STAMPING DEVICE.

Specification of Letters Patent.

Patented Mar. so, 1920.

Application filed January 12, 1920. Serial No. 351,074.

To all whom it may concern:

Be it known that I, STRAUD W. RENICK, a

' citizen of the United States, and a resident of the town of Britton, county of Oklahoma, and State of Oklahoma, have invented new and useful Improvements in Stamping Devices, of which the following is a spec1fication, reference being had to the drawing accompanying the same. I

This invention relates to a stampmg device, particularly a punch for treating sheetmetal, and especially particularly for stamping numbers. either upon or through the hood of automobiles.

The special object of the invention is to stamp automobile hoods with identification numbers.

The drawing showsa device adapted to accom olish the objects named, Figure 1 being an elevational view thereof, while Fig. 2 is a detail perspective view of one 0]": the dies accompanying the device.

An arbor is formed by arms 3 and joined by a bow 5, and these arms 3 and 4 are of sufficient length to permit sheet metal stock of considerable length to be fed between them, as will be later explained. At the outer end 6 of the upper arm 8 is a bearing 7 through which a plunger 8 is permitted to reciprocate when a blow is dealt upon its head 9, the plunger being held up or sus pended by a spring 10 associated with a stud 11 on the'plunger 8. The lower end of the plunger 8 is bifurcated at 12 to receive an elongated die 13 (see Fig. 2) having openings 1 1 each registering with characters 1-5 on the face 16 of said die and the plunger has an opening through which and these openings 1 a pin 17 is passed when the die is in use.

The lower arm 4 supports an anvil 18 behind which is a bearing 19 having an opening 20 and across this bearing and upon this anvil 18 is laid an elongated die 21. having die characters 22 corresponding to those 15 on the die 13. This elongated die bar 21 also has openings 23 to register with opening 20 so that when a pin is passed through these the die bar is set in place to register with the die on the bar 13. As to the characters of these dies it makes no material diflerence whether or not they form a raised, depressed or perforated character or symbol. When the die bars are properly located, and the sheet metal is between them a blow on the head 9 will form the character, after which the spring 10 will automatically return the plunger to uplift position so that the stock may be removed.

Beneath the arm a and integral therewith is a bifurcated member consisting of tines 24: and 25 for slipping over a plate on workbench or table, when the same can be secured in place by screw 26, in bearing 27.

Having thus described this invention, I claim:

An arbor, a plunger, a spring for suspending the plunger in the arbor, an anvil in the arbor, a bearing at the rear of the anvil, an elongated die carried by the plunger, and adapted to be adjusted therein, an elongated die bar carried upon the anvil and in the bearing and shiftable transverse to the path of movement of the first named die bar, and means for holding each die bar in position for operation.

Signed at Britton, in the county of Oklahoma and State of ()klahoma this 22nd day of December in the year of our Lord, nineteen hundred and nineteen.

STRAUD W. RENICK.
