10 Claims.
This invention relates to a device for applying plastic materials, and more particularly to an applicator device for applying putty to the edges of a window frame and pane of glass.
In replacing a window pane it is the usual practice to applythe putty or other plastic material by the use of a painters or 'glaziers putty knife or other similar tool. It is practically impossible by such a method to apply the putty uniformly along the edge of the glass. Such a method not only results in an unsightly application .but requires considerable time and makes a relatively simple job expensive.
It is, therefore, an important object of the present invention to provide means and a mode of operation whereby plastic materials are applied more efficiently, at less expense, and with a more pleasing appearance.
Another object of the present invention is to provide a plastic applicator structure which is inexpensive in construction, easily'and rapidly operated, substantially automatic in action and unlikely to get out of repair.
A still further object of this invention is to provide an applicator device for applying putty to window sash frames and similar structures which is either hand operated or automatically operated as the device rolls along the surface of the window glass and an edge of a window frame. It is to be understood, however, that the device of this invention may be arranged with a power drive, such as an electric or other type of motor.
The novel features believed to be characteristic of the present invention are set forth with particularity in the appended claims. The invention itself, however, both as to its organization and manner of construction, together with further objects and advantages thereof, may best be understood by reference to the following description taken in connection with the accompanying drawings, in which:
Figure 1 is a view in elevation illustrating a device, constructed in accordance with the principles of this invention, in an operative position relative to a window on which putty is being applied;
Figure 2 is an enlarged transverse cross-sectional view of the applicator device illustrated in Figure 1 taken substantially in the plane indicated by the line II-II;
Figure 3 is a vertical cross-sectional view, with parts in broken elevation, taken substantially in the plane indicated by the line IIIIII of Figure 2;
Figure 4 is an end view, as seen from the left,
of the applicator device illustrated in Figure 2; Figure 5 is a vertical cross-sectional view, with parts in elevation, taken substantially in the pla'ne'indicated by the line VV of Figure 3, when looking in the'direction of the arrows;
Figure 6 is a view similar to Figure 4 illustrating the opposite end of a modified form of putty applicator; and
Figure 7 is a cross-sectional view, with parts in broken elevation, taken substantially in the plane indicated by the line VII-VII of Figure 3, and looking in the direction of the arrows.
The device forming the subject matter of this application is a hand or power driven tool ar ranged to be operated along and in spaced alignment with the edges of a window sash and an inserted window pane. 7
Referring to Figure 1, there is illustrated a window and window frame structure H] of conventional design in which the upper two window panes H and I2 have already had the beveled ribbons of 'putty [3 applied to form water tight joints therefor. The window panes l4 and I5 are illustratedas being held in place within the window sash by means of a plurality of glaziers points l6 preliminary to the application of putty.
The putty or plastic applicator I1 is illustrated in operative position on the window pane [4 after having ejected, compressed and smoothed a portion of the ribbon putty joint I3.
As best shown in Figures 2 and 4, the applicator I1 is shaped to provide a reservoir or a container l8 for plastic material such as putty. It is to be'understood, however, that such other plastic materials as cement, thick paint, wax or other similar materials may be used and ejected in much the same manner as will be described for the application of putty hereinafter. A hollow extension I9 is provided at the lower end of the reservoir or container in axial alignment with its longest axis or in a transverse direction, for a purpose to be more fully explained hereinafter.
The container or reservoir I8 is supported by a pair of spaced rollers 20 and 2|. The roller 20 is provided with an axle 22 which passes through bearing supports 23 and 24, the latter being integral extensions of the container. Similarly, the roller 2| is provided with an axle 25 which is supported by th integral bearing supports 26 and 21.
When the roller supported container is placed on the window pane and frame, as shown on Figure 2, the rollers 20 and 2| are maintained in spaced aligned relation from the window sash 28 by means of a guide shoe 29. The guide shoe 29 is L-shaped in transverse cross-section to provide right angularly extending legs and 3|, which seatingly engage against the inside and top surfaces of the sash adjacent the inserted window pane. The guide shoe 29 is connected to an L-shaped leg 32, extending downwardly from the hollow extension l9, by means of rivets 33 and. 34 or other suitable and similar means. The forward end of the guide shoe 29 is curved as at 35 to permit the shoe to ride over a sash portion of the window which extends transversely of the sash along which the applicator is guided.
It is to be noted that the roller axle 22 extends beyond the bearing support 23 for the purpose of supporting a conically shaped roller 36. The roller 36 has a flat peripheral surface 31 at its enlarged end and a conical surface 38 tapering outwardly and terminating at the surface of the axle shaft 22.
The roller 20 is provided with an end recess 39 for receiving a coil spring 40 which embraces the axle shaft 22 and abuts at its outer end against the bearing support 24. Compression of the coil spring 40 urges the conical roller 36 against the upper corner 4| Figure 5.
A spiral conveyor or feed screw 42 is mounted adjacent the bottom of the reservoir or container IS in a manner to project into the hollow extension I9. The spiral conveyor 42 is mounted in a bearing 43 provided in the end wall 44 of the container 18. The spiral blade 45 terminates in a plate flange 46 which abuts against the inner surface of the wall 44 to restrict endwise movement of the conveyor when mounted as shown. The shaft end 4'! of the conveyor, which seats within the bearing 43, carries a gear 48 which is connected to the shaft end by means of a set screw 49. If desired, the end of the shaft 47 may be provided with a recess (not shown) into which the inner end of the set screw 49 seats for more positively connecting the gear to the shaft.
At the opposite end of the spiral conveyor 42 there is provided a pair of circular bearing portions 59 and 5|. As shown in Figure 2, the bearing 59 is of larger diameter than the bearing 5|.
The hollow extension I9 is provided at its outer end with stepped recesses for complementally receiving the bearings 50 and 5|. While a single bearing will satisfactorily support the outer end of the spiral conveyor, it has been found that the provision of a stepped bearing arrangement provides a more satisfactory seal for the plastic materials confined in the container I8.
As best shown in Figures 2 and 3, a baille 52 extends upwardly from the lower inner portion of the hollow extension [9 immediately adjacent the bearing 5|. A rounded recess 53 is provided on the spiral conveyor adjacent the bearing 5! to permit its rotation while at the same time providing a seat for the rounded edge of the baffle 52. It is to be noted that the spiral blade 45 terminates at the inner edge of the rounded recess 53. The inner periphery of the hollow extension !9 also provides a seat for the forward rotating portions of the spiral blade 45..
A cap 54 is internally threaded for engagement with external threads provided at the end of the hollow extension IQ for the purposes of sealing the container 18 and for restricting endwise movement of the spiral conveyor 42. When the gear 48 and the cap 54 are removed, the spiral conveyor 42 is removable through the hollow extension I9. This removal is made possible by the of the sash 28, as shown in provision of a slot 46a in the plate flange 46 whereby the slot and spaces between the blade spirals allow the conveyor to be threaded by the bafile 52.
A threaded recess 55 is provided in the end wall 44 in spaced vertical alignment with the bearing recess 43. A cap screw 56 having an enlarged slotted head 51, a cylindrical shank 58, and a reduced threaded end 59 is threaded into the recess 55 with its shoulder abutting in locked engagement with the outer surface of the end wall 44.
A gear '69 having a larger diameter than the gear 48 and a reduced axially extending flange BI is apertured to slidingly fit around the shank 58 of the cap screw 55. The gear flange BI is slotted as at 62 for a purpose to be now ex plained.
A hand wheel 63, or other equivalent handle means, is provided with a shank 64 terminating in a machined portion 65 which complementally seats within the slot 62. The hand wheel and shank are axially bored to receive therethrough the cap screw shank 58. The hand wheel is provided with a recess for seating the enlarged head 51 of the cap screw.
As shown in Figure 2, the engagement between the slotted gear flange BI and the machined end of the hand Wheel shank B4 is of the jaw clutch construction. By rotating the hand wheel 63, the meshed gears 48 and El] coact to rotate the spiral conveyor 42. The wall 44 has an outwardly extending flange 44a in spaced adjacent relation to the gears 48 and 60 to provide a housing therefor.
As best shown in Figures 2, 4 and 6, the side edges of the open end of the container l8 are flanged as at 65. A spring housing 51 has laterally extending flanges '58 and 59 which terminate in inwardly extending hooks l5 and H for embracing the flanges B6. The spring housing is removed or applied to the container l8 by sliding engagement from the left-hand side, as illustrated in Figure 2. A headed adjustment screw 12 is threadedly inserted through the top wall of the spring housing 61 and is held in adjusted position by the lock nuts 13 and 14.
The free end of the adjustment screw 12 engages against a plate which compresses the coil spring 16 when the adjustment screw is threaded downwardly. The lower end of the coil spring 16 abuts against a movable cover member 71 which is provided with a flexible covering 18 of leather or other suitable material. The leather covering or seal 18 is expansive against the inside surface of the container l8 to clean the wall surfaces thereof of plastic material as the cover is forced in a downward direction.
As best shown in Figures 2, 3, 4 and '7. a discharge conduit !9 is pressed into or otherwise connected to an aperture provided in the hollow extension l9. As shown in Figures 3 and 4, the discharge conduit is angularly disposed relative to the container M3 to feed a ribbon-like body of plastic material directly ahead of the conical roller 35.
When the container I8 is filled with plastic material, such as putty, the adjustment screw 12 is threaded inwardly to compress the coil spring 16 thereby urging the movable cover 11 downwardly to constantly exert a pressure on the plastic material to insure a full feed by the spiral conveyor 42.
The applicator device illustrated in Figure 2 is constructed to be operated entirely by hand.
'The operator grasps the body of the applicator with his left hand to move the device along an edge of the window sash to be filled with the putty. When the device is so used, the discharge conduit 19 is shaped triangular to present a ribbon-like body of putty in seated engagement against the window sash as shown in Figure 5.
The plastic material or putty is ejected by operation of the hand wheel 63 which is turned by the right hand of the operator. The spiral blades 45 are arranged to eject the plastic material when turned in a clockwise direction. This requires that the hand wheel 63 be turned in a counterclockwise direction. If desired, the spiral blades 45 may be arranged to eject the plastic material when turned in a counterclockwise direction, in
which case the hand wheel 63 would be turned in a clockwise direction.
To insure a positive feed of plastic material through the discharge conduit 19 at all times, an additional short spiral blade portion 8| is provided adjacent the outer end of the conveyor 42. As the putty is ejected towards the left, as shown in Figure 2, it is pressed into the rounded recess 53, where the baffle 52 directs it in a right angular direction through the discharge conduit 19.
Axially extending ribs l9a and l9b are provided in spaced relation around the inner periphery of the hollow extension l9 and the bottom wall of the container l8 to closely engage the spiral blades 45 and 8|. These ribs act as scrapers to feed the plastic material more positively to the rounded recess 53 By so doing, it has been found thata much less force is necessary to turn the spiral conveyor 42 than if the blades were I spaced from the adjacent'walls of the containers as they are shown atsthe rear end of the conveyor inFigure 2.
The triangular ribbon-like body of putty (Figure 7) is laid against the right angular surfaces of the sash 28 and the window pane l4 (Figure The spring pressed conical roller follower 36 then compresses the ribbon of putty to tightly seat it in position and to smooth its sloping surface to effect a pleasing finished appearance. necessary, the ribbons of putty joining at the Window corners may be smoothed by a glaziers putty tool.
It is to be noted that the applicator device illustrated in Figure 2 ejects the putty at a linear 5 speed independent of the moving speed of the device itself by reason of the hand operation of the spiral conveyor.
In Figure 6, there is illustrated a modified form of an applicator device. Like parts are indicated by similar characters of reference throughout the several views.
In this modified form the handle wheel 63 and the gear 60 are eliminated and in their stead are provided a train of gears driven by the rotation of the roller 20a as it follows along the surface of the window pane. Inasmuch as the driving roller 20a operates over the smooth surface of a window pane it is necessary that provision be made for eliminating slippage between the roller and the smooth surface over which it operates. As illustrated in Figure 6, this provision is in the form of a soft rubber tire 82. If desired, the entire roller 20a may be formed of rubber or other suitable gripping material.
The axle 22a is extended sufiiciently to receive a driving gear 83 on one end thereof in alignment with the gear 48 provided on the end of the spiral conveyor 42.
Between the driving gear 83 and the driven gear 48 there is'provided a train of intermediate gears 84 and 85, both of which are suitably carried on axles extending through a combination support bearing and housing 81.
In operation, the applicator device is positioned in the same manner as shown in Figure '2, the right hand of the operator being used to move the device along an edge of the window sash in spaced relation therefrom through the medium of the guide member 29. When moved in a direction towards the left, as shown in Figure 6, the driving roller 20a and the driving gear 83 rotate in a counter-clockwise direction. This motion is transmitted through the intermediate train of gears and drives the driven gear 48 in the opposite or in a clockwise direction thereby rotating the spiral conveyor 42 in a feeding or ejecting direction.
The driving roller 28a, including the provisions just described, is in all other respects the same as the assembly 28 together with the conical pressure roller 35 as shown in Figure 2. The ribbonlike body of putty is ejected through the discharge conduit 19 to be fed directly ahead of the conical roller 36.
It is to be noted that the size of the individual gears comprising the train illustrated may be varied to effect a definite relation between the linear movement of the applicator device and the linear speed of ejection of the putty through the discharge conduit 19. This relation is dependent upon the size of the discharge conduit 19 and the speed at Which the spiral conveyor 42 must necessarily operate to eject a full ribbon of putty as the device is moved along a window sash.
In all other respects operation of the device illustrated in Figure 6 is the same as that shown in Figure 2.
From the above description it will be apparent that there is thus provided an applicator device for plastic materials which not only lays a proper quantity of plastic material in a desired position but compresses the material into tightly seated engagement and smoothes the exposed angular surface to present a pleasing appearance.
While particular embodiments of this invention have been illustrated, it will, of course, be
understood that the invention is not to be limited thereto, since many modifications may be made and, therefore, it is contemplated by the appended claims to cover all such modifications as fall within the true spirit and scope of the present invention.
