DARNING IMPLEMENT.

SPECIFICATION forming part of Letters Patent No. 501,817, dated July 18, 1893.

Application filed December 2,1892. Serial No. 453,838. (No model.)

To aZZ whom it may concern.-

Be it known that I, ADAM BocHER, a citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Darning Implements, of which the following is a specification.

This invention relates to a darning implement and the object of the'invention is to increase the reliability and ease of operation of the device and to thisend the invention consists in thenovel features of construction set forth in the following specification and claims and illustrated in the annexed drawings in which- Figure 1, shows a side elevation of the implement sectioned along 00 m Fig. 2. Fig. 2, is a section along y y Fig. 1. Fig. 3, is a plan View of Fig. 1. Fig. 4, isa section similar to Fig. 1 with parts in a different position. Fig. 5, is a front elevation of Fig. 4. Fig. 6, is a detail View of a hook set. Fig. 7, is a detail view of a modification.

The material D having the rent or hole to be darned is stretched over a frame or support 0 and is confined thereupon through the medium of a spring clamp composed of an elastic strip of metal or wire bent to form a pair of parallel arms E which grip opposite sides of the support 0. The arms E are bent to provide a pair of supporting arms E having their extremities formed into curved portions to provide lugs or projections E The action of the arm E in gripping the base or Support O is similar to that shown in United States Letters Patent No. 47 5,659, issued May 24., 1892, for an invention of mine in darning implements.

To the lugs or projections E is fulcrumed at E E an oscillatory lever frame composed of bell crank levers E E 7 The arms E E of the levers are joined by a rod or bar E carrying a handle or finger button E by which the lever frame can be swung to either of the positions shown in Figs. 1 and 4:. The arms F. E carry a head composed of two disks or plates A secured to a pivot or shaft X journaled in the arms E The hooks a a are extended from or formed on plates a a which are adapted to reciprocate in parallel planes and at their lower ends are bent about or jointed to the pivots Q Q on the disks or plates A. The pivots Q with the disks or plates A can be oscillated by handle R swinging on pivot X and engaging the pivots Q and as the disks or plates are oscillated the pivots Q likewise oscillate and each hook set a or a. alternately rises above and drops below the other hook set. This oscillation of the hook sets a a'produces a shedding motion in the thread I so that part of said thread first forms an upper shed and another part a lower shed and on shifting the hooks a a the part of thread I which before formed an upper shed now forms a lower shed and the thread parts which formed the lower shed now form an upper shed. The thread portions I are given this shedding motion toenable a needle and thread who run between the sheds as described in said PatentNo. t75,659. While theshedding motion and the consequent oper ation of darning or mending-is continued the disks or plates A and levers E? F. are held or fixed in the position shown in Fig. 1. The arm or bar E can be made to jam against the arm E with sufficient force to hold. the levers E E fixed in the position shown inFig. 1. The thread portions I are looped about the hook sets a a and also about the attaching devices or hooks 19. These hooks b are made swinging or movable on the pivots T connecting said hooks to the adjustable head B which is formed or otherwise provided with eyes B through which pass the arms E so that said arms sustain the head B and constitute a guide for the latter in its adjustment toward andfrom the head which comprises the disks or plates A. The hooks b canbe swung about pivot T by ahandle U and said handle U has a catch or catches V which in the position of parts shownin Fig. 1 engage a rack or shoulder W on the base Oso as to prevent the headB slipping toward head comprising the disks or plates A. The material .D may frequently cover the rack W but said material is pierced 'or pressed by the catch V sufficiently for the allow the threads I to be freed from the hooks b. At the same time the catch V is carried out of engagement with rack W so that the head B can be moved toward head A.

The hooks a a as seen in Fig. 2, are formed each with a hook side or dented side while the opposite side is straight or plain. The hooks a a face in opposite directions and when in theposition shown in Fig. 2 the hook parts are free to catch and hold the loops or thread I. When however the hooks a have been shifted laterally to the position shown in Fig. 5 the flat sides ofhooks a have pressed the loop I out of the hooks or dents of a and the fiat sides of hooks a have similarly forced the loops I out of the hook parts of hooks a.

The shifting of the hooks a is accomplished by pressing laterally on the handle R in one direction or another so as to shift said handle together with the plate a and hooks ct to one side or another. The plate a (Fig. 6) has a cut or slot Y large enough to allow lateral shifting of the handle R without moving the plate 0, or hook at. The plate a is provided with a spring tongue Z easily formed by cutting part of plate a and said tongue Z has dents or depressions b 5 flhe plate 0t has a projection or lip 19 In the position of parts shown in Fig. 1 the dent or catch b is in engagement with the lip or holder Z2 so as to prevent accidental shifting of the hooks a. When however the. handle R is forced to one side to the position shown in Fig. 5 the spring tongue Z is actuated so that the dent b is forced out of engagement with the lip b and the dent b snaps into engagement with said lip 12 The hooks 0t can not thus accidentally shift to one side or another. When the hooks to a are in their disengaging position as seen in Fig. 5 the loopsI of the thread are readily freed by dropping the hooks below the base 0 which can be done by pressing the button E with levers E E to the position shown in Fig. 4. The hooks Ct 01, will by this motion be dropped down or drawn out of the loops I. Of course this dropping motion of the hooks a a is not necessary since when the hooks are in the disengaging position the loops I might be stripped or pushed off by hand. In this case the levers E E would be dispensed with, the disks A having their pivot X then secured directly to the lugs E, as seen in Fig. 7.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination, in a darning implement, with a head provided with reciprocating hooks, of a head B provided with swinging attaching devices I), and a handle connected with said attaching devices for swingin g them to their releasing position, substantially as described.

2. The combination, in a darning implement, of a base 0 having a rack W, a head provided with reciprocating hooks a, a and a sliding head B having swinging attaching devices and a swinging handle U adapted to swing the attaching devices and provided with a catch V for engaging the rack, substantially as described.

3. The combination, in a darning implement, of a base having a rack WV, a head provided with reciprocatinghooks a, a, ahead provided with movable attaching devices I), and a movable handle adapted to move said attaching devices and having a catch for engaging the rack, said attaching devices and catch being made swinging so as to be capable of being moved to their releasing position, substantially as described.

4. The combination, in a darning implement, of a head provided with two sets of reciprocating hooks, one set beinglaterally movable and having a spring catch Z, and the other set provided with a projection b adapted to be engaged by the catch to hold the laterally movable set of hooks after it has been shifted, substantially as described.

5. The combination, in a darning implement, of a head 13 provided with attaching devices b, a head composed of two plates adapted to move in parallel planes and having hooks a, ct, a bell crank lever frame connected with the two plates, and devices carried by the bell crank lever frame for moving the two plates, substantially as described.

6. The combination, in a darning imple-'' ment, of a head B having attaching devices b, a head comprising two sets of hooks a, a which are adapted to alternately rise and fall in parallel planes, oscillating disks or plates A connected with said hooks, and a handle R for oscillating the disks or plates, substantially as described.

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

ADAM BUCHER.
