AIR-BRUSH ANIO SIMILAR APPARATUS.

Application filed May 13, 1916-.

1 0 all whom it may concern:

Be it known that I, HERMAN EDWARD Srfincnn, a citizen of the United States of America, residing at 220 Carroll street, Brooklyn, New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Air- Brushes and Similar Apparatus, of which the following is a specification.

This invention relates to improvements in means for regulating the flow and mixture of fluids, or mixtures of fluids and solids, and is particularly applicable for use in connection with apparatus in which a regulated stream passes through a nozzle or the like, as in spraying or atomizing devices; the invention relates moreparticularly to improvements in spraying or atomizing devices'and especially for the: air brushes or pistols which are employed in the art of painting or for like purposes in well-known manner; but while the invention is particularly applicable to the art of painting, and

a preferred embodiment of the invention as applied to this purpose will be hereinafter described. it is to be understood that the invention is equally of value in connection with all types of spraying or atomizing apparatus, and apparatus in which the mixture of two or more substances is regulated, as for instance, oxyacetylene blow-pipes and the like. 1

Among the objects of the invention are to provide improved means for regulating the mixture and flow of substances; to'pro-vide lmproved means for insuring a uniform atomizing effect; to provide a simple apparatus which, when once adjusted, can be operated by a simple movement of, a single operating member; and to provide a simple and inexpensive structure, the internal parts of wlnch are readily accessible for renewal, repair or adjustment.

A preferred embodiment of the invention as applied to a paintingtool or pistol will now be described with reference to the accompanying drawings, in which Figure 1 is a side elevation of the spraying tool.

Fig 2 is an end-elevation, looking in the direction of the arrow A of Fig. 1. Flg. 3 is a cross-section on line b?) of Fig. 2; and

Specification of Letters Patent. 7

tion' 1 in the manner shown.

Patented Feb. ii, ieia.

Serial No. 97,376.

Figs. 5 and (3 show diflerent positions of adjustment of the regulating means.

Referring to the drawings, it will be seen that the painting tool comprises a body portion 1 and a handle 2. The body portion is bored to provide a paint chamber 3 and an air chamber 4; threaded to the inner wall of the paint chamber 3 is paint nozzle 5, which in turn is surrounded by air nozzle 6, which latter nozzle is threaded to body por- An annular recess 7 is formed in the body portion between the nozzles 5 and 6, and forms with the inside wall of nozzle (3, an annular chamber 8 for apurpose hereinafiter explained.

' Air chamber 4 communicates with said annular chamber 8 by means of a passage 9 controlled by the air valve 10, which passage 9 leads into two passages 11 (Flg. 4)

leading to the bottom of annular recess 7.

Air is supplied to the air chamber 1 through flexible connections 12, connecting-piece 13, tube 14 in handle 2, and passage 15 in body 1. Paint is supplied to chamber 3 through the passage 16 to the Walls of which is at tached a paint-pot 17.

The flow of paint and air to the respective nozzles is controlled byv the paint valve 18 and the air valve 10. The valve 18 is mounting at its other end against an annular ring 26 connected to said valve stem'l9 by pin 27. The air valve 10' comprises a conical top 27' mounted on an octagonal guiding head 27 carried on stem 28 passing through bearing ring 29 and packed by a leather washer 30, which can be compressed by gland 31. A coil spring 32 bearing against ring 29 and the hexagonal guiding head normally maintains said air valve in closed position. Pivoted to lug 33 on the body 1 by pin 34: is-

a trigger 35 which is connected by means of a yoke piece 36 with a bifurcated valveaotuating member or plate 37, shown more clearly in Fig; 2, the arms of which embrace the valve rods 19 and 28. .It will be noted j that the outer or ear ends of these valve rods rot 19 and 28 are threaded at 38 and 39, and mounted on said ends are the milled regulating nuts or abutments 40, 41, and lock nuts 42, 43; said nuts 40 and 41 can be adjusted to various positions along the threaded ends 38 and 39 and the operation is such that on applying pressure to the trigger 35 and moving same toward handle 2, the slotted plate 37 will bear against said nuts 40 and 41 and thereby open the air and paint valves to the required extent. After the desired position of adjustment has been obtained, the lock nuts 42 and 43 are brought into position to maintain the nuts 40 and 41 against movement. As a result of the construction above described, a number of novel regulating effects may be had with the utmost ease of manipulation. For example, if it is desired to provide a maximum or substantially maximum opening for both paint and air, both regulating nuts can be screwed forward as far as possible to the left, as shown in Fig. 1, so that the fullworking stroke of the trigger 35 will be applied to the valve stems to cause said valves to open to their maximum extent. On the other hand, if it is desired to effect a minimum opening of the air and paint valves, the nuts can be adjusted toward the rear ends of the valve stems, as shown in Fig. 3, so that the first part of the stroke of the trigger 35 is ineffective and merely carries plate 37 into contact with theregulating nuts, which are moved only during the final portion of the. trigger stroke, thereby opening said valves only to the minimum extent. A range of adjustment between these described maximum and minimum openings of the valves can be had by intermediate positioning of the nuts 40, 41.

In addition to providing for a simultaneous range of adjustment for the two valve members, as described above, it is also possible by means of my regulating improvement to provide for independent adjustment of the valves in order that not only may the stroke of each valve difl'er one from the other, but also the timing relation of opening one valve as compared with the other. For example, as shown in Fig. 5, the air regulating nut 41 may be located in advance of the paint regulating nut 40, so

that during the first part of the stroke of trigger 35, the nut 41wil1be' carried toward the rear by the plate 37, thereby opening the air valvewithout opening the paint valve, so that the air can clear away any impediments which may exist in the aperture \of nozzle 6. Continued movement of the trigger causes the abutment of plate 35 against nut 40, thereby moving said nut toward the rear and opening the paint valve. It will be noted that the extent of opening of the air valve will be greater than that of the paint valve, owing to the fact that the airregulating nut is moved through a greater distance than the paint-regulating nut. It will be obvious that the paint valve might be opened before the air valve, and that any desired adjustment of the .extent of opening may be had without changing the timing relation between the operation of the two valves. 'For instance, as shown in Fig. 6, by screwing the nuts toward the rear ends of the threaded valve stems, with the position of the nut 41 relative to the nut 40 the same as that shown in Fig. 5, that is to say, with nut 41 in advance of nut 40, the timing operation will be the same as that described with reference to Fig. 4, but the extents of opening of the two valves will be lesser, as

only the latter portion of the stroke of trigger 35 will be effective to open the valves. It will therefore be appreciated that the invention provides a single operating member or trigger which, by a simple movement on the part of the operator, will always cause the tool to work with the adjustment to which it has been set, and the regulating means permit of numerous combinations of adjustments throughout all possible useful ranges.

It will be noted that the sides of the valve stems 19 and 28 are cut away at the rear ends, as -shown in Fig. 2, in order that they may fit into the rectangular slot in plate 37. This engagement between the two flat side faces of the valve rods and the fiat faces of the slot prevents any t'urningmovement of the valve stems which would otherwise occur were the nuts 40 and 41 to become rusted or stick to the threaded ends. It also assists in guiding the correct axial movement of the valve stems.

In order that the tool may bear. against the hand of the operator, a rest plate 44 is thence the air flows out through the nozzle 6, at the aperture of which it meets the paint issuing from the paint nozzle 5. It will be noted that the edge 45 of the nozzle 6 comes almost in contact with the edge 46 of the nozzle 5, thereby providing a restricted annular passage for the air and somewhat blocking the free flow of this air, so that when the air from the passages 11 flows into the chamber 8, it cannot all escape from said chamber at the point where it flows in, and as a consequence, some of said air flows into the upper part of said chamber and passes out evenly through the restricted annular opening between the'edges 45 and 46. lVere it not for the provision of this restricted annular opening, the air coming in through the passages 11 at the lower part of the nozzle would tend to flow out immediately and directly along the lower surface of the nozzle, and as a co equence, the paint issuing at the top part of the nozzle aperture would not be atomized as thoroughly as that issuing at the lower part of" the aperture. It will therefore be appreciated that the invention provides, for the even distribution of the air as it passes out from the nozzle, and a consequent even atomization of the paint.

Should it become desirable to renew or replace the valve stems 19 or 28, or to replace the springs 24 or 32, it is only necessary to rotate the yoke piece upwardly around the pin 47 which pivotally connects it with the trigger 35. The plate 37 is thereby disengaged from the valve stems; the bearing piece 22 is then unscrewed, after which the valvespring 19 and valve stem can be removed. The air valve can be removed by the simple expedient of unscrewing the gland 31.

It will be obvious that my improved apparatus is susceptible of considerable modification without departing from the spirit and the scope of the invention, and I wish it to be understood that the preferred embodiment described herein is ofiered by way of example only.
