- Figs. 4 and 5 are on a lar er scale than any of the other views.
- Fig. 3 the driver is shown resting on a pane of glass indicated by the numeral 1, with the front end or nose of said driver against a portion of the top, bottom. or side rail, parting rail, or muntin of a window sash. the same being in section, as is the glass, and indicated by the numeral 2.
- Fig. 7 fragmentary portions of the glass and sash member also appear.
- Fig. 8 port-ions of two sash members are shown in cross section, with a pane of glass 3 in section between them, and a fragmentary portion in section of another pane of glass 3.
- the left-hand rail or muntin 2 prevents the driver from being placed flat on the glass. hence necessitates tilting the driver when discharging the points into either of the rails or muntins 2. and requiring that the driver be provided with the auxiliary plate.
- this driver comprises a suitable frame, (usually made in two side sections rivet-ed together.) forming a rear leg 4, a front leg 5, and a handle 7 a springpressed trig 'er pivotally connected at 8 with said frame, which trigger comprises a downwardly-extending arm 9, an upwardly-extending lug 10, and a rearwardly and normally downwardlyextending handle 11: and a foot-piece 12 which is usually made of wood.
- the foot-piece 12 is crosswise of the leg l to which it is attached by means of screws one of which appears at 13 in Fig. 7.
- a spring ll is interposed between the trigger lug and a part of the frame in front of said lug, and normally retains the trigger with the arm 9 in a forward position against a vertical. rear wall 15 within the leg 5.
- a vertical passage 16 that is open at the bottom the full diameter of said passage, and at the top opens through a. constricted orifice 17.
- a vertical passage 18 which opens unrestrictedly through both the top and bottom ends.
- the passage 18 is in cross section diamond shaped and of a size to receive glaziers points. such as those represented at 19, crosswise of said passage. Diamond-shaped glaziers points are with the aid of adhesive material formed into sticks, in the manner well understood those skilled in the art, and the passage 18 is adapted to L'sceive such a stick of points.
- a sheet-metal base plate 22 is provided for the bottom of the leg 5, and said plate is formed with lateral, longitudinallyextending projections or flanges 2323, and with upwardly-extending side pieces 2424 which are punched inwardly to form two projections 25 that are adapted to enter the indentations 20.
- the side pieces 2l are also perforated to receive the bolt 21, which bolt passes through said side pieces and the opening provided for said bolt in the leg 5, to receive on the protruding terminal opposite to the head of said bolt a nut 26.
- the plate 22 extends beneath the open bottom end of the passage 16, and opens directly below the open bottom end of the magazine passage 18, which opening in said plate is indicated by the numeral 29, and corresponds in size and shape with said magazine passage in cross section. diamond shaped and of a size to admit the points 19 to pass through the same.
- the thickness of the plate 22 is approximately the same as that of one of the points 19.
- the flanges 23' form supports and guides for the forward terminal. portion of a sheet-metal driver plate 27 which plate is rolled upwardly and inwardly at the sides to form beads 2828 to receive therein said flanges.
- the base plate 22 is forced up against the bottom of the leg 5, with said leg between the side pieces 24, and in position to enable the projections 25 to snap into the indentations 20, and then the bolt 21 is slipped through said side pieces and said leg and the nut 26 is screwed on to said bolt. If, for any reason, it be desired to remove the plate 22, it is simply necessary to unscrew the nut 26 from the bolt 21, remove said bolt, and loy applying force to the plate snap the projections 25 out of the indentations 20.
- a follower must be provided for the stick or pile of points 19' in the magazine passage 18, to cause said points to be fed properly through the opening 29 in the plate 22, and to this end we provide an inverted U-shaped member 30 which has one leg in said magazine passage and the other leg in the passage 16.
- the spring 31 tends constantly to force the follower 30' downwardly, inasmuch
- the opening 29 is as said spring is compressed between the top of the passage 16 and the collar 31 on the leg of said follower that is in said passage, and thus forces the other leg of said follower to bear on the points 19 in the passage 18, follow downwardly with said points as their number decreases, and cause them to be presented consecutively to the driver plate 27, as will presently be more fully explained.
- the exposed upper portion of the follower is grasped, said follower is elevated against the resiliency of the spring 32 until the leg in the passage 18 is raised clear of said passage, turned or swung in either direction on the other leg until said first-named leg is over one or the other of two ledges 33 that extend laterally from opposite sides of the leg 1, and permitted to descend until the free leg rests on such ledge. Then, after a new stick of points has been inserted in the passage 18 through the top thereof, the follower 30 is swung on the inner leg back into its former position, and permitted to descend under the influence of the spring 32 with the outer leg in the passage 18 on top of the points.
- a horizontal plunger is represented at 34, and this plunger is provided at the bottom with lateral, longitudinallyextending flanges 3535 that are receivable in the driver-plate beads 28.
- the rear end of the plunger 34 at the bottom extends downwardly until it is flush with the bottom of the plate 27 to form a stop 36 for said plate.
- the plate 27 is held against independent endwise movement on the bottom of the plunger 34 by means of he stop 36, and of a vertical pin 37 that is received in a bore in said plun er, and is annularly shouldered at the bottom to form a projection 38 to be received in an opening 39 in the plate 27, as best shown in Figs. 3 and 6.
- the projection 38 has a depth approximately equal to the thickness of the plate 27.
- the plate 27 is engaged by the pin 37, said plate is held with its rear end against the stop 36, and is prevented from moving enclwise independently of said plunger, consequently, when said plunger is moved longitudinally said plate is carried with it, the plate then sliding on the flanges 23 of the plate 22.
- the plate 27 is retained with its front end almost flush with the front end of the plate 22, and closes from below the opening 29 in said plate 22.
- Prefcenter of. the front end portion of the plate 27 is a V-shaped notch 40 that corresponds in size and shape with one-half of one of the points 19, and in said portion on each side of said notch is a slot 41.
- the plunger 34 has a recess 42 therein which opens through the top and rear end thereof, and in said recess, longitudinally of said plunger, and pivotally connected at 43 with said plunger, is an operating lever 44.
- a rod or stem 45 has at the forward terminal aconical part 46, and is screw-threaded back of said part, as represented at 47, and tapped into the rear end of the plunger 34.
- the conical end 46 of the stem 45 is in-the recess 42 beneath the rear end of the lever 44, and said lever is normally retained with said end in contact with said conical end, and with the forward end of said lever in the path of a finger 48 with which the trigger arm 9 is provided, by means of a spring 49 that is received in a bore in the pin 37, and serves the double purpose of normally retaining said lever in the position just described, and said pin with its projection 38 in the plate'opening 39.
- the finger 48 consists of a flat piece of thin metal inserted in a slot in the bottom of the arm 9, the same being held in said slot by means of a pin 50 that extends transversely through said arm and through a horizontal groove in the back side of said flat piece or finger.
- the portion of the arm 9 which is contiguous with the front side extends below the portion of said arm that is contiguous with the back side of the finger 48 to buttress the latter while making its active stroke.
- the finger 48 extends only a. short distance below the longer bottom portion of the arm 9.
- the finger 48 becomes Worn to an extent that necessitates replacing the same with a new finger, the pin 50 is driven out of the arm 9, the old finger is removed from said arm, the new finger is insertedin place of the old, and said pin is again driven into said arm to secure the new finger in place.
- the same or another similar plate is placed in position by slipping the rear end of the same onto the flanges 23 and then sliding said plate rearwardly beneath the plate 22 and the plunger 34, with the beads 28 embracing the flanges 35 as well as the flanges 23, until the back edge of the plate encounters the stop 36 at the rear end of said plunger, when the projection 38 descends into the opening 39, the spring 49 having a constant tendency to force the pin 37 downwardly.
- the plate 27 is slipped into place, it is necessary to force the pin 37 upwardly as the rear end of said plate approaches the projection 38, in order to remove said projection from the path of said end.
- the projection 38 rides on top of the plate 27 between the opening 39 therein and the rear end thereof when the plate is re moved from the plunger, and between said end and said opening when said plate is united with said plunger.
- An exterior flange 51 at the top of the pin 37, prevents said pin from dropping down through the opening provided for the same in the plunger 34, at such times as the plate 27 is not in position to support said pin.
- the foot-piece 12 has a central, horizontal opening 52 therethrough, and in the leg 4 behind said opening is a conical opening 53.
- the rear end of the opening 53 is of the smaller diameter.
- a sleeve 54 has a conical part 55 at the rear end to fit the conical opening 53 in the leg 4, and in front of said conical part said sleeve has an exterior flange 56 which is received in the opening 52 in the foot 12, and is adapted to bear against said leg.
- a check-nut 57 is mounted on the threaded part 47 of the stem 45, behind the plunger 34, to hold said stem against rotation after being adjusted in said plunger.
- a spring 58 encircling the stem 45, is interposed between the flange 56 and the flanged part of the check-nut 57.
- a bearing is provided for the rear terminal of the stem 45, which stem is actually an extension of the plunger 54, and an abutment for the rear terminal of the spring 58, and a construction is provided the parts and members of which can be readily assembled, disconnected, and adjusted, whenever occasion requires.
- the conical head of the sleeve 54 with the seat for said head-in the leg 4, centers said sleeve and enables the same to be retained in its proper position by the spring 58, and to afford an excellent support and hearing for the stem 45, the rear terminal portion of which stem is received in said sleeve and slides back and forth therein whenever the plunger 34 is drawn back and released in the operation of driving a point 19.
- the checknut 57 is loosened, and the stem 45 is rotated in the plunger 34 in the direct-ion to move said plunger rearwardly, and thus to locate a part of the conical end 46 of said plunger which is nearer the apex thereof, and therefore of smaller 'diameter, beneath the rear end of the lever 44.
- the lever 44 is then retained with its front end normally lower than before, with the result that, when the trigger arm 9 is rocked rearwardly, the finger 48 more quickly releases said lever and therefore fails to move said lever with the plunger 34 so far rearwardly as in either of the other cases, and said plunger compresses the spring 58 a less amount than in either of the other cases.
- the check-nut 57 is, of course, tightened each time that the stem 45 is adjusted.
- the driver In operation, the driver is placed flat on the pane of glass 1, with the front endor nose of the base plate 22 against the sash member 2, as illustrated in Fig. 3, the handles 7 and 11 are grasped and the latter compressed, against the resiliency of the spring 13, with the result that the arm 9 wit-h its finger 48 is swung rearwardly, and said finger encounters the lever 44 and forces the same backwardly.
- the lever 44 carries rearwardly with it the plunger 34, against the resiliency of the spring 58, and the driver plate 27 until said plate occupies the position shown in Fig. 7. Then the finger 48 slips off of the lever 44 and therebyreleases the plunger 34 to the spring 58.
- the spring 58 immediately acts to drive forward the plunger 34 and plate 27, until the front end of said plunger strikes the back side of the bottom part of the leg 5.
- This forward movement of the plate 27 is sufliciently forceful and suflicient in distance to drive the point 19 that is in the path of said plate into the sash member 2 to the required depth.
- the driver after forcing one point into the sash member 2, is moved to the right or left the required distance and operated to force in the second point, and so on until the work of securing the pane l with the points 19 is accomplished.
- This plate is preferably made of sheet-metal rolled over at the sides to form beads 60-60 that are adapted to receive within them the beads 28 of the plate 27, and extended up wardly to form ears 6161 which are adapted to grasp between them the side pieces 24 of the base plate 22.
- the projections 20 are punched in the side pieces 24 and thus leave indentations in which to receive projections 62--62 punched in the ears 61. All of these parts must necessarily be properly located relatively. Struck up from the plate 59 at the front end thereof are two protuberances 63, the height of which equals the thickness of the plate 27.
- protuberanees prevent the auxiliary plate 59 from tilting upwardly at the front end and thus closing the discharge opening between the plate 22 and said auxiliary plate, and the slots 41 in the driver plate 27 are in line with said protuberances, and are provided to enable said driver plate to make its full stroke.
- a recess 70 In the front end of the plate 59, between the protuberances 63, is a recess 70.
- the auxiliary plate 59 is slipped on over the front ends of the plates 22 and 27 and into place beneath said plate 27, with the beads 60 outside of the beads 28 and the ears 61 outside of the side pieces 24, and
- the projections 62 are snapped into the indentations formed by the projections 25.
- the front end of the same is a short distance back of the front end of the base plate 22.
- the driver is operated in substantially the same manner as previously described, except that it rests only at the front end on the pane when a point 19 is driven into the sash member.
- the recess in the plate 59 permits the point 19 at the front end to come down almost into contact with the glass, when the driver is positioned ready to discharge said point; otherwise the thickness of said plate woulr intervene and the point could not be driven in to the best advantage for properly securing the glass in its frame.
- a supporting and guiding sleeve 64 is provided for the spindle 45, which sleeve has only the flange 56 at the rear end.
- a cylindrical opening 65 is provided in the leg 4 for the accommodation of the plunger 45 when retracted.
- the driver plate 27 is snapped into place beit to be forced rearwardly into place beneath.
- the base plate 22 and the plunger 34 with the beads 28 embracing the beads 23 and the flanges 35, and also to be forced forwartly and removed from the supporting parts.
- the spring 49 beneath the lever 44 is pocketed in a recess which extends downwardly into the plunger 34 from the top thereof.
- the plate 27 is turned upwardly at the rear end to form a flange 68, and this flange is received in a transverse slot in the bottom of the plunger 34, when the plate is forced rearwardly into place, there being sufficient resiliency in this as in the Fig. 10 construction to enable the plate to be attached to the plunger and detached therefrom.
- the slot for the flange 68 is located in line with the front end of the stop 36, and in the back end of the plunger 34, intermediate of the sides thereof, is a slot 69 adapted to receive therein, from the rear and above the top of said flange, the blade of a screw-driver, or other implement, when the plate 27 is in place, for the purpose of forcing said flange and the rear-end portion of said plate downwardly far enough to enable the flange to clear the front side of its slot, so that the plate can be ISO forced forwardly and withdrawn from the supporting parts therefor.
- a frame hav--ing a leg with a magazine therein for glaziers points, said leg having indentations in the sides thereof, a base plate for the bottom of said leg, said plate being provided with side pieces having projections to enter said indentations, and having therein an opening for the passage therethrough of individual points from said magazine.

Figs. 4 and 5 are on a lar er scale than any of the other views.
In Fig. 3 the driver is shown resting on a pane of glass indicated by the numeral 1, with the front end or nose of said driver against a portion of the top, bottom. or side rail, parting rail, or muntin of a window sash. the same being in section, as is the glass, and indicated by the numeral 2. In Fig. 7 fragmentary portions of the glass and sash member also appear. In Fig. 8 port-ions of two sash members are shown in cross section, with a pane of glass 3 in section between them, and a fragmentary portion in section of another pane of glass 3. In this view the left-hand rail or muntin 2 prevents the driver from being placed flat on the glass. hence necessitates tilting the driver when discharging the points into either of the rails or muntins 2. and requiring that the driver be provided with the auxiliary plate.
In its general aspect this driver comprises a suitable frame, (usually made in two side sections rivet-ed together.) forming a rear leg 4, a front leg 5, and a handle 7 a springpressed trig 'er pivotally connected at 8 with said frame, which trigger comprises a downwardly-extending arm 9, an upwardly-extending lug 10, and a rearwardly and normally downwardlyextending handle 11: and a foot-piece 12 which is usually made of wood. The foot-piece 12 is crosswise of the leg l to which it is attached by means of screws one of which appears at 13 in Fig. 7. A spring ll is interposed between the trigger lug and a part of the frame in front of said lug, and normally retains the trigger with the arm 9 in a forward position against a vertical. rear wall 15 within the leg 5. The parts and members briefly described above are old and well known, and in connection with the same have been used in somewhat different form certain of the parts and members described below and which constitute the new features embodying our invention.
In the leg 5 forward of and formed in part by the wall 15 is a vertical passage 16 that is open at the bottom the full diameter of said passage, and at the top opens through a. constricted orifice 17. Also in the leg 5. in front of the passage 16. is a vertical passage 18 which opens unrestrictedly through both the top and bottom ends. The passage 18 is in cross section diamond shaped and of a size to receive glaziers points. such as those represented at 19, crosswise of said passage. Diamond-shaped glaziers points are with the aid of adhesive material formed into sticks, in the manner well understood those skilled in the art, and the passage 18 is adapted to L'sceive such a stick of points. Thus it is seen that the leg 5 with the passage 18 therein forms a magazine for the points to be expelled from and driven by the machine.
In opposite sides of the leg 5, a short distance above the bottom of said leg, are two indentations, 20, and said leg is bored back of said indentations to receive a horizontal bolt 21. A sheet-metal base plate 22 is provided for the bottom of the leg 5, and said plate is formed with lateral, longitudinallyextending projections or flanges 2323, and with upwardly-extending side pieces 2424 which are punched inwardly to form two projections 25 that are adapted to enter the indentations 20. The side pieces 2l are also perforated to receive the bolt 21, which bolt passes through said side pieces and the opening provided for said bolt in the leg 5, to receive on the protruding terminal opposite to the head of said bolt a nut 26. The plate 22 extends beneath the open bottom end of the passage 16, and opens directly below the open bottom end of the magazine passage 18, which opening in said plate is indicated by the numeral 29, and corresponds in size and shape with said magazine passage in cross section. diamond shaped and of a size to admit the points 19 to pass through the same. The
thickness of the plate 22 is approximately the same as that of one of the points 19. The flanges 23' form supports and guides for the forward terminal. portion of a sheet-metal driver plate 27 which plate is rolled upwardly and inwardly at the sides to form beads 2828 to receive therein said flanges.
In assembling, the base plate 22 is forced up against the bottom of the leg 5, with said leg between the side pieces 24, and in position to enable the projections 25 to snap into the indentations 20, and then the bolt 21 is slipped through said side pieces and said leg and the nut 26 is screwed on to said bolt. If, for any reason, it be desired to remove the plate 22, it is simply necessary to unscrew the nut 26 from the bolt 21, remove said bolt, and loy applying force to the plate snap the projections 25 out of the indentations 20.
Necessarily a follower must be provided for the stick or pile of points 19' in the magazine passage 18, to cause said points to be fed properly through the opening 29 in the plate 22, and to this end we provide an inverted U-shaped member 30 which has one leg in said magazine passage and the other leg in the passage 16. On the inner end of the follower leg which is in the passage 16 is a flange or collar 31, and interposed between said collar and the part at the top of? said passage in which is the constricted opening 17 is a spring 32. That portion of the follower 30 which connects the two legs thereof is above the leg 5'. The spring 31 tends constantly to force the follower 30' downwardly, inasmuch In other words, the opening 29 is as said spring is compressed between the top of the passage 16 and the collar 31 on the leg of said follower that is in said passage, and thus forces the other leg of said follower to bear on the points 19 in the passage 18, follow downwardly with said points as their number decreases, and cause them to be presented consecutively to the driver plate 27, as will presently be more fully explained.
lVhen it is desired to load the magazine with points, the exposed upper portion of the follower is grasped, said follower is elevated against the resiliency of the spring 32 until the leg in the passage 18 is raised clear of said passage, turned or swung in either direction on the other leg until said first-named leg is over one or the other of two ledges 33 that extend laterally from opposite sides of the leg 1, and permitted to descend until the free leg rests on such ledge. Then, after a new stick of points has been inserted in the passage 18 through the top thereof, the follower 30 is swung on the inner leg back into its former position, and permitted to descend under the influence of the spring 32 with the outer leg in the passage 18 on top of the points.
It will be observed that the top of that portion of the leg 5 in which the passage 18 is located, to form the magazine for the points 19, is some distance below the top of that portion of said leg in which is located the passage 16, and that the ledges 33 are on a level with the top of said magazine, otherwise the follower 30 could not be withdrawn from the magazine for the purpose of replenishing the latter.
A horizontal plunger is represented at 34, and this plunger is provided at the bottom with lateral, longitudinallyextending flanges 3535 that are receivable in the driver-plate beads 28. The rear end of the plunger 34 at the bottom extends downwardly until it is flush with the bottom of the plate 27 to form a stop 36 for said plate. The plate 27 is held against independent endwise movement on the bottom of the plunger 34 by means of he stop 36, and of a vertical pin 37 that is received in a bore in said plun er, and is annularly shouldered at the bottom to form a projection 38 to be received in an opening 39 in the plate 27, as best shown in Figs. 3 and 6. The projection 38 has a depth approximately equal to the thickness of the plate 27. hen the plate 27 is engaged by the pin 37, said plate is held with its rear end against the stop 36, and is prevented from moving enclwise independently of said plunger, consequently, when said plunger is moved longitudinally said plate is carried with it, the plate then sliding on the flanges 23 of the plate 22. Normally the plate 27 is retained with its front end almost flush with the front end of the plate 22, and closes from below the opening 29 in said plate 22. Prefcenter of. the front end portion of the plate 27 is a V-shaped notch 40 that corresponds in size and shape with one-half of one of the points 19, and in said portion on each side of said notch is a slot 41. Obviously, if the plate 27 be drawn rearwardly until the notch r 40 is in alignment with the back half of the point opening 29 in the plate 22, a point 19 will drop or be forced down out of said opening into said notch in position to be driven forward, while the point 19 immediately 7 above the one first mentioned will move downwardly into said opening from which this second point can not escape until the plate 27 is again retracted. This is assuming that there is something beneath the plate 27 to prevent the points from dropping or being forced out through the opening 29 and the notch 40 when the plate 27 is retracted.
The plunger 34 has a recess 42 therein which opens through the top and rear end thereof, and in said recess, longitudinally of said plunger, and pivotally connected at 43 with said plunger, is an operating lever 44. A rod or stem 45 has at the forward terminal aconical part 46, and is screw-threaded back of said part, as represented at 47, and tapped into the rear end of the plunger 34. The conical end 46 of the stem 45 is in-the recess 42 beneath the rear end of the lever 44, and said lever is normally retained with said end in contact with said conical end, and with the forward end of said lever in the path of a finger 48 with which the trigger arm 9 is provided, by means of a spring 49 that is received in a bore in the pin 37, and serves the double purpose of normally retaining said lever in the position just described, and said pin with its projection 38 in the plate'opening 39.
The finger 48 consists of a flat piece of thin metal inserted in a slot in the bottom of the arm 9, the same being held in said slot by means of a pin 50 that extends transversely through said arm and through a horizontal groove in the back side of said flat piece or finger. The portion of the arm 9 which is contiguous with the front side extends below the portion of said arm that is contiguous with the back side of the finger 48 to buttress the latter while making its active stroke. The finger 48 extends only a. short distance below the longer bottom portion of the arm 9.
WVhen the finger 48 becomes Worn to an extent that necessitates replacing the same with a new finger, the pin 50 is driven out of the arm 9, the old finger is removed from said arm, the new finger is insertedin place of the old, and said pin is again driven into said arm to secure the new finger in place.
Whenever, because of wear, or for any other reason, it is desired to remove the plate 27, some suitable instrument is applied to the exposed end of the projection 38 and the pin 37 is forced upwardly or, inwardly against the resiliency of the spring 49, until said projection is clear of the plate opening 39, thus releasing the plate, and then the latter is slipped forwardly until it clears the flanges 35 and 23. The same or another similar plate is placed in position by slipping the rear end of the same onto the flanges 23 and then sliding said plate rearwardly beneath the plate 22 and the plunger 34, with the beads 28 embracing the flanges 35 as well as the flanges 23, until the back edge of the plate encounters the stop 36 at the rear end of said plunger, when the projection 38 descends into the opening 39, the spring 49 having a constant tendency to force the pin 37 downwardly. \Vhen the plate 27 is slipped into place, it is necessary to force the pin 37 upwardly as the rear end of said plate approaches the projection 38, in order to remove said projection from the path of said end. The projection 38 rides on top of the plate 27 between the opening 39 therein and the rear end thereof when the plate is re moved from the plunger, and between said end and said opening when said plate is united with said plunger.
An exterior flange 51, at the top of the pin 37, prevents said pin from dropping down through the opening provided for the same in the plunger 34, at such times as the plate 27 is not in position to support said pin.
The foot-piece 12 has a central, horizontal opening 52 therethrough, and in the leg 4 behind said opening is a conical opening 53. The rear end of the opening 53 is of the smaller diameter. A sleeve 54 has a conical part 55 at the rear end to fit the conical opening 53 in the leg 4, and in front of said conical part said sleeve has an exterior flange 56 which is received in the opening 52 in the foot 12, and is adapted to bear against said leg. A check-nut 57 is mounted on the threaded part 47 of the stem 45, behind the plunger 34, to hold said stem against rotation after being adjusted in said plunger. A spring 58, encircling the stem 45, is interposed between the flange 56 and the flanged part of the check-nut 57. In the manner and by the means explained above, a bearing is provided for the rear terminal of the stem 45, which stem is actually an extension of the plunger 54, and an abutment for the rear terminal of the spring 58, and a construction is provided the parts and members of which can be readily assembled, disconnected, and adjusted, whenever occasion requires. The conical head of the sleeve 54, with the seat for said head-in the leg 4, centers said sleeve and enables the same to be retained in its proper position by the spring 58, and to afford an excellent support and hearing for the stem 45, the rear terminal portion of which stem is received in said sleeve and slides back and forth therein whenever the plunger 34 is drawn back and released in the operation of driving a point 19.
If it be desired to compress the spring 58 to a greater extent, in order to obtain more force in the blows that drive forward the points 19, the checknut 57 is loosened, and the stem 45 is rotated in the plunger 34 in the direct-ion to move said plunger rearwardly, and thus to locate a part of the conical end 46 of said plunger which is nearer the apex thereof, and therefore of smaller 'diameter, beneath the rear end of the lever 44. This causes the lever 44 to be positioned by the spring 49 with the front end of said lever normally higher than it was before, and necessitates a greater rearward travel of the finger 48 before it can pass clear of and release said lever, with a correspondingly greater backward movement of the plunger 34, and a consequently greater compression of the spring 58. In the event it be desired to have the spring 58 exert less force in driving the plunger 34 forwardly, the check-nut 57 is loosened, and the stem 45 is rotated in the direction to move the conical end 46 farther forward beneath the contiguous end of the lever 44. The lever 44 is then retained with its front end normally lower than before, with the result that, when the trigger arm 9 is rocked rearwardly, the finger 48 more quickly releases said lever and therefore fails to move said lever with the plunger 34 so far rearwardly as in either of the other cases, and said plunger compresses the spring 58 a less amount than in either of the other cases. The check-nut 57 is, of course, tightened each time that the stem 45 is adjusted.
In operation, the driver is placed flat on the pane of glass 1, with the front endor nose of the base plate 22 against the sash member 2, as illustrated in Fig. 3, the handles 7 and 11 are grasped and the latter compressed, against the resiliency of the spring 13, with the result that the arm 9 wit-h its finger 48 is swung rearwardly, and said finger encounters the lever 44 and forces the same backwardly. The lever 44 carries rearwardly with it the plunger 34, against the resiliency of the spring 58, and the driver plate 27 until said plate occupies the position shown in Fig. 7. Then the finger 48 slips off of the lever 44 and therebyreleases the plunger 34 to the spring 58. The spring 58 immediately acts to drive forward the plunger 34 and plate 27, until the front end of said plunger strikes the back side of the bottom part of the leg 5. This forward movement of the plate 27 is sufliciently forceful and suflicient in distance to drive the point 19 that is in the path of said plate into the sash member 2 to the required depth. Meanwhile, the
handle 11 is released and the spring 13 acts to swing the arm 9 forwardly until it encounters the wall 14 and locates the finger 48 forward of the lever 44 in position ready to act on said lever again when said handle is swung upwardly a second time, said finger, in its forward travel to initial position, riding over the top of said lever and momentarily rocking the same downwardly forward of the pivot 43, against the resiliency of the spring 49. It should be noted in passing that, normally, the spring 58 retains the plunger 34 with its front end against the base of the leg 5.
The driver, after forcing one point into the sash member 2, is moved to the right or left the required distance and operated to force in the second point, and so on until the work of securing the pane l with the points 19 is accomplished.
In many cases it is impracticable or impossible to place the driver fiat on the glass, and then, in order to insert the points 19, it is necessary, while holding the nose of the driver on the glass against the sash member, to tilt the driver so that the rear end is raised above said glass, somewhat as shown in Fig. 8. Vith the driver as thus far described held in the position just noted, the points 19 drop through the notch 40 in the driver plate 47 when retracted, into a position where said plate would not act successfully on the points, hence itis necessary to provide the driver with an auxiliary plate as 59, for use upon occasions such as those last above mentioned. This plate is preferably made of sheet-metal rolled over at the sides to form beads 60-60 that are adapted to receive within them the beads 28 of the plate 27, and extended up wardly to form ears 6161 which are adapted to grasp between them the side pieces 24 of the base plate 22. The projections 20 are punched in the side pieces 24 and thus leave indentations in which to receive projections 62--62 punched in the ears 61. All of these parts must necessarily be properly located relatively. Struck up from the plate 59 at the front end thereof are two protuberances 63, the height of which equals the thickness of the plate 27. These protuberanees prevent the auxiliary plate 59 from tilting upwardly at the front end and thus closing the discharge opening between the plate 22 and said auxiliary plate, and the slots 41 in the driver plate 27 are in line with said protuberances, and are provided to enable said driver plate to make its full stroke. In the front end of the plate 59, between the protuberances 63, is a recess 70.
Before using the driver for inserting the points 19 in the sash members 2 when close together, as in Fig. 8, the auxiliary plate 59 is slipped on over the front ends of the plates 22 and 27 and into place beneath said plate 27, with the beads 60 outside of the beads 28 and the ears 61 outside of the side pieces 24, and
the projections 62 are snapped into the indentations formed by the projections 25. When the auxiliary plate 59 is in place, the front end of the same is a short distance back of the front end of the base plate 22.
With the auxiliary plate 59 in place, the driver is operated in substantially the same manner as previously described, except that it rests only at the front end on the pane when a point 19 is driven into the sash member.
The recess in the plate 59 permits the point 19 at the front end to come down almost into contact with the glass, when the driver is positioned ready to discharge said point; otherwise the thickness of said plate woulr intervene and the point could not be driven in to the best advantage for properly securing the glass in its frame.
In Fi 9, a supporting and guiding sleeve 64 is provided for the spindle 45, which sleeve has only the flange 56 at the rear end. In this case a cylindrical opening 65 is provided in the leg 4 for the accommodation of the plunger 45 when retracted.
In the modification illustrated in Fig. 10,
the driver plate 27 is snapped into place beit to be forced rearwardly into place beneath.
the base plate 22 and the plunger 34, with the beads 28 embracing the beads 23 and the flanges 35, and also to be forced forwartly and removed from the supporting parts. Here the spring 49 beneath the lever 44 is pocketed in a recess which extends downwardly into the plunger 34 from the top thereof.
In the modification illustrated in Figs. 11. and 12, the plate 27 is turned upwardly at the rear end to form a flange 68, and this flange is received in a transverse slot in the bottom of the plunger 34, when the plate is forced rearwardly into place, there being sufficient resiliency in this as in the Fig. 10 construction to enable the plate to be attached to the plunger and detached therefrom. The slot for the flange 68 is located in line with the front end of the stop 36, and in the back end of the plunger 34, intermediate of the sides thereof, is a slot 69 adapted to receive therein, from the rear and above the top of said flange, the blade of a screw-driver, or other implement, when the plate 27 is in place, for the purpose of forcing said flange and the rear-end portion of said plate downwardly far enough to enable the flange to clear the front side of its slot, so that the plate can be ISO forced forwardly and withdrawn from the supporting parts therefor.
Minor changes in the shape, size, construe tion, and arrangement of the parts of this invention, in addition to those hereinbefore specifically pointed out, may be made without departing from the spirit of said invention,
