16 Claims.

This invention relates generally to starching machines and more specifically to an improved starching machine adapted particularly for use in starching portions of shirts and other laundered articles, the predominant object of the invention being to provide a machine of this type which is of improved construction and arrangement, and because of such improved construction and arrangement is capable of performing its intended function in a more efficient manner than did starching machines heretofore known and used.

starching machines such as that disclosed herein are employed in laundries which cater to the public, and in carrying on the business of such organizations speed in performing various operations required in laundering and finishing articles is of the utmost importance. Prior to this invention various starching machines have been employed in public laundries and while most of these starching machines functioned with a fair degree of success they were deficient in one respect in that it was necessary'that the operator give complete attention to each article during the entire time it was being acted on by the starching machine. Obviously this situation had the efiect of slowing up the starching operations for the reason that the operator of the starching machine could not turn from the starching machine to select another article and prepare it for starching until the starching machine had completed the operation of starching the preceding article. In other words, these earlier starching machines were so operated that the operator had to give his entire attention to the articles being starched throughout the entire period of time during which the articles were being starched with the aid of the machines, and could not select another article and'prepare it for the starching operation until the starching of the preceding article by the machine had been completed. Thus after each starching operation of these earlier machines the machines came to rest and remained inactive while another article was being prepared for the machine.

The predominant feature of the improved machine disclosed herein is that the machine, during operation, does not require the entire attention of the operator, and therefore as soon as the operator has introduced an article into the machine and has set the machine in motion, he may turn his attention to the task of preparing another article for the machine. By the time an article passing through the machine is discharged therefrom preparation of a succeeding article for the machine is completed and this article is immediately introduced into the machine and passes therethrough while the operator is preparing still another article for the starching operation. It is plain, therefore, that the rest periods of the earlier starching machines, when articles were being prepared for introduction into the machines, are entirely eliminated in the use of the machine of the present invention andtherefore the time required for starching a given number of articles with the aid of the improved machine disclosed herein is substantially less than was required to starch the same number of articles with the aid of the earlier starching machines.

Referring now to the drawings, wherein is shown for the purpose of illustration, merely, one embodiment of the invention, l designates the frame of the machine which may be of any suitable construction and arrangement to perform its function of supporting the various parts of the machine. The frame I supports at its top a plate 2 which is provided with a depressed portion that provides a reservoir 3 in which a body of starch solution is received. At the right-hand side of the machine as shown in Fig. 1, a channelway 4 is formed in the top plate 2 which communicates with the reservoir 3, said channel-way being closed at its outer end by an inclined wall 4'. Disposed immediately beneath the reservoir 3 is a heating apparatus which includes an electrical heating element which, in the use of the machine, serves to maintain the starch solution at the proper temperature.

At the right-hand end of the machine as Viewed in Fig. 1, the frame of the machine includes upright elements 6 which are suitably secured together and to the main portion of the frame of the machine to provide a support for 'a wringer l which constitutes an important part of the machine. The wringer 1 includes a wringer frame 8 which includes a vertical portion 9 (Fig.

4), an overhanging top portion I0, and a (18 'the instrumentality of a transmission belt 39 'wh'ichoperates over pulleys 40 and 4! fixedly pending portion II which extends downwardly from an end of the overhanging portion ID. The

frame of the wringer 1 is completed by a portion 12 which is alined vertically-with the depending frame portion I I but is spaced from said depend-- ing frame portion to provide an opening 13 which leads into the wringer frame. The wringer frame 8 is suitably secured in place with respect to the upright elements 6 of the frame of the machine. "The ioverhanging 'portion 10, the depending portion. H, and a 'part'of the vertical portion 9 ofth'e wringer frame are produced. by spaced therewith a piston rod l9 which extends downwardly through an opening formed in the bottom wall of the cylinder, said piston rod being extended through a packing sleeve 20.

Arranged'for vertical movement with respect to the wringer frame 8 is an inverted U-shaped member 2| which serves as a support for the top roller 22' of the wringer; The member 2| is guided by and moves vertically between the'spaced apart. elements of theiwringer frame portions 9,

l0, and II, and the shaft 23 of the upper roller 22 is supported forrotation at its opposite ends in bearings formed in the opposed downwardly extended legs of the member 2| The'member 2| is supported by opposed "coil springs 24 -which are attached at their. lower ends by means of eye bolts 25 to said member 2|; and at their upper ends'by means of similar eye bolts 26 tothe top walls of hollow elements 2'l which are supported by the overhanging portion ID of the wringer frame. As shown in Fig. 8' the hollow elements are provided with base-portions 21 which span the spaced "apart 1 elements of the overhanging portion ll] of the'wringer frame, and said base portions are suitably secured to said spaced'apart elements; The'piston rod l9 is provided with a lower'extension IQ of reduced diameter which extends into an opening 2| formedin the top portion of the member 2|. 1 The wringer of the improved machine includes also .a lower roller 28, the shaft 29 of which is supported forrotation'inbearings 30 supported by opposed portionsof the wringer frame. The lower roller 28 of the wringeris disposed immediately above the; channel-way 4 previously mentioned herein and fixedly mounted on the shaft 29 of sai d lower roller'at an endfof said lower rollerat an endiof saidshaft is asprpCket wheel 31. l enating overjt-he sprocket wheel 3| is a sprocket chain 32, said sprocket chain'serving to transmit rotary-motion to the sprocket wheel 3!, and to the shaft 29 and lower roller 28 a s c a ed mounted respectively on the shaft 31 and the shaft 42 of the motor 38.

The improved starching machine disclosed herein includes an arm 43 which is of paramount importance. This arm is shaped as shown to the best advantage in Fig. 1, said arm being supported for pivotal movement by a pivot 44 which pivotally. attaches'said arm to 'a'vertically dispo'sed' element 44' forming a part of the frame of the machine. As illustrated in Fig. 1 the arm comprises an upper portion 43a and a tail portion 43b which passes beneath the top plate 2 of the machine through an opening 45 formed through an end plate 46 of the machine. The upper portion andthe tail portion of the arm 43 are shown in' the drawings as being separate elements'secured together by bolts 41 but obviously the entire arm may be made in one piece. At its forward end the arm 43 is provided with a head 48"of substantial width (Fig. 8) which generally is of substantially L-shaped formation in cross-section as shown in Fig. 1. Preferably this head is provided with spaced ribs 48' as shown by dotted" lines in Fig. 8 which extend forwardly from the downturned rear wall of the head to the forward edge of said head. These ribs tend to prevent splashing asthe head of the arm is lowered forcibly into the starch solution in the reserv0ir3'as will-be hereinafter explained. The "tail portion'43b of the arm 43 has mounted thereon, as shown to the best advantage in Figs. 1, 6, ahd'l, a mercury switch 49 which is electrically connected to a source of electrical energy and to the'motor'38. Also said tail portion of said arm hasattached thereto a rod 50 which is provided with a bifurcated portion 5| that embraces the tail portion of the arm,

said rod being pivotally connected to the tail 55 is a coil spring 51 and interposed between the bottom face of the sleeve 53 and the nut 56 is a coil spring 58. Because of the'arrangement just described it is obvious that the sleeve is supported for yielding sliding'movement on the rod 50.

'Secured by welding, or otherwise, to angle elements 59 forming parts of the frame of the machine is a vertical'eleme-nt 60 (Fig. 3) which is provided with a boss'B'I, and pivotally attached to said boss by means of a 'bo-lt 62 is a member 63 (Figs. 4 and 8). At one of its ends the member 63 is bifurcated as shown at 64 in'Fig. 8, and the spaced legs of this bifurcated portion 64 ill are provided with alined apertures which receive the trunnions 54 of the sleeve 53, and. at its opposite end said member 63 is bifurcated as shown at 65. The member 63 has secured thereto an arm 66 which extends parallel with said member and is projected outwardly beyond the bifurcated end 64 of said member, as shown to good advantage in Fig. 8. Pivotally attached to the member 63 at a point inwardly of the bifurcated end portion 64 thereof is a link 61 (Fig. 4) and pivotally attached. to said member 33 at the bifurcated end 65 thereof is a similar link 68. The links 61 and 68 are pivotally attached at their lower ends to valve rods 69 and It which 1 extend into an air valve housing H which is secured to the vertical element 3!] previously mentioned herein. The housing H contains suitable air valve mechanism of common construction which is not shown, and leading into this housing from a source of air supply is an air inlet conduit 12. From the opposite side of the housing H an air outlet conduit 14 leads to the top of the air cylinder l5. Preferably the air valve housing has a mufiler 15 associated therewith to suppress the noise of exhausted air during operation of the machine.

' passed through the opening Coupled to the shaft 35 by means of the coupler 16 (Fig. 4) is a shaft 11, said shaft I! being supported for rotation by suitable bearings 18 supported by portions of the frame of the machine. The shaft H has fixedly mounted thereon a sprocket wheel 19 over which a sprocket chain 89 operates (Fig. 1), said sprocket chain operating also over a sprocket wheel 8| which is mounted on a shaft 82. The shaft 82 is supported for rotation by bearings 83 supported by portions of the frame of the machine. Certain links of the sprocket chain 80 have projections 84 formed thereon which serve a function to be hereinafter set forth.

In order to control movement of the arm 43 and retain it in positions to which it is moved the tail portion 43b of said arm extends between a pair of spaced plates 85 (Figs. 1 and 5). The plates are secured at their upper ends to a part of the frame of the machine and at the lower ends of said plates a headed rod 86 is associated therewith. The rod 86 is extended through alined apertures formed in the plates with the head of the rod contacting with one of the plates. Interposed between the other plate and a nut 81 is an expansible coil spring 88 which in an obvious manner forces the lower ends of the plates toward each other and thereby causes the plates to frictionally grip the tail portion of the arm 43 located between said plates whereby the tail portion of the arm will be retained in various positions to which it is moved.

In the operation of the improved starching machine disclosed herein a body of starch solution is arranged in the reservoir 3 and the operator of the machines folds a shirt, for instance, so that the collar and cuffs to be starched are arranged together. The body of the shirt is l3 to locate said shirt portion between the rollers of the wringer and with the collar and cuffs of the shirt extended into the starch solution in the reservoir 3. The arm 43 is then moved downwardly by the operator to the position in which said arm is shown in Fig. 9 and when so positioned the head 48 of the arm maintains the collar and cuffs of the shirt in a submerged condition in the starch solution. When the arm 43 is depressed the valve mechanism within the valve housing H is opened by movement of the member 63, links 31 and 68, and rods 39 and I0, and compressed air will pass through the conduit 14 to the air cylinder Hi to move the piston l8 downwardly within said air cylinder and lower the upper roller of the wringer against the action of the coil springs 24. As the roller reaches its lowered position electrical contact is made by the mercury switch 49, due to the tipping thereof as the tail portion 43b of the arm 43 is moved downwardly, and the motor 38 is set in operation. This results in the lower roller of the wringer being rotated through operation of the belt 39, shaft 31, speed reducing gearing within the housing 36, shaft 35, and sprocket chain 32. The rotating wringer rollers will draw the shirt to the right in Fig. 9 thereby drawing the portions of the shirt submerged in the starch solution from beneath the head 48 of the arm 43 and eventually the portions of the shirt that were submerged in the starch solution will pass between the rollers of the wringer when the excess starch solution will be squeezed therefrom, the starch solution so squeezed from the shirt portions falling in the channel-way and returning to the body of solution in the reservoir 3.

The machine is so timed that immediately as the shirt is entirely discharged from. between the rollers of the wringer one of the extensions 84 carried by the sprocket chain 83 will contact with the extended end of the arm 66 fixed to the member 53 and carry said extended end of said arm upwardly. This will restore the member 63 to the position it occupied before it was moved on its pivot 52 by depression of the arm 43 and as a result of such restoring movement of the member 63 the valve mechanism within the housing H will be closed to simultaneously shut off passage of air to the cylinder l6 and permit air in the cylinder and conduit 14 to be exhausted through the muffler 15 when the coil springs 24 return the upper wringer roller to its elevated position. Such restoring movement of the member 53 also raises the arm 43 and thereby breaks the electrical circuit leading to the motor 38.

From the foregoing it is plain that all an operator of the machine need do is to fold the shirt and insert the folded shirt in the machine so that the collar and cuffs are submerge-d in the starch solution and the body of the shirt is 10- cated between the rollers of the wringer of the machine. With his hand the operator then depresses the arm 43 so that the head 48 of said arm retains the collar and cuffs of the shirt in a submerged condition in the starch solution. Upon depression of the arm 43 the operator sets the machine in motion, and immediately upon depressing the arm 43 the operator may turn from the machine, as it no longer requires his attention, and prepare the next shirt for the machine. Thus the machine is practically in continuous operation as a succeeding shirt is inserted in the machine as soon as the preceding shirt has been discharged therefrom.

Because of the opposed coil springs 24 of the wringer of the machine the top roller 22 of said wringer may tip if the article passing between the rollers happens to be thicker at one side of the roller than at the opposite side thereof. In this event one of the coil springs 24 will stretch more than the other coil spring. The fit between the extension I9 on the piston rod I9 and the aperture 2 I in the upper portion of the member 2| is loose enough to permit such tipping of the upper rollerof the wringer.

By referring to Figs. 1, 8, and 9 it will be noted that the head 48 of the arm 43 is provided with an upstanding extension 48a. This extension serves as a guard which largely eliminates the likelihood that an operators hand might be accidentally inserted between the rollers of the wringer of the machine as the operator is working at the machine.
