STARCHING-IVIACHINE.

SPECIFICATION forming part of Letters Patent No. 505,282, dated September 19, 1893.

Application filed July 25. 1892. Serial No. 441,123. (No model.) i

To all whom it may concern:

Be it known that I, THOR A. THoRsEN, a citizen of the United States, residing at Chicago, in the county of Cook andState of Illinois, have invented a certain new and useful Improvement in Starching-Machines,of which the following is a specification.

In a starching machine embodying the principles of my invention I provide a bed or holder on which the article to be starched is placed, and a reciprocating stai-ching roll, by whlch arrangement, the starching roll can at one end of its stroke, take a suitable quantity of starch from a suitable source of supply, and in then passing back over the article, distribute the starch along the same. In order to provide for a more uniform distribution of starch I arrange between the starching roll and bed, a iiexible foraminous or open work sheet of textile or other suitable material, which said sheet is arranged to lie upon the article when the latter is in place upon the bed or holder. The starching roll is reciprocated so that it will traverse the sheet thus applied upon the article, and will while distributing the starch upon the sheet, force the starch through the same. By this arrangement I strain the starch, avoid its application to the article in a lumpy condition, and also regulate the quantity applied. The starching roll is held to its work with a yielding spring pressure so that it will conform to any irregularities in thickness in an article upon the bed and with a View of increasing the Working capacity of the machine, I may duplicate the foregoing describedV matters, as hereinafter fully setforth.

I also provide certain details of construction and arrangement constituting matters of furtherimprovement as hereinafter set forth.

In the accompanying drawings,-Figure l represents in elevation a starching machine embodying the principles of my invention. Fig. 2 is a vertical section through the same on line m-:r in Fig. l. Fig. 3 shows one of the starching rolls in cross section on a larger scale. Fig. 4 shows on an exaggerated scale atransverse section through a portion of the starching roll face, and Fig. 5 is a like view of a portion of the face of one of the beds. Fig. 6 represents in elevation one of the upper side portions of the machine. Fig. 7 isa section on line y-y in Fig. 6. Fig. 8 shows one of the end portions of the reciprocating starching roll carrier.

In said drawings, A indicates a trough or receptacle adapted for holding a suitable quantity of starch and supported by a main frame B comprising a couple of supporting sides or standards b arranged to position the starch receptacle at a convenient elevation. The starch receptacle is provided with a discharge pipe h having a suitable cock b2, and as a means for keeping the starch at a proper temperature and consistency I arrange within the starch receptacle a perforated steam pipe b3 which can be supplied from any convenient source of supply. VVhenevei-found necessary, the steam-supply can be let on, and steam introduced into the mass of starch, so as to warm and moisten the same.

The machine illustrated is provided with a. couple of reciprocating starching rolls so as to increase its working capacity, and to such end these rolls are attached to a reciprocating carrier C which may be operated by hand or other power, but which is more desirably operated by some suitable power driven mechanisin so as to insure rapid and steady work. The ends c of the reciprocatingcarrier are guided by Ways D arranged upon the mainframe of the machine, and as a simple, compact and convenient arrangement of driving mechanism, the carrier is reciprocated from crank-disks E by pitmen e,'and the crankdisks are iiXed upon a rotary shaft e which is driven from a driving shaft F by chain and sprocket connection or other suitable gearing. In the illustration presented, these two shafts are` respectively provided with sprockets e2 and f, and the shaft F which is conveniently arranged at the base of the machine is provided with ordinary fast and loose belt pulleys f2 and f3.

`With reference to certain further details in the construction ofthe carrier, its ends c are provided with studs carrying sleeves or anti-friction rolls c which traverse the guideways D so as to insure easy and steady work. Said ends of the carrier are also provided with bearings c2 for a rod c3 which connects said ends with one another and which pro- SoV IOO

vides upper journals for the pitmen. The starching rolls G are suspended from the carrier so that they may both dip into the starch when the carrier reaches the end of its down stroke, and in rising with the carrier, and after leaving the main supply of starch within the bottom portion of the starch rebeptacle apply the starch to such articles as may be placed upon beds H, arranged within the trough or receptacle A. Asamatter of course the starching rolls could be operated to starch such articles if the beds H Were arranged somewhathigher than shown but thiswouldinvolve a longer stroke on the part of the carrier so as to permit the rolls to dip into the starch, and a consequent loss of time, and hence, to render the device more simple, compact and rapid in operation, the beds H are arranged within and at opposite sides of the starch receptacle, whereby as soon as the rolls rise from the starch, they can begin the Work of applying the same to the articles on the beds.

In order to maintain the rolls against the articles with yielding pressure, I suspend the rolls from the carrier by springs or spring arms g and provide the carrier with cams or eccentrics g arranged to engage the springs and adapted for rotary adjustment so as to vary the degree of force with which the springs will hold the starching rolls up to their allotted work.

The sheets I of open work fabric or analogous flexible oraminous material are at their lower ends attached to the lower end portions ofthe beds H, and at their upper ends attached to rods t' arranged over the starch receptacle and disposed parallel with the starching rolls. These rods c' are removably supported upon walls or guard plates b4 which rise at the ends of the starching trough or receptacle. The rods also constitute supports for a cover K which may also rest upon ledges 'i2 on said guard-plates.

The beds 'H are at their upper portions hinged to slides or sliding tablesL upon which the articles to be starched can be laid preparatory to placing them upon the beds. The beds are brought into co-operative relationship with the rolls by adjusting the slides or tables toward the rolls, as in Fig. 2 wherein one table is shown adjusted in position to cause its alloted bed to hang in proper relationship to one of the starching rolls. In said figure, the remaining table is shown adj usted in position to draw its allotted bed away from the roll next adjacent thereto, and to'also so separate the bedfromits allotted strainer sheet I as to permit an article on the bed to be removed and another articletobe placed thereon.

The sliding tables are provided with angular wall sections or guard plates M having portions m which meet the wall portions b4 when the tables are moved toward the rolls, it being observed that the remaining portions m of said guard plates stand at right angles to said portions m, as will be understood by reference to Fig. l. The tables are also provided with latches or locking levers O by means of which they can be temporarily locked after being properly adjusted.

The carriers are desirably subject to balance springs P suspended from supports p on the guide-way standards CZ and at their lower ends attached to the ends of the carrier.

The faces of the starching rolls and beds are ribbed or corrugated and as a matter of further improvement I so corrugate the roll faces as to provide channels g2 having concaved side Walls as best shown at g3 Fig. 4, by which arrangement I provide the rolls With pockets for receiving and holding the starch in larger quantities, and parting with the same more gradually than could be attained by an ordinary groove or channel. 4

The ribs h of the bed-faces may be of any desired form, although I prefer making them V-shaped or serrated as best shown in Fig. 5.

The rear sides of the beds are provided with bumpers h which rest against the sides of the starch receptacle and permit the beds to be readily drawn up when the slides or tables L are drawn back.

The slides and beds can when desired be readily removed from the machine, and in such case the rods rcan be removed from the guards b4 which support them. y

With further reference to the flexible sheet I, it will be observed that it also constitutes an apron for holding the article to be starched upon the starching board H when the latter is in proper position relative to the roll. Said sheet may be of any suitable foraminous or IOO open Work material, and broadly considered as an apron for holding down the work under treatment, it will be noted that its openings serve as passages for passing the starch to the article, regardless of the size of mesh 'or openings; also that independently of its function as an apron for holding down the work, the sheet may be employed as a strainer, butsthat as a preferred arrangement, it serves both as a strainer, and as an apron for holding down the work.
