Letters PatentNo. 88,808+, dated April 13,1869.
IMPROVEMENT IN snwmemmc'nmn.
The Schedule referred to in these Letters Patent and maldng part of the same.
To all whom it may concerni Be it known that we, HEINRICH POLLACK and En- Wm SCHMIDT, of Hamburg, Germany, have invented a new and useful Hand-Sewing Machine, with a Right- Working Hook; and we do hereby declare that the following is a full, clear, and exact description of the con- 3 stru'ctiouand operation of the same, reference being had to the annexed drawings, making a part of this specification, in which Figure 1 is a front view;
Figure 2 a side view; and
Figures 3,4, 5, 6, and 7, separate views of the parts.
The same letters indicate the same parts in each of the figures. 1
The form adopted for this machine has the advantage, that-all parts of it are covered by a rim, T, forming partof the stationary frame, and by a flange, b, onthe driving-wheel B, and are thus protected, as far as possible, from injury and derangement.
The small cut-out S, fig. 2, in the foot of the ma chine, serves to give a firmer position and hold to the clamp that fastens it to the table.-
- When the machine is to be arranged to be worked by the foot, the fly-wheel B, fig. 2, receives a groove for the bands.
The upper arm, having-a plain, round shape, without projections, the machine can be the more easily I held and moved from place to place.
The machine is set in motion by the cog-wheel A,
attached to the fly-wheel B, and which moves the shafts O and D by means of the smaller cog-wheels E and F- The shaft 0 moves the needle-bar G by means of the crank-pin I, fig. 2, attached to the disk H, fig. 1, and which moves in the groove of the cross-head K, fixed on the needle-bar G.
The friction of the crank-pin against the cross-head is lessened by means of a steel roller turning on the crank-pin.
Shaft D; fig. 2, has on its front'end the hook L, fig. 1, which turns to the right, as indicated by the arrow 1.
Behind the .hook L, fig. 2, is the doubleeccentric M, on the shaft D. This lifts and pushes the feedbar N, figs. 5 and 6, in such a manner that the fabric moves in a direction contrary to that of the hook,
whereby a much firmer and more: regular stitch is ob-- 'tained, with a much less tension than is possible with a machine having ahook working to the left.
The tension appai-atus is so arranged that a new reel can be put ou'the pin 0, figsel and 2, by unscrewing it from the body of the machine.
f The reel P falls ofi", while the upper part remains resting on a set-ofi' on-the pin 0;
The stitch-regulator on the cloth-plate, already patented by us, in the United States, has been adopted by us in the present machine.
In addition to the great advantage of using a straight needle in the hook-machine, we have so constructed spring U as the pin is pulled out or shoved in, forthe purposes of throwing the bobbin-winding apparatus in or out of motion, as the case may be.
The revolution of the pin Q is produced by the friction of an India-rubber roller, R, against the inner surface of the fly-wheel B.
The winding-spindle is put out of motion by bring- I 'ing the pin Q into the position represented bythe dotted lines in fig. 7 This is accomplished by drawing out the pin as far' as the spring allows, whereby the roller is removed from contact with the fly-wheel.
\Vhat we claim as our invention, and desire to secure by Letters Patent, is-
1. The bobbin-filling apparatus Q R, constructed as described, and arranged within and in combination with the flanged driving-wheel B b.
2. Further, the arrangement of the driving-wheel B, flange b, and rim T, to enclose and protect thegearing A E F,as herein represented and described.
