IMPRovEMENT 1N LACE-MAKING MACHINE..

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, GEORGE OsBoENE, of Brooklyn, Kings county, New York, have invented a new and useful Improvement in Lace-Machines; and I do hereby declare that thefollosving is a full, clear, and exact description thereof', which will enable others skilled'in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which v Figures 1 and 2 are vertical transverse sections of a lace-machine, provided with my improvements.

Figure 3 isa front elevation of the same.

Similar letters of reference indicate corresponding parts.

The object of this invention is to so construct lacemachines, used for making fme silk, or other net-work of the kind used for invisible coverings of ladies chignons, and for other purposes, that the operation can,` witlh very tine material, be successfullycairied on; an

The invention consists in an attachment to the ordinary lace-machines now in use, wherehy the work can be readily moved back on the needles, as the sinker-Web for that purpose is not strictly reliable, on ne work. This attachment is a bar orstrap, Working back of the sinker-wcb, or rather in the same, and under the needles. s

It is, during the backward motion ofthe. sinker-web, carried back under the needles, and serves to carry the Work back over the barbs ofthe same.

By means of this attachment slack-work can be produced, as the fine threads are vnot so severely strained as they are by the sinkers, and the operation is entirely reliable and successful.

A, in the drawing, represents the frame of a lacef machine of-ordinary or suitable construction.

B B are the barbed needles,'armn ged in a horizontal row on the frame A, as usual.

In front of these'necdles is the Well-known or suitable mechanism for placing the loops upon Vthepneedles in the requisite succession.

0 O is the sinker-web, attached to an oscillating, that is .to say, up-and-down. as well as backward-andforward moving frame D, whichis operated by'suitable mechanism, in the ordinary or suitable manner.

.Without straining the thread, so that when the barbs' are held down by the presser, the said fabric may be thrown off the needles by the forward motion of the sinkers.

The sinkers are indented or hook-shaped, and will,

when let down, as in iig. 2, iit over the bar or strap E, and carry it back with them.

They are then elevated, as in fig. 1, and moved forward, to throw the fabric off the needles.

In the ordinary machines the sinkers alone had to carry the fabric-back, and did it successfully where the threads were suiciently tense and strong. But in light slack fabrics the threads are apt to be merely stretched and strained by the sinkers, Awithout being moved back on the needle.

By the use of the bar or strap E, this inconvenience is entirely overcome, as it will move all the threads back, without any strain or other difficulty whatever.

I do not confluemyself to nor claim any peculiar kind of lace-machine to which my improvement is attached, nor any particular mechanism for operating, nor means of supporting the same; but

I do claim as new, and desire tosecure -by Letters Patent- In combination with the needles B, the sinkers'C and the slotted frame D, the baror strap E, arranged to slide upon the pins a, substantially-as described, for

the purpose specified..

The above specification of my invention signed by me, this 27th day of March, 1869.

GEORGE OSBORNE. v
