STARCHlNG-MACHINE.

s C A o forming part of Letters Patent N 0. 680,559, dated August 13, 1901. Application filed December 26, 1899. Renewed J'anuaryl5, 1901. Serial No. 43,889. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM J. ASHER, a citizen of the United States, residing at vVillimantic, in the county of Windham and State of Connecticut, have invented an Improvement in Starching-Machines, of which the following is a specification.

My invention relates to an improvement in starching machines especially adapted to starching collars and cuffs. Difficulties of various kinds have heretofore been experienced in most machines of this class, and the object of my invention is to overcome these difficulties.

In carrying out my invention the collars, cuffs, or other goods are fed from a table upon the endless apron and between the same and another endless apron and over and between rollers and down through the vat or receptacle of hot starch mixture. As the goods emerge from the vat they pass over a roller similar to the first roller and beyond which the aprons separate. At the point of separation I place a roller wound with wire spirally in opposite direction from the center. This roller preferably travels faster than the apron and acts to spread out evenly the wet apron. The upper apron then passes between rubber rollers, which remove from the apron, by

a squeezing operation, all surplus starchy mixture. The apron then passes and meets the first apron and the two pass around the stretch-roller. per apron, from which the starchy mixture has been squeezed, comes in contact with the surface of the collars, ends, or similar articles and removes or, in other words, absorbs from the surface thereof the surplus starchy mixture. At this roller the aprons again separate, the upper one passing forward and the lower one rearward. The stretch-roller is adjustable, so that a tension may be applied to the upper apron,and I employ another stretchroller at the back end of the machine and over which the lower apron passes, which serves the additional purpose of allowing one of the rollers and the apron to be shifted, so that the collars and cuffs instead of passing to the rear of the machine to be removed by a second attendant may be caused to fall upon the upper apron and be carried forward to the attendant feeding the same into the machine.

At this meeting-point the up:

It is necessary to true the direction of both aprons as they pass through the machine and especially so before the same pass down into the vat of starchy mixture, because they are liable, as the result of their length, to move to either one side or the other of the machine. To rectify this movement of the aprons, I provide guide-cams upon shafts in bearings and rollers over which the aprons pass, which rollers act together with the guide-cams. The guide-cams and their shafts are in bearings, which at one side of the machine are simply pivots, while the bearings at the other side of the machine have a motion in line with the frame of the machine. I employ one of these devices for each of the aprons and they are located adjacent to where the aprons pass down into the vat of starchy material. The peculiar construction of these guide-cams and their operation are hereinafter more particularly described.

In the drawings, Figure l is a side elevation illustrating my improvement. Figs. 2 and 3 represent parts of the distant frame of the machine and the bearings of the guidecams. Fig. 4: is an elevation and partial section of exaggerated size looking from the back of the machine forward, so as to show one set of guide-cams, their shafts, and the adjacent parts of the machine. Fig. 5 is an elevation of the two guide-cams shown in Fig. 4:, their shafts being in section and the view showing the larger cam first and the smaller cam behind. Fig. (5 is a partial elevation and cross-section of the two shafts of the guidecams, their gears, and adjacent parts looking from the parts in Fig. 4 toward the righthand frame; and Fig. 7 is a view similar to Fig. 5, but with the guide-cams in the reverse position. In Figs. 5, 6, and 7 the parts are shown as of the same size as those in Fig. 4.

Power is communicated to the starchingmachine by the belt 2 and the fast and loose pulleys 4 5 on the shaft 6, and the belt 2 is moved to stop and start the machine by the belt-shifter The shaft 6 is in bearings 7 8 upon the frame of the machine, and the said shaft carries worm-wheels 9 10. These wormwheels mesh with worm-gears ll 12. (Shown by dotted lines in Fig. 1.) These are on the ends of the shafts of the main rollers a, a, and through the worm-wheels 9 10 and wormgears 11 12 and the rollers a a the aprons are driven and motion communicated to the other devices of the machine.

' Upon the shaft of the roller a is a spurgear 13. (Shown by dotted lines, Fig. 1, and full lines, Fig. 4:.) This gear meshes with a small spur-gear let on the shaft of the spreading-roller 15. The aprons c a pass over a portion of the surface of the main rollers a a, and I prefer to make the surface of the rollers a and a with spirally-arranged ribs, as shown in Fig. 4, as the same assists in evening the aprons.

In the sheet-metal vat m is placed the hot starch material or mixture, and in the vat, supported by suitable frames, are series of rollers 20 21, between and around which pass the endless aprons c c. Adjacent to the lower portion of the vat m I place a steamjacket 22 for the purpose of keeping the mixture hot, and the lower end of the vat is provided with a discharge-tube and valve 32, by means of which the contents of the vat can be removed.

The spreading-roller 15 is wound with wire spirally and closely in opposite directions from the center to the ends, and the same is caused to travel fasterthan the apron by the relative sizes of the spur-gears 13 14, and in this way the wet belt is spread out and evened as it passes around over the said roller 15. The rubber squeezing-rollers I) Z) are in suitable bearings upon adjustable bearing-boxes 25, capable of a certain extent of movement by means of a screw, (shown in Fig. 1,) and the bearings of the roller 1) are in levers 26, pi voted to the bearing-boxes 25, (shown in Fig. 1,) to the free ends of which levers some form of a Weight device is preferably connected, the action of the levers being to press the squeezing-rollers tightly together for the purpose of removing any surplus of starchy material from the upper apron c as the same passes between the said squeezing-rollers. The starchy material so removed falls upon the back of the apron cas the same descends into the vat.

The stretch-rollers d cl have hearings in movable frames, the said frames being connected to the screws 19', which screws may be turned by handles to feed the said frames nearer to or farther from one end of the machine. The bearings of the stretch-roller d are fixed in the frames, but the bearings of the stretch-roller d are in the form of jaws, into which the ends of the shaft of the roller are received. The apron 0 passes from the rubber rollers b b to and around the stretchroller 61, while the apron 0 passes from the main roller a to and under the surface of the stretch-roller d and then over the surface of the roller (1 and away to the rear of the machine over the stretch-roller 01 This stretchroller 61 is also in movable bearings operated by handles and screws 18. The special function of the roller (:1 is to stretch the apron c, the apron 0 being stretched by the stretchupon the frame of the machine.

roller d and adjusted at the bearing-boxes 25 of the squeezing-rollers.

The stretch-roller d may be moved considerably nearer to the machine, so as to slacken up the apron c sufficiently for the roller d to be lifted out of its bearing-jaws and placed in the jaws 24, which are in a plane forward of the bearings of the stretchroller d.

Each of the devices employed by me to return either one or both of the endless aprons into the proper path consists of rollers and guide-cams. e e represent the rollers, f f one pair of guide-cams, and g g the other pair of guide-cams. The guide-cams ff are upon shafts h h, and the guide-cams g g are upon shafts t' d. The respective ends of the shafts are received in bearing-boxes in suit able frames held in place by the action of springs.

The shafts h h have bearing-blocks 30 at their respective ends, and the shafts i t" have bearing-blocks 33 at their respective ends. One bearing-block 30 (see Fig. 3) is pivotally secured in an opening in the frame of the machine, while the other bearing-block 30 is in a frame which frame is provided with a downwardl y-extendin g portion carrying one end of the roller e, While the other end of'the roller e is carried in a pivot 31. (See Fig. 3.)

The bearing-block 33 at one end of the shafts 't' t" is pivotally held in a frame 70, which frame It is connected to a bracket portion of the main frame (see Fig. 2) by pivot-points, upon which the same may swing, and the lower end of the frame 70 has a bearing for one end of the roller e. The bearing-block 33 at the other end of the shafts i t" is pivotally held in a frame 75, which frame has a downward-extending portion, forminga bearing for the other end of the roller e.

Each of the frames k k is made with outward-extending arms having forked ends, which ends rest upon and straddle portions of the frame. The shafts h h'and M'are connected together by gears 27 28, and chains 29, passing around the shafts h and i, have their respective ends rigidly fastened to the frame of the machine. The frames 7.; and 70 are supported at the arms, which arms are forked and rest The f unction of the chains 29 and gears 27 and 28 will be hereinafter more fully described.

In the operation of the machine the collars, cuffs, and similar articles to be starched are placed upon a feed-table Z and are fed by an attendant between the aprons c c, where they come together adjacent to the feed-table and pass over the main roller a. The said articles are thencarried between the two aprons down into the vat of hot starch mixture and between the series of rollers 20 21 in a tortuous direction, and in transit the starch is thus worked through the aprons into the collars and cuffs, and as the aprons pass out of the vat they pass over the roller a and separate at the spreading-roller 15, the action of which,

as hereinbefore described, is to smooth out the upper apron as the same passes over said roller 15. The goods starched continue upon the apron 0 toward the stretch-roller (Z and the apron 0 passes forward around the roller 1) and between the same and the roller 1), which rollers squeeze the starch from the apron c and the surplus falls upon the back of the same apron, passing in the opposite direction around the rollers 19 and a down into the vat. The arrows indicate the direction of movement of the aprons and the various rollers, and after the apron passes around the roller bit passes rearward toward the stretch-roller d, and there meeting the starched goods absorbs from them the surplus starch as the goods and the two aprons pass beneath the roller d. The apron 0 passes around the roller cl and again forward over the roller 6 to the roller 19, and so again down into the "vat. The apron c continues upward over the roller d and rearward down to the roller d carrying the starched goods upon its surface and delivering the same to be removed at the roller 61 by an attendant. From the roller 61 the apron passes around a roller 34: and up over the roller 6, and at this point beneath the apron a drip-pan Z is provided for receiving any surplus starch that may fall from the surface of the apron c. The apron c then passes to and around. a roller I 35, adjacent to the main roller a, and so downward into the vat around the series of rollers 21 and up adjacent to the feed-table and over the roller 36 and thence to and around the main roller a to complete the operations. The functions of the squeezing-rollers b b and the spreading-roller 15 have been hereinbefore described, as well as the fact that each of the main rollers a and a has a spirallywound surface in opposite directions and performs the function of a spreading-roller. If it is desired to return the starched goods to the operator feeding the same into the machine, the screws 18 are rotated to slacken the apron c and bring the roller 61 toward the forward end of the machine. The roller d is then lifted out of its bearings and placed in the jaws 24, and the stretch-roller (Z is then moved by the screws rearward of the machine until the proper tension is brought to bear upon the apron c. In this position it will be seen that the starched goods do not continue upon the apron 0, but after passing around the roller (1 continue'forward upon the apron c, to be removed by the attendant who fed them into the machine.

It is to be remarked that the parts shown in Fig. 1 connected to the frame of the machine are duplicated upon the other side of the machine except where specially specified to the contrary. In connection with the guidecams and their shafts and bearings it will be noticed that these devices are similar, and a description of the parts specially shown in Fig. t will serve to describe the operation of both devices.

By reference to Figs. 4, 5, 6, and 7 it will be noticed that the shaft 77. carries the guidecam f and passes through the cam f and that the shaft h, which carries the cam f, passes through the cam f and that the cam f is smaller than the cam f to an extent equal in the diameter of the cam to twice the distance between the centers of the shafts h h, and the peculiar construction of the cams will be noted particularly from Figs. 4 and 5, and in Fig. 5 it will be seen that these cams are not a complete circle, but that a portion of the periphery for about one-quarter the circumference is of slightly less radius than the rest of the cam. It will also be noticed that the shafts h and h are connected by the gears 27 and 28, that the chain 29, passing around the shaft h, is connected thereto at a central point, with the ends of the chains fastened taut to portions of the frame of the machine; also, that the frame supports the block 30 at the right-hand end (looking from the rear of the machine) of the said shafts, and that the frame k at its lower end carries one bearing of the roller@ and is provided with arms forked at the ends to straddle portions of the frame that are inclined to a horizontal line. In the operation of this guiding device and for the purpose of illustration we will suppose that the apron c is running ofi to the right of Fig. 4 and strikes the guide-cam f, its edge coming between the edge of the cam and the roller e. This will cause the cam to move with the apron and roller and to rotate its shaft h and through the gears 27 and 28 to rotate the shaft h and the cam f in an opposite direction, and by the shape of the cam, as will be seen in Fig. 4, this rotation will tend to feed the apron toward the lefthand side of the machine over against the cam f, because the guide-roller 6 will thus be swung out of square with the machine. It will be noticed that as soon as the cam f turns in the direction of the arrow, Fig. 5, threequarters of a revolution the reduced periphery will cause the apron to pass free, and at this time the opposite edge of the apron will be adjacent to the guide-camf, the parts at this time occupying the position shown in Fig. 7. Should the apron then come into contact with the cam f, it will cause the same to rotate in the direction of the arrow, Fig. 7, turning its shaft and through the gears 27 and 28 the shaft h and the guide-cam f. The first movement produced by the apron coming into contact with the guide-cam f will through the intervention of the gears and the chain 29 impart a swinging movement to the frame 70 and the roller 6, moving the end of the roller nearest the point of vision in Fig. 1 toward the rearward part of the machine, so that the roller e will not be at right angles to the frame of the machine, but, swinging on the pivot 31, will occupy an angular position to the apron and frames of the machine, so as to feed the apron toward the opposite side of the machine in the direction of the guidetially as set forth.

cam f, and when the apron comes against the guide-cam f the conditions are reversed, so that the roller 6 swings toward the front portion of the machine to again cause the apron to travel toward the guide-cam f, the frame 70 meanwhile moving over the surface of the frame at the forked end of its arms. The apron guide or roller e, with the frame 70, has a similar motion and the guide-cams g g a similar action with their attendant parts, so that the apron o is treated bythese devices in the same manner as the apron c by the devices hereinbefore described. It is essential that the line of direction of the aprons be thus rectified before the aprons pass down into the .vat of hot starch mixture.

In my improved machine I have aimed to provide devices for thoroughly starching the collars, cuffs, and similar articles and to treat and deliver the same in the most convenient manner and to provide devices operating antomatically for the perfect and successful working of the various parts and functions of the machine.
