ADAPTER TYPE DISPENSING CAP FOR GLAZIER'S PUTTY CONTAINERS Filed June 17, 1955 52 6 INVENTOR.
tates AFTER TYPE DISPENSING CAP FOR GLAZHERS PUTTY CONTAINERS This invention, relating generally to the art of installing a pane of window glass in an associated sash or frame, comprises a dispensing cap capable of being substituted for the conventional closure cap of a collapsible container holding a quantity of glaziers putty, to cause the putty to be dispensed from the container in a ribbonlike form having a predetermined cross sectional shape especially suited for facilitating the puttying of the glass in the frame.
When a pane of glass is being installed in a sash, the conventional practice is to apply the putty needed for carrying out the task in a manner which is highly dependent on the skill of the worker so far as molding the putty to a proper cross sectional shape, uniform over the full periphery of the glass, is concerned.
The main object of the present invention is to provide means which will speed up and otherwise facilitate the application of the putty in the desired, molded cross sectional shape, with correspondingly less dependence on the skill of the particular worker as regards the producing of a neat, efficient installation of the glass.
A more specific object is to provide a dispensing cap connectible to the neck of a collapsible tube holding a quantity of glazing compound, in substitution for a conventionally formed closure cap, which dispensing cap will have an outlet the configuration and cross sectional area of which are such as to produce, when the compound is squeezed out of the tube through the cap, a ribbon of corresponding cross sectional configuration, which may be laid down along the joints between the sash and window pane in such a manner that there exists only the further necessity of pressing the ribbon into sealing relation to the joint with a putty knife or like tool.
Another object is to provide a set of dispensing caps, any one of which may be used on a single tube of 00111- pound, having openings of difierent shapes and sizes, that will permit successive applications of the compound, one before the glass is inserted in the sash channel and a second to be applied following insertion of the glass to provide an exterior seal.
A further object is to provide, in said set, caps having outlets of dilferent sizes but of corresponding configurations, to permit use of a cap selected according to the depth of the channel in which the pane is being installed.
A further object is to provide one or more dispensing caps as described, capable of being manufactured each from a single molded piece of plastic material or the like, at relatively low cost, and capable of being cleaned with minimum difficulty following use.
Other objects will appear from the following description, the claims appended thereto, and from the annexed drawing in which like reference characters designate like parts throughout the several views and wherein:
Figure 1 is a view showing a collapsible tube fragmentarily and in side elevation, equipped with a conventional closure cap and neck, shown partly in side elevation and partly in longitudinal section;
Figure 2 is a transverse sectional view on line 2-2 of Figure 1;
Figure 3 is a view partly in side elevation and partly in longitudinal section of a dispensing cap capable of being substituted for the cap of Figure 1;
Figure 4 is an end elevational view of the cap of Figure 3, as seen from the left of Figure 3;
Figure 5 is a view similar to Figure 3 showing a second form of dispensing cap;
Figure 6 is a view similar to Figure 4 of the cap of Figure 5;
Figure 7 is a view similar to Figure 3 showing a second form of dispensing cap; and
Figure 8 is a view of the Figure 7 Figure 4.
A collapsible tube 10 holding a quantity of putty or other glazing compound can be made in any desired size, and has at one end an externally threaded, cylindrical neck 12 having a cylindrical, axial bore 14 of constant diameter, normally closed at its outlet end by a conventional closure cap 16 having a cylindrical skirt internally threaded to engage the threads of neck 12.
Adapted to be substituted for the closure cap is a dispensing cap shown in Figures 3 and 4, generally designated 18 and molded from a single piece of plastic material or the like. Cap 13 is formed with a cylindrical body 20 having an axial, end to end bore 21 one end of which is counterbored and threaded at 22 to engage the threads of neck 12. An annular sealing gasket 24 seats upon the shoulder defined at the inner end of the counterbore.
At the end thereof remote from the counterbore 22, the constant diameter, cylindrical intermediate portion of bore 21 merges into a tapered portion 26 of the bore having at its smaller, outer end an outlet 28 smaller in cross sectional area than the area of any other part of the bore along the full length of the bore. Outlet 28 is formed of a rectangular shape, extending as a transverse slot across the outlet end of the dispensing cap, the length of which slot is approximately twice that of the width.
Exteriorly, the body 20 is of cylindrical shape at the counterbored end thereof, while at its outer end, said body is frustro-conically tapered at 30, in general correspondence with the tapered bore portion 26. The tapered part 30 of the body, at the smaller end thereof, is beveled or chamfered as at 31, to provide a steeper external taper of the body at the outlet end thereof facilitating the positioning of said outlet end in relatively confined areas such as at the corner of the sash, without loss of accuracy of the positioning of the device for laying down a ribbon of a cross sectional shape matching that of the outlet 28. A roughened collar 32 on the body facilitates rotation thereof.
The dispensing cap 18 is initially used, before the glass has been inserted in the channel of the window frame, to lay down a bed of putty in the channel.
After the glass has been inserted following the bedding of a ribbon dispensed through cap 18 in the channel of the frame, glaziers points or nails are used to anchor the glass.
As a next step, the user removes cap 18 and applies to neck 12 a cap formed as shown either in Figure 5 or Figure 7, according to the depth of the particular channel. In Figure 5, the cap generally designated 36 has a body 38 formed with an end to end axial bore 40 merging at the outer end of the body into a tapered bore portion provided with an outlet 42 of right triangular configuration. The inner end of the bore 40 is counterbored similarly to the cap of Figure 3 to engage the neck 12.
Externally, body 38 has a shape substantially duplicating that of cap 18, being formed with a tapered outer cap, similar to 3 part 44 having at its smaller end a more steeply tapered lip 45. At the base of the tapered part 44 there is provided a knurled or otherwise roughened collar 46.
The cap 48'of Figures 7 and8 is similar in everyrre spect to the cap 36, except for having a larger outlet, desirable when the channel is of substantial depth. Cap. 48 has-a body 50 formed with an axial-bore 52. Bore 52 does not merge into a tapered bore portion at the outlet end of thecap, but instead extends'directly to an outlet 54 of right triangular configuration, greater in cross sectional-area than outlet 42. Outlet 54, however, like the outlets 28, 42, is smaller in crosssectional area than the area of any other portion of the bore'of its associated cap.
A counterbore 56 at the inner-end of the bore '52 en gages neck 12, while a roughened collar 58 is provided on the body intermediate opposite ends thereof.
The body 50 has an externally tapered portion 60' merging at its smaller end intoa more steeply tapered lip 62 facilitating better vision of the ribbon being dispensed.
Ribbons dispensed through caps 36, 48 would have a cross sectional shape of a right triangle, so as to fit inthe angle defined between the inserted pane and the as-- knife is held in the other hand, following the tube during; the dispensing of the compound. Thus, the entire in-'- stallation of the pane can be carried out in minimumtime, by a relatively unskilled worker, while still assuring a neat, professional appearance to the finished installation, as well as an efficient seal of the pane in the frame.-
It is believed apparent that the invention is not necessarily confined to the specific use or uses thereof described above since itmaybe utilized for any purpose to which it may be suited. Nor is the invention to be necessarily.
limited. to the specific construction illustrated and de-- scribed, since suchconstruction is only intended to be illustrativeof the principles, it being considered that the invention comprehends anyminor change in construction that may be permitted within the scope of the appended claim.
