` UNITED STATES MAX EMIL' TOBELER, OF DETROIT, MICHIGAN.
REMOVABLE PUNCH.
Application led December 29, 1926. Serial No. 157,820.
The invention relates to a tool chuck and more particularly to the `class of removable punch holders.
The primary object of the invention is the provision of a holder or chuck of this character, wherein the punch will be firmly and securely held fast therein and it can be conveniently and readily removed when the occasion requires. in event that the said punch becomes worn, broken or otherwise damaged rendering it unfit for further service.
Another object of the invention is the -provision of a chuck or holder of this character, wherein the punch or other like tool is automatically locked therein, but can be readily and easily removed with dispatch, the holder or chuck being of novel form.
A further object of the invention is the provision of a chuck or holder of this char acter, which is extremely simple in construeti'on,thorougly reliable and efficient in its purpose, strong, durable, readily and easily accessible for the release of the punch or other tool heldy therein, and inexpensive to manufactureand install. i
With these and lother objects in view, the invention consists in the features of construction, combination and arrangement of parts, as will be hereinafter morel fully described, illustrated in the accompanying drawing and pointed out in the claim hereunto appended.
In the accompanying drawing Figure 1 is a vertical sectional View through the chuck or holder constructed in accordance with the invention showing a punch held fast therein.
' Figure 2 is a`bottom slightly reduced scale'.
Figure 3 is a sectional view on the line 3 3 of Figureil looking in the direction of the arrow.y
Figure 4 is a detailed end view of the wedge element used in the holder or chuck.
Similar reference characters ,indicate correspondin partsl throughout the several he drawing. l
Referring to the drawing in detail A designates a ortion of the piercing or punching mac ine to which the chuck or punch holder is applied, this being in any suitable or desirable manner, the holder or chuck being hereinafter more fully de. scribed.
The chuck or Vpunch holder comprises a circular body 5, although the shape thereof plan view on a can be varied at the option of the maker'. Furthermore the size of the body 5v can 'be varied and the same may be made from any suitable material. Formed centrally in the body 5 is the punch' socket 6 in which is adapted to be removably received the punchl 7, which is latched or locked therein for res. movability in a manner presently described.
Coneentrically arranged relative to the socket 6 in the body 5 is a circular cavity 8, the same at oneI end opening through one face of the body 5, while its opposite end merge into an aperture or passage 9 of consider understood from Figure 1 of the` The plunger "'10 in one side thereof is cut away toy form step wedging surfaces 11 and 12, respectively, and adjacent to the wedging step 11 vis a circular or reduced head 13 whichl confronts the passage or opening 9 for a purpose presently described.
Formed in the wall separating the socket 6 from the cavity 8 is a slot 14 in which is received 'a rollertl, the latter being de signed to play against and be backed up by the 'wedging steps 11 andA 12 of the plunger 10 to coact with a lwedge-shaped notch 16 formed in the punch 7,y this wedge-shaped notch 16 being reversely disposed with re-` spect to the wedging steps 11 and 12 of the plunger 10,I so that when the roller 15 is engaged in said notch 16 and backed up by the plunger 10 it will firmly and securely hold the punch 7 in the socket 6 as is clearly illustrated in Figure 1 of the drawing.
To release the punch 7 from the socket 6 in the chuck or holder 5 it is necessary to insert a pin or other likeimplement through the passage 9 for its engagement with the head 13 of the plunger 10 and by pressure upon said pin the plunger can be retrieved againstl the resistance of the spring Y11, thereby permitting the roller 15 to recede from the notch 16 in the punch 7, whereby the latter will be freed to be extracted from its socket 6 in the chuck or holder 5 as will'be clearly apparent. .l e
The wedge steps 11 and 12 of the plunger 10 when acted upon by the spring 11 will automatically advance the roller 15 throu h the lslot 14 to engage ,in the notch 16 in tie punch 7 to lock the same in the Socket 6 when said punchis inserted in the chuck or holder 5.
The slot 14 is of a size to prevent the roller 15 from Working through the same into the socket, so that said roller in this direction of movement 1s limited.
It is also to be understood that the parts 10, 11 and 15 can be multiplied and concentrically arranged' about the punch socket 6 should it be required.
From the foregoing it is thought that the construction and manner of operation of the chuck or holder 5'Wil1 be clearly understood and therefore a more extended explanation has been omitted.
What is claimed is:
A device of the character described, comprising a body having a tool socket and a cavity at one side thereof opening into the same, a tool removably insertable in the socket and having a Wedge shaped notch, a roller located in the communication between the cavity and socket and engageable in the ,'notcli, and manually displaceable spring tensioned means having stepped Wedge surfaces coacting with the roller for automatically orcing the same into the notch.
In testimony whereof, affix my signature hereto.
