PAINT-DISTRIBUTER.

SPECIFICATION forming part of Letters Patent No. 434,105, dated August 12, 1890.

Application filed November 15, 1889. Serial No. 330,404. (No model.) 7

To all whom it may concern.-

Be it known that 1, CHARLES L. BURDIOK, of Madison, in the county of- Dane and State of WVisconsin, have invented certain new and useful Improvements in Paint-Distributers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon which form a part of this specification.

This invention relates to a novel construction in paint-distributers, and more particularly to that class of such devices known as air-brushes which are adapted for use in painting and shading pictures.

The invention consists in the details of construction and combination of parts hereinafter fully described, and pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a view in side elevation of a device constructed in accordance with my invention. Fig. 2 is a plan view of the same with the cover removed to show the interior construction. Fig. 3 is a detail view of the removable cover.

-Fig. 4 is a-view of the apparatus in central longitudinal section taken 011 the line 4 4. of Fig. 7. Fig. 5 is a longitudinal sectional View taken on the indirect line 5 5. of Fig. 2. Fig. 6 is a longitudinal sectional view taken on the indirect'line 6 6 of Fig. 2. Fig. 7 is an end view of the apparatus. Fig. 8 is a fragmentary sectional view of the paint-receptacle, showing the paint conductor or nibs in cross section.

In said drawings, A indicates the case of the instrument, which is closed at its ends by heads or plates at a. The said case is also di vided into two compartments a a by a partition or diaphragm a*, conveniently located about midway the ends thereof. A part of the case adjacent to the compartment a is cut away, as shown, and said part is providedwith a removable cover A, having suitable devices for securingthe samein position, (herein shown as comprising a flange a2) located at the end and adapted to engage the under side of the case, and a sliding pin or lug a, having a handle projecting through a slot in the case. The said cover is provided, also, with a slot a hereinafter referred to. The compartment is made air-tight, and is provided at its rear end with a short pipe or tube A which has screw-threaded connection with an aperture in the head a of the casing. The tube A communicates with the hose or pipe leading from the apparatus employed for forcing the air. Within an aperture formed in the diaphragm a a nipple b is secured, preferably by a screw-threaded joint. Said nipple 1) extends into the compartment a and is provided with an enlarged or bulging end portion having an aperture or perforation b at one side thereof for the escape of the air.

B indicates a pipe or tube section located within the forward end of the compartment a and provided at its forward end with a nozzle 12 which projects through a slot a in the head Ct. The saidtube B communicates with the nipple b by means of a short flexible tube or hose b which embraces and is secured to the adjacent ends of said tube B and said nipple. The flexible tube 12 is preferably made of rubber, so as to permit the tube B to move freely with relation to the nipple, said flexible tube being secured to said nipple by means of strands of wire or other suitable material, which is wound around the flexible tube in the rear of the perforation 19 The tube B is secured to the case by means.

of a clip or block W, to which said tube is rigidly secured, said block being secured by means of a headed screw 72 which passes through a slot at in the case and enters a screw-threaded opening in said clip. The said clip is conveniently secured to the tube B near the rear end of the latter, and it follows from the construction above described that by loosening the screw 19 said tubeB can be moved longitudinally and then secured in its adjusted position by tightening the screw.

A indicates a set-screw passing through a screw-threaded perforation in the case adjacent to the pipe B and having its inner end adapted to bear against the outer or free end of said pipe, so that by turning said screw A the said pipe B can be moved transversely to the case, it having sufficient flexibility to permit such movement.

. 0 indicates the paint receptacle or holder secured at an angle to the forward end of the case. The said paint-receptacle is formed duced therein by pouring or otherwise. The said head or plate 0 is formed at about its center with a small perforation 0?, through which the paint can escape.

c 0 indicate two small pointed plates or nibs located above and below the perforation 0 between which the paint is conducted from the holder 0. The said nibs are arranged very closely together, so that only a little space is left between them. The said nibs are so located that the space between them is in alignment with the orifice in the nozzle, so

that whenthe said nozzle is moved transversely by the screw A it will always be in alignment with thesaid space between the nibs. It follows from this construction that when an air-blast passes from the nozzle 1) and is projected into the space between the nibs any paint that may be between said nibs will be carried forward in the form ofa fine spray under the influence of said air-blast. The adjustment of the nozzle 11 longitudinally and transversely allows a greater distribution of the paint and also a greater quantity of paint to be acted upon by the air-blast; but these adjustments are in a manner permanent and cannot be made during operation, but it is necessary tostop the work which is being done to make the same To provide means whereby light and heavy lines can be made with this instrument during the progress of the work, 1 construct the nibs c 0 so that they can bebrought together or separated, and thus permit a greater quantity of paint to be acted upon by the air blast. To accomplish this object, the plate or disk forming the head 0 of the paint-holder is made of relatively thin material possessing a certain degree of flexibility, so that the same can be pressed inwardly, and after the pressure is removed the same will resume its normal position. The nibs being seen red directly to said plate 0, it is evident that when the said plate is pressed inwardly the said nibs will be brought together, thereby lessening the space between them and affording a smaller passage for the paint. The means for securing this pressure upon the platec comprises a lever D, pivoted within the ease and having its short arm (1 projecting outside through a slot made in the head a and resting normally in contact with the head 0. The said lever D is preferably pivoted between two lugs cl cl, formed upon an arm or bracket D, which is secured within the forward end of the case. The said arm D passes rearwardly and parallel with the sides of the case to a point about midway of the ends of the compartment a whereupon itis deflected and secured to the side of the case, preferably by means of a screw. The long arm (I of the lever D extends rearwardly to the face of the bracket D and has its edge which is adjacent thereto inclined, so that it is'thinner at its rear end.

E represents a thumb piece or lever pivoted at its lower end to a suitable bar E,

hereinafter to be referred to, and extending upwardly between the inclined'edge of the arm (1 of the lever and the adjacent face of the bracket D. The said thumb-piece E is adapted to swing forwardly and backwardly on its pivot, so that as the same engages the inclined edge of the arm d it will serve to gradually swing the same outwardly in an obvious manner, and thereby press the short arm d against the head 0' of the paint-holder. A set-screw d is arranged in one of two lugs d 61, formed upon the plate in the rearof the lugs d. The head of said set-screw d is arranged for contact with the swinging thumbpiece E when the same moves forwardly, so

that its forward movement can be limited to thereby limit the extent to which the plate 0 of the paint-holderwillbe pressed inwardly to control the flow of paint to the nibs. The said lugs d d are arranged one above and one below the long arm of the lever D, although the same do not come in contact therewith, but extend outwardly to a point adjacent to the pipe B. The said lugs d are arranged a sufficient distance apart to permit the said pipe B to pass between the same when said pipe is moved transversely by the screw A and thus serve to guide said pipe, so that the nozzle 1) will always be in alignment-with the space between the nibs 0 The operating-lever E extends upwardly through the slot (L in the removable cover A of the case, and is provided at its upper end with a suitable head or enlargement, whereby it may be operated.- The head of said operating'lever is located so that it will be adjacent to one of the fingers when the instrument is held in the hand in being used, and thus the same can be easily and quickly manipulated. It will thus be obvious that by pressing the said lever forward or backward the nibs can be brought together or separated, as desired, to control the flow of the paint through the same, and thus regulate the width of the line made by the instrument.

between two lugs e e, fastened to the interior of the case. The arm of the lever E, remote from that to which the operating-lever E is pivoted, is provided with an uprising portion c ,which is provided with an overhanging arm a. The said overhanging arm c is located over the perforation I) made in the nipple b and rests upon a part of the rubber tube 12 adjacent to said perforation. E indicates a spring secured at one end to thecase and having its other end arranged to bear upon the overhanging arm 2 to firmly hold the same in contact with the rubber tube, so as to close the said perforation in the nipple, and thereby prevent the passage of air. It will be obvious that by pressing downwardly upon the operating-lever E the overhanging arm 6 will be raised against the action of the spring E from contact with the rubber tube, so that the air which is maintained under pressure by a suitable air-forcing pump will lift the adjacent part of the rubber tube and will be free to escape outwardly through the nozzle for the purpose described.

It follows from the above construction that the operating-lever or thumb-piece E performs two functionsthat is to say, by presenting the same downwardly the air-blast is started, and then by either advancing or retracting said operating-lever the nibs or paintconductin g points will be separated or brought together, so as to regulate the quantity of paint which will be acted upon by the air-blast.
