HEINRICH THEODORE REUTERMANN, OF SAN ANTONIO, TEXAS.
EYELET-HOLE ATTACHMENT FOR SEWING-MACHINES.
.SPECIFICATION forming part of Letters Patent No. 574,451, dated January 5, 1897. Application filed September 2, 1892. Serial No. 444,903. (No model.)
.To {.Z/l whom. t ntttf/ concer/t:
Be it known that I, HEINRICH THEODOEE REUTERMANN, a citizen 0f the United States, residing at San Antonio, in the county of Bexar and State of Texas, have invented a new and useful Eyelet-Hole Attachment for Sewing-Machines, of which the following is a speoication.
My invention relates to improvements in eyelet apparatus which is screwed to the presser-bar and operates by the movements of the needle-bar of a sewing-machine.
The object of my invention is to con struct a simple and perfect eyelet apparatus which can be attached to any sewing-machine. I attain this object by the mechanism illustrated in the accompanying drawings, in which- Figure l is a top View of the entire apparatus. Fig. 2 is a side view of the same, and lhig. 3 is a vertical section on the line X X of ig. I.
Similar letters refer to similar parts throughout the several views.
The block A is shaped in such a form as to fit the presser-bar of a sewing-machine, and it requires only to be screwed to the saine to attach the apparatus to a sewing-machine.
t The letter B designates the actuating-lever, which is loosely fitted on shaft U, so that its slot ZJ shall be engaged by the screw, whereby the needle is secured to the needle-bar. To the shaft Uis also loosely tted a plate O, carrying a pin c, the end of which is adapted to operate in a radial slot b2, formed in the lever B. The movement of the pin c in the slot b2 is limited by a regulating-screw b3. To the pin c is tted a pawl which is adapted to engage a'ratchet-wheel D, fixed to shaft II. The aforesaid pawl is held in contact with the teeth of the ratchet-wheel by means of a spring, as usual in such mechanism. To the shaft Uis also fixed a beveled cog-wheel E, which inserts its teeth into a similar beveled cog-wheel F. This beveled cog-wheel F is united underneath with a plain cog-Wheel G, which turns horizontally in base-plate R and around axle V, which axle is screwed to base-plate Y. The horizontal cog-wheel G transmits its motion to a similar cog-wheel H, and this again to a similar cog-wheel I, of which the lower hub is provided with teeth J to serve as a feed-dog for turning the cloth around, and through a conical hole j in the center of the hub passes the needle up and down to make the stitches.
The lever B carries opposite the slot b aV pin K, which is inserted into a slot Z of another lever which carries on its opposite arm M a pin m, which passes into a slot 'n of the standard N to limit the movements of this lever. As often as the needle-arm of the sewing-machine raises, this lever L M turns the cam P for one curve and thereby moving through the stud Q the base-plates R and Y- in which the cog-wheel I with the conical needle-hole and the feed-teeth is held in position-to the side and at the same time making a partial turn.
The movement to the side of the feed cogwheel I produces the length of the stitch and the partial turn of same the distance between each stitch on the eyelet.
Having fully described my invention, what I claim, and desire to secure by Letters Patent, is
The combination in an eyelet-hole attachment for sewing-machines, of a base-plate, means whereby it is adapted to connect with the sewing-machine presser-bar, a frame pivoted to the base-plate, the connecting-pivot having a united cog-wheel. and bevel cog- Wheel F loosely fitted thereon, one end of the pivoted frame provided with a stud Q, and its opposite end with a feed-wheel I provided with a cog-wheel, and a cog-wheel II coperating with the cog-wheels on the feed-wheel and on the pivot, as described, a cam P, connected with the base-plate, so as to engage the stud Q, and the pivotally-connected levers, with means substanti all y as described, whereby motion is transmitted from the said levers to the cam P and the beveled cog-wheel F, and feed-wheel, as set forth.
