HAND-PUNCH.

Specification of Letters Patent.

Patented Sept. 27, 1921.

Application led February 23, 1921. Serial No. 447,123.

To all whom it may concern:

Be it knownthat I, EARL C. GREEN, a citizen of the United States, residing at Spokane, in Spokane county, and State of Whshin ton, have invented certain new and useful lgmprovements in Hand-Punches, of which the following is a, specification.

My present invention relates to improvements in hand punches of the pivoted handle, plier, type involving a pair of turret l punches carrying a series of male dies and combined with a complementary pair of ro tary disks or anvils having female dies corresponding to the punches of the cutting turrets.

The primary object of the invention is the provision of a device of this character by means of which dates, letters, figures, and other symbols may be punched or perforated in sheets, preferably of paper, as for 1nstance checks or receipts for prevention of fraud or for records. The device is simple in construction and facile in operation, and is comparatively inexpensive in cost of production.

The invention involves certain-novel combinations and arrangements of operating mechanism in connection with the plurality of turrets and synchronously movable disks forming the male and female members of the dies, as will be hereinafter more fully set forth and claimed.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention employing two pairs of complementary rotary members in which the parts are combined and arranged according to the best mode I have thus far devised for the practical appication of the principles of my invention.

any changes could be made in the illustrated construction and Amany apparently different embodiments of this invention could be made without departing from the scope'thereof, and it is intended that all matter contained in the following description or shown in the accompanying drawingsis illustrative, and not in a limiting sense. It is also to be understood that the language used in the appended claims is intended to cover all of the generic and specific Vfeatures of the invention herein described,

and all statements of the scope. of the invention, which, as a. matter of language might be said to fall therebetween.

Figure 1 is a side view of a hand punch embodying my invention.` F1g. 2 is\an enlarged, longitudinal sectlonal view throu hthe head of the device, showing one punc turret and a complementary disk, therefor.

Fig. 3 is a View showing a turret and disk and a turret and disk in section, disclosin the means for receiving and disposing o the cuttings from the punch.

As before stated the device is of the pivoted handle plier type, and comprises a pair of crossed handles 1 and 2, pivoted at 3, and normally separated by the spring 3 suitably vembraced within the handles and normally tending to force them apart. The operating mechanism` is manipulated by drawing the two handles together in well known manner.

The respective handles are provided with jaws 4 and 5 and the j aw 4; is fashioned with a housing 6 for the pair of axially alined turrets 7 and 8. These turrets are preferably circular disks of metal that are revoluble on their common shaft 9 which is supported in the housing 6, and one of the turrets, as 8, is provided with an extended hub or bushing 10, projected through the housing and equlpped with an exterior nut l1 for secur- 'ing the turrets in operative position. In

Fig. 3 it will be seen that the shaft and turrets are retained, at one end by a screw 12 threaded into the end of the shaft, and4 at the other end by a hand wheel 13 on the shaft, outside the housing.

The two turrets 7 and 8 bear on their respective peripheries a series of male dies as 14, which may be numbers arranged in rotation, or letters, or other symbols as desired, and each turret is held against reverse or backward movement on its shaft by means of a spring pawl l5, one of which engages a rack disk 16 or 17 on the adjoining faces of the respective turrets 7 and 8. The spring pawls l5 are each attached at the inner face of the housing 6 as shown in Fig. 2 and prevent reverse or backward movement of the turrets, on their shaft 9.

The complementary, rotary anvils 18 and 19 are' hollow disks,` disposed in operative relation to their respective turrets 7 and 8, and are each provided with a series of female dies or openings 20 in their peripheries that register with the male dies of the respective turrets 7 and 8, and are complementary and the operating mechanism thereto. The rotary anvils are supported in the bifurcated jaw 5 on the hollow axle 21 in suitable bearings, and reverse orbackwardrotary movement of the anvils is prevented by means of spring pawls 22 attached at the inner faces of the bifurcated jaw and engaging rack teeth 23 24 in the peripheries of the respective anvils.

The complementary turrets and anvils are operated or revolved synchronously, the turrets to rotate or revolve clock-wise and the anvils to turn anti-clockwise through the turning of the hand wheel 13, for properly adjusting the male and female [dies for unching or perforating a sheet of paper. f or adjusting these parts I provide in the housing 6 a cross arm 25 pivoted at 26 therein, and equipped with a pair of pivoted pawls 27 and 28, the former in the housing to engage rack teeth 29 on the turret 7, and the latter located between the forks of the bifurcated jaw 5 to engage teeth 30 on the anvil 18. The turret 8 and anvil 19 are also provided withyrack teeth as 31 and 32 for co-action with a pair of pivotal pawls and cross arm`A (not shown) but duplicates of the members 25, 27 and 28 on the shaft or pivotal bar 26.

The pawls 27 and 28 are pivoted at 33 and 34 on the` cross arm 25, and springs 35 hold the pawls in contact with the rack teeth of the turret and anvil, a stop 36 in the form of a pin in the housing being provided to restrain the spring pawl 27 as shown.

A main spring 37 is interposed between one wall of the housing and the cross arm 25 to hold the arm in operative position and return to normal position after the dies of the punch have been adjusted.

Thus it will be apparent that the turrets are held in adjusted position by their pawls 27 and detents 15 and the anvils are retained by their pawls 28 and detents 22, after the rotary members have been initially adjusted with their complementary series of male and female dies in register. Should it be desired to turn the turrets and anvils for a selected character, as for instance the symbol 0 the knurled wheel 13 is revolved to revolve the turret 7 bringing this character to position shown in Fig. 3. The rotation of the turret 7, through the rack teeth 29 and pawl 27 causes the cross arm 25 to rock or oscillate to the right in Fig. 2, and the movement of the rock arm 25 or cross arm causes the pawl 28 which engages rack teeth 30, to move to the left in Fig. 2, and revolve the anvil 18 the same distance as the movement of the turret, thus bringing the female die O into registration with the punch or male die 0, A sheet of paper is now slipped in between the jaws of the punch and between the turret and the anvil, and the handles 1 and 2 are brought together causing the male die to pass through the sheet of paper and into the female die, perforating or punching the paper with the symbol 0 or other symbol that may be selected.

The above described action applies to the pair of turrets and pair of anvils, and it will be understood that the turret 8 and Aanvil 19 may be adjusted by manipulation of the nut 11 in Fig. 3 for bringing into register the selected male and female dies, the action being the same as that of the turret 7 and anvil 18.

The springs interposed between co-acting parts and between operating parts provide for a facile manipula-tion and return action of the parts, and assist in holding the different members in normal position. The cutting or piece of paper punched from the sheet falls within the hollow anvil, and, passing through openings as 39 in the hollow axle 21, may be disposed of through the open end or ends of this axle as seen in Fig.. 3, thus preventing the accumulation of small pieces of paper or cuttings.

From the above description taken in connection with my drawings it will be evident that a device that is facile in manipulation is provided to operate accurately and eficiently, and in which a single set of members or a pair of members or sets may be used as desired, and their adjustment accomplished with convenience and despatch.

Having thus fully described my invention, what l claim as new and desire to secure by Letters Patent is 1. The combination in a punch comprising pivoted jaws and a complementary turret and anvil rotatably supported therein, male and female dies on said turret and anvil, detents engaging said turret and anvil, and means carried by one jaw for synchronously moving said turret and anvil to cause registration of selected dies.

2. The combination with pivoted handles and jaws thereon, of a. rotatable turret and rotatable anvil having respectively male and female dies thereon, rack wheels on said rotatable members and detents co-acting therewith, a rock bar supported in one jaw, rack wheels on said turret and anvil, and spring pressed pawls on said bar co-acting with said rack wheels.

3. The combination in a punch as described of a turret-die and a hollow anvil-die and pivoted jaws rotatably supporting said dies, said anvil die having a hollow supporting axle communicating with the interior of the die and adapted to receive cuttings from the female dies of said anvil.

4. The combination with pivoted handles and jaws thereon one of which is formed as a housing, of a turret revolubly supported in said housing and having a series of male dies on its periphery, a hollow shaft supported in the other jaw, and a hollow anvil on said shaft communicating therewith and provided with a complementary series of female dies opening through the periphery of said anvil, for-the purpose described.

5. The combination with pivoted handles and a jaw formed as a housing, of a turret revolubly supported in said housing and having a series of male dies on its periphery, a second jaw and a hollow shaft supported therein, a hollow anvil on said shaft having a complementary series of female dies extending through its periphery, means Jfor detaining said dies, and means for actuating said turret and anvil for bringing selected dies into register, as described.

In testimony whereof I aiix my signature.

EARL C. GREEN.
