PUNCH-PRESS FOB REMOVING AX AND HAMMER HANDLES.

Application filed December 12, 1917.

certain new and useful Improvements in' Punch-Presses for Removing AX and Hammer Handles, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to devices for removing broken handles from hammer and ax heads, and exchanging handles therein, and particularly to devices of this character in which a press is used for this purpose, said press including a punch engaging the helve of the ax or hammer handle.

The general object of the invention is to provide a very simple and powerful punch press of this character, which is very effective in practice and which is adapted to carry punches of various characters.

A further object is to provide a mechanism of this character with means whereby the ax is held in proper position to permit the punching out of the handle, and which is adapted to be mounted upon a work bench or on any other suitable support of like character.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein Figure 1 is a vertical transverse section of my improved press;

Fig. 2 is a top plan view of the cross bar 15;

Fig. 3 is a section on the line 33 of Fig. 1;

Fig. 4 is a section on the line 1-4 of Fig. 1.

Fig. 5 is an elevation .of one of the punches; and

Fig. 6 is a section on the line 66 of Fig. 5.

Referring to these drawings, it will be seen that the base of my improved press is rectangular in form, and is provided with the side walls 10 and the end walls 11. Preferably this base is cast in one piece with upwardly extending standards 12 and with outwardly projecting perforated lugs 13, which extend outward from all sides of Specification of Letters Yatent.

the base and by which they may be attached to a work bench or table. The upper ends of the standards 12 are reduced to form screw-threaded bolts 14:.

Resting upon the upper ends of the standards 12 is a cross bar 15 having perforations 16 at its ends for the passage of the bolts 14:, these bolts carrying nuts 17 whereby the cross bar is held firmly down upon the standards. The middle portion of the cross bar is thickened and is formed with a central perforation 18 which is screwthreaded for engagement by a screw plunger 19 having a head 20 at its upper end, this .head preferably being perforated for the passage of a cross bar or lever whereby the screw may be rotated.

Operating between the standards 12 is a press head 21 comprising a transversely extendin bar having a width slightly greater than t at of the standards and preferably being about an inch thick. The ends of this press head are cut away as at 22 to receive and have guiding engagement with the standards 12. The middle of the press head 21 is thickened as at 23, this thickened portion being countersunk as at 24 for the reception of a head 25 formed on the lower end of the screw 19. This head 25 has swiveled engagement in the countersink 24 and to this end a plate 26 is provided which rests upon the thickened portion 23 of the press head and is held in place by screws or bolts 27.

The under face of the press head is formed with a screw-threaded socket 28 for the reception of a punch 29, as will be later stated. Disposed about midway of the standards 12 are inwardly extending keys 30, these keys being slightly headed as at 31 so that they can not become detached and these keys are adapted to be driven in so as to extend over the head of the ax or hammer from which the handle is to be forced. Below the slots 32, through which these keys pass, the standards are formed with screwthreaded passages 33 and engaging in these passages are the relatively long set screws 34 having heads 85 whereby they may be turned. These are adapted to engage on each side of the ax head or hammer head and hold the head in proper position while the handle is being punched out. The keys 30 act to resist any upward movement of the ax or hammer when the punch is being withdrawn, said punch fitting the eye in the all or hammer Very snugly and, therefore, be-

ing removable with difiiculty. The punches may be of various shapes and sizes to suit them for the different Work to be done. The punch 29, for instance, is intended for forcing out the handles of hammers and is made of tool steel, by 1" oval in cross section, and approximately 4 long. The upper end of the punch is reduced and screwthreaded to extendinto the passage 28. The punch 294 is of tool steel, 4 long, a thick at its middle and tapering toward the side edges so that it is approximately elliptical in cross section. This is to be used for ax handles and is reduced and threaded at its upper end to engage in the opening 28. Other forms of punch may be used for other purposes, but these two formsillustrate the kind of punches which may be used for detaching hammer heads from their handles and detaching ax headsfrom their handles.

In the practical'use ofthis device, if it be intended to remove the handle from an ax or hammer, the head is disposed upon the upper-edges of the walls 10 and the head is held in proper position and from any lateral movement by the set screws 3%. The keys 30 are then forced inward so as to extend over the metal defining the eye 'of the M; or hammer head. The proper punch, of course, has been disposed on the press head 21 and the press head raised to its fullest extent. Now upon a rotation of the screw 19, the press head is forced downward and the punch forced into the eye of the ax or hammer head forcing the wood out. The set screws, as before stated, hold the air or hammer head in ,place when the punch is being removed. The machine can also be used to hold handles while they'are being trimmed to fit the eye in an ax or hammer by placing the handleon the base and screwing down the punch against the handle in the manner of a vise.

While the device may be made of various sizes, ordinarily the standards will have a height of about 14: and will preferably be i by 4', inside measurement, and the. walls 10 and 11 will be about 1 high. The cross bar 15 will be about 5 long and the press head 4% long. Thescrew19 is preferably made oft tool steel having eight threads to the inch.

Amachine constructed in accordance with m invention has been found particularly e ective in. removing broken handles and replacing. the handles and, furthermore, this machine will save considerable time in removing handles and replacing them as it is often the case that the removal of a broken handle takes from half hour to an hour,

whereas it is only a matter of a few minutes toremove av broken handle with my improved machine.
