FOLDING AND CREASING MACHINE.

SPECIFICATION forming part of Letters Patent No. 623,882, dated April 25, 1899.

Application filed June 11,1898. Serial No. 683,160. (No model.)

To all whom it may concern:

Be it known that we, JOHN F. CAMERON and JAMES A. CAMERON, of the city of New York,

liminary to the subsequent process of stitching.

The invention consists of the novel features which will be hereinafter described, and pointed out in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specificati on, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of our machine. Fig. 2 is a side elevation of the knife used for nicking the edge of the cloth after it has been folded and creased, parts being in section on the line 2 2 in Fig. 3. Fig. 3 is a sectional side elevation on the line 3 3 in Fig.

' f of the upper portion of our machine; and

Fig. 4 is a top plan view of the same, parts being broken-away and in section.

This machine is designed to take a bolt of cloth and to turn both edges over simultaneously, so as to form the folds necessary for hemstitching the edges thereof, and to cut one edge, so that it may be torn into designated lengths.

Upon a suitable frame A is mounted a bar H, which has. curved slots H formed in one edge thereof and adapted to receive the edges of the handkerchief-stock J, so as to roll the stock back upon itself and commence the fold which is to form the hem. The stock is usually obtained in bolts, which are in practice placed on any suitable support beneath the machine. The stock J passes upward with its edges in the slots H and is then received by the folders g, mounted upon an inclined plate or table G. These folders are placed at such a distance apart as to accommodate the majority of the widths of handkerchiefs desired. The handkerchief-stock after passing the first folder g enters a second folder g,which, turning under the edge of the stock, completes the fold.

The inclined plate or table G is provided with a large recess. G, lying between the folders. This recess permits the surplus stock to drop down, and thus enables the device to be used without adjustment for material of different widths. The folders or guides 9 should be placed a distance apart which will accommodate the narrowest width desired to be handled by the machine. The surplus of stock of greater width will drop into the recess between the folders. The stock after passing the folders g and g is then received by rollers which compress the fold or crease it. These rollers comprise an under roller C which extends entirely beneath the stock, and the two short upper rollers B which engage the edge only of the stock and are movable vertically, so as to release the stock when desired.

The roller C is mounted upon a shaft C which extends through sleeves C and bearings C upon the frame A. Upon one end of the shaft C is mounted a pulley O or other suitable means by which it may be revolved. The rollers B are upon shafts B which extend through sleeves B and bearings B on the frame A. The bearings B are pivoted upon horizontal pivots in ears a, mounted upon the bearings C. This enables the shaft B and the roller carried thereby to be swung upward, so as to release the handkerchiefstock when desired, or to be swung downward, so as to firmly engage the stock. This is done by the following means: Links D are connected to each side of the sleeves B and at their lower ends are connected to levers E, fulcrumed upon lugs D, extending downward from the sleeves C. The levers are held against displacement by means of notches cl, which receive the lower ends of the lugs D.

To the levers E are connected rods E,which extend downward and connect with the ends of a cross-bar F, which is connected to a treadle F. This treadle is thrown upward, so as to raise the rollers B by means of a spring F and is lowered, so as to engage the handkerchief -stock between the rollers B and C by depressing the treadle by the foot. The handkerchief-stock in passing between these rollers has the hem or fold pressed downward, so that it will afterward retain its shape.

At the farther side of the rollers is a curved plate l,whieh receives the handkerchief-stock and conveys it downward to a table A, which is located a short distance below the rollers, which table extends outward for a convenient distance. Upon its upper surface, at the side next to one of the operators, is a scale M, laid off with the position of the knife K as a base. This knife K is pivoted upon apivotK,located at the edge of the table, and works in conjunction with a plate N, placed upon the table at the edge of a slot to therein. To the'lower arm K of the knife is connected a rod or link L, which at its lower end is connected with a treadle L. Depressing the treadle will depress the knife, and thus nick the edge of the hand kerchief-stock J. This knife is of such length as to extend over the fold J, which forms the hem. The stock is then torn the rest of the distance, so as to insure following the threads of the material.

In cutting the stock up into separate handkerchiefs the measurement is done by hand, the stock being pushed to an adjustable crosspiece and one edge nicked by the knife K. Two operators are required for running this machine, one to attend to the proper fitting of the stock and the other to cutting the same. The open space lying between the folders or guides g and g and the open space lying between the upper rollers B permit the machi no to be used withoutadjustment for stock of considerable variation in width. If the machine is properly adjusted for handling the narrower stock, it will handle the wider stock without adjustment, as the surplus material will simply bunch up in the center. This it may do, as the upper rollers do not extend entirely over the stock, and consequently engage only the fold or hem.

The folders gand g are removable and may be replaced by others which will form hems of different widths. The folders g are also shown as being adjustable, each being provided with an arm having a longitudinal slot receiving a binding-screw Having thus fully described our invention, we claim as new and desire to secure by Letters Patent- 1. Ahandkerehief folding andcreasingmachine, comprising folding-guides adapted to engage and fold the side edges of the handkerchief-stock, a supporting-plate which is cut away between the guides, permitting the center .of the handkerchief-stoek to drop between them, and rollers adapted to engage and compress the folded edges of the stock, substantially as described.

2. A handkerchief folding and creasing machine, comprising folding-guides adapted to engage and fold the edges of the stock, rollers adapted to engage and compress the folds, and means for separating said rollers to release the stock, said folding-guides being separated by an open space which permits the slack of the stock to drop down between them, and the com pressing-rollers which engage one side surface of the stock, contacting therewith only at the folded edges, substantially as described.

3. A handkerchief folding and creasing machine, comprising guides adapted to engage and fold the side edges of the stock, a supporting-plate which is cut away between the guides, permitting the center of the stock to drop down between them, rollers adapted to engage and compress the folded edges of the stock, and means for moving the upper set of rollers vertically to free the stock, substantially as described.

4. A handkerchief folding and creasing machine, comprising guides adapted to engage and fold the side edges of the stoek,'a supporting-plate which is cut away between the guides, a single roller extending beneath the stock, two separate short rollers engaging the upper side of the folds at the edges of the stock, bearings for said rollers, which bearings are pivoted so as to swing the rollers upward, and means for controlling the position of the rollers, substantially as described.

5. A handkerchief folding and creasing machine, comprising guides engaging and folding the edges of the handkerchief-stock, a supporting-plate therefor cut away between the folding-guides, a single roller extending beneath the stock, two separate short rollers engaging the upper side of the fold at the edges of the stock, said upper rollers having pivoted bearings permitting their upward swing, springs acting to hold said rollers in one direction, and a treadle acting in opposition to said springs, substantially as described.

6. A handkerchief folding and creasing machine, comprising a bar having inwardlycurving slots therein adapted to receive the edges of the handkerchief-stock to give it a preliminary fold, an inclined plate adjacent thereto, having folding-guides thereon and being cut away between the guides, and feed and compressing rollers receiving the stock from said plate, the upper rollers engaging only the folded edges of the stock, substantially as described.
