To all whom t may concern:
Be it known that l, CHARLES H. Panam- Lnr, a citizen of the United States, residing at the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Automatic Paint- I ing Apparatus; and I do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to Ina-ke and use the same, reference being had to the accompanying drawings, andto the characters of reference marked thereon, which form a part of this specifica-- tion.
.My invention relates to improvements in painting apparatus, my object being to pro'- vide a construction whereby the paint shall be subjected to air pressure for the purpose of feeding it to and through the brush to the surface to be painted, the brush being manually manipulated in the usual Way. My improvement includes an outer tank or receptacle, adapted to receive a smaller tank which is readily removable, in order that the color of the paint, or that dierent kinds of paint may he dispensed through the Ine-` dium of the same apparatus as circumstances may require. Provision is made for connecting the'inner tank or 'receptacle with the outer or larger tank, whereby the paint may pass from the inner tank, through an outlet fixed in the bottom of the larger tank, and pass thence through a valve-controlled openlng into a hose pipe of suitable length which is connected with the handle of the paint brush, the latter being open to allow the paint to pass therethrough, into vand through the head of the brush which is provided with perforations communicating with the longitudinal opening through the handle. Provision is made for introducing cornpressed air into the tank through the medium of a manually operated air pump of ordinary construction, or in anyother suitable manner. Provision is also made for cleaning out the conduit by opening communication between the air pressure in the outer tank and the conduit which is in communication with the paint brush.
Having briefly outlined my present improvement I will proceed to describe the same in detail, reference being made to the accompanying drawing, in which is illustrated an embodiment thereof. In this drawing,-
Figure 1 is a vertical section taken through the two tanks or receptacles, and showing the same connected in operative relation with a paint brush, the handle of which is also shown partly in section.
F ig. 2 is an elevation of the cover for the outer tank shown in connection with the agitator, adapted to -enter the inner tank or paint receptacle.
F ig. 3 is a vertical section taken through the two tanks showing the cover and agitator' removed.
The same reference characters indicate the same parts in all the views.
Let the numeral 5 designate an outer tank or receptacle which is supported upon a base 6 surrounding and extending below the bottom 7 of the tank which is provided with a central opening 8 interiorly threaded to receive an exteriorly threaded outlet pipe 9 Which extends both above and below the bottom, the part below the bottom being provided with a valve l0 Whose valve ieee is connected with an arm l2 with w ich is pivotally connected as shown at 13, a rod 14 which passes through an opening l5 formed in the base 6, its outer extremity being equipped With a hand-hold 16 for convenience of manipulation. rllhe lower extremity of the protruding part of the outlet 9 is in communication with a rigid pipe member 17 which passes through an opening 18 formed in the base 6, its outer extremity being connected in operative relation. as shown at 19 with a flexible hose pipe or conduit 20 Whose opposite extremity is connected as shown at 21 with the outer end of a tube 22 passing'centrally through and forming a part of the handle 23 of the paint brush 24. This tube 22 communicates at the inner extremity of the brush with perforations 25 which pass through the head 26 of the brush and open at the base of the bristle portion 27.
, The outlet 9 extends sufficiently above the bottom 9 of the tank 5, to form a connection' with the bottom of an inner receptacle 28 which holds the paint 29 to be used. The bottom 30 of the receptacle 28 is provided With an opening 3l which communidit cates or registers with an opening 32 in a member 33 made fast to the bottom of the receptacle and interiorly threaded below its opening 32 to coperate with the exterior threads of the pipe 9. The lower portlon of the member 33 is flared outwardly as shown at 34, below the interior threads which. coperate with the exterior threads of the part 9. Hence, when the receptacle 28 is introduced into the tank 5, it is connected with the outlet pipe 9 by turning the receptacle 28 sufliciently to interlock the coperating screw threads of the ad]acent parts 9 and 33.
The upper extremity of the wall of the tank 5 is equipped with a number ofpins 35 adapted to coperate with angle slots 36 formed in the flange 37 of a cover 38 in the center of which is journaled a shaft 39 having agitating blades 40 at its lower extremity and an operating hand crank 41 at its upper extremity. This shaft passes through a stuffing box 42 in the cover, whereby an air-tight joint -isformed around the shaft 39. The outer portion ofthe cover 38 is provided with a circumferential groove 43 in which is located a gasket ring or packing 44 which is engaged by the upper edge 45 of the wall of the tank 5, whereby an airtight joint is formed between the cover and the upper edge of thetank 5. The cover 38 is equipped with an inwardly-opening check valve 46 with-which the hose pipe or conduit 47 of an air pump (not shown), is
connected, throu h the medium of which the pressure withln the tank 5 may be raised to the desired degree, say 100 pounds to the square inch, in order to furnish the necessary pressure, to force the paint 29 through the ath which it must take in order to reach the gristles of the paint brush, as heretofore described.
When the receptacle 28 is originally placed in the tank 5, the opening 32 is closed by a plug 48 which is connected with the lower extremity of a rod 49 whose upper extremity is equipped with an eye 50 for convenience in hand manipulation. After the receptacle 28 is placed within the tank 5 and connected with the outlet 9 as heretofore explained, the
lid or cover 51 may be removed from the receptacle 28, and the plu 48 also removed from the opening 32. T then be placed upon the tank 5 and connected therewith in operative relation through the medium of the bayonet joint connection illustrated, or in any other suitable manner. The shaft 39 may then be turned, whereby the paint within the receptacle 28 may be thoroughly agitated and mixed, whereby it is made homogeneous in character. Up to this time the valve 10 has been closed. As soon as the operator is ready to apply the paint through the valve 10 is opened bymanipulating the e cover 38 mayv may then the medium of the brush 24,
rod 14 or moving it from the full line posi- .tion in Figs. 1 and 3 to the dotted line position in Fig. 3. Before opening this valve, however, the pressure within the tank 5 and upon the paint 29 in the receptacle 28 should 'be raised to the desireddegree through `the introduction of air under pressure by way of the check valve 46, a conduit v47 and a hand pump (not shown), or in any other suitable manner.`
The handle 23 of the paint brush is l .with paint, he presses on the head 57 of the valve piece, whereby the opening 54 is brought into register with the opening of the tube 22. As soon as this occurs the paint is forced through the route or path heretofore described, into the bristle portion 27 of the brush. The operator after the brush is loaded, may release the pressure upon the head 57 when the valve piece 52 will be returned to its normal or closed position; and, as often as a new supply of paint is needed, the operator repeats the pressure on the head 57 of the said valve piece.
The tank 5 is further provided with an opening 58 in its bottom, into which is screwed as -shown at 59, a short pipe member provided with a valve 60, the short pipe member being in communication as shown at 61 vwith the pipe 17 through which the paint passes to the brush. This valve 60 is normally closed, the valve piece being equipped with a crank arm 62 which is connected with a rod 63 for manipulating purposes.
When it is desired to change the kind or color of the paint, the valve l0 will be closed and the valve 60 opened, thus allowing the air pressure in the tank 5 to act through the pipe 17, the hose pipe 20, the brush handle and the brush head for the purpose of clean.- ing out the paint, preparatory to the use of a different kind or color of paint with the apparatus. valve 60 may be closed. the cover 38 of the tank 5 together with the agitator, removed, and the receptacle 28 detached and removed from the tank 5. Another similar receptacle containing) the proper kind or color of paint e put in place and connected with As soon as this is done, the
the tank in the same manner, after which the cover 38 together with the agitator will .be restored to the tank 5 and the operation heretofore described repeated.
In order that the user of the apparatus may be advised when the air pressure is raised to the desired limit within the tank,
the latter is equipped lwith a pressuregage 64 which may be of any suitable construction. i
Having thus described my invention, what I claim is,- A
1. Apparatus of the class described, including a receptacle, a main tan-k adapted to receive the said receptacle, an outlet member connected with the bottom of the tank and extending both interiorly and eXteriorly therefrom, the receptacle being equipped to portion of the tank outlet, a cover for thel be detachably connected with the interior tank, an agitator operably connected' with the cover, andmeans for introducing air underv pressure into the tank.v
