EDGAR B. NICHOLS, OF EOCHESTER, NEW YORK.
Application filed September 27, 1921. Serial No. 503,695.
To (MZ inf/710m vz't may concern:
Be it known that T, EDGAR B. NrcnoLs, a citizen of the United States of America, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Tmprovements in Toys, of which the following is a full, clear, and exact speciiication.
This invention relates to toys, and particularly to a mechanism to be used as a toy for cutting out figures, etc., from sheet material. One object of my invention is to provide a device of this nature which will be simple to operate and cheap to manufacture; another object is to provide a simple clamp for Operating a punch; another object is to provide a platen which will bear against and transfer' force to-the punch without a sliding or scraping action; another objectis to provide a seat on the clainp into which a punch can be easily positioned and firmly held in operative position; another object is to provide a clamp which can readily be assembled; another object is to provide a punch which cooperateswith the clamp; and still another object is to provide a cooperating punch which is formed from a single sheet of metal. To these and other ends the invention consists in certain improvements and combinations of parts as will be fully described in the annexed specification, the novel features being pointed out in the claims at the end of the speciiication.
Tn the drawing, in Which like reference characters denote like parts throughout:
Fig. l is a perspective of atoy constructed in accordance with and illustrating one embodiment of my invention;
Fig. 2 is a perspective view of the Workholding pad removed from the rest of the machine;
Fig. 3 is a side elevation of the main casting comprising the base and yoke;
Fig. 4 is an end elevation of the same casting, cooperating parts beingindicated in dashed, and in dot and dash ines;
Fig. 5 is a perspective of the punch and die;-and
Fig. 6 is a fragmentary side elevation of one end of the lever, showing the clamping cam.
The clamp or press of my toy 'consists of a casting 1 having portions 2-2 and 3 to hold it erect upon a flat surface. A curved bracket fi carries at its outer end 5 a lever 6,
which is pivoted by a pin 7 to the Casting and which is operated by a handle 8, thus lowering the holding pad 9 through the cam surfaces l0-10 which contact with 'the inner side of the bottom face 11 of the pad. The sides 12-12 of this member are slotted at 12/-12/ so that it may move to and from the pin 7 which extends through the slots. The slideways 12'-12' permit of a Swinging as well as a sliding movement so that face 11 always rests flat upon the member it engages. It should be noted here, by withdrawing pin 7 my device can be disassembled, this feature being important in facilitating packing for shipment, etc. The work in assembling is likewise reduced to a minimum.
The Casting l carries an anvil 13 upon Which one end of the punch P rests when in operative position, there being a guideway li-la in the base of bracket 4 for supporting the other end of the punch. By moving the lever 6 in the direction shown by the arrow, Figure 1, it is obvious that the pad 9 is lowered toward the anvil 13, and that by continuing such movement considerable pressure can be brought to bear on the moving part due to the design of the eccentric or cam portion 10 pressing on part' 11. It should be noted that while the cam exerts a rotative or sliding force upon part 11, the holding pad will convey only a downward pressure upon the member beneath it, as the bottom 11 of the pad is flat and it moves only in a vertical direction when in contact with a substantially flat surface. The sliding action of the cam is entirely taken up by the pad surface 11 and is not transferred by it to the surface being clamped. This not only prevents marring and scratching, but materially assists in the smooth working of my device. f i
The Cutter, or the punch of my toy, consists of a male member 20 which cooperates with a female member 21, the latter being cut from one end of a strip 22 of-metal and, after being treated as described in my Patent No. l,4-30,02et, issued Sept. 26, 1922, is fastened to the other end of the metal strip to form the male member. The strip is bent at 23 to form a spring lhinge, and, as is clearly shown in the drawing, this fold does not bring the metal faces 24- 25 adjacent the bend into contact, but provides for a sufiicient separation at the bend to avoid cracking or otherwise weakening the bent portion,
and thereby impairing the spring of the metal. Outwardly flared lips 26 and 27 serve to guide the sheet material into the punch,
and in addition provide a grip for the fingers of an operator, enabling him to open the jaws manually if they should by any chance stick together. But the spring hinge 23 normally holds the jaws in the position shown in Figure 6. A notch 28 is cut in the hinged edge of the punch forming a socket which interlocks with the bracket 4 by sliding into the guideway Mflle. This connection can be quickly and easily made by thrusting the punch between the anvil and pad andI into a position where the notch 28 willengage the guideway lde-li, so that the punch will lie upon the anvil under the work pad. On the under side of the bracket 4 there is a stripping finger 30 which is positioned so that it passes a short distance through the female die each time this part is raised by spring 22. There is an aperture 31 in the work pad through which the finger 30 passes when the pad is raised into its upper position, thus removing the cut-out from the female die.
lVhere a variety of sizes and shapes of cut-outs are provided, as in the case of my present invention, it is possible that in some instances the female die (which l preferably mount on the upper jaw as shown) might present a large opening towards the upper clamping member, as is shown in Figure 5, where the position. of the work pad 9 is illustrated by dashed lines. But with a work pad constructed as above described this is not material. since the pad always engages su'fiicient portions of the female die (as at a-a Figure 5) to press the same down firmly. As the pad 11 is flat and there is merely a downward pressure without a sliding action, satisfactory results can be easily thus obtained.
The operation of my device is as follows: The desired Cutter is selected and inserted into the clamp by first, raising; the lever thereby separating the holding pad from the anvil, and second, thrusting the notch 28 into guideway 14-14-2. thus seatinfr the male die upon the anvil 13. rl'he female die 21 held raised by spring' 23. and the outwardly flared lips 26 and 27 serve as guides to direct a sheet of paper, for instance, into cutting position. rllhe force of the spring is also suflicient to hold the pad 9 in a raised position. By lowerinn' lever G, pad 9 is lowered by cam pressing upon the inside of the iat bottom 11 thus causinp; the punch and die to function. By raisingthe' lever the natural spring of the metal will separate the cuttinp,l parts and the paper, and will raise pad 9 so that the cutter can be easily removed. lt should be noted thaty the upward movement of the female die causes the finger 85 30 to pass through the die, stripping the cuti eeacev out therefrom. The cutter can now be removed if desired, and another snbstituted, as l contemplate supplying a number of different cutters with each outfit.
