Specification of Letters Patent.

Patented J an. 26, 1915.

Application filed April 29, 1912. Serial N0. 693,792.

To all whom it may concern:

Be it known that 1, JAMES G. Monius, citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Putty-Trowels, of which the following is a specification.

My invention relates to new and useful improvements in putty trowels.

The object of the invention is to provide a device of the character described which is primarily designed to be used in glazing for the purpose of applying putty or other similar plastic material along the panes of glass in a sash or other framework.

With the above and other ob ects 1n view, the invention has particular relation to certain novel features of construction and operation, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 is a side view of the complete device. Fig. 2 is a sectional side elevation thereof. Fig. 3 is an end view of the device looking toward the point of the trowel. Fig. 4 is a diagrammatic fragmentary view of a window sash, showing the device in use in applying putty along the pane. Fig. 5 is a plan view of the trowel knife, and Fig. (3 is an edge view thereof.

Referring now more particularly to the drawings wherein like numerals of reference designate similar parts in each of the figures, the numeral 1 refers to a receptacle which is cylindrical in shape and preferably of a size to be readily grasped by the hand. One end of this receptacle is open, but is provided with a suitable removable cap 2. The other end of the receptacle converges to an apex, forming a discharge nozzle 3.

This receptacle is designed to contain the putty or the plastic material to be used.

The numeral 4 refers to a plunger which is operated by plunger rod 5, to the inner end of which the plunger 4 is firmly secured. This rod slides through a suitable bearing in the cap 2 and its outer end is provided with a grip 6, by means of which the plunger may be manually reciprocated. Surrounding the plunger rod 5 and operating in resistance to the plunger l: and the cap 2 is a strong coil spring 7, which tends to force the plunger 4 against the putty.

The numeral 8 refers to the trowel knife which is secured to a cap 9 which is secured over the discharge end of the nozzle 3. This cap is provided with a triangular shaped discharge outlet 10, through which the putty is forced by the pressure of spring 7. The putty knife may either be an oblong fiat blade, as shown in Figs. 1 and 2, or may be shaped so as to conform to the angle of the pane and the frame in which it is to be secured, as shown in Figs. 5 and 6.

When it is desired to use this device, the plunger and its operative mechanism and the cap 2 is removed, and the receptacle 1 filled with putty. The plunger is then forced into the receptacle and the cap 2 is secured thereon, as shown in Fig. 2. The pressure of spring 7 operates to force the putty through the discharge opening 10, in a string triangular in cross section, which fits closely in the angle formed by the pane of glass and the casing. As the device is moved along, the knife 8 acts as a trowel and forces the discharged putty firmly in place and causes it to adhere to the casing and pane and secures the latter in the former. T have also provided a cut off valve 11 which is arranged to close the discharge opening 10 when the device is not in use.

While this device is primarily intended to be used for securing panes of glass in a supporting frame, it may also be used for any similar purpose, where the application of putty, or a similar plastic material may be required.

What I claim is 1. In a device of the character described including a cylindrical shaped casing, open at one end and converging to a nozzle at the other end, said nozzle being provided with a V-shaped discharge opening, a cap secured over said nozzle and conforming in shape thereto and provided with a V-shaped discharge opening which coincides with the nozzle opening, a valve for closing said discharge opening, a detachable broad flat blade secured to said cap, a removable cap provided to be secured over the opening of said casing, a plunger arranged to reciprocate in said receptacle and force the contents thereof through the nozzle and the opening of said nozzle cap, a resilient member operating against said plunger and tending to force the same against the receptacle contents and means whereby said plunger may be manually reciprocated.

2. In a device of the character described,

the combination with a cylindrical shaped casing open at one end and converging to a nozzle at the other end, said nozzle being provided with a discharge opening, a cap secured over said nozzle and conforming in shape thereto and provided With a V- shaped discharge opening which coincides With the nozzle opening, a valve for closing said discharge opening, a detachable blade secured to said cap, a removable cap provided to be secured over the open end of said casing, a plunger arranged to reciprocate in said receptacle and force the contents thereof through the nozzle and the opening of said nozzle cap and a resilient member 15 operating Within said receptacle and against said plunger, tending constantly to force said plunger against the receptacle contents and a means whereby said plunger may be manually reciprocated.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

JAMES G. MORRIS.
