FEEDING DEVICE FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 228,918, dated June 15, 1880.

Application filed December 10, 1879.

To all whom it may concern Be it known that 1, JAMES H. MORLEY, of Holyoke, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Feeding Devices for Sewing-Machines, of which the following is a specification.

In sewing through several thicknesses of material with a sewing-machine having an ordinary feed-dog with a serrated face itis generally necessary to haste all the thicknesses of cloth together in order to prevent the under thickness from being fed forward more rapidly than the upper thicknesses,-and thereby causing the goods to pucker and draw.

The object of this invention is to render such basting unnecessary; and to this end the invention consists in a sewing-machine feed-dog having a serrated upper surface, and also having a pin or point projecting above its serrated upper surface of sufficient length to penetrate all or as many as may be desired of the several thicknesses of cloth to be sewed and bind them together as one thickness, which is fed forward by the serrated surface of the dog, the said pointed feed-pin being so connected with the feed-dog that it may be adjusted laterally with respect to the side edges of the latter for bringing the operating-point of the feed-pin in position to enter the holes in the cloth made by the needle and give the cloth the same appearance as a piece of ordinary goods.

In the accompanying drawings, Figure 1 represents an end view of a portion of a sewingmachine embodying my improvements, certain parts thereof being shown in section to better illustrate my invention. Fig. 2 represents a plan of a portion of the needle-plate and appurtenances of such machine. Fig. 3 repre sents a plan of the presser-foot, and Fig. 4. represents an elevation of the feed pin or point detached from the feed-dog.

Similar letters of reference designate corresponding parts in all the figures.

A designates a portion of the head of a sewin g-machine. B designates the sewing-needle, and O the presser-foot. D designates the work-plate or cloth-bed of the machine, and E designates a feed-dog having a serrated upper surface projecting upward through a slot in the plate. F designates a rotary cam, which acts upon the lever G to produce a longitudinal movement of the feed-dog, and F designates another rotary cam, which acts upon the feed-dog to produce its rise and fall. H designates a bell'crank lever, the end a of which engages with a lug, b, on the feed-dog and regulates the length of feed.

As the construction and operation of these several parts are exactly similar to like parts in many of the ordinary machines in common use, a more extended description of them is considered unnecessary.

In sewing several thicknesses of cloth upon such a machine it is always necessary to haste the several thicknesses together like one piece, which is readily fed forward by the serrated dog E. In order to dispense with such basting, I provide the feed-dog E with a pin or point, I, projecting from its upper surface above the serrations thereon, and adapted to be forced through the several thicknesses of cloth by the movement of the feed-dog to lock them together and enable thefeed-dog to feed them all forward by its serrated surface. The presser-foot O has init a slot, 0, for the accommodation of the pin-point. The pin I is composed of a shank, d, which is inserted in a hole of proper size in the upper surface of thefeeddog, and a point or prick, e, for penetrating the cloth formed eccentrically to said shank portion, as clearly shown in Fig. 4.

Many advantages result from forming the pointof the pin 1 eccentrically upon its shank. WVhen so constructed the pin may be turned in its hole to bring its operating-point in position to enter the holes in the cloth made by the needle and give it the same appearance as a piece of ordinary goods. In some machines it would also be difficult to bring the hole in the dog in line with the needle, as it would interfere with the shuttle, and the goods are lessliable to pull the pin from its hole in the dog when formed with an eccentric point for the reason that a pull upward causes said pin to bind more firmly in its hole. In some cases it might be desired to use only the pin I for feeding without the serrated face of the feeddog, and in such case I provide a false plate, J, adapted to be secured upon the work-plate or cloth-bed D, as clearly shown in Fig. 1.

This plate has in it holes or openings, through which the feed-dog and needle Work, and is of sufficient thickness to prevent the serrated face of the dog from coming above its upper surface, and hence the serrations of the dog are prevented from acting on the cloth. This plate also enables the point e of the pin I. to pass down farther below the goods in its return movement, thereby preventing it from dragging on the goods.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, with the serrated feeddog of a sewing-machine, of a pointed feedpin projecting above the face of the feed-dog and adjnstably connected therewith, substan- JAS. H. MORLEY.
