PAINT SPRAYING DEVICE Filed July 9, 1948 Pmad Ney. '22,1949

UNITED STA-'rss PATENT' oFFicE j ananas PAINT srmmNG nnvicn France a. williams. chuan, nl.r Application .my s, 194s, sel-u1 N. anzi 1 l 'I'hls invention relates to certain new and useful improvements in paint spraying devices and has for its principal object the provision of a device of this character which is of a construction and size such as will permit the device to be attached to a portable hand-drill to be operated thereby and carried aboutthereby, thus constituting the device substantially portable.

Another and equally important object of the invention is the provision of a spraying device of the character hereinafter described ywhich is especially designed and constructedfor spraying small parts and other minute equipment.

Another object of the invention is to provide l a spraying device of the character hereinafter described which will serve the purpose of meeting the demand for spraying operations where expensive spraying equipment is not needed or required.

Other objects will appear hereinafter.

'Ihe invention consists in the novel combination and arrangement of parts to behereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings showing the preferred form of construction, and in which:

Fig. 1 is a side elevational view of the invention showing the same in its relationship to an ordinary portable hand drill, in phantom;

Fig. 2 is a plan view of the invention.

Referring more particularly to the embodiment the latter being shown 1 claim. (c1. 29o-sa)- 23 by means of a connecting rod 23. The compressor Il includes a removable perforated cap Y device is supported through the medium of the of the invention shown in the drawings, by which embodiment the several objects of this invention are accomplished, my improved spraying device comprises a clamp I0, This clamp I0 comprises Corresponding end porconfronting plates I I.

. tions I2 of these plates are connected together by a nut bearing bolt I3.

The plates Il intermediate their end portions provide together a band or ring I4 which is adapted to clampingly embrace a pump or compressor I5. The compressor I5 is clamped between the plates by a nut bearing screw I6. The opposite end portions of the plates. I I are formed to provide an open clamp I8 which is adapted to clampingly embrace the supply tank or container I 3. This container I9 provides a removable cap 20. Carried by this cap 20 and extending into the container I 9 is a supply tube 2|. This tube 2| terminates into a restricted end portion 22 in proximity to a nozzle 23.' This nozzle 23 is supported by a bracket 24 secured to the cap 20 as at 25. The compressor I5 may be of any approved construction including an operating` shaft 26 having a crank 21 to which is connected a piston shaft 23 from the hand drill 32. The compressor I 5 through the medium of the shaft 26 is connected to the chuck 3| of the hand drill and is driven thereby. Through the medium of the clamp I 0 the container in turn is connected and supported from the compressor I5. The compressorv I5 has connection with the nozzle 2li through the medium of a pipe 33 extending from the bottom of the compressor as at 34. This pipe 33 is detachably connected to the nozzle 23 by a flexible hose link 35.

To reilll the container I3, the cap 20 may be removed therefrom with the nozzle 23 detached from the pipe 33.

For cleansing purposes the entire container I9 may be removed from the open clamp I8.

The several parts in their relation with respect to each other provide a device which is relatively small and light in character. This affords manipulating the device during spraying operation with ease and effectiveness by and through the operation of the hand drill 32 to which the device isconnected and which serves as the means of portably supporting the spraying device.

From the foregoing description, it will be obvious that my spraying device is especially adapted for use in spraying small parts and upon occasions when the use of more expensive equipment is not required.

While I have illustrated and described the pr'e ferred form of construction for carrying my invention into effect, this is capable of variation and modification Without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth. but desire to avail myself of such variations and modifications as come within the scope of the appended claim.

Having thus described my invention, what I claim as new and desire to protect by Letters P atent is:
