamp an article it pushes the pad 110 and its frame 116 upwardly to the position disclosed on Fig. 7 where it'is held by the upper surV- face .of the body portion 82 of the reciprocatory stop 80 and a pair of arms 124 bearing on top of said stop 80 and. fixed to the pad frame 116.

The rear end of the die 88 is provided with a stem 126 extending loosely through a plate 128 secured to the rea-r end of the body portion 82 of the stop 80. A coil spring 130, embracing the stem 126 and interposedV between` the rear end of the die reciente 88 and the plate 128, yieldably holds the cie a predetermined distance in advance of the plate 128, such distance being determined by pin 184 extending'transversely through the rear end of the pin 126 and bearing against the rear side of the plate 128. i

The stop 80 is actuated by eccentric 186, the rod 188 of which pivotally connected to the rear side of the plate 128.

The eiicentrics 136 are lixedly mounted upon cbafts 140 carried at opposite sides of the a, 2, by brackets 142 and provided. with liredly niounted pulleys 144. driven by belts 148 running around pulleys 150 driven by the train 54.

In practice the hopper 8 is filled with articles to be stamped, after which the motor 52 is started to actuate the working mechanism through the intermedia-cy of their various connections above-described. AS the agb tator 26 moves to and fro it causes the arti-4 cles to pass into the chutes 22 which conduct the articles to the ports 92, each of which is only large enough to admit one article at :i time. Should the stops 66 happeirto be in forward position as the initial articles are about to enter the portg 92, said articles are arrested by said stops 66 until the saine move backwardly, while the stops 80 move 'forwardly to intercept the artic es when they are permitted to enter the ports 92, on the backward movement of the stops 66. As the stops 80 move forwardly to intercept the articles, the dies 88 are carried therewith and on contacting the articles, stamp the same, after which the stops 80 and the dies 88 move backwardly and uncover the ports 94 to permit' the articles to fall therethrough.

As the dies 88 move forwardly to stamp Athe y articles as above described, they swing` the pads 112 upwardly against the action of the springs 122, by which time the stops 80 pass beneath the arms 124 and hold the same and the pads 112 in raised position until the stops 80 and the dies 88 move baclwardly to the position disclosed on |Thus it will be understood that the face or printing end of the dies will be supplied with fresh inlr for each printing operation.

By having the stops 66 and 82 alternately move forwardly as above described, it will he impossible for articles to pass through the ports 92 without being stamped, and owing to the yielding connection afforded by the springs 76 and 1807 said stops are permitted to yield in case articles shouldV become lodged between the forward" ends of said stops and the opposite sides of the ports 92.. thereby avoiding damage either to. the stops or the articles. Owing to the yielding connection between the dies 88 and the stops 801 the forward movement of said dies may be greater or less according to size of the articles to be stamped..

From the foregoing description it is apparent that l have produced a machine of large capacity and embodying the advantages above enumerated, and while I have shown and described the preferred 'form ot my invention, I reserve the right to male such changes in the construction, proportion and arrangement ot parts as properly Jfall' within thespirit and scope of the claims.
