STAMPING-MACHINE.

Specification of Letters Patent.

Patented May 4, 1920.

Application filed June 21, 1919. Serial No. 305,839.

Toall whom it may concern Be it known that I, FREDERICK B. VVIscH- HUsnN, a citizen of the United States, resid ing at Houston, in the county of Harris and State of Texas, have invented certain pew and useful Improvements in Stampingdvlachines, of which the following is a specification.

This invention relates to new and useful improvements in a stamping machine.

One object of the invention is to provlde a device of the character described which has been specially designed for the purpose of stamping nuts, particularly walnuts. In marketing nuts, it is customary for the seller to stamp each nut with a particular trademark or design, and this is a tedious and laborious undertaking when the nuts are stamped by hand singly. The machine herein described has accordingly been designed for the purpose of accurately and rapidly stamping the nuts automatically and in quantities.

Another object of the invention is to provide a machine of the character described, whereby the nuts may be rapidly stamped, with any desired mark or design and without breaking the shell of or injuring the nuts stamped.

A further feature of the invention resides in the provision of a machine of the character described which may be readily adjusted so as to stamp nuts of-any size, or other similar objects.

Vith the above and other objects in view, the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein:

Figure 1, is an end view of the device.

Fig. 2, is a rear view, and

Fig. 3, is a plan view thereof.

Referring now more particularly to the drawings wherein like numerals of reference designate similar parts in each of the figures, the numeral 1, refers to a suitable framework, having the end legs 2, 2. Located between these legs, there is a drum 3, which is fixed upon the transverse shaft 1, one end of which has the relatively large spur gear wheel 5, fixed thereon. The drum 3 has the peripheral recesses 6, said recesses being arranged in lengthwise rows, the recesses of each row, as well as the rows, being spaced a uniform distance apart. There is an arm 7 whose lower end has a bearing on the outer end of the shaft 1, and whose upper end is anchored to the framework, and mounted upon this arm are the spur gears 8 and 9, which are in mesh with each other, and the former of which is in mesh with and drives the spur gear wheel 5, while the latter of which is in mesh with and is driven by the, spur gear wheel 10. This last mentioned spur gear wheel is fixed upon one end of the transverse shaft 11, which is rotatably mounted insuitable bearings carried by the framework, and fixed upon said last mentioned shaft, there is the printing roller 12, whose periphery is preferably formed of rubber or other-suitable composition, and is designed to receive the type 13, of the marks or designsito be printed on the nuts or other objects, said type registering with the recesses 6 of'the drum 3, as the same rotates. ltotatabl-y mounted in suitable bearings carried by the framework, there is the shaft 1%, one end of which has the drive pulley 15, fixed thereon, and provided to receive a belt through which rotation is imparted toit through a suitable motor. shaft also has a small sprocket wheel 16, fixed thereon, which is in alinement with a corresponding sprocket wheel 17, fixed upon the end of the shaft 11 opposite the spur gear 10, and a sprocket chain 18 operates over these sprocket wheels and transmits rotation from the former to the latter.

The numeral 19 refers to distributer which declines from the fixed hopper 20 and which is provided to receive the nuts 21 therefrom. This distributer is suspended by means of links 22, 22, the lower ends of which are This pivoted to the framework and the upper ends of which are pivoted to the sides of said distributer. The distributer is formed with chutes 23, arranged parallel and provided to receive the nuts from the hopper 20, and convey them to the drum 3, and deliver them singly into the corresponding recesses 6 as the drum rotates. The sides of each chute are provided with short ribs 24, the ribs of one side of each chute being arranged in staggered relation, relative to those on the other side and said ribs diverge from the center of the chute toward the drum. l/Vhile any shaped nut or object may be stamped by a machine of this character, the particular design shown is adapted for use in stamping walnuts which are in the form of a prolate spheroid, and as said nuts travel down the chutes, the side ribs, or prosponding side of the distributer, and to the other end of which, one end of the shift rod 26 is pivoted. The other end of this rod is connected eccentrically to the corresponding end of the shaft 14, and as said shaft rotates, said rod 26 is reciprocated, and this reciprocating motion is transmitted through the bell crank 25, to the distributer 19, causing the same to oscillate which results in the downward movement of the nuts along the chutes thereof, and into the recesses of the drum 3.

Rotation is imparted from the drive pulley 15 to the shaft 14, and thence through the sprocket chain 18 to the shaft 11, and the printing roller 12 fixed thereon. Rotation is also imparted from said shaft 11 through the train of spur gears described to the shaft 4, and the recessed drum 3 carried thereby. As the shaft 14 rotates, it operates through the rod 26 to oscillate the distributer 19 through the mechanisms described, and the nuts are thereby fed along the chutes of said distributer and deposited in the recesses, of the drum 3, and the type on said printing roller are arranged to reglster with said nuts and to print the desired mark or design thereon. An inking device 27 of any well known type is employed for supplying ink to said printing roller, and the bearings of the shaft 11 are adjustable, as shown, so that the printing roller may be adjusted toward and from the drum 3, so

that in case the sizes of the nuts vary, the I printing roller may be adjusted accordingly, so that it will contact with the surfaces thereof.

Fixed on the shaft 14: there is a cylindrical, rotatable brush 28 which engages with the nuts when they reach the lower ends of the chutes 23 and assists in seating them firmly in the recesses 6.

Whatl claim is:

1. A device of the character described including a rotatable drum,whose periphery is provided with recesses adapted to receive obj ects, a printing roller mounted for rotation adjacent said drum, means for rotating the drum and printing roller, a distributer provided with delivery chutes along which said objects may be delivered to the corresponding recesses of the drum,lateral ribs carried by the respective chutes, said meansbeing operatively connected with the distributer and oscillating the same to effect the delivery of said objects along said chutes to the recesses of said drum.

2. A device of the character'described, including a drum, whose periphery is pro vided with circular rows of recesses adapted to receive objects, a printing roller mounted for rotation adjacent said drum, means for rotating. the drum and printing roller, and an oscillating distributer provided with sep arate chutes for delivering objects to the recesses of the rows which are carried by said drum between it and said printing roller.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

FREDERICK B. WISCI-IHUSEN.
