STAMPING MACHINE Filed Feb, l5, 1929 2 Sheets-Sheet 2 INVENTOR Wheene- ATTORNEYS Patented Dec. 10, 1929 UNITED STATES GEORGE W. HEENE, 0F CLEVELND, OHIO STAMPING MACHINE Application led February 13, 1929.

Certain types of stamping machines which are employed to engrave a ring or other emblem on a blank and which also usually mechanically vend the stamped blank to a pur- 5 chaser, include a magazine unit. This magazine contains a supply of blanks 'which are fed to the machine to have the stamping operation performed thereon as the occasion demands.

1o of the machines, the magazine units are removable so that they may be refilled with blanks after they are empty. This propertyI of detachabilityof the magazine unit, is an essential, but has caused some little trouble 15 due to the fact that when a magazine unit after being filled is again put into operative position on the machine, it is not properly fastened into place by the person refilling the magazine. Under such conditions, or under 2o conditions wherein the maga-zine is not properly held in position, d mage to the machine very often takes place.

It is the primary aim of this invention to provide novel instrumentalities for holding the magazine unit of the stamping machine in proper operative position, and which instrumentalities provide for the quick and easy removal and replacement of the maga` zine to and from its operative position.

In attaining the end above noted, l provide the supporting frame of `the machine with projections which are adapted to enter recesses in the base of the magazine unit, and a cam moans which functions toeither positively maintain the engagement of the lugs and recesses aforesaid by ri gidl fholding the base of the magazine against the supporting framework, or which may be operated to release the connection between the base and 4.o supporting frame as previously outlined.

A particular feature of the invention resides in the mounting of the cam means set out in the preceding paragraph in the frameu work of the machine. The supporting means for the cam is so arranged that the magazine may be easily moved into and out of positions wherein the lugs and recesses are in engagement with each other. Moreover, the cam is so mounted and provided with an operating En member, that it is readily available to a perlin the now known. constructions Sera] No. 3t!9,688.

son whois desirous of removing or releasing the magazine unit.

With these and other objects and advantages in view as will in part become apparent and in part be hereinafter described, my invention contains certain combinations, constructions and ar 1anp fnnents of parts as will be hereinafter specified and claimed.

For a full and more complete understand ing` of the invention, reference may be had to the following description nnd accompanying drawings, in which- Figure l is a View in elevation from the side, of that portion of the stamping` machine with which this invention is particularly identified.

Figure 2 is a section taken about on the line 2-2 of Figure l which develops certain portions of the stanuiing machine in section and others in elevation.

Figure 3 is a perspective illustration of the lower portion ofthe magazine unit, bringing out particularly the base portion thereof.

Figure l is a plan view of the supporting framework for the magazine unit, with the latter part removed from the former.

Figure 5 is an enlarged detail perspective showing of the cam means which holds the magazine in place.

i While a preferred specific embodiment of the invention is herein set forth, it is to be understood that l am not to be limited tothe enact constructions illustrated and described, because various n'ioditications of these details may be provided in putting the invention into practice Within the purview of the ap pended claims.

Throughout the various figures of the drawings and following description, like reference characters denote corresponding parts.

First referring` to Figures l and 2, the base of the machine referred to generally by the reference character il. Mounted on the base A is the stamping mechanism which may be described briefly comprising`- dies Rhammer C, hammer operating means D, ejector mechanism E, discharge chute llincluding guide-F1, and a magazine unit G with which are associated the connecting instrumentalities which are referred to generally by the reference character H. l

The magazine unit G comprisesthe` tubular member 1 and the base portion 2, these two parts beingy connected together in any7 preferred manner. The member 1 is provided with openings 3 which serve as sight means when one wants to determine how manymetal blanks are contained in the magazine. Needless to say, the metal blanks which the magazine houses, areof disc-like formation and are superimposed one above the other in the housing. A U-shaped mem ber 4 is adapted to be inserted in openings 5 which extend through the Vlower portion of the magazine G to prevent the blanks from falling out of the latter when the magazine is being positioned. After it is properly put in place in the machine, the member 4; may

be removed so as to permit the blanks to feed into the ejector mechanism E. Y

The ejector mechanismE functions to remove a blank which has been suitably stamped by the dies B and hammer C, and discharge t-he same into the discharge chute F. At the same time the ejector mechanism E functions to take a blank from the magazine and place it in position with respect to the dies B and `hammer C so that the latter may properly operate thereon to stamp the desired insignia Y on the blank.

" the base 2 is placed on supporting frame 6 so that the pins 7 enter the holes 8. The camming instrumentalities which `are now to be described, are then operated so that upward movement ofthe magazine base 2 is prevented and the latter is rigidly clampedvagainst the supporting framework 6. o Y

y The camming instrumentalities comprise a bracket 9 which is rigidly fastened to suitable structure on the machine as by the screws 'shown at -10 and this bracket pivotally carries at its upper end a cam member 11, which cam member is provided with' an operating member 12. It is obvious that when the operating member 12'is availed of to swing the member 11 so that its surface which is closest ven toy the pivotal mounting is disposed down- Wardly, there is a space provided between the cam member 11 and the base 2 and this space I permits of the placing of the base member 2 in position or the removal thereof from the machine. Afterthe magazine unit G is positioned a turning of the cam member by its operating member 12 causes the cam surface of the member 11 to firmly clamp the base 2 against the support-ing framework.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is

l. In a stamping machine of the class dc- Scribed, the combination with a frame member and a magazine, of fastening devices for securing the magazine to the frame member, said fastening devices comprising complemental lugs and recesses adapted to prevent movement in one plane, and means for holding the coinplemental lugs and recesses in engagement.

2. In a stamping machine of the class described, the combination with a frame member and a magazine, of instrumentalities for fastening the magazine to the frame member, said instrumentalities comprising means for preventing movement in one direction, and a cam member for holding the last named means in operative position.

3. In a stamping machine of the class described, the combination with a frame member and a magazine, of mechanism for secure ing the magazine to the frame member, said mechanism including complcmental lugs and recesses for preventing movement in one plane and a cam member for holding said lugs and recesses in engagement.

4. In a stamping machine of the class described, the combination with a frame member, of a magazine having a base portion, recesses in said base portion, complement-al lugs on the frame member adapted slidably to engage said recesses, and further means carried by the frame member for holding said lugs and recesses in engagement.

5. In a stamping machine of the class described, the combination with a frame member, of a magazine having a base member adapted to abut the frame member, means on the frame member and the base member of the magazine for preventing relative sliding action between said members and a cam carried by the frame member, said cam being` rotatable to hold the magazine in abutment with the frame member.

6. In a stamping machine of the class described, the combination with a frame member, of a magazine, complcmental lugs and recesses carried the frame mem er and the magazine, and a pivoted cam member carried by the frame member, said cam member being rotatable to hold the complemental lugs and recesses in engagement.

In testimony whereof I affix my signature.

GEORGE VJ. HEENE.
