UNITED STATES PATENT OFFICE.
ENOGH JAOKMAN, OF coNooEn, AND FREDERICK FLANDERS, OF FRANKLIN, NEW HAMPSHIRE.
, MANUFACTUREIOF LATCHES FOR KNITTING-MACHINE NEElDLES.
SPECIFICATION forming part of Letters Patent No. 224,541, dated February 17, 1880.
Application filed June 21, 1879.
To all whom it may concern:
Be it known that we. ENOOH JAGKMAN, of
Concord, in thecounty of Merrimack and State of New Hampshire, and FREDERICK FLAN- DERS, of Franklin, in said county and State, have invented a new and useful Improvement in; the Manufacture of Latches for Knittinglatch or tongue is provided with a coating, or
constructed from coated \vire, so that when 1 I attached to the needle, and after having been 15 secured in the slit thereof, the coating may be. removed by the application of heat, thus preventing the needle from binding the latch, and allowing it to turn easily and freely upon its pivot as it opens and closes in the operation otknitting. I
In the accompanying drawings, Figure 1 is a view of the needle constructed in the ordinary manner, with the latch in position.
2 is a View of the latch- Fig. 3 is an enlarged I needle, and the rivet.
tion with the coating removed. I Fig. 5 is a section, showing the latch and its coating, the
Fig. 4 is a similar secsection upon line 00 i, Fig. 4..
, The latch a is coated or made from wire w such as zinc, antimony,lead, copper, or other coated with a suitable metallic substance,
' substance, alloy, or composition hard enough toresist the pressure of the rivet and sides of theneedle while the latch is being secured in the slit, soft enough to be capable of removal by heat, and of proper thickness.
The latch, provided with the coating a, has its rivet-hole a made slightly larger than the rivetholes in the needle, and is placed within the slit and the rivet driven in thoroughly, so asjto upset in the latch-hole a and form a shoulderjust within the slit, so as to prevent the rivet from working out. Heat is then applied to the latch, and the coating melts oft" from the latch, thus leaving a space, on both sides thereof, and also around the rivet. By means of these spaces (seen in Figs. 4 and 5) the latch .isallowed to freely inove. Of course,
were the coating not melted oil the latch would bind, and the more thoroughly the rivet was upset the more inoperative the latch would become.
By means of our device the rivet may be thoroughly hammered down, and by varying the thickness of the coating the width of the spaces between the latch and the sides of the slit regulated.
Our improvement is a great advantage over the method of placing paper or other foreign, separate, unattached substance between the latch and needle, as our coatingis integral with the latch, and hence the difficulty and expense of inserting a foreign substanceis entirely obviated.
Another advantage possessed by our improvement over the old method of applying a shim of paper or similar substance to the latch after the paper is removed by heat is avoided.
Again, the coating is hard enough to be reliable, and yet easily penetrated by the rivet.
Other advantages of this method of manu facture might be named.
Having thus fully described our invention, what we claim, and desire to secure by Letters Patent, is V In the manufacture of latches or tongues for knitting-machine needles, the application to and employment upon such latch or tongue of a suitable metallic or other coating, such coat ing being applied to the latch, or to the material of which the latch is made, before the insertion of the latch in the slit of the needle, and said coating being designed to be removed by the application of heat after the latch has been permanently placed in the needle, substantially as and for the purpose hereinbefore set forth.
