FLUID-APPLY'IN'G MACHINE.
1,376,524. Specification of Letters Patent.
Application iiled August 20, 1919. Serial No. 318,729. To all 'whom z't may concern." l
Be it known that I, FREDERICK M. FURBER, a citizen of the United States, residin at Revere, in the county of Suffolk and tate of Massachusetts, have invented certain Improvements in F luid-Applying Machines, of which the following description, in connection with the accompanying drawings, is a speciiication, like reference characters on the drawings indicating like parts in the several figures.
The present invention relates to apparatus for applying fluids to various objects, it being particularly an improvement upon the machine invented by me, and patented in my name on July 29, 1919, under the Number 1,311,161.
The above-mentioned apparatus is especially designed for the application of such fluid stains as blacking to the edges of the soles of shoes, the fluid being sprayed from a nozzle against the work positioned horizontally beneath it by an edge-rest, preferably furnished by the supply conduit of the machine, and positioned vertically with/respect to its distance from the nozzle by a gage, which also serves as a guard to limit the application of the spray to the margin of the sole. It may be desirable to vary the width of this coated margin, and for this purpose it has been suggested that there be mounted about the supply conduit an eccentric sleeve, against the surface of which the edge of the sole operated upon may bear, the sleeve being adjusted as to angle to vary the projection of its wall beyond the conduit and therefore the distance of the work-guiding surface Jrom the gage. Such an arrangement is not entirely satisfactory, since, though the proper spacing may be obtained in one vertical plane, as directly opposite the nozzle, at each side of this the eccentricity will be different, and when the curved edge of the work is swung about the rest by the operator as he advances it beneath the nozzle, the width of the coated area will vary with the angle. An object of the invention is to provide means in a machine of this character, b which the width coated may be kept uni orm regardless of the manner in which the work is moved over it. I accomplish this result by positionvarying means upon which the work-surface to be sprayed is held spaced from the spraydelivering xmeans, this positioning means being movable in right lines toward and from the spray-delivering means and in a direction transverse to the spray deliver the position-varying means or rest prefrably maintains in its movement a symmetrical relation to the gage or guard previously mentioned. I have herein illustrated as `a rest a tube surrounding the supply conduit and being spaced therefrom, this tube being mounted in a guide which determines its movement of adjustment.
A further object of the invention is to effectively prevent the spray, especially after it has been broken up by contact with the work or guard, from being thrown into the air to be wasted, or to cause injury by being inhaled by the operator or by settlin upon surrounding objects. To this end, I have vspray-retaining means extending vfrom a point adjacent to the spray-delivering means into proximity with the receptacle from which the Huid is drawn and toward which the spray is delivered. To this retaining means may be connected a suction conduit. The flying drops of fluid, too finely divided to settle upon the body of fiuid in the receptacle, are drawn ofi' by the suction. The spray-retaining means preferably takes the form of a hood situated at the opposite side of the nozzle from the gage and partly surrounding the work-rest.
In the accompanying drawing is shown a particular embodiment of the invention,
ligure 1 being a broken side elevation; an
Fig. 2, a perspective view of the elements more closely connected with the present invention.
From a frame 10 projects an arm 12, in which is a passage delivering air under pressure to an outlet or blast tube 14 of an atomizing device carried bya vhead 16 supported at the outer extremity of the arm. Extending horizontally in the' head is a mixing passage 18, to which is connected a supply or suction conduit 20, shown as a vertical pipe mounted uponthe head and extending into a receptacle 22 :for the iuid which is to be applied. As the air current is discharged from the nozzle and through an opening 24: in the under side of the head alined with it, Huid is drawn, as is usual in atomizing devices, from the body contained within the' receptacle through a strainer 26 mounted upon the lower extremity of the supply pipe, it being here secured by' a set-screw 28 threaded through a boss at 1 ts upper` side. The fluid rising in the tube mingles with the air in the passage 18 and is ejected therefrom as a fine spray through the dehvery opening. At the outer side of the opening 24 is a gage-plate 30 fixed to the head 16, preferably by a screw 32 extending through a vertical slot in the plate and being threaded into the head. When a sole the margin of which is to be blacked is placed with its upper face against the lower edge of this gage, the distance of the surface from the delivery opening is fixed, and drops of fluid deflected after Contact with the work are retained by the gage, and their waste by falling upon central portions of the sole prevented. At the opposite side of the delivery opening from the gage is an edge-rest to position" the work transversely of the path of the spray. This rest is preferably in the form of a tube or sleeve 34 surrounding the supply pipe 20 and extending from the head just below the opening 24 down to a support 36, which encircles the lower portion of the pipe 20 and conveniently rests upon the boss of the strainer 26, it being here secured in place by a set-screw 38 threaded through its wall and engaging the pipe. At the upper end of the support, at opposite sides of a horizontal contact surface, are guideways 40, 40 extending substantially at right angles to the inner workengaging face of the gage 30 and equally spaced at opposite sides of the opening 24. In these ways is movably mounted a plate 42, to which the tube 34 is fixed. The support may be divided at one side, and through lugs adjacent to this division passes a screw 44, which may draw the walls of the support toward one another to clamp the plate 42 in its ways. The tube 84 is of greater internal diameter than the external diameter of the pipe 2O so that it is spaced therefrom. Consequently, when the screw 44 is loosened, the plate 42 may be slid in its ways to alter the distance between the gage-plate 30 and the adjacent side of the tube. There is, therefore, for such an adjustment a different marginal width of the sole inside the gage-plate subjected to the action of the spray, and, on account of the location of the ways with respect to the gage-plate and the delivery opening, the relation of the walls of the tube at opposite sides of the spray remains symmetrical, so that a sole turned in its advance, either in a clockwise or anti-clockwise direction about the rest, will receive a coating ofthe spray over the same width. y
lVhen the spray strikes the work and the inner face of the gage, the excess will be defiected in small drops, which, when thrown into the surrounding air, may be inhaled by cause damage. To prevent this in the machine hereinbefore mentioned, a conduit, through which a suction is maintained, has been connected to the upper wall 48 of the receptacle 22, this wall being inclined vdownwardly to a contracted central opening 50 about the supply pipe 20. 'It is found that though the heavier particles which would naturally be thrown down by gravity are effectively received by the opening 50, there is a considerable tendency for the finer misty portion, especially at the side away from the gage-plate or in the direction toward which the spray is deflected, to fioat beyond the receptacle so that it is not caught' by the suction. To prevent this, spray-retaining means is placed at the opposite side of the supply pipe and work-'rest tube from the gage-plate. This preferably consists of a hood 52, approximately semi-cylindrical in its horizontal contour and closed at the top by a portion 54 mer ing into the vertical wall by a curve 55. onnected to the hood is a suction conduit 56, which may also serve as a support for the hood. The suction through the conduit creates a current of air from the spray-applying area and at each side of the tube 34 within the hoodv 52. This may, by a proper strength of suction and positioning of the hood, be so proportioned that the fiuid particles thrown off from the work and plate 3() will be to a great extent drawn into and temporarily retained by the hood 52, the heavier portion being precipitated upon the wall 48 of the receptacle and ythrough the opening 50 to be taken up by the fluid body in the receptacle. A certain limited finer portion will be drawn into the conduit 56 and be carried Off by thel draft therethrough to be 'disposed of outside the room.
