SAMUEL e. nosimnn, or nrcnmonn HILL, NEW Yomfil I SPRAYING DEVICE.

Application filed March 3, 1926. Serial No. 91,957.

V This invention relates to improvements in spraying devices, and has particular reference to the provision of means for spraying garments to facilitate pressing of the same.

In the manufacture of garments such as responding parts throughout the several views.-

In carrying out the invention, my novel spraying device includes a flexible conduit or couphng 10, a manually operated valve 11, a p

shirts, underwear, and other articles of cotto ."channeled member 12, and a spray nozzle 13. I goods, it is necessary that they be presse These parts may preferably be arranged as afterforination, in order to'be presentable for sales and display purposes. Such press- 0 ing is usually done with hand'irons, and the shown in 1, the flexible conduit or coupling 10 be ng connected to a liquid supply pipe 14 which is conveniently arranged ad- '60 articles must be moistened before pressing, jacent to a pressing table, of any ordinary as is well known to those skilled in the art. I

propose to spray the garments with water, whereby the time required for the moistening operationis much less than for the hand sponging operation, with the additional ad vantage that better work may be obtained.

One object of the invention is to provide a spraying device particularly adapted for use 0 in connection with pressing garments, which will be flexibly mounted above or adjacent to the pressing table whereby a spray of water or other liquid may be applied in different directions so as to evenly spray the whole-gar- 5 ment regardless of-its size or shape.

Another object is to provide such a device with a flexible support which will be resilient so as to return to its normal position out of the Way of the presser when it is released.

1 Another: object is to provide such a device which will lie-simple in construction, strong and durable in service, efficient in'operation, and an improvement in the art. n

With these and other objects in view, the

i invention resides in the novel features of construction, combination, and arrangement of parts hereinafter set forth, illustrated in the accompanying drawings, and specifically pointed out in the appended claims.

1 In the accompanying drawings, wherein Y a preferred embodiment of the invention is shown by way of illustration, I

or preferred type, upon which the garment 16 to be pressed is spread out.

Iprefer to make use of a valve of the type shown, which comprises a body portion 17 having an annular valve seat 18, and laterally extending inlet and

outlet ports

19 and 20 respectively, said ports communicating with opposite sides of the valve seat. The lower portion 21 of the valve body 17 is preferably 7 of an enlar ed diameter, and fitted with a screw threa ed closure plug 22 having a bore 23 serving as a guide for a stem 24 of a valve 25, A'coxnpression spring 26 is disposed between the upper side ofthe plug 22 and an an- 'nular shoulder 27 on the lower'side of Valve 25, whereby to force the valve against the valve seat 18, andin order to provide a tight sealing, the valve 25 preferably carries on its upper side a disc 28 of rubber, fiber, or other suitable composition material to contact with the seat 18. The disc 28 may be held in place by a screw 29 or othr fastening means. The upper portion of the valve .body 17 is formed 3 with a threaded bore 30in alinement' with the valve seat 18, and into which is screwed a centrally operated plug 31 which cooperates with a packing gland 32 to maintain compressible packing 33. For the purpose of operating the valve 25 against the action of the spring 26, a. plunger 34 is slidable through the

members

31 and 32, the lower end of said plunger contacting the head ofthe screw 29, and the up- -per end extending beyond the gland 32 for engagement by a lever 35 which is pivoted at 36 to a bifurcated extension 37 of the valve body 17. Thus by depression-of the lever 35,

i lowingthe water or other fluid:t0.pass from l Similar reference characters designate corthe inlet port 19 to the outlet port 20. ml

have a suitable degree of resiliency, I may surround it with a helical sprin 38. Water or other spraying fluid is supplied through the conduit 14 and flexible coupling 10 to the inlet port 19. The. water is under pressure varying in accordance witlnlocal working conditions, good results havmg been obtained with pressures ranging from 60 to 80 pounds per square inch.

The outlet port extends through a stem 39 which supports the sinuously channeled member 12 having a plurality of reversely disposed passages 40 connected together at their ends as clearly shown at 41 in Fig. 2, and terminating in a dowm trd direction as at 42.

A nipple 43 is carried by the member 12 in alinement with the passage-42, for the connection of the spraying nozzle 13, which-comprises a hollow shell or cap 44 internally threaded at 45. A deflector 46 is adjustably mounted within the threaded portion of the shell-44, and is provided with diagonal passages 47 at opposite sides of its periphery, and may have a stem 48 to facilitate its assembly and adjustment in the shell 44. The outer wall 49 of the shell 44 is relatively thin and preferably tapering toward its center where a small opening 50 is formed, the wall material at the edge of the opening being practically a knife edge.

As water or other spraying fluid enters the shell 44 from the nipple 43 it strikes the deflector 46 and is forced through the diagonal passages 47 against theouter wall 49. By virtue of the angular disposition of the passages 47 and the taper of the inner surface of the wall I 49 the whirling motion of the fluid is greatly increased, and this, coupled with the passage through the restricted opening 50, effectively breaks up the stream and produces a fine spray which diverges from the nozzle. The angular divergence. of the spray may be varied by adjusting the deflector longitudinally in the shell 44, lowering the position of the deflector being effective to widen the spray.

In use, the device is mounted as shown in Fig. 1, the normal position of the partsbeing substantially as shown in full lines in this view. The garment 16 to be pressed is'properly spread out upon the table 15, whereupon the operator grasps the body 21 of the valve 11 between the thumb and fingers of one hand with the palm of the hand overlying thehandle 35. The device is then moved, by flex-ure of the coupling 10, to the dotted. line position, after which the handle 35 is depressed to open the valve and permit the passage of water through the sinuously channeled member and nozzle. In carrying out the operation, the

device may be moved laterally, or in fact, in any direction necessary, thus insuring the spraying of any garment regardless of variations in size or shape. \Vhen the garment has been completely sprayed, the device is released, and it automatically returns to its normal, substantially upright position, under the action of the spring 38, and because of such position and the presence of member 12, a volume of liquid remains between the valve. and the nozzle. After the device has returned to its inoperative position as in Fig. 1, the nozzle is at the highest point in the system, and therefore there will be no after-drip from it, and the entrapped volume of liquid remaining between the valve 11 and the nozzle 13 results in practically instantaneous pro- -jection of a spray in the next operation so that a high efliciency is obtained.

From the foregoing it will be evident that I have provided a spraying device simple in construction, and efiicient in operation. lVhile I have described the device as being particularly adapted for spraying garments, I do not limitmyself to such use, since it may beadapted with equal advantage to other purposes. The invention is susceptible of modification and I reserve the right to make such changes as fall within the scope of the appended claims. without departing from the spirit of the; invention.

Having thus described my invention, what I claim is:

1. Ina spraying device of the class described, the combination with a vertically fixed conduit, of a flexible, resilient, conduit in communication at one end with the upper end of the fixed conduit, andadapted by its resilience to normally stand in a substantially vertical position, and. a spray nozzle positioned on the other end of the resilient conduit so thatjt will be at substantially the highest point in the conduit when the device is inoperative.

2. In a spraying device of the class described, the combination with a vertically fixed conduit for fluid, of a flexible, resilient, conduit in communication at one end with the upper end of the fixed conduit, and adapted by its resilience to normally stand in a substantially vertical position, the resilient con- 'duit comprising a length of flexible tubing enclosed by a helical spring wound thereon, a third conduit communicatingwith the other end of the resilient conduit and provided with a manually controlled valve, and a spray nozzle positioned on the third eonduit so that it will be at substantially the highest point in the conduit when the device 1 is inoperative.
