Specification of Letters Patent.

IlPatented. Aug. 15, 1905,

Application filed April 18, 1904. Serial No. 203,690.

To all whom it nuty concern.-

Be it known that ll, PAT lvlloltan UAvu, a citizen of the United dtates, residing at Charlotte, in the county of Mecklenburg and State of North Carolina, have invented a new and use :ful titarching-lvlachinc, of which the following is a specification.

The invention relates to improvements in starching-machines.

The object of the present invention is to i inprove the construction of starehing-machines and to provide a simple and comparatively inexpensive one, capable after collars, cuffs, and other small articles are fed into it of starching the same, wiping the superfluous starch from the articles, and depositing the articles upon a table or other receptacle.

Another object of the invention is to provide a starching-machine in which the articles will be effectually prevented from adhering to and winding around the wiping-rolls.

liurthermore, the invention has for i ts object to enable this mechanism to be readily removed from the starclrpan to permit the latter to be conveniently cleaned.

With these and other objectsin view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, size, and minor details of construction within the scope of the claims may be resorted to Without departing from the spirit or sacrificing any of the advantages of the invention.

in the drawings, Figure 1 a side elevation of a starchinganachine constructed in accordance with this invention, the starching mechanism. being shown in operative position in full lines and swung backward in dotted lines. Fig. 2 is an end elevation of the same. Fig. 3 is a longitudinal sectional view on the line 3 3 of Fig. 2. Fig. t is a transverse sectional view on the line at l of Fig. 1. Fig. 5 is a detail sectional View on the line 5 5 of Fig. 1. Fig. 6 is a detail view ilh'istrating the manner of yieldably mounting the large roll or drum and the lower rolls. Fig. 'Tis an enlarged detail view illustrating the construction of the sectional bearings and the means for holding the springs in position.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates an approximately semlcylindrical starch pan or receptacle constructed of sheet metal or other suitable material and se cured to and supported by an approximately rectangular frame 2. The main frame 2 consists of corner-posts or uprights 3, connected at their upper ends and lower portions by horizontal bars at.

The starching-pan 1, which is supported by the upper side bars 1-, is provided with suitable inlet and outlet pipes 5 and 6. The collars, cuffs. and other articles are fed into the machine at the front thereof and are carried through the starch by upper and lower endless carriers, con sisting of upper and lower endless aprons and rolls. The endless aprons, which may, if desired, consist of solid belts, are preferably composed of tapes or cords 7 and 8, arranged at in tervals, as shown. The upper endless carrier has a large roll 9, which is preferably provided with annular grooves 10 to receive the cords 7 and which is mounted on a shaft 11.. The shaft 11 is mounted in slidable bearings 12, consisting of suitable boxes arranged in guides 18 of the sides let of a hinged frame which carries the starching mechanism and which is adapted to be swung into and out of the starch pan or receptacle. Each side let consists of an upper straight portion or bar and a lower approximately semicircular portion 15. The top portion is provided with upwardly-extending arms forming guides and connected by a plate or piece 16. Coiled springs 17 are interposed between the plates or pieces and the journal-boxes 12 for yieldably holding the large upper roll 9 in contact witha curved series of lower rolls 18. The coiled springs are preferably supported at their upper per-- tions by belts or screws 19, which pierce the plates 16 and which prevent the coiled. springs from becoming displaced. The sides 14. of the hinged frame are pivoted or hinged to the main frame 2 by a rod or pintle 20, which pierces the side bars 4 of the main frame. The hinged frame is adapted to be swung backward from the position illustrated in full lines in Fig. 1 of the drawings to that illustrated in dotted lines to afford access to the starching-pan, whereby the same may be readily cleaned.

The lower rolls 18, which are smaller than the upper roll 9, extend around the bottom of the same and are preferably corrugated, as shown, and are provided also with annular grooves 21 to receive lower endless cords. The corrugations are adapted to carry a sup ply of starch upward, whereby the articles will be thoroughly starched. These lower rolls are provided with suitable journals 22, which are arranged in suitable bearings of the lower curved portion of the sides of the hinged frame. The front portions of the sides are connected by transverse rods 23 and the lower portions are connected by rods 24, located between the rolls, as shown.

In order that the lower rolls 18 may bear uniformly against the upper drum or roll 9, the curved lower portion 15 of the hinged frame is provided with radial slots or openings 40, in which are slidably arranged sectional bearing-boxes 41 for the reception of the journals of the lower rolls. The curved lower portion of the sides of the hinged frame are provided at opposite sides of the slots or openings eiO with projecting portions or arms L2, which are spaced apart to extend the said slots or openings and which are connected at their outer ends by plates 43, suitably secured to the arms. The sectional bearing-boxes are engaged by coiled springs i4, interposed between the plates 43 and the said boxes and supported in the spaces between the arms 42 by screws 45 or other suitable fastening means. 'By this construction the lower rolls are held against the drum or large upper roll 9 and the articles passing through the machine are thoroughly saturated with starch, and the lower rolls are adapted to yield to inequalities in the thickness of the articles operated on.

The articles after leaving the rolls 9 and 18 are carried upward by the endless aprons to a pair of wiping- rolls 25 and 26, which have padded peripheries and are adapted to remove the superfluous starch from the collars, cuffs, and other articles. The superfluous starch drips back into the starching-pan, and the articles are carried from the wiping-rolls by the endless aprons, which extend beyond the said rolls, being supported by guide rolls or idlers 27 and 28 of less diameter than the wiping-rolls and spaced apart to spread the adjacent stretches of the endless aprons. By this construction the articles are prevented from adhering to and being wound around the wiping-rolls and are delivered upon a suitable table. (Not shown.) This construction also obviates the necessity of removing the articles from the machine by hand.

The Wiping-rolls and the guide-rolls, which are provided with annular grooves to receive the cords, are supported by standards 29, and the latter are secured by bolts 30 or other suitable fastening devices to the sides of the hinged frame. If flat tapes or a continuous belt is used, the annular grooves of the rolls will be unnecessary, as will be readily understood. The standards have forwardly inclined upper portions 31 and are provided with rearwardly-inclined angularly-bent arms 32. The lower guide-roll 28 is journaled in suitable bearings of the arms 32. The arms 31 are provided with longitudinal slots 33 to receive the bearings 34 of the upper wipingroll, which is yieldably held. in engagement with the lower wiping-roll by coiled springs 35, engaging the bearings or boxes 3t of the upper wiping-roll. The lower wiping-roll is journaled in suitable bearings or boxes 36, arranged at the lower ends of the longitudinal slots 33. The longitudinal slots 33 extend to the upper ends of the standards, and the sides of the slotted portions are connected by end plates 37, against which the upper ends of the coiled springs bear, the coiled springs 35 being held against displacement by suitable fas-' toning devices 38, which pierce the plates 3'7 and extend into the upper ends of the springs. The journal boxes or bearings 34 are provided with rearwardlyextending arms 39, which are provided with bearings for the reception of the journals of the upper guideroll 27, the latter being movable upward and downward with the upper wiping-roll to maintain the upper endless apron at substantially the same tension.

The shaft of the large roll 9 is extended at one side of the machine and is provided with fast and loose pulleys to receive a suitable drive-belt for operating the machine. The lower stretch of the upper endless apron and the upper stretch of the lower endless apron are contiguous from the front lower roll 18 to the wiping-rolls, and they gradually diverge as they leave the latter and extend beyond the same, whereby the articles are prevented from adhering to and winding around the wipingrolls, and are positivelydischarged at the rear end of the machine.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A machine of the class described, comprising a receptacle, and upper and lower carriers composed of upper and lower endless aprons, a large upper roll receiving the upper endless apron and extending into the receptacle, a curved series of lower rolls arranged contiguous to the large roll and receiving the lower endless apron, upper and lower wiping-rolls located in rear of the said rolls and receiving the said endless aprons, the upper wiping-roll being yieldably mounted and movable toward and from the lower wiping-roll and upper and lower guide-rolls located beyond the wiping-rolls and receiving the endless aprons, the upper guide-roll being carried by the yieldable wiping-roll in its movement to and from the lower wiping-roll said guide-rolls being spaced apart to separate the endless aprons, substantially as described.

2. A machine of the class described, comprising amain frame, ahinged frame provided with opposite standards having slotted upper portions, said standards being also provided with projecting arms, upper and lower endless carriers composed of endless aprons, rolls arranged contiguous to each other and receiv- 'reasaa bearings slidable on the upper portions of the standards, upper and lower wlping-rolls mounted on the standards, the upper wiping roll being arranged in the slidable bearings, upper and lower guide-rolls, one of the guiderolls being mounted on the said arms, and the other being carried by the slidable bearings, and upper and lower endless carriers arranged on the rolls, substantially as described.

In testimony that I. claim the foregoing as my own I have hereto ai'lixed my signature in the presence of two witnesses.
