Application May 19, 1939, Serial No. 274,546
This invention relates generally to punches, and particularly to an illuminated punch.
The main object of this invention is to construct a punch provided with a means for illuminating the portion of the obj ect being punched.
The second object is to construct a punch especially adapted for use by police oicers, car conductors and bus operators in punching tags and tickets where accuracy in punching is an important factor.
The third object is to construct a punch of the class described which will be easy to manufacture and which cannot easily be rendered inoperative.
These and other objects are accomplished in the manner set forth in the following specification as illustrated in the accompanying drawing, in which:
Fig. 1 is a side elevation of the device.
Fig. 2 is a plan of the device.
Fig. 3 is a section taken along the line 3-3 in Fig. 1.
Fig. 4 is a section taken along the line 4-4 in Fig. 1.
Fig. 5 is a diagrammatic view showing the electrical circuit.
Fig. 6 is a fragmentary section taken along the line 6 6 in Fig. 2.
Fig. 7 is a fragmentary section taken along the line 'I-l in Fig. 3.
Similar numerals refer to throughout the several views.
Referring in detail to the drawing, there is shown a punch having a pair of elongated jaws I9 and II which are iixed in relation to each other and are separated by the elongated slot I2 into which the ticket or tag is inserted for punching purposes.
Integral with the jaws Il) and II is a handle I3. A punch carrying arm I4 is mounted on the pivotl I5 in the jaw II, said pivot I5 being disposed near the end I6 of the slot I2. The arm I4 is provided with a handle I'I and a punching point I8 which registers with the hole I9 in the jaw I0.
Owing to the length of the jaws I and Il, it is desirable to have the pivot I as far as possible away from the open end of the jaws.
A compression spring 20 is placed between the handles I3 and I'I. 'Ihe handle I3 is provided with an opening 2| to receive an electric battery 22 whose negative side is connected by means of a wire 23 to the center contact of the lamp 24 whose receptacle 25 is secured to the punch arm I4 by means of the screw 26.
similar parts (Cl. 24U- 6.46)
The receptacle 25 is so formed as to permit light to shine in the direction of the arrow 2l onto the portion of the card 28 which is being punched.
I'he handle I'I is provided with an opening 29 which receives a battery 30 which is covered with the insulation 3l. The positive pole 32 of the battery 39 is held out of engagement with the contact 33 by friction between the battery insulation 3I and the wall of the opening 29. The battery 30 is urged toward a circuit closing position, thatl is, when the members 32 and 33 are in engagement with each other, by means of a spring 34 which is attached to the threaded cap 35 which forms a closure for the opening 29.
A leaf spring 3G is mounted within the opening 29 on the inner side of the handle I'I and has attached thereto a headed button 3l by means of a countersunk screw 38. It is desirable to have the end 39 of the button 3l knurled to facilitate the operation of the device.
The spring 36 has its end 40 turned to engage the end of the battery 30 and the button 3l is slidable Within the elongated opening 4I to permit the spring 36 to be moved longitudinally in the opening 29.
It is desirable to provide a notch 42 Within the opening 29 to receive one end of the leaf spring 36 in order to insure against having the spring 34 operate the device in a circuit closing direction when such action is not desired.
It will be noted that the contact 33 of the battery 3l) is connected by means of the wire 43 to the shell 44 of the lamp 24.
As a convenient way of completing the electrical circuit, I have found it d-esirable to form a channel in the arm I4 in which are placed the wires 23 and 43 which are imbedded in the insulating material 45.
The operation of the device is as follows:
When it is desired to use the lamp 24 in connection with the operation of the punch, it is only necessary for the operator to move the button 31 away from the handle end of the punch causing the spring 36 to disengage the notch 42 and causing the contacts 32 and 33 to engage each other thereby closing the circuit to the lamp 24 and causing the light to fall upon the card or ticket 28 at the place where the punching is about to be made thereby greatly facilitating the accurate punching of the tag or ticket.
While I have shown the flashlight mounted on the punch arm I4, it is obvious that it could be mounted on the jaws l0 or Il without departing from the spirit of this invention.
While I have thus illustrated and described my invention, it must be understood that it is not my intention to limit myself to the precise details shown herein but I intend to cover` all such forms and modifications thereof which fall fairly Within the appended claim:
An illuminated punch for use by traic officers consisting of a handled jaw member having an elongated ticket receiving slot formed in one end thereof extending toward its handled end, a pivot disposed on one side of said slot between the ends thereof, the side of said jaw containing said pivot having an enlarged opening at its open end and the opposite jaw having a registering punch opening therein, a handled punch point jaw mounted on said pivot having a punch adapted to pass through said enlarged opening into said punch opening, an electric lamp mounted on said punch and in front of said enlarged opening and dry cells disposed Within the handles of said jaws connected to said lamp and grounded to said jaws whereby the light rays passing through said enlarged opening illuminate a portion of an object to be punched.
