1 Cla im. (01. 8515)' This invention relates to glaziers points, viz., an improved quick driving glaziers point.

One object of this invention is to provide a glaziers point that can be very quickly driven into a window sash in any appropriate and desired location on a window-pane without the necessity of previously placing it by hand in such desired location.

Another object is to provide an improved form of glaziers point that can be very quickly and easily removed when preparing to remove a broken pane and replace it with a new pane.

Another object is to provide an improved glaziers point with a medially disposed stiffening ridge that resists deflection when being driven into an unusually hard part of the sash, or hard Wood of which the sash may be composed.

Another object is to provide said stiffening ridge with a serrated summit that virtually saws its way through wood-grain and when being driven, and which increases its stability when it has been driven into the sash.

Other objects and important features are pointed out or implied in the following details of description, in connection with the accompanying drawings in which:

Fig. 1 is a view showing a portion of a windowsash and pane disposed horizontally as if supported on a table, work-bench or floor; a glaziers point on the pane; and a simple form of tool that I choose to call a glaziers point driver or pull-and-push hammer (not claimed as part of the present invention), positioned for rightward movement so asto jerk the glaziers point into the sash.

Fig. 2 is a view similar to Fig. 1, but showing a smaller part of the push-and-pull hammer whose slottedend is at the position where its movement was stopped by the cross-ridges of the glaziers point abutting against the sash when driving of the glaziers point was completed by asingle jerk of the pull-and-push hammer.

glaziers point seated on a fragment of a pane,

the broken lines being intended to show more clearly the position, end View, of the pull-andpush hammer enlar ed in proportion to the enlar ement of the glaziers point.

Referring to these drawings in detail, in which,

similar reference numerals refer to similar parts in the several views, the invention is explained and described as follows:

This glaziers point is a unit that includes four substantially triangular thin plane elements, I, l.

suitable tool for pushing or pulling the elements 6, 5 and 2; 2 into the driven position shown in Fig. 2, viz., to position where the ridges 3, 3 are substantially against the part of the sash into which the front portion of the unit is driven.

The ridge 4 is preferably rearwardly inclined from the summit of the ridges 3, 3 to substantially the apexes of the elements I, I, so asnot to interfere with properly puttying the window sash and pane; and the main purpose of this ridge is to loosely fit in a slot 1 of a suitable tool 8 that can be either pushed or pulled for driving'the front end portion of the unit into the sash. v

The ridge 5 is cooperative with the ridge 4 for stabilizing the summits of the ridges 3, 3, so the latter may be thinner than if unsupported; but the second and more important function of the rib 5 is to rigidify and stabilize the quite thin elements 2, 2 so they will not become detrimentally bent or deflected by their contact with wood-grain etc. in the surface being entered by the elements 2, 2. This ridge is tapered and inclined forwardly from the ridges 3, 3 substantially to the entering point 6; and its summit is preferably serrated from end to end, as seen at 9, sothat, instead of wedging and tending to split the sash, it saws its way'into the sash while being driven thereinto; and be: sides, the wood-fibers tend to rearrange themselves, thereby entering the serrations and resisting movement of the unit from its driven position.

The tool 8 is preferably of solid iron and/or steel, being preferably somewhat longer than shown, as indicated by a part being broken out in Fig. 1, and having a hand-engaging weighty enlargement 9 by which it may be pulled while its furcations in are against the ridges 3-3 and are straddling the ridge 4; so, if pulled sufliciently quick and far and with sufficient force,

3 the tool 8 acts as a hammer, by its momentum, to drive the unit from the starting position shown in Fig. 1 to the driven position shown in Fig. 2.

In operating with greatest efliciency, the sash S is supported and secured in a substantially horizontal position while the pane P (to be secured) is properly positioned; the improved glaziers points are then placed with their plane lower surfaces on the pane; and as each one of these units is to be used, the'tool 'B'is placed with its bifurcated end straddling the ridge 4, and by swinging the tool to a position substantially at right angles to the surface to be entered by the glaziers point, the latter is placed in the proper starting position which is preferably farther from the enter- -ing place than indicated in .Fig. 1; :then, by

properly jerking the tool longitudinally, it carries the glaziers point with sufficient momentum to drive it at a singl movement to the fully driven position shown in Fig. :2. .In thus .driving the glaziers point, the furcations l prevent the glaziers point from turning rightward or leftward. In other words, the furcations:retain the ridge 9 substantially parallelwith the shaft of the tool 8, so thedirection of applied force is the longitudinal direction'of the ridge 5. 01 course the accuracy of keeping the ridge at right-- angles vto the surface to be entered depends on skill of the user, and-the same is true as to the speed and accuracy with which the tool is menipulated for properly engaging with the respective glaziers points and jerking them into their respective idriven positions, .as in Fig. 2. However, sufiicient skilhmay soon-be acquired by a little careful practice, so one of :these 'glaziers points could be engaged and driven every two seconds after they ,are placedvright-side-upon the horizontally disposed pane.

The construction of one ofthese glaziers points is very specifically described as-follows:

It is arigid unitthatconsists entirely of front and rear pairs of plane thin outer-edge portions and front and rear and laterally projecting ridgeportions, the rear sides of the laterally projecting ridge-portions 3-being substantially vertical so as to form abutments for engagement-andcooperation with a point-driving means, for instance, suchas shown at !8 in Fig.2. The front one 5 of said ridge-portions has its rear end against and united with adjoining endsof said laterally and oppositely extending ridge-portions 3, and this ridge portion 5 is tapered to a sharp entering point .at 6. The front pair of said outer-edge portions 2 haveacuteapexes at .6 that meet and merge with said sharp driving .pointof the ridgeportion ,5, and said ridge portion 5 base longitudinal base adjoining and united with inner edges of said .front pairofplan thin outer edgeportions 2. The .rearoneof saidridge-portions 4 is substantially :alined with said front one of the ridge-portions 5 and has its longitudinal base united withinneredges-of the .rearpair of plane thin outer edge-portions I ,whileits front end is against and united with said adjoining ends of the laterally projecting ridge-portions.

With the form of tool here shown, the glaziers points can be engaged with the opposite faces of the furcations l0 and thereby pushed into the sash, so that all the glaziers points, at all sides of the pane-seat, can be driven without the operator moving around to said sides. However, this form of tool is shown merely to illustrate the advantages of this improved form of glaziers point which latter is the exclusive invention claimed inthis application.

Though 'Ihave described this form of the invention specifically, I have no intention to limit my patent protection to the precise details of construction as illustrated and as described in the foregoing, for the invention is susceptible of numerous changes within the scope of the in ventive ideaszassimplieol and claimed; for instance, the thin angular elements I, I could be eliminated without rendering the invention impractical So could the lements 2, 2 beeliminated.

,My invention is claimed as follows:

In a glaziers ;point,-:a rigid unit that consists entirely -.of front .and :rear pairs of plane thin outer-edge portions and front and rear and laterally projecting ridge-portions, the-rear sides of the laterally projecting ridge-portions bein substantially verticalsoas-to form'abutments for engagement and cooperation-with-a point-driving means, theiront one of said ridge-portions having its rearend against andunitedwith adjoining ends of said laterally :projecting ridge-portions and being tapered .to .a sharp entering point, the front pair'of outer-edgeportions having acuteapexes that meet atand merge with said sharp entering 1 point, .said front one of said ridge-portions having a longitudinal base adjoining and united with inner edgesof said front paiiwof plane thinzouter portions-the rear ions of said ridge-portions being substantially ,alined with .said front one of said ridges-portions and having its longitudinal baseunited'with-the inner edges of said rear pairofaplane thin-edgeeportions While its front endlis against and united withsaid adjoiningends of saidllaterally projecting ridgeportions.
