DEVICE FOR DARNING PURPOSES Filed Dec. 22, 1947 A T TOP/M55 Patented F eb. 19, 1952 DEVICEFORDARNING PURPOSES Dusinusv Peder Christensen, Aalborg,v Denmark Application December 22,-1947', Serial N02 793,172 lnxD'enmark'December- 23, 1946' 6. Claims.
A. device for the darning of holes of cloth is own. device has a series of revolving needles, round which thethread; which is drawn in one direction of the hole, is placed in such a manner that eachneedle has twothreadsparallel to-eachother which b the-turning of the. needle alternately are brought tone in. the top position, so that the cross. threads can. easily be carried in between the above mentioned longitudinalthreads. This device involves the iiiconveniencethat: one end of the' darning formed is not connected with thematerial bein darned, sorthat this end must be fastened by-sewing afterwards. Furthermore, it involves the: inconvenience that the placing of the devicetakes arather long time,- as part of it is to beplaced in the subject which is to be darned, after which another part is to be placed on the outside and connected with the first part by means of an elastic band.
, These inconveniences have been avoided with thepresent'invention, which relates to a device for darning purposes, thereby that the longitudinal threads are not bent round theneedles, but drawn beside these, so that they come in under-ahoole of the needles, by means of which every second thread can be lowered. and raised alternately, so that the cross threadsz canbecarried in between the longitudinal threads.
Further; adevice is known,in which two combs are movably arranged beside each other in a slit in ahead for the" supporting" of the-longitudinal threads for darning. This device can, however, only be used for darning coarser" ma-' terials, not for such things as silkstockings, as the teeth of the movable combs which are not in operation during the Work -Which: the'case when smaller holes are darnedat theupwards and downwards movement damage" the stocking by their pressureoutsidethe hole.
This inconvenience has been avoided with the present invention, as the upward and downward movableneedles are'only pulled downwards during thework.
Furthermore, the darning cannot-be finished with the known device; asathe combs" are beside each other and thus prevent the carrying through of the last cross threads;
This disadvantage has also been avoided with the device according the invention by. one row of needles.
The characteristic feature of the invention is that a row of needles is fixed in the slit of the head, every second of which is fixed to one plate, and every second to another plate, which plates are situated one above the other in a -space of the head; and are individually movable downwards and upwards. To either of thepl'ates is fixed a band ofelastic material, which is fixed to arail of the handle-ofthe device, against which .band a push buttompr-esses; .which is movhavingonly 2 ably arranged in the handle, while in the top of the. handle pins or rolls are arranged, which support the bands. As an alternative embodiment the plates in which the needles are fixed are arranged adjacent. each other in the head, each fixed toa movable rod, which is guided in the handle-andhas on its side apin whereby a sloping'f-a'ceof apush button can influence the rod to a downward motion.
Inthedrawing shown I v Fig. 1 a-verticallongitudinal section of a device according to the invention,
Fig. 2 is a section taken on the line 22 in Fig; 1,
Fig. 3 is a; section taken on the line 3-3 in Fig; 1,.
Fig. 4 is a section taken on the line 4-4 in Fig. 1,
Fig; 5 is a. detail,
Fig. 6 is a vertical longitudinal section of another form of construction of the invention,
Fig: 7 is a section taken on the line 1'|' in Fig; G'and Fig. 8 is a detail.
The device consists of a dish-shaped head I with a handle 2; The head has a channe1'3, into'whichlthree plates; 4, 5 and 6, are inserted; o'ne'above-the other. The plate 5 is stationary in the channel 3, whereas the plates or supporting'bars l'and 6 are movable upwards and downwards in the channel. To the plate 4 are fixed a" number of needles 1; and to the plate 6 are fixed a'further number of needles 8. The needles 8- pass loosely upwards through some holes in the plates 5 and 4-; To the underside of'the plate 4 there is fixed a'band 9of elastic material and this band 9 is further fixed to a rail III at the bottom end of the handle 2. Theba'nd passes loosely through holes in the plates 5 and 6 and is'supported by a pin or'roll I'l fixed at the top end of the handle: 2. To the underside of the plate 6' is fixed another band I2, whichat its foot is also fixed to the rail H]. The band [2 is supported by a pin or roll I3 arranged at' the to'p' e'nd ofthe handle. In handle 2 push buttons I4: and" I5 'aremovably arranged to press against the band 9 and the band l2 respectively. Between the plates 4' and 5 a spring I6 is arranged at each end of the plates; under the influence of which the plate 4 is" kept raised. Between the plate 6 and: the bottom of the'channel 3 a spring I! isarranged at each end, which keeps the plate 6 raised. Thus the supporting bars 4 and 6 are: biased to urge them in positions to normally expose and extend the needles land. 8
from the hollow head I. At the top the. channel 3- iscovered-with a 'plate l8 having a narrow slit l9, intowhich the needles can be drawn. down.
In use the material which is tobe darned is placed; on the-"top of the head I- and fixed to the device by means ofan elastic band in a groove 20 of the head I. By means of a darning needle longitudinal threads are placed over the hole of the material in such a manner that the longitudinal threads are stitched into thematerial at either end of the hole. During the drawing of the longitudinal threads these are carried in under a hook of the needles 1' and B. When the longitudinal threads have been drawn, the push button 14 is pressed, whereby the band 9 will be curved, and the latter will pull the plate 4 with the needles I downwards, so that every second longitudinal thread is pulled downwards, by which an opening is formed between the longitudinal threads. By means of the darning needle a cross thread is carried through the opening, after which the push button i4 is released, and the push button I5 is pressed, whereby the plate 6 with the needles 8 is pulled downwards, so that an opening between every second thread is again formed. When all the'cross threads have been drawn, the hooks of the needles are drawn out by pulling the material a little sidewards.
In the form of construction of the invention shown in Figs. 68 the plates, in which the needles are fixed, are, arranged adjacent each other instead of one above the other. These plates or rods are 2! and 22 respectively, either of which is fixed to a rod 23, which is movably arranged in the cross piece 24 of the handle 2, Each of the rods 23 has at its side a pin 25, against which a sloping face 26 of a push button 21, movably arranged in the side of the handle 2, presses.
Off each of the needles The rods 23 together with the needle plates 2| and 22 are kept raised under the infiuporting bars being movably mounted in the hollow portion in the head member and being biased to urge them in positions to normally expose and extend the needles from the hollow portion in the head, and means in the handle member to actuate the supporting bars to draw the needles into the hollow portion in the head against the biasing action. a
2. A device for darning and repairing woven fabrics comprising a head member provided with a handle member, said head member having a hollow portion therein, a pair of supporting bars each provided with a row of needles, said supporting bars being movably mounted in the hollow portion in the head member and being biased to urge them in positions to normally expose and extend the needles from the hollow portion in the head, a rod fixed to each supporting bar, and means in the handle to actuate the rod to draw the needles into the hollow portion in the head against the biasing action.
3. A device for darning and repairing woven fabrics comprising a head member provided with a handle member, said head member having a hollow portion therein, a pair of supporting bars each provided with a row of needles, said supporting bars being movably mounted in the hollow portion in the head member and being biased to urge them in positions to normally expose and extend the needles from the hollow portion in the head, a rod fixed to each supporting bar and a push button in the handle for each supporting bar to bend the rod and thereby draw the needles into the hollow portion in the head against the biasing action.
4. A device for darning and repairing woven fabrics comprising a head member provided with a handle member, said head member having a hollow portion therein, a pair of supporting bars each provided with a row of needles, said supporting bars being movably mounted in the hollow portion in the head member and being biased to urge them in positions to normally expose and extend the needles from the hollow portion in the the needles 3!! and 3|, which are not pulled down,
and one of the rails 32. The alternate pulling down of the needles is effected by pressing one or the other of the push buttons 21.
The grooves 33 serve to take up the thread drawn down by the needle, in order to render a larger interspace between the raised and the lowered threads, which will facilitate the carrying of the cross threads through the interspace.
When a device according to this form of construction is to be used it is applied to the fabric to be darned, after which the longitudinal threads are drawn as described above. Then one of the push buttons 21 is pressed by which all the needles 30 are pulled downwards, thereby pulling every second of the longitudinal threads downwards, so that the needle with the cross thread can be carried in between these and the threads of the needles 3!, which are in their top position. When the cross thread is carried through, the push button 21 is released, and the other push button 21 is pressed, by which the needles 3! with their threads are pulled downwards.
I claim:
