GLAZIER'S POINT DRIVER Jan. 20, 1959 Filed Nov. 28, 1955 RD 0 mi K m #3 m 4 ITTOIFNEY.

United States atentO "ce GLAZIERS PGINT DRIVER Chester K. Judd, Jr., Bristol, Conn., assignor to The Fletcher-Terry Company, Forestville, Conn., a corporation of Connecticut Application November 28, 1955, Serial No. 549,251 Claims. (Cl. 1-44) This invention relates to a glaziers point driver and more particularly to a hand operated device for dispensing and driving glaziers points into a window sash or the like to hold panes of glass therein.

An object of the present invention is to provide such a device Which is highly efiicient in its operation and which can be economically produced in large quantities.

A further object of this invention is to provide such a device which is easy to use and to refill with points when necessary.

Further objects and advantages of this invention will be more clearly understood from the following description and the accompanying drawings in which:

Fig. 8 is an isometric view of the combined point driver and return spring member.

Fig. 9 is a plan view of the anchoring member.

Fig. 10 is a plan view of the carrier member.

Fig. 11 is a bottom view of said carrier member.

As illustrated in the drawings, my improved device includes a frame 5 which is preferably formed of round wire and includes an upwardly inclined U-shaped handle portion 6 and a base portion 7; the said base portion consisting of a pair of spaced parallel prongs 8-8 which project forwardly from the portion 6.

An anchoring member 9 extends across said prongs and consists of an elongated bar 10 having inverted U- shaped end portions 11-11 which extend over the prongs and are preferably spot welded thereto, as indicated at 12-12, to secure the said anchoring member to the prongs. The bottom surface of said member is substantially on a plane with the bottom surfaces of the prongs, and the central portion thereof is bent upwardly, as at 13, to provide a channel thereunder and has an opening 14 therein. The anchoring member 9 carries a combined point driver and return spring which is constructed of fiat spring stock and includes a driver 15, that is riveted to the underside of the said portion 13, and an inverted U-shaped return spring portion 16, one leg of which extends upwardly through the said opening 14 and the other leg having a free end portion 17 bent forwardly therefrom.

The said anchoring member 9'is disposed rearwardly of the free end portions of the prongs 8-8, and a carrier member 18 extends across said end portions of the prongs. The said carrier member consists of an upper Fatented dart. 2Q, 1859 plate 19 having inverted U-shaped end portions 20-20, in which slidably fit the end portions of the prongs 8-8, and lower plate portions 21-21 which extend inwardly from the U-shaped portions and under the said prongs and the central portion of said upper plate 19, as clearly illustrated in Fig. 2. The central portion of said upper plate is bent upwardly, as at 22, to provide a centrally located passage through the carrier member which is in alignment with the channel that is formed under the upwardly bent portion 13 of the stationary anchoring member 9. As shown in Fig. 11, one of the lower plate portions 21 of the carrier member 18 has an extension 23 which projects into a notch in the opposite plate portion 21 to strengthen the bottom of said carrier member.

The driver 15 is secured against the bottom of the raised portion 13 and extends forwardly therefrom into the said passage 24, as clearly illustrated in Fig. 5. The front portion of the said driver has a V-notch 25 therein to conform with the shape of the glaziers points that are used with said device.

The upwardly bent portion 22 (Fig. 6) of the carrier member has an upwardly extending lip 26 which provides an abutment for anchoring the free end 17 of the return spring portion 16, and the said raised portion also has a hole 27 therein, shaped like the glaziers points, but slightly larger, which is adapted to receive the lower end of a stack of points 28 which are adhered together by a suitable adhesive that is adapted to release only the bottom point from the stack as it is being driven by the device.

The upper plate 19 (Fig. 2) and the lower plates 21- 21 of the carrier member are secured together by a pair of vertical posts 29 29 which extend upwardly from the carrier member 18, at opposite sides of the portion 22, and provide a support for a tubular magazine 30 which has a central portion 31, that conforms to the shape of the points, and tubular side portions 3232 extending therefrom which fit over the said posts 2929 so that the said magazine is slidable thereon and may be removed by raising it off said posts.

In order to force the said stack of points downwardly, I provide an inverted U-shaped spring member 33 having one end thereof preferably anchored upon the anchoring member 9 by a rivet 34. Its opposite end is freely movable and extends downwardly into the magazine 31) andhas a loop 35 at its end which engages the top of the stack of points.

The carrier member 18 has slots 36--36 in its opposite sides which receive projections 37-37 extending from the prongs 8-8 that engage the ends of said slots and slidably retain the said carrier member on the prongs.

In the use and operation of my improved device, the

stack of points 28 is first placed in the tubular magazine 30 so that the bottom of said stack extends into the'hole' 27 and rests upon the bottom of the passage 24, directly in front of the driver 15 and partly within the notch 25 therein. The free end of the spring member 33 is then inserted into the magazine and allowed to press upon the top of the stack of points and the device is ready for use.

When it is desired to drive the said points into a window sash 38, or the like, the device is simply held by the handle 5 and the carrier member 18 is placed on the surface of the glass and against the side of the sash. The handle 5 is then forced towards the sash and this will move the member 9 and driver 15 forwardly relatively to the carrier member 18 causing it to pick up the bottom point in the stack 28 within the notch 25 and force said point forwardly, through the passage 24 and into the sash, as illustrated in Fig. 6. The device is then moved away from the sash and the spring 16 will return it to its normal position shown in Fig. 5.
