MAGNETIC TACK-HAMM ER.

SPECIFICATION forming part of Letters Patent No. 710,615, dated October 7, 1902.

Application filed lune 13, 1902.

To (all 11171/0711, t may cm1/cern:

Be it known that LARTHUR R. RoEEn'rsoN, of Somerville, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Magnetic Tack-Hammers, of which the following is a specification.

This invention relates to devices for facilitating the driving of tacksv or small nails at elevated or otherwise distant points which cannot be readily reached by the hand of the user. The object of the invention is to provide a device of this character which may be utilized to readily drive a tack horizontally into an elevated vertical or somewhat-inclined surface or directly upward into a ceiling or other horizontal overhead surface. The device, however, is not limited tothe driving of tacks or nails in elevated or other locations difhcult of direct access.

The invention consists in the article and the construction thereof, substantially as hereinafter described and claimed.

Of the accompanying drawings, Figure 1 represents in a perspective View one embodiment of the invention. Fig. 2 represents a section lengthwise of the hammer-head and through a portion of the handle. Fig. 3 represents in perspective a method of using the device without the hammer-head, said figure also showing an extended handle.

The same reference characters indicate the same parts in all the figures.

The hammer-head represented at d may be generally of the type shown in Patent No. 352,070 of November 2, 1886, said hammerhead having its pointed end bifurcated and magnetized to form a horseshoe-magnet. This magnetic hammer-head is removably connected with the handle by means of a second magnet b,which at its outer end is formed substantially the same as the pointed portion. of the hammer-head d. This second magnet b is suitably secured, as by means of a pointed extension c, in the end of a handle d. The space ein the magnet b has several f unctions: First, it results in the said magnet being of an elongated horseshoe type; second, it enables the two legs of the magnet to yield for the purpose of applying or removing the hammer-head d, as hereinafter described, and,

Serial No. 111,501.

(No model.)

third, it provides a space for the pins, which will be presently described.

The outer end of the handle is preferably inclosed within a ferrulef, which may be of any ordinary type.

, The outer ends of the two legs ofthe magnet b are slightly flanged outward, as at g, which flanges when the hammer-head d is in place, as shown in Figs. l and 2, project outward or apart from each other over the outer surface of the hammer-head, so as to hold said hammer-head down against the end of the handle d. By pressing the two legs of the magnet b toward each other, as by pinching the flanges g, the hammer-head d may be readily removed from the handle, leaving the device free to be employed for the purpose of driving a tack by means of a direct endwise thrust of the handle. This use for the device is illustrated in Fig. lVhen the device is in this condition, it may be used to drive a tack 15 directly upward into a ceiling or at a distance between two objects which would render the tack-receiving surface inaccessible to the hand of the user or in such a place that would prevent the hammer-head Ct being inserted and operated.

To prevent the hammer-head d from becoming accidentally removed from the second or holding magnet b, any suitable wedge or plug may be driven between the legs of said second magnet l). I have represented at 7L a pin or screw which passes through the side of the hammer-head a near its center and into the space between the legs of the second magnet. This pin 7i serves to hold the legs of the magnet l) spread, so that the anges g will prevent accidental displacement of the hammer-head d; but when said pin h is removed the legs of the magnet b may be forced together, as above described, to enable the hammer-head a to be slipped od.

As an additional means for holding the second magnet hin the handle a pinimay beset permanently through the handle and through the bottom of the space e, as represented in Fig. 2.

It will be readily understood that when the hammer-head d is in the position as shown in Figs. l and 2 the magnetic attraction of the second magnet l) will be exerted to a sufdcient ICO extent through either Wall of the hammerhead d, so that the latter may serve to pick up a tack or ,to enable a tack to be so placed against it that it may be driven by a sidewise or ilatwise blow of the hammer. A

The enlarged portion d of the handle shown in Fig. l may be removed and replaced by one or a number of jointed sections d2, as represented in Fig. 3, the jointed connections of the several parts of the handle being of an ordinary type, such as the screw-threaded one shown at the bottom of Fig. 2. y

1 claiml. A device of the character specified, comprising a handle having a magnet fixed to its outer end, and a magnetic hammer-head removably connected with said fixed magnet.

2. A device ofthe character specified, comprising a handle having a magnet secured thereto, the end of said magnet protruding from and in a line with the axis ofsaid handle.

A device ot' the character specilied, comprising ahandle, and a magnet carried thereby and projecting therefrom, the projecting portion of the magnet being split, and the other end of the magnet being tapered and embedded in said handle.

4. A magnetic tack-hammer comprising a handle, a bifurcated magnet projecting therefrom in the direction of the length of the handle, and a magnetic hammer-head mounted on and removably connected with the projecting end of the first-mentioned magnet.

5. The combination with the handle d,ofthe bifurcated magneti) secured therein and having its projecting ends formed With anges,

nd the magnetic hammer-head a having an opening extending therethrough, the ends of the magnet b which project from the handle extending through the opening of the hammer-head d, substantially as and for the purpose described. v j

In testimony whereof I have affixed my signature in presence of two Witnesses.
