STITCH [NDENTING AND SEPARATING MACHINE.

SPECIFICATION forming part of Letters Patent No. 602,859, dated April 26, 1898.

Application filed June 22, 1896. Serial No. 596A99. (No model.) Patented in England October 1, 1895,1l'0. 18,309, and in Germany May 28, 1896, No. 57,941.

To all whom, it wrong concern:

Be it known that 1, JOB LEE, engineer, a subject of the Queen of Great Britain, residing at 15 Gladstone street, Kettering, England, have invented certain new and useful Improvements in Stitch Indentin g and Separating "\Iachines, (for which I have received Letters Patent in Great Britain, No. 18,309, dated October 1, 1895, and in Germany, No. 57,941, dated May 28, 1896,) of which the following is a specification.

This invention has reference to an improved constructionof stitch indenting and separating machine, sometimes termed stitchpricking machine, employed to throw up and separate, and thereby render more distinct, the stitches in the soles and waists of boots and shoes.

The invention will be fully understood from the following description in reference to the accompanying drawings, wherein- Figure l is a vertical section of a stitch indenting and separating machine constructed in accordance with this invention, and Fig. 2 a section of the indenting and stitch-separating tool.

A represents the standard or pillar of the machine, A a table at the upper end thereof, and A two cheeks fixed at one end of the table and between which is a guideway having therein a sliding or vibrating bar B, having secured or otherwise rigidly attached thereto or formed therewith a dull-edged blade or device B for indenting and separating the stitches in the waists and fore parts of boots and shoes, as hereinafter described. The bar by preference works in the angular position shown and has on one side apin B which enters a slot 0 in a link 0, the lower horizontal extension 0 of which is passed over a vertical rod D and connected thereto by screw nuts D D A spring D also encircles the rod and is compressible between the lower nut D and the upper face of thetable A. The said rod has a double-hooked lower end, to which are connected two springs D D attached also to another similarly-constructed rod D, fastened at D to a treadle-lever E, f ulcrumed between two lugs E on the exterior of the pedestal A.

A screw-bolt A passes through the two cheeks A to connect them together, and also through a slot 0 in the link G, and acts as a guide-pin to the latter and insures its vertical movement.

On the pin B may be a tappet or an antifriction-roller B which when the machine is in operation is maintained in contact with the peripheral edge of a cam F, mounted on a shaft F, on the end of which are the usual variable-speed driving-pulleys. (Not shown in the drawings.)

The action of the machine is as follows: The edge of the sole is held under the indenting and separating blade or device by the operator, who at the same time depresses the treadle E by his foot, thereby lowering the connecting-rods D D, link C, and bar B, so that the roller 13 on the latter is moved into contact with and rides on the edge of the cam F, the shape of which is arranged to raise the bar B and its attached blade B at each revolution and then suddenly, with the assistance of the springs D D to lower it, the said springs being stronger than the spring D so that when put under tension by operating the treadle they will overcome the resistance of spring 1) and compress the same. This vibrating action of the bar B and blade B will be continued so long as the treadle remains depressed, as described, and the vibrations of the said barmay be accelerated or retarded by shifting the driving'belt, as will be well understood, from or to one or other of the speedpulleys hereinbefore referred to. While the bar and blade are being vibrated,as described, the operator holds the sole of the boot or shoe under the said blade and moves it along the desired distance after each descent of and indentation made by the said blade. Upon the operator removing his foot from the treadle the springs D D D recover their normal condition and raise the antifriction-roller 13 out of the path of the cam F and the vibrating bar and blade become quiescent.

The invention is not confined to the particular connective mechanism shown and described between the vibrating bar and the treadle-lever, as. it is obvious that the detail of this may be readily varied within the skill of the mechanic. lhe bar 13 may also be arranged at any other angle and the cam F may be constructed to impart more or less fall to the bar and its attached blade, if desired.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is-- 1. In a machine of the character described, the combination with a vibrating bar, and a stitch-separating tool carried by said bar, of a treadle lever, a yielding connection between the latter and the vibrating bar whereby a downward movement of the treadle-lever the combination with a vibrating bar and an causes a similar movement of the bar but permits a movement of the latter in an opposite direction independently of the treadle-lever, a rotatable cam adapted to operate the vibrating bar as long as the treadle-lever is de pressed to positively move the bar upwardly at each rotation of said cam and a spring applied and arranged to move and hold the said bar out of action when the treadle is released.

2. In a machine of the character described, the combination with a vibrating bar, and a stitch-separating tool carried thereby, of a treadle-lever, a link having a slot-and-pin connection with the vibrating bar, a yielding connection between the link; and treadle-lever, a rotatable cam operating to vibrate the bar, and a spring arranged to move and hold the said bar and tool out of action when the treadle is released in the manner and for the purpose specified.

3. In a machine of the character described, the combination with a vibrating bar, and a stitch-separating tool carried thereby, of a link'having a slot-and-pin connection with the bar, a rotatable cam operating to vibrate the bar as described, a treadle-lever, a yielding connection between the latter and the link, and a spring operating to raise the link and remove the bar out of operative relation 5 with the cam when the treadle-lever is raised,

all as and for the purpose specified.

4. In a machine of the character described,

indenting or separating tool carried thereby, of a cam for moving said bar in one direction, a treadle and spring connection between the same and said bar for holding the latter to its operatingcam, the arrangement being such that said spring connection is put under tension by operating the treadle, and a spring for moving and holding the bar beyond the range of action of the cam when the treadle is released.

In witness'whereof I have hereunto set my hand in the presence of the two subscribing witnesses.

J OB LEE.
