Specification of Letters Patent.

Patented June 1, 192i).

Application filed August 18, 1919. Serial No. 319,827.

To all whom. it may concern:

Be it known that I, Vic'ron JANsnN, a citizen of the United States, residing in the city of Los ringeles, county of Los Angeles, and State of California, have invented certain new and useful Improvements in Painters Striping Mechanism, of which the fol lowing is a specification.

This invention embodies improvements in my invention as shown and described in Letters Patent No. 1,305,545, issued to me June 3, 1919.

Ihesalient objects of my present invention are to provide in a device of the-character referred to improved means for storing air under pressure within the device for use in forcing the paint from the reservoir thereof to and through the brush; to provide in connection therewith simple and practical valve mechanisms for controlling the air supply and its use as required; to provide an improved device of the character referred to which can be used in any position and in which the flow of the paint can be kept uniform at all times. Other features of improvement will appear from the following description ofthe same, taken with the accompanying drawings, thereof, in which;-

Figure 1 is a plan of my improved device;

Fig. 2 is a front end view thereof;

Fig. 3 is a longitudinal sectional view therethrough Fig. 4 is a side elevation with parts shown in section; I

Fig. 5 is a cross sectional view taken on line 5--5 of Fig. 3;

Fig. 6 is a rear end View; and

Figs. 7 and 8 are details.

Referring in detail to the drawings, 1 designates a body of cylindrical form with an angle portion 2, adapted to have telescoped thereover a tubular handle 3, having along its under side a smaller tubular portion 1, in which is a plunger 5, normally pressed toward the body 1 by means of a spring 6. The forward end of said plunger carries a holding latch 7, adapted to fit into notches 8, in the edge of a collar 9 around said body, whereby saidv collar can be ad.- justed to diiferent positions to hold a guide bar 10, adjustably secured thereto as indicated by means of a thumb screw 11.. Said bar 10 is provided with an adjustable finger 10 The plunger 5 is provided with an operating pin 5*, by means of which said plunger can be said collar 9.

Mounted in the tubular portion 3, is an enpansible air container or bellows, 12, provided at its forward end with a nozzle 13, 1Jl()]CtlI1g through the end wall 2?, of the body extension 2, as clearly indicated'in' Figs. 3 and 4. 'l. he rear end'of said air container 12 is provided with a cup 14 adapted to hold the end of a coiled spring 15, the other end of which bears against an end cap 3?, of the tubular handle portion 3. A screw ring 16 is provided in said cap 3, and is connected to the end of the expansible air container, or bellows, 12, by means of a cord or chain 17, for extending said bellows for the purpose of filling it with air, in a manner hereinafter referred to.

The body 1 is provided in its upper end wlth a screw plug 18, having a hexagonal,

pulled back at will to release head, 18 and having a central bore therethrough, as shown. A valve sleeve 20 of less diameter, is slidably mounted through sa d plug 18 whereby to admit air through said plug around said sleeve, and is provided at its outer end with a head 20, and at its inner end with a valve member 20", which closes the inner end of said screw plug 18. This controls the air inlet to the bellows. A valve pin 19 is-slidably mounted through said sleeve 20, said head 20 and said screw 20", and is provided with a valve 21, secured thereto, with a spring 22 hearing at one end against the valve member 20* on the sleeve 20, and at its other end bearing against the valve 21. The valve 21 seats against the end wall 1 of the body 1, to control the passage of air therethrough. Said valve pin 19 also extends through said wall 1 and operates as a needle valve ina tubular boss 23, projecting into a reservoir body 2-1, mounted on the end of the body 1, as indicated in Figs. 3 and 4. Said reservoir is provided with a closure 25, as indicated. llt is also provided therein with shot S, or other equivalent means, to fill up the corner of the reservoir to facilitate the dis charge of more of the paint from said reservoir, will be readly understood.

A brush 26, having a tubular center 27,. which registers with the boss 23, is secured to athe reservoir body 24, by means of a bayonet collar as, as indicated, thus making it possible to use different brushes with the same instrument,

An operating lever 29 is pivotally mounted on the handle portion 3 of said device, as at 30, with one end connected with the valve pin 19 by means of a slot and neck connection, a well known construction, and near its other endprovided with an adjustment stop screw 31, for determining the distance said lever 29 can be depressed and consequently, the distance said valve pin 19 can be moved to open the valve 21, toadmit air into said reservoir 24.

The use and operation of my invention may be briefly described as follows: Paint is put into the reservoir member 24 after the closure2-5 is removed. The screw ring 16 is removed and pulled out to extend the air container 12. At the same time the head 20 is pressed inwardly by the thumb to move the sleeve 20 and the valve 20 inwardly so that air can pass through the screw plug 18, around-said sleeve 20, and into the angle member 2 and into said bellows 12 as it is extended The spring 15, of course, is compressed by this action. When the bellows is full, the head 20 is released and is moved outwardly by the spring 22, closing the valve 20". The screw ring 16 can then be put back into place with its chain within' the handle 3. The instrument is now charged with paint and with air and ready for use. In use, it is only necessary to press the lever 29 with the thumb,'acc0rding to the adjustment of the stop screw 31, to admit air past the valve 21 and into the reservoir 24 for forcing the paint out through the boss 23 and the brush 26. The thickness of the paint determines the air pressure needed to force the paint properly out through the brush. When the air container 12 has been compressed by the spring 15, and all the air has been discharged therefrom, it is only- 7 necessary to again extend it, as before.

I am aware that changes in details can be made in my invention as here shown for illustrative purposes, from the spirit thereof, and I do not, therefore, limit the invention to the showing made, except as I may be limited by the hereto appended claims.
