4 Claims.

garment subject to perspiration with water and,

a chamois, also may be successfully employed for removing chemicals used in laundering garments to remove rust, grease and other kinds of spots.

Another object ofthis invention is the Provision of a device of the character specified which will be compact, durable and economical to manufacture and will permit a person not necessarily skilled in the art to efilciently and rapidly spot garments as above stated without the danger oi injury to the fabrics of the garments through the use of water and air under pressure and independently controlled so that the water may be passed through the garments within a selected area thereof and then blow the water therefrom, eliminating any possibility of water marks appearing in the fabrics of the garments after the operation has been completed.

With these and other ob'jects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of our invention, reference is to be had to the following description and accompanying drawings. in which- Figure 1 is a side elevation illustrating a garment spotting machine constructed in accordance with our invention.

Figure 2 is a vertical sectional view illustrating the machine.

Figure 3 is a sectional view taken on the line 3-3 of Figure 1.

Figure 8 illustrates the control valve positioned for admitting air under pressure to the garment and for exhausting air `from the cylinder of the machine.

Figure 9 is a detail sectional view illustrating the other control valve positioned toadmit water to the bottom of the cylinder. l f

Figure 10 is a diagrammatical view illustrating the connections between the valve and the cylinder and the spray head or nozzle.

Figure 11 is a view similar to Figure 10 showing the valve positioned to admit water to the bottom of the cylinder and to exhaust air from the upper end of the cylinder and to admit air under pressure to the spray head or nozzle.

Referring in detail to the drawings, the niimeral 5 indicates .a base and rising vertically therefrom is a hollow standard 6 terminating into a substantially conical shaped basin 1, the upper edge of which forms a rest 8 for a portion of a garment, the remaining portion of the garment may be supported by a table 9 carried by the basin 1, as clearly shown in Figures l and 2. The table 9 adjacent its rear edge is provided with an elongated vertically arranged guard, It, to prevent the garments from coming in contact with the working parts of' the device. The portion of the garment to be treated is located over the basin with the garment resting on the edge 8 of the basin as specified.

The basin adjacent to the edge 8 is provided with an internal shoulder to form a seat il for the support oi a metallic ioraminous'disc I2 acting as a support for the fabric of the garment arranged over the basin.

The standard 6 being hollow provides a drain for the basin and the lower end of said standard may be connected to a sewer. or the like.

A reinforcing plate I3 is integral with the standard 6, basin 1 and base 5 and is provided with an oiTset portion il acting as a fulcrum for a frame ii, the latter being pivoted on the portion i4, as shown at II. The frame i5 is of such a construction as to have mounted therein an inverted hood Il, the lower edge of which is coactive with the edge I of the basin in clamping the garment onto the basin with a portion ofthe fabric of the garment overlying the foraminous disc I2.

The frame I5 has a curvature thereto which allows said frame to swing freely over the guard on the table and also integral with the frame is adjustable thereon a counterbalance weight i8, the purpose of which lis to facilitate the raising and lowering of the frame and the hood carried thereby. A suitable handle I9 is provided on the front portion of the frame to permit the operator to raise and lower the hood Il with respect to the basin 1. The raising and lowering of the hood by the operator is assisted by the counterbalance weight I8.

A latch arm 20 is pivotally connected to the frame I and is coactive with a, keeper 2l formed on the reinforcing plate I3 in releasably securing the hood I1 in engagement with the basin 1. The latch arm is equipped with a beveled face 22 to facilitate the latch arm riding over the keeper 2I so that the latter may engage with the shouldered portion of the latch arm.

A coil spring 23 is connected to the latch arm 23 to retain the latter in riding engagement with the keeper 2l.

A spring iniiuenced foot lever 24 is pivotally mounted on the base, as shown at 25, and is of substantially L shape. The standard 6 is provided with a slot 26 to allow the treadle portion, indicated by the character 21, to operate cnteriorly oi the standard and directly over the base 5. The L-shaped foot lever has riding contact with the beveled face 22 of the latch arm so that by depressing the treadle portion the latch arm may be disengaged from the keeper 2| to free the frame for pivotal movement in an upward direction. When the frame I5 is swung downwardly to bring the hood I1 in operating relation to the basin 1, the latch arm moves into engagement with the keeper 2I and releasably secures the hood I1 in the specified position.

Integral with the upper portion of the hood I1 is a cylinder 2B provided with intake and

exhaust ports

29 and 30. lA suitable passageway is provided between the hood I1 and the lower end of the cylinder 28 and is provided with a stuiling gland 29' to slidably receive a stem 3d of a piston 3l slidable in said cylinder. The: upper end of the cylinder is provided with a removable head 32. A groove 33 is provided in the wall of the cylinder 28 between the exhaust port 3Q and the bottom wall of the cylinder ior the purpose of permitting iluid to by-pass to the exhaust port as the piston moves past the exhaust port or in substantial alignment therewith. This will allow any fluid trapped in the lower portion of the cylinder by the downward movement of the piston with respect to the exhaust port to gradually escape therefrom, consequently providing a uid cushion for the piston as it nears the limit oi its downward stroke.

The stuing gland 28' prevents fluid leakage between the cylinder and the hood I'i. The lower end of the stem of the piston 3i has detachably connected thereto a spray nozzle or head 34 located within a substantially inverted funnel shaped member 35. The lower end of the stem 30 has a passage 36 opening into the spray nozzle or head 34 and also connects with a port in the substantially funnel shaped member 35 to which a itting 31 is adapted. The tting 3l cle-p tachably connects to the passage 36 a flexible pipe 38 which passes from the hood Il by way ci an opening and has an air tight connection therewith by a suitable packing 38.

A cushioning spring I1' engages with the top vwall of the hood I1 and surrounds the stein iti of the piston, the spring I1 being oi the coiled conical type so as to trictionally engage with the a rearwardly extending balance arm I5' having stem 30'. 'I'he purpose of the spring I1' is to cushion the upward movement of the piston 3l in the cylinder 28.

A manually actuated control valve mechanism 40 is suitably mounted on the cylinder 28 and includes a housing 4i chambered to rotatably receive a plug type valve element 42 provided with an operating handle 43. The valve element 42 is provided with Y-

shaped passages

44 and 45 rendering the valve mechanism 4u of a double twoway valve arrangement. The housing 4I is provided with intake ports 44 and 45'. Also the housing 44 is provided with

exhaust ports

46 and 41 and is further provided with

outlet ports

48, 49, and 50. The outlet por't 48 is of elongated formation and has connected thereto a ilexible pipe 38 by a tting 53. The housing 4I has an outlet port bil to which is connected a pipe 55 by one oi the fittings 53. A pipe 5S is connected to the outlet port E@ by a tting 53. The pipes 38, et md b@ are preferably iiexible. The pipe 55 connects with the intake port 29 of the cylinder while the pipe E@ connects with the exhaust port 363 ci said cylinder. The inlet port 44 is connected to an air pressure supply (not shown) by a pipe 553, while the inlet port 45 is connected to a water pressure supply by a pipe 6I. The port 43 connects with the outlet port 49 as distinctly shown. in Figure 10.

The valve element 42 is provided with arcuately curved passages 52 and 63.

The valve element 42 has a cutoff position and two on positions or operative positions. The valve element d2 may be ni'oved into any of the stated positions by actuating the handle 43. When the valve element is in one of its on positions the passage 4 thereof connects the

ports

44 and 54 and the passage 45 connects the passages 45 and de, also connects the curved passage 63 with the ports 4l and 50. The valve element when in this position will-allow air under pressure from the source to flow into the upper end of the cylinder 2B and act on the piston 3| to drive the same downwardly bringing the substantially funnel shaped member 35 in close proximity to the portion of the garment overlying the foraminous disc l2 and gripped by the hood I1 and the basin l and at the same time water under pressure from the water source will iiow to the spray nozzle or head 34 and from the latter through the fabric oi the garment positioned over the foraminous disc. The water under pressure passing through the fabric of the garment will remove perspiration therefrom or perspiration marks or stains. At thisposition of the valve element 42 the lower end of the cylinder is open to the exhaust port il so that any fluid in the lower portion of the cylinder may escape.

The valve element 42 when moved into its other operative position connects the pesage 44 with tm port et and the port 44' also the passage d@ will be positioned to connect the port 45 with the port tu. The valve element 42 when in the -latter-named operative position will then permit air from the air supply source to ilow to the spray nornle or head and water from the water supply to the bottom oi the cylinder for forcing the piston Si upwardly. The air under pressure escaping irom the nozzle or head will completely fill the hood il and pass through the fabric of the garment overlying the oraminous disc and drive the wai/er from the fabric so that when the fabric dries it will be free from water marks or stairs. it the time that the water enters the icwer portion of the cylinder the passage 62

conthe passages

44 and 45 thereof do not communicate With any of the ports of the housing, 4l.

In operation, the operator elevates the hood Il and then arranges the selected portion of the garment over the foraminous disc I2. The hood l1 is then lowered to grip the garment or press a portion of the fabric of the garment against the edges of the basin. The valve mechanism is then operated so that air under pressure will force the piston downwardly bringing the spray nozzle or head 34 closer to the fabric to be treated and at the same time admit water under pressure to the spray nozzle for action on the selected area of the fabric so as to cleanse the latter of perspiration or perspiration stains.

After this operation has been carried out for aselected length of time, the valve mechanism is operated to admit fluid to the lower portion of the cylinder to force the piston 3| upwardly and at the same time admit air pressure to the nozzle for driving from the fabric the water used in Washing said fabric so that when the fabric dries it will be free of Water marks or stains. This same operation is carried out for washing from the fabric chemicals or the like used in removing rust, grease or similar spots.

Thus it will be seen thatl a very efficient machine has been provided for water spotting selected areas of a garment and which may be successfully operated by persons not necessarily skilled in the art of spotting garments.

The type of work above specified may be rapidly and safely carried out without danger of damage to the faerie of the garment-and eliminates the present practice of hand washing of the garment or the washing of the entire garment as frequently done.

While we have shown and described the preferred embodiment of our invention, it will be understood that minor changes in construction. combination and arrangement of parts may be made Without departing from the spirit and scope of the invention as claimed.
