MACHINE FOR DRIVING GLAZIERS POINTS.

SPECIFICATION forming part of Letters Patent No. 403,886, dated May 21, 1889. Application filed November 28, 1888- Serial No. 292,078. (No model.)

To all whom it may concern:

Be it known that I, FRANKLIN HOLLAND, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Machines for Driving Glaziers Points, of which the following is a specification.

My invention relates to improvements in machines for driving glaziers points; and the objects of my improvement are to improve the eiiiciency of the machine, to render it more convenient for use, and to render its construction simple and substantial.

In the accompanying drawings, Figure 1 is a side elevation of my machine with the parts in their normal position. Fig. 1 is a radial section of the pawlcarrying arm, together with a side elevation of the pawl and spring. Fig. 2 is a front elevation of said machine. Fig. 3 is a rear elevation of a portion thereof with some of the parts in vertical section on line y y of Fig. 1. Fig. -:i is avertical section thereof on line 00 cc of Fig. 2, the same being illustrated with the operating-lever raised and the hammer drawn back. Fig. 5 is a vertical section of a receptacle provided with three delivery-slots instead of only one. Fig. 6 is a front elevation of the lower portion of the machine, showing an alternative construction. Fig. 7 is Fig. 8 is a reverse plan view of the hammer. Fig. 9 is a central vertical section of the parts shown in Figs. 6 and 7. Fig. 10 is a sectional view corresponding with Fig. 4 of the lower part of the machine, showing a modification of the the driverguard and pawl for holding the hammer-head to the rear, and Fig. 11 is alike view of said pawl and adjacent parts when in their locking position.

A designates the frame of the machine having two feet, of which the foot 10 at the rear is preferably formed of wood, and the foot 11 at the front side is provided with a vertical opening through it, and with suitable guides for the hammer-block 12 and driver 13. In the preferred form the side edges of the driver 13 are rolled over to form grooves, which, in connection with the side ledges on the foot 11, serve to guide the hammer block and driver in their longitudinal movement. The

rear end of the hammer-block 12 is provided with a guide-rod, 14, around which a spiral spring, 15, is arranged to drive the hammerblock forward. This guide-rod is also provided on its upper side with a recess or notch, 16, one end of which forms an abutting shoulder for engagement with the rear end of the lever-pawl 17 for holding the hammer-block back in the position illustrated in Fig. 4. This lever-pawl is depressed at its rear end to engage the notch in the guide-rod by means of a spring, 18, which is secured to the upper side of the foot 10.

Pivoted upon a horizontal shaft, 19, there is a revolving receptacle, C, having two circular flanges, 20 21, separated from each other on their confronting faces by a space which slightly exceeds the thickness of a glazierpoint, and which flanges flare outwardly from each other to form the body of the receptacle, as shown. The space between the confronting faces of the flanges is maintained by the connecting-posts 22 and holding-screws 23, as shown in Fig. 4.

Access is had to the interior of the revolving receptacle by a removable cap, 24, upon the front, the said cap being made to fit the central opening in the front, and provided with spring-arms 25 for holding it in place, said arms being represented by broken lines in Fig. 2. The opening is notched on one side, as shown at 44, Fig. 2, to enable the spring-arm 25 to be inserted in place. Inasmuch as the machine is portable and may sometimes be turned bottom side up, the up per part of the slot or space between the

flanges

20 and 21 may be closed by a horseshoe-shaped piece of metal, 26, the lower ends of which are riveted or otherwise secured to the back side of the chute 27, which chute is secured to the front side of the frame A by means of screws 28. The contour of the interior of the chute and the strip of metal which closes the upper side of the slot in the receptacle is indicated by broken lines in Fig. 2. In the construction shown this horseshoe-shaped piece of metal by being fastened to the stationary chute also serves as the means for holding the receptacle from worktoo ing longitudinally on its axis.

The lower part of the chute is but a little wider than one glaziers point, said points being triangular in shape, as indicated by broken lines, forming a triangle in Fig. 2, the same representing a side view of a glaziers point as caught by the spring 29 within the lower supplying the chute with points for driving in the manner hereinafter described.

B designates a lever pivoted to the frame A, and provided with a downwardly-proj ecting arm, 30, the lower end of which comes in 'front of the hammer-block 12, as shown in Figs. 1 and 4, whereby an upward movement of said lever B will draw the hammer-block backward far enough to allow it to be locked in its rearward position by the lever-pawl 17,

v as shown in Fig. 4:. On the front end of the leverB there is a short arm, 31, to which is pivoted a pitman, 32, the upper end of said pitman being pivoted to the pawl-carrying arm 33, which arm rocks on the shaft 19, and one end of which arm carries a spring-pressed pawl, 34, that engages the ratchet-teeth 35 on the back of the receptacle, whereby a reciprocating movement of the lever B will impart a like movement tothe pawl-carrying arm, and thereby, through the ratchet-teeth and spring-pawl, move the receptacle intermittently.

At the lower end of the chute there is a slide, 36, which closes the same and is pressed rearwardly to withdraw it by the spring 37, Fig.

4, and is moved forward by thedownwardlyprojecting arm 30 of the lever B, when said lever is returned to its normal position by means of the spring 38, thereby letting the inwardly-projecting arm of the spring 29 into the chute, to obstruct the passage of points through the lower end thereof, every time the lever B is raised, and by bearing against the lower end of said spring pushing it outwardly to withdraw said arm when the lever B is in its normal position, in which case the. slide I 36 closes the end of the chute, said arm act- -in the footpiece 11 and hammer-block 12, separately from the movement of the driver.

ing again to stop all of the points, excepting the one lying directly upon said slide, so soon as said slide is again withdrawn.

Within the body of the hammer-block 12 there is a spiral spring, 39, coiled around the shank of the driver-guard 40, said guard being arranged to slide forward and backward This guard is prevented from sliding forwardly, under the influence of the spring 39, beyond a given point by means of the projection 41 on the upper side of the driver 13,

which engages a slot in the under side of said guard. An adj llStlTlg-SCI'BW, 42, is placed in the front side of the foot 11, for the .purpose of regulating the distance that a point after being driven shall project from the gag- .mer-block in its rearward position.

ing-face, as, for instance, the inner face of the sash.

The receptacle being supplied with a number of points the machine is operated by lifting the lever B from the position shown in Fig. 1 into that illustrated in Fig. 4:- This movement of the lever causes a partial revolution of the receptacle, so as to change the position of the points therein and causesome of them to fall down to the lower end of the chute, where they will be stopped by the inwardly-projectin g arm of the spring 29 in case they fall after the lever is lifted, or if one has fallen down before it will be stopped by the slide 36. In case a point is stopped by the slide'36 when the lever is lifted, it will fall downward into the opening in the chute and upon the top of the driver-guard 40. The inwardly-projecting arm of the spring 29 will prevent more than one point from falling at one time either by coming under the edge of the lowest point but one within the chute or by bearing upon its fiat face, in either event preventing other points from falling. The

driver-guard 40, when the hammer-block is in its most forward position, has its front end stopped by contact with the bar across the front side of the foot 11, thereby forcing said guard into the hammer-block while the driver 13 is allowed to come nearly or quite flush with the front side of said foot. When the hammer-block is first drawn backwardly, the spring 39 holds the driver-guard 40 in a stationary position until the projection 41 reaches the limit of its movement in the under side of the driver-guard, after which said guard,

driver, and hammer-block move rearwardly together, and the point which lies upon the top of the driver-guard drops through the opening in the foot ll and lies upon the face of the glass.

In using the machine the feet 10 and 11 rest upon the glass being set, and the adjustingscrew 42 is pressed firmly against the face of the sash into which the points are to be driven. Then the hammer-block 12 and its connected parts have been drawn backwardly into the position shown in Fig. 4, the lever-pawl 17 engages the guide-rod 14 and holds the ham- Upward pressure onthe lever B is then released, and the spring 38 throws it into its normal position, when the arm 30 strikes the slide 36, thereby olosin g the lower end of the chute and pushing the spring 29 forward to withdraw'its arm and let another point fall upon said slide. N

The end of lever B also engages the long end of lever-pawl 17, thereby releasing the hammer-block,which, under the force of the spring 15, moves forward with a rapid stroke. In

the foot 11 when the under side of the foot at said front serves'to hold the point down, the driver-guard yielding as the driver 13 continues on to or nearly to the front edge of the foot, as shown in Fig. 1. The distance that the adjusting-screw 42 projects beyond the front of the driver when in this position regulates the length of projection of the base of the driven point. By turning this screw out or in, this projection can be regulated from almost nothing up to any desired extent.

In the alternative form (shown in Figs. (3 to 9, inclusive) the grooves for guiding the hammer-block are formed in the foot 11, instead of in the edge of the driver; but this differ- V ence alone is not a substantial one and not the main difference between this alternative device and that first described. The principal difference resides in the fact that the driver and driver-guard have a fixed relation to each other, instead of having separate movements, and therefore the driver cannot well be made to come soclosely to the front of the machine. The driver-guard 43 is formed integral with the hammer-block 12 and moves with the driver at all times. Its under side, back of its front end, may, however, be slightly recessed or cut away, so that the driver 13, which is of spring sheet metal, may yield a little under any irregularities in the surface of the glass. In this construction the front wall of the opening through the foot 11 extends downwardly only to the upper face of the driver-guard 43. The operation of this alternative construction will be readily understood from the description hereinbefore given in first describing the machine. An adjusting screw or screws may also be applied to the front of the foot in this alternative construction.

Still another modification of the driverguard is shown in Fig. 10, in which said driver-guard 49 slides within the hammerhead and foot 11 with a movement separate from that of the driver, as in the construction first described, but it is operated differently. In all of the constructions shown the driver 13 is rigidly secured to and moves with the hammer-head 12. In Fig. 10 the arm 30 of the lever B is long enough to enter a slot, 48, in the driver-guard 49 and move said guard in both directions. This slot may be long enough, so that the drivei guard may remain stationary during the first part of the stroke of the arm 30, but should always be so short that when the arm 30 reaches the rear limit of its stroke the front end of the guard will be back as far as the rear wall of the opening through the foot 11. If the driverguard moves back farther than this it will do no harm. As soon as pressure on the lever B is released and the arm 30 is thrown forward it engages the front wall of the slot 48 in the driver-guard and carries it forward into the position shown in Fig. 10, the hammer-block and driver meanwhile being held back by their retaining-pawl until said pawl is released by the endof lever B. Thus it will be seen that when the driver makes its forward stroke the driver-guard and under side of the foot at the front form a continuous guard over the driver to hold the point down.

If desired, a pawl and dog may be used as an equivalent retaining-pawl in place of the lever-pawl17. Such a pawl and dog is illustrated in Figs. 10 and 11, and it has the advantage of being very easily tripped and of holding surely, while it is also very durable. 45 is the pawl and 46 the holding-dog, which is pressed upon by the spring 47. Figure 11 shows the pawl locked into engagement with the guide-rod 14, and Fig. 10 shows the same parts unlocked by means of the end of lever B striking the long arm of the dog the same as it strikes the long arm of the pawl 17, first described. In the construction first described the engaging-faces of the notch and pawl 17 were just abrupt enough to have the pawl stay in in place, while in Figs. 10 and 11 the faces are more inclined, so that when the dog 46 releases the pawl 45 it will slip up out of the notch 16, under the pressure of the driving-spring 15.

The revolving receptacle formed with a slot or open space at the periphery between two circular flanges which flare outwardly away from each other not only performs the function of delivering the points in an edgewise direction into the chute, but by being so formed as to direct the points through the narrow peripheral slot it not only delivers them edgewise, but will retain within it any bent points, or those of an excessive thickness or imperfection, so that none but flat points of a given thickness are delivered from said receptacle. It may therefore be used independently of the rest of the machine for assorting the points, and when so used it might be enlarged by the addition of like flanges, so as to increase the number of delivery-slots. An illustration of a receptacle provided with three delivery-slots for this purpose is shown in Fig. 5.

I claim as my invention-- 1. In a machine for acting on glazicrs points, substantially as described, a revolving receptacle for delivering said points, having circular flanges flaring outwardly from each other and rigidly connected together, with a thin delivery-space at the periphery between the confronting faces of two adjoining flanges, substantially as described, and for the purpose specified.
