SPECIFICATION forming part of Letters Patent No. 298,138, dated May 6,1884.

Application filed September 10, 1883. (Model.)

To all whom, it may concern.-

Be it known that I, LIBERTY WALKUP, a citizen of the United States, residing in the city of Rockford, in the county of Winnebago and State of Illinois, have invented a new and useful Improvement in Paint-Distributers, of which the following is a specification.

This invention relates to machines employed in the distribution of pigmentsin the art. of painting, but more especially in the fine arts.

The object of this invention is to produce a more efficient machine of its class in a more convenient and practical form; and it consists in the novel construction and arrangement of the parts, and in the mechanism employed as embodied in the accompanying drawings, all of which will be hereinafter more fully described.

In the accompanying drawings, Figure 1 is a plan view of a machine embodying my invention, and in which the operative parts are in their central position in the case. Fig. 2 is an under face view thereof. Fig. 3 is a plan view with the cover removed, and in which the operative parts are in their forward position. Fig. 4 is also a plan view with the cover removed, and in which the operative parts are Fig. 5 is a front edge view. h Fig. 6 is a front end View, in which the vertical air-tube and the pigmentreceptacle are shown in central section. Fig. 7 is a vertical central section of the wind-wheel and walking-beam. Fig. '8 is an isometrical rephand-piece is composed of a bottom, A, and

vertical edges B, in this instance of plate material produced in the box form represented, having its forward end portion, A, inclined rearward, and oblique or inclined to the horizontal plane of thehandle ,portion, having its rear edge, A on a higher plane. This forward inclined end portion is provided with a lid or cover, 0, made removable, or having a hinged connection with the upper edge of its 'cover.

rear vertical wall in a manner to permit it to open rearward to expose the working parts located within the forward section of the case. This hinged cover is provided toward its forward end with a crystal, a, through which the movement may be seen without opening the The handle portion of this case is provided with a cap, D, having a detachable or hinged connection with the vertical side walls thereof. The removal of this cap, in connection with the hinged cover when open, serves to expose the working parts contained within the case.

At It is represented a wind-wheel support, of bed-plate form, on which to support the main working parts of the machine. This bedplate is placed in the forward end f.,tl1'e case, and is connected to the bottom thereof by means of screws 1), passed through oblique slots [2, formed in the bottom of the case, and screw-threaded into the bed-plate in such a manner as to permit the plate to move endwise in the casein the direction of the slotopenings.

At 7) is represented a springwasher, placed under the head of one of I the screws b, on the outer side of the bottom plate of the case, to regulate the friction of the bed-plate on the bottom thereof.

At F is represented a wind-wheel composedsuitable foot-bearing in the bod-plate and in an adjustable screw-bearing in the free end of the overhanging arm 0, rising from the bedplate and overhanging the wheel on its upper .side.

At d is represented a vertical shaft,supp0rted to oscillate in a foot-bearing in the bedplate and in an adjustable screw-bearing in the free end of the overhanging arm (1, rising from the bed-plate and overhanging the upper end of the shaft.

' At 6 is represented a walking-beam fixed to the vertical shaft d, to oscillate-with the shaft. Both arms of this walkingbeam are slotted lengthwise, and its rear slotted arm extends IOO over the wind-wheel and receives the wrist of the crankshaft 0 thereof. The forward slotted 'arm of the walking-beam extends through a slot, c,formcd in the forward vertical end wall thereof, and immediately outside of the case receives the wrist or downturned end of the needle h.

At h is represented a guard-plate fixed to the forward vertical end wall of the casein the plane of the lower wall of theslot c,from which it extends forward to protect the forward free end of the walkingbeam projecting from the case over the plate. The vertical arm h of this plate extends lengthwise of the vertical end wall, and its inner face is reduced to form a vertical slot, 1', between it and the vertical end-wall of the case. This vertical slot i secures the wrist or inner end of the downturned arm oftheneedlch, depending through the slotted free arm of the walkingbeam, in such a manner as to permit a free reciprocating movement of the needle in the direction of its length. 7

At His represented a pigment receptaclein this instance of spoon formprovi(:led with an arm, 7:, extending rearward 011 the front edge of the case, having a pivotal connection therewith at 7.:'in amanner to permitits spoon portion to swing downward from the case. The rear edge of the spoon portion is provided with a lip-extension, (represented in dotted lines at 7n,) designed to engage an indentation in the edge portion of the case, to hold the spoon in connection therewith in a detachable manner, and in position thereon to receive the needle in its angle center.

At 1 is represented a finger, pivoted at one end to the vertical end wall of the case, and capable of a swinging movement in the vertical plane of theneedle, and having its free end forked to engage the needle when in its downtnrncd position, to hold it in the center of the receptacle to give direction to its reciprocating movements.

At 1 is represented anair-tube, supported on the bed-plate in such position relatively with wind-wheel that a current of air forced through its nozzle end will be delivered onto I the buckets of the wind-wheel to cause it to revolve. This air-tube is fitted with asinglewayeheclr-valve, 1,, to regulate the flow of air through the tube to the wind-wheel. This valve is fitted with a lever-arm, Z, projecting laterally from its upper end, having its free end portion extending through suitable open- 1ng in the free end of an arm, Z', fixed to the rear vertical wall of thecase in a manner to out points in the back-and-iorth movement of the bed-plate. This air-tube I is connected with a branch tube, m, by means of a flexible tube, K, in a manner not to interfere with the back-andforth movement of the bcd-plate.

At L is represented the main tube, a portion of which extends rearward through the case, andis designed to connect with the air-supply. The branch tube in connects with this main tube within the case, and receives the rear end of the flexible tube K.

At )1 is represented a branch of the main air-tube, which extends forward in the case and outward through the front edge thereof near its forward end, and its outer end is fitted with a vertical nozzle, at, opening centrally over the needle in front of the pigment-receptacle. The rear end portion, a, of the main tube, extending through the rear end of the case, is fitted in valve-seat form, as represented at n,consisting of a prominence projecting inward from one side of the tube, and an ex ternal opening on the opposite side thereof centrally over the prominence. This projecting end portion of the main tube is provided with a flexible tube, a, which extends over the external side opening in such a manner that when pressed into the side opening of the tube it will engage the prominence projecting inward from its opposite side, and close the passage and cut off the flow of airthrough the tube. The extreme outer end portion of the main air-tube L receives the end portion of a flexible tube, P, designed to connect with the air-su1')pl v.

At It is represented avalve-lcver placed within the case, having a pivotal connection at 0 with the bottom thereof. The rear end of this valve-lever extends outward through the rear end of the ease, and its projecting end,at o,is fitted to engage the flexible tube a over the side opening in the main air-tube L to press it against the prominence in the tube front side of the case, which is slotted to receive it in a manner to permit of a back-andforth movement of its free end in the lengthwise direction of the case. The inner end of this thumb-leveris pivoted at p to the for-- ward end of the valve lever in such a manner that its inward endwise movement will counteract the force of the spring 1) and open the valve.

Att is represented a connecting-link, having a pivotal connection of oneend, at t, with the bed-plate E. and a pivotal connection of its other end, at t, with the thumb-leverT near the center of its length, by which the backward and forward movement of the free end of the thumb-lever will impart an endwise back-and-forth movement of the bed-plate and of the several parts mounted thereon.

At a is represented a thumb-screw, having a screw-thread connection with the case at its forward. end, in such position that its inner end. will engage the bed-plate to limit its forward movement. By means of this thumbscrew the forward movement of the bed-plate may be regulated to limitit at any point within the limits of the devices.

At a is represented a rod fixed to the front edge of the case, and extending forward there-. of in position to be received in the left hand of the operator, to enable him to control the movements of the machine with greater certainty.

In the use of my improved paint-distributer, the main air-tube is connected with the air-supply. The pigment, in liquid form of a proper consistency, 15 then placed in the receptacle H. The valve 0 is then lifted from its seat by depressing the thumb-lever T, which permits a flow of air, under pressure, to pass through the branch pipe I- and impinge upon the buckets of the wind-wheel, causing it to revolve rapidly, and by reason of its crank and walking-beam connection will impart a rapid endwise-reciprocating movement to the needle connected with the walking beam. In this movement the needle, through the pigment contained in the receptacle, will, in its outward throws, carry with it a quantity of the pigment under the air-jet delivered from the vertical nozzle it, which 5 jet of air will disengage the pigment from the projecting end of the needle and deliver it in finely-divided particles or spray to any surface a proper distance below the needle. The quantity of pigment delivered at each outward throw of the needle and the character of work of which the machine is capable are dependent, mainly, upon the rapidity of the vibrations of the needle and the length of its throws. These, for the various kinds of work to which the machine is adapted, require that they be under the control of the operator, to be used at any point within the capacity of the devices. This I accomplish in my improved machine by means of the thumb-lever and its connection with the working parts, from which it wilhbe seen that with the thumblever in its rearward depressed position, as shown in Fig. 4, the check-valve t will be open to its greatest capacity to impart to the wheel its greatest velocity, and the relative-position of the wheel to the needle will be such as to impart to the needle its greatest throw and give to the machine its greatest capacity for the distribution of the largest quantity of the pigment. Vhen the thumb-lever is in its forward position, as shown in Fig. 3, if depressed to open the valvein the main tube, the checkvalve i will be in position to deliver 7 the smallest quantity of air to the wheel, to cause it to revolve at its lowest velocity; and the relative position of the wheel with the needle will be such as to impart to the needle its shortest throw and reduce the capacity of the machine for the distribution of the pigment to its lowest point. Between these extremes the machine, by means of the thumb-lever, is under thecomplete control of the operator, to regulate the distribution of the pigments as the'character of the work may require in the judgment of the operator.

I claim as my invention 1. In a paint-distributer, the hereindescribed case, consisting of a hand portion provided with a hinged or removable cover, and a forward end portion oblique to the hand portion,having a rearward inclination lengthwise and an upward lateral inclination from its front edge rearward, said inclined portion provided with a removable or hinged lid, sub stantially as and for the purpose set forth.
