PAINTING DEVICE.

Specification of Letters Patent.

Patented June 7, 1921.

Application-med February 9, 1920. Serial No. 357,143.

To all whom t may concern:

Be it known that I, FRANKLIN E. FORN- wAL'r, a citizen of the United States, residing at Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented new and useful Improvements in Painting Devices, of which the following is a speciication.

My present invention pertains to painting apparatus and it contemplates the provision of a device whereby paint may be quickly and easily applied and this with a small amount of effort on the part of the operator.

The invention further contemplates the provision of a device through the medium of which paint isl sprayed on to a surface in such manner that the work will present a. finished appearance and through the employment of my novel device one person is enabled to accomplish as much as is now accomplished by approximately ten persons using the ordinary well known paint brush.

The invention in all of its details will be fully understood from the following description and claims when the same are read in connection with the drawings accompanying and forming a part of this specification, in which:

Figure l is a side elevation of my novel paint applying device, and

Fig. 2 is a sectional view of Fig. 1.

Fig. 3, illustrates the peculiar nozzle used in my novel device.

Similar numerals of reference designate corresponding parts in the several views of the drawings. y

The pressure hose 1 of my device is connected to a paint reservoir (not shown) and said reservoir communicates with a compressed air tank not shown. The said hose 1 is threaded or otherwise secured to the tubular shaft or tube 2, and at its upper portion the tube 2 is provided with a series of perforations 3 for an important purpose hereinafter set forth.

- the shaft 2 and is retained in proper position with respect to the shaft by the jam nuts l() and 11. Immediately above the forked portion 9 I arrange the nut 12 that is threaded into the gland nut 13 as illustrated. In other words` it might be said that this construction comprises a nut within a nut. The nut 13 is exterior-ly threaded at 14 and said exterior threads engage the bulletshaped casing 15. The said nut 13 is provided with the portion 17 that confines the packing 16 in its proper place.

The nut 12 at its upper end is V-shaped to receive the packing 16.

Surrounding the upper end of the tube 2 and confined within the casing 15 is a coil spring 18 that bears at its lower end on the portion 17 and its upper end on a pin 2O that passes through the upper yend of the hollow stem or tube 2. The tube 2 has a solld head 2l closing its end which is capable of being seated in the perforated upper end 22 of the casing 15. l

As illustrated by Fig. 2 a tube or conduit 23 is threaded into the portion 22 of the casing and at its lower end the tube 23 communicates with a head 24, as illustrated.

In the practical use of the device, the hose 1 is attached to a paint reservoir and paint is forced by compressed air or otherwise through the tube 2 and thence out of perforations 3 and by manipulation of the handle 8 the velocity of the stream may be increased or decreased according 4to the wish of the operator.

It will be seen by reference to the drawings that the gland nut 12 and nut '13 as well as the casing 15 are slidably movable with relation to the tube 2 and that such relative movement is produced by manipulation of the handle 8 and hence the density of the flow of paint from the device is controlled by manipulation of said handle 8. My novel device may be moved up and down or to the right or left without diminishing the flow of paint, this being `a very advantageous feature because it permits of the operation of the device by one erson.

My device is novel, from the act that, the casin or barrel revolves on the tubular shaft, an .without any motion of the hand grasping the tricker or handle, by turning the barrel (and by means of the curved nozzle) the spray may be directed up and down or to the right or left at will of the operator, without diminishing the flow of paint,

as there is but .one line of hose necessary to convey the fluld and force to this device.

IThe operator by grasping the handle is enabled to control the spray and vary the force at the point of contact at will, which is an important feature of this device.

It will be gathered from the foregoing that my device when taken as a whole is compact and inexpensive to produce and comprises no delicate parts such as are likely to become inoperative after a short period of use.` Moreover, the device maybe readily cleaned with but a little effort and the advantages of this are apparent to those skilled in the art.

lHaving described my invention what I rclaim and desire to secure by Letters-Patent 1s l. In a painting apparatus the combination of a casing interiorly threaded at its lower end, an outlet formed in its upper end, aconduit arranged in the outlet, a tube having orifices arranged therein within casing y, and having a closed end adapted to close said outlet, a nut threaded on the lower interior threads of the casing and secured to and movable with the casing, a gland nut secured to the first named nut and slidably arranged on the tube, jam-nuts on the tube spaced below the last named nut, and a handle having a portion disposed between the jam-nuts and the gland nut for'movement of the gland nut, first named nut and casin relative to the tube.

2. n means for spraying paint and the like the combination of a casing having a discharge opening in its upper end, a tube arranged within said casing, a spring surrounding the tube, perforations formed in the tube, a seat surrounding said discharge opening, a solid head formed on the upper end of the tube for operating with said seat, a nut engaging the lower end ofthe casing and having a packing chamber surrounding said tube, packing in said chamber and a second nut that engages and is confined within the first-named nut and compresses said packing.

3. In a device for the purpose set forth, the combination of a tube having a closed upper end, a 'am nut surrounding the lower end of the tu e, a second jam nut surround ing the tube and arranged above the firstnamed nut, a handle mounted above the secondjam nut and also surrounding the tube,

vthat a a packin nut arranged on the tube above the hand e and slidable thereon, a nut surrounding said acking nut, packing interposed between t e last named nuts, a spring surrounding the tube and bearing at its lower end on the uppermost nut that confines the packing, said tube having perforations formed therein, a pin arranged on the upper end of the tube, and a casing secured to said uppermost nut` and surrounding the tube and having a discharge opening in its upper end, and a seat surrounding said opening that receives the upper closed end of the tube.

4. In means for the purpose set forth, the combination of a casing having a discharge orifice at one endthereof, a tube ar ranged within the casing,'a spring arranged within the casing and surrounding the tube and tending to move the tube toward said discharge orifice, apertures formed inthe tube, a seat formed in the casing surrounding said orifice a solid head formed on the tube for normally engaging said seat to close said orifice, a nut engaging the lower end of the casing and a second nut that engages and is confined within the first-named nut; sald nuts being so constructed and arranged packing chamber is produced about the tube.

5. In a device for the purpose specified, the combination of a casing having a discharge opening at its upper end, a valve seat formed in the casing and surrounding the opening, a tube confined within the caslng and having a solid upper end that normally rests in the valve seat of the casing to close the opening thereof, perforations formed in the tube, a nut secured to the lower end ofthe casing and surrounding the tube, a second nut resting in and secured to the first named nut, a spring surrounding the tube and abutting at its lower end and against the upper surface of the first-named nut, and a pin formed in the solid head of the tube against which the upper end of the spring bears. i i

In testimony whereof I have hereuntolset my hand in witnesses. Y
