DARNlNG-LASTA SPECIFICATION forming part of Letters Patent No. 441,709, datedDecember 2, 1890.

Application filed November 9, 1 889.

To all whom it may concern.-

Be it known that 1, CHARLES H. SHAW, of Brooklyn, Kings county, and State of New York, have invented a certain new and useful Improvement in Darning-Blocks, of which the following is a specification.

This improvement relates to blocks employed for darning stockings and other arti- I will describe a darning-block embodying my improvement, and then point out the novel features in claims.

In the accompanying drawings, Figure l is a front view of a darning-block embodying my improvement. Fig. 2 is a back View. Fig. 3 is an end view. Fig. 4 is a side view. Fig. 5 is a front view of the block covered with a fabric to be darned, and showing a number of hooks, which are used in connection with the block as adjusted into one position, and a needle traversing a number of loops of thread extending from the hooks. Fig. (5v is a similar view showing the hooks adjusted into the reverse position and a needle traversing a number of loops of thread extending from a series of movable hooks and the appurtesite end of theseparts. Fig. 9 is a front view of the hooks and a box in which they are journaled, with the front of the box and certain other parts removed.

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

A designates a block, which willpreferably be made of wood. At the front portion of its two sides it is provided with shoulders or rabbets a M, at one end with a groove a and at the other end with a spring A.

B designates a frame, which may most advantageously be made of metal. As here shown, it is of rectangular form to conform to the shape of the block, which in the present instance is made of rectangular form. The

other fabric to the block while extended over the front of the block.

The spring A is shown as consisting of a strip of metal fastened to the back of the block and extending across one end of the block, it being bent away from the end of the block, so that its extremity will be free to move toward and away from the end of the block. The resilience of the spring tends to move its free extremity away from the end of the block. At the free end of the spring is a catch or projection a, which is forward of the-frame B when the frame is in place, and therefore, in combination with the groove 60 at the opposite end of the block, will prevent the frame from being moved off the block accidentally.

To secure a fabric, the frame B is first re moved from the block by bending the free extremity of the spring A inward to allow the adjacent portion of the frame 13 to pass the projection a of the spring, or the whole frame is moved in such a direction as to force the free extremity of the spring toward the opposite end of the block and is moved sufficiently far to disengage the opposite portion of the frame from the groove a of the block. After the frame shall have. been moved in either of the ways just indicated it may be moved forwardly off the block. Having re- So moved the frame, the fabric is spread over the face of the block with the portion requiring darning across the front of the block. Then the frame is reapplied to theblock and serves to fasten the fabric to the block. The frame may be reapplied by inserting one of its end portions into the groove at, with the fabric between it and the groove, and then slipping the opposite end portion past the projection a of the spring A, or the frame may be reapplied, if preferred, by placing one of its end portions behind the projection a of the spring and then moving it in such direction as to force the free extremity of the frame toward the opposite end of the block sufficiently far to enable the other end portion of the frame to pass beyond the face of the block to a plane opposite the groove 0 whereupon the pressure againstthe spring will be relaxed and thelatter allowed to move roo the frame in such direction that the frame will enter the said groove a The front of the block is shown as provided with grooves a a, in which are fitted strips of soft materialsueh, for instance, as felt. The object of inserting soft material is to afford facility for the insertion of pins employed to secure to the block the devices which are employed in connection with the block in the operation of darning.

G O designate two series of hooks which are used upon the face of the block after the fabric is secured thereto. The hooks C are movable. The hooks 0' need not be movable. The hooks C are shown as formed upon a plate 0', having pivotally secured to it pins 0, which are inserted through the fabric into the strips which fill the grooves a a of the block. The hooks C are pivotally connected to a support, here shown as consisting of a box 0 having its longitudinal edges 1 2 turned upward, or,in other words, forward,and provided with holes or notches in which the shanks of the hooks G are supported, so as to be free to oscillate. Across thefront of thisbox a plate 3 extends, and, as here shown, this plate has its ends bent backward to close the ends of the box 0 The plate may be secured to the box by having its ends united therewith in any suitable manneras, for instance, by soldering. hen the bearings for the shanks of the hooks C are made in the form of notches, the plate 3 will serve to retain the hooks in place. Those extremities of the shanks of the hooks which are opposite the hooks themselves are turned forward, so as to form arms 0, and these arms in the present instance enter openings in a plate D, which is free to slide lengthwise of the box a and its plate 3. The openings of the plate D,

which receive the arms a, are here shown as made in the form of notches in the edge of said plate. The plate D is guided in its movements and fastened to the box a in the present instance by being provided with longitudinal slots (Z, through which pass pins (1' (Z which have on the outer ends heads extending over the edges of the slots, and at the inner ends are secured to the plate 3 of the box 0 By sliding the plate D lengthwise it will oscillate the hooks 0 simultaneously. Preferably the plate D will be provided with a hand-piece D by which it may be manipulated. The box c has pivotally connected to it pins 0, which may be inserted through the fabric to be darned and into the material filling the grooves a a. The pins 0 of the plate 0 and of the box 0 when inserted, are turned toward one another, so as to be able to resist a pulling-strain exerted between the opposite hooks C (1 The hooks and their appurtenances will preferably be made of metal.

Assuming that the fabric has been secured and the hooks C 0 applied to the block, I will now explain how the darning is to be performed. First, the needle containing the darning-tln-ead is passed through the material to be darned close to the first of the series of hooks 0. around said hook to a hook C opposite the first hook C, then around the opposite hook G afterward around the second hook C, and subsequently forward and backward around the hooks C C, until there shall be formed in the thread loops extending across that portion of the fabric which is to be darned. During the looping of the thread it will be found convenient to adjust the hooks G into their central position, or, in other words, so that they and their arms a extend directly for ward. The needle will nowbe passed through the fabric close to the hooks C, as in the ordinarv method of darning. It will preferably be passed several times across the loops and fabric close to the hooks G in this way. The looping of the threads and the securing of the loops to the fabric adjacent to the hooks 0 having been completed, the hooks C are to be oscillated over into one of their extreme positions. As a result of this, alternate threads in the loops of the hooks will be elevated from the face of the block and fabric and the intermediate threads depressed or moved nearer to the fabric. After this the needle is passed, preferably eye first, behind the elevated threads of the loops, but above or in front of the depressed threads of the loops throughout the series, and after the needle has been drawn through, so as to lay a portion of thread between the raised and depressed threads of the loops, the portion of thread so laid through the loops will be worked down toward the hooks C by the needle or otherwise. The thread having been laid through the loops, the needle will be passed through the fabric adjacent to the loops and the thread drawn through. Now the hooks C will be oscillated into their other extreme position, so as to elevate those threads of the loops which by the first oscillation of the hooks were depressed, and so as to depress those threads of the loops which at the first oscillation of the hooks were elevated. This having been done, the needle is again passed through the loops and a new portion of thread laid within the loops and worked down toward the hooks O. The needle is then" passed through the fabric again adjacent to the loops and the thread drawn through. The operations already described are repeated asuflicient number of times to weave or darn a fabric across the hole in the fabric to be mended and unite the newly-made fabric to the old. Then the weaving shallhave been completed close up to the hooks C the needle will be passed one or more times across the loops and into the old fabric close to the hooks (3 The frame maybe disengaged from the block and the hooks C C are now to be disengaged from the fabric. This may be done by taking hold of the outer edge of the plate 0 and the outer edge of the plate D or of the box 0 and rocking the same upward upon the hooks as a center of motion to disengage the hooks The thread is then passed from the loops. If then the fabric be pulled or stretched out around the darning or weaving, the extremities of the loops will be drawn into the meshes of the old fabric and Will be scarcely discernible.

The hooks C may be dispensed with if during the operation of looping the needle is caused to engage the loop-thread with the fabric at points corresponding to the hooks C. lVhat I claim as my invention, and desire to secure by Letters Patent, is
