vPatented Mar. 24, 1931 nnrr CHARLES J'. FANCHER .AND JOI-IN E51. FANCHER, OF "WINDSOR, VERMONT, ASSIGNORS, g BY MESNE ASSIGNMENTS, TO XVOODVJARD, IUBBARD CO1VIPANY, OF Iii-ILL, NEW HAMPSHIRE, A. CORPORATION OF NEW HAMPSHIRE i eLAzInRs-ronvm DRIVER Application filed June .22,

Our invention relates to improvements in portable hand-operated devices cr machines for driving glaziers points into window sashes, picture frames, and the like, for the purpose of holding or assisting in holding in place the panes of glass in said sashes, frames, etc., which machines comprise magazines for the points and spring-pressed plungers for forcing the points into the wcod surrounding the glass.

One object of our invention is to produce a comparatively simple and inexpensive, but strong, durable, convenient, practical, and easily operated driver for glaziers points, wherein the plunger normally is in retracted position. Heretofore the plunger normal y is in advanced position and is retracted and released by means of trigger mechanism, such mechanism is entirely done away with in the present driver. Y

Another object is to provide simple yet secure means for attaching the driver plate to and detaching it from the plunger.

A further object is to furnish the driver with improved means for using the same in a t-ilted position, with the front end only on the glass and against the wood, and in a manner to enable the points to be driven in very close to the glass.

The driver consists of few parts which are easily assembled, and in case of excessive wear or breakage can be readily removed and replaced with others.

Other objects and advantages will appear in the course of the following description;

l/Ve attain the objects and secure the advantages of our invention by the mechanism illustrated in the accompanying drawings, in which- '40 Figure 1 is a side elevation of a glaziers point driver which embodies a practical form of our invention; Fig. 2, longitudinal,

. Fig. 11, a side elevation of theparts shown in Fig. 10.

Similar reference characters designate similar parts throughout the several views.

The driver comprises a vertical member 1, herein termed a magazine, and usually made in two side sections riveted together, a support 2 extending rearwardly from said magazine, a spring-pressed plunger 3 mounted on said support and provided with a rearwardly extending and somewhat upwardly inclined handle 5, a driver plate 6 secured to said plunger, a wear plate which wear plate might be omitted, as will hereinafter be eX- plained, and a receiver plate 8.

lliithin the magazine 1 .are front and rear, vertical passages 9 and 10, respectively. rlhe passage 9 opens unrestrictedly through both ends, while the passage 10 may open at the .bottom the full diameter 'of the passage, but

at the top is constricted. The passage 9 is in cross section diamond-shaped and of a size to receive laziers oints such as those re resented at 11 in Fig. 2. v

vOrdinarily glaziers? points are with the aid of adhesive material formed into sticks, in the manner well understood by those skilled in the art, and the passage 9 is adapted to receive such a stick. f

Extending rearwardly from the magazine 1, a short distance above thebottom thereof, is an interiorly screw-threaded lug or prot jection 12 in which the forward end ofthe support 2 is received, said support being eX- ternally screw-threaded to engage the threads in said lugs.' Thus the support 2 is rigidly held in a horizontal position. The back part of the magazine 1 is taller than the front part of the same, and there is a horizontal ledge 13 on each side of said magazine.

.In opposite sides of the magazine l, a short distance above the bottom thereof, are two indentations 14, and said magazine is bored back of said indent-ations to receive a horizontal bolt 15. The wear plate 7 is formed with lateral projections or flanges 16-16, and with upwardly extending side pieces 17 which have inwardly extending projections 18-18 that enter the indentations lll. The side pieces 17 are also perforated to receive the bolt 15, by means of which and a` nut 19 said side-pieces are rigidly attached to the magazine. The plate 7 extends beneath the open bottom end of the passage 10, and opens v directly below the bottom end of the passage 9, the opening in said plate corresponding in size and shape with said last-named lpassage in cross section, and being clearly shown .at 2O in Fig. 2. In other words, the opening in the plate 7 is diamond-shaped and of a size to permit the points 11 to pass through the same. The thickness of the plate 7 is approximately the same as that of a point 11. The flanges 16 form supports and guides for the forward terminal portion of the driver plate 6, which plate is rolled upwardly and inwardly at the sides to form beads 21-21 to receive therein such flanges.

The plate 8 is provided to receive the points y11 as they move down out of the passage 9,

under the influence of a follower 22, through the opening 20 in the wear plate 7, in front of the driver plate 6, and said plate is provided at the sides with beads 23-23 that are adapted to receive within them the beads 21 of the plate 6, and with ears 24-24 which are Vadapted to grasp between them the side pieces 17. The projections 1S in the side pieces 17 are formed by a punching process which leaves indentations to receive projections 2525 punched from or in the ears 24. Struck up from the plate 8 at the front end thereof are two protuberances 26, the height of which equals the thickness of the plate 6. rl'hese protuberances prevent the plateA 3 from tilt-v ing upwardly at the front end and thus closing the discharge opening between the plate 7 and said first-named plate. The front end of the plate 8 may be made concave, as shown at 27 in Fig. 5, and the front-end portion of said plate on the bottom is beveled from the front edge downwardly and rearwardly, as represented at 28.

`When the plate 8 is in place, the front end of the sani-e is located a short distance baclr of the front end of the plate 7.

The plate 8 receives the bottommost point 11 and retains it in position in front of the driver plate 6 ready for the latter to force said point into a window or frame member. `llithout the receiver plate the points 11 would escape proniiscuously and prematurely from the magazine.

In the center of the front-end portion of the driver Vplate 6 is a V-shaped notch 29 that corresponds in size and shape approximately with one-half of a point 11, and in said portion on each side of said notch is a recess 30. Obviousl if the plate 6 be forced forwardly, it carries with it the point 11 which is in front of the same. EachA recess 30 is in line with one of the protuberances 26, and thus enable the plate 6 to make its full stroke without encountering said protuberances.

rllhe follower 22 is an inverted U-shaped member which forces the points 11 through the opening 20 in the plate 7 onto the plate 8. One leg of the follower 22 is in the passage 9 and the other leg in the passage l0 and at the bottom of the follower leg which is in the passage 10 is a collar 31, and interposed between said collar and an inwardly extending part at the top of said passage is a spring 32. The spring 32 tends constantly to force the follower 22 downwardly, and cause one leg 1l in the passage 9, follow downwardly with said points as their number decreases, and cause them to be presented consecutively to the driver plate 6.

llhen it is desired to load the magazine with points, the exposed, upper portion of the follower 22 is grasped and said follower elevated against the resiliency of the spring 32 until the leg in the passage 9 is raised out of said passage, swung on the other leg, and permitted to descend with said firstnamed leg on the ledge 13 on one or the other side of said magazine. Then a new stick of points is placed in the passage 9, and the follower 22 is returned to its former position, with the free leg in the passage 9 on top of said points.

The plunger 3 adjacent to the forward end thereof has a downwardly extending leg 33 at the bottom of which is a horizontal foot 34. rlhe side edges of the foot 3a are curved to correspond with the flanges 16, and also to lit within the beads 21 of the driver plate G. rllhe rear end of the foot 34 at the bottoni extends downwardly to form a stop 35 for the plate 6. The plate 6 is held against endwise movement by the stop 35 and a protuberance 36 struck up from said plate near therear end and received in an indentation in the bottom of the foot 34. There is an opening 37 in the plate 6 for vard of the foot 34 for the insertion of an implement used to force said plate into place against the s top 35, and to detach said plate when occasion requires, the beads 21 being sufficiently resilient to enable the to said foot and detached therefrom. Vhen the plate 6 is in place with the rear end against the stop 35, said plate isV prevented from moving kendwise independently of the foot 34, consequently said plate is carried with the plunger 3 in its forward and rearward movements, the plate then sliding between the plates plate thus to be secured 7 and 8. Normally the plate 6 is re- ,85 thereof to bear on the points i tained with its front end in position to engage the bottommost point V11.

lVithin the plunger 3 is a chamber 52 open at the front end to receive the support 2, and having in the rear end a central opening 37 in line with the axis of the support 2. Tn the support 2 is a chamber 33 having at the rear end a flange 39. A bolt 40 has at the front end a head 4l which is located in the chamber forward of the flange 39, and said bolt extends through said flange and the chamber 52, and has a screw-threaded part 42'that extends through the opening 37 to receive a nut 43 behind the end of the plunger 3. The screw-threaded part 42 is smaller in diameterthan the main portion of the bolt 4() to form a shoulder which bears against the front side of t ie rear end of the plunger 3, consequently, when the nut 43 is tightened, said end is tightly grasped between said -shoulder and said nut, and said bolt is thereby held securely in place. ln the chamber 38 is a spring 44 interposed between the inner end of the opening in the lug 12 and the bolt head 41.

Vhen the plunger 3 isv forced forwardly, the bolt 40 moves with said plunger and compresses the spring 44, and, when the force behind said plunger is removed, said spring expands and causes said bolt and with it the plunger to move rearwardly, assuming that the front end of the driver be held against a support which prevents the magazine 1 from moving rearwardly. The plunger`3 in moving forwardly comes into Contact with the lug 12 which limits such movement. The rearward movement of the plunger 3 is limited by the bolt head 41 when said head comes into contact with the support ange 39. During the forward and rearward movements of the plunger 3, said plunger slides on the support 2 and the bolt 40 slides in the flange 39.

.The handle 5 is provided at the rea-r end with a knob 45 to be received in the palm, and

' forward of said knob with upper and under horns 46 to be grasped between the lingers, of the hand with which the driver is operated. The knob 45 the horns 46 aEord adequate and convenient means for grasping the handle 5 and operating the driver.

The magazine 1, the driver plate 6 in part, the wear plate 7, the receiver plate 8 in part, and the follower 22 are generally similarto corresponding members in application for Letters Patent of the United States, filed December 29, 1926, Serial No. 157,656.

1n operating the driver the handle 5 is grasped in the hand, said driver is placed at an incline on`a pane of glass, with the front end or nose of the wear plate 7 against the sash or frame member into which the points are to be driven, and said handle is forced forwardly with a quick movement to carry the plunger 3 against the lug 12 and the driver plate 6 beneath the open end of the magazine passage 9. This movement is against the resistance of the spring 44, and sufficiently forceful and of sufficient length to drive the point 1l, which is on the plate 8 in the path of the plate 6, into the wood to the required depth. `|rllhen the plunger 3 is permitted to be retracted by the spring 44, and the driver is moved to the right or left the required distance and again operated toforce in the second point 11, and'so ony until the work of securing the pane of glass'with the points is completed. i Each time the plunger 3 and the plate 6 are retracted, a point 11 descends through the opening 20 onto the plate 8.

The recess 27 and the beveled part 28, at the forward terminal of the receiver plate 8, permit the front end of a point 11 on said plate to be located very close to the glass when thel driver is positionedready to discharge said point, and to be driven into the wood in actual contact with the edge of said glass. In the absence of some provision of this kind, the total'thickness of the plate 8 would intervene between the point 11 about to be driven and the glass, and said point could not be driven close enough to said glass to secure the same in place to the best advantage, or with a suicient degree of tightness.

The wear plate 7 might be omitted, as shown in Figs. 8 and 9, in which event the driver plate 6 operates,v directly in contact with the bottom of the magazine l, and' is guided and supported atthe forward terminal by the plate 8 and its beads 23.

In place of the receiver plate 8, a receiver plate 47 may be employed, which latter plate has'a slightly convex front edge, that corresponds generally with the preferred form of the front edge'of the wear plate 7, and Yis beveled cleary across from said first-named edge downwardly and rearwardly, as represented at 48-43-see Figs. 6 and 7.

A receiver plate 49 is illustrated in Figs. 8 and 9, which is straight across at the front end, but set back some distance from the front edge of the bottom of the magazine 1, there being no wear plate in this example. Thereceiver plate 49 might just as well be used in conjunction with a wear plate, in which event it would fall short of or beset back from the front edge of the wear plate. With this receiver plate it is possible to locate the forward end of a point close to and drive the same in contact with the edge of the glass, as

with the beveled receiver plate. v y

ln the last two views a receiver plate 50 is shown which has its front edge-locatedsome distance back from the .front edge of the wear plate 7, and the front-edge portion on the bottom beveled downwardly and rearwardly from said edge, as at 51. Thus the receiver plate 50 combines the features of the receiver plates 47 and 49.Vv g

It is now seen that, in each and every one of these receiver plates, provision is made' for 'icm driving the points in very close to or in contact with the glass, a procedure which is very essential, not to say absolutely necessary, if the glass is to be held in place with the required degrees of security and tightness.

All of the receiver plates are provided with the beads 21, ears 24, projections 25, and protuberances 26. Y

More or less change in the shape, size, construction, and arrangement of some or all of the parts of this driver, in addition to those hereinbefore specifically pointed out, may be made without departing from the spirit of our invention, or exceeding the scope of what is claimed.l
