IMPROVEMENT IN REGISTERS FOR TUBULAR-KNITTING MACHINES.

Specification forming part of Letters Patent No. 145,509, dated December 16,1873; application filed July 14, 1873.

To all whom it may concern:

Be it known that I, DANIEL A. LEIIMAN, of WVakarusa, in the county of Elkhart and State of Indiana, have invented certain Improvements in a Measuring Device for Tubular-Knitting Machines, of which the following is a specification:

This invention has for its object to provide knitting-machines of that class which knit a circular web or tube with an automatic measurin g device which will indicate, in inches and fractions thereof, the length of the tube or cylinder as fast as the same is knitted; and it consists in a rule sliding through aslot in a standtop, to the front edge of which the machine is secured. The foot of the rule or measure is attached to a horizontal bar which moves between vertic. 1 guides at the front of table,.being drawn up by a cord and weight, with a pedestal at the front end, upon which rests the tension-weight of the machine, which carries it and the measure down as the knitting progrosses.

Figure l is a perspective view of a knittingmachine and stand with my improvement applied thereto. Fig. 2 is a cross-section of the same on the line a 01;, Fig. 1.

In the drawing, A represents a stand or small. knitting-table, to the front edge of which is secured any knittingmachine, B, which knits a cylinder or tubular web. In the front of the table-frame is a pair of vertical guides, O, in which slides a guide-block, D, through which is mortised a horizontal arm, E, at the front end of which is a pedestal, F, on which rests the tension-weight used in such machines to give the required tension to the fabric. At the inner end of the arm E is secured the foot of a vertical measuringrod, Gr, whose face is divided off into inches and fractions, sliding through a slot in the table-top. His a cord secured to the top of the block D, led over the rollers I I, and has a weight, 11, secured to its free end, which draws up the sliding rule and its attachments whenever the tension.- weight is taken off the pedestal F. As the knitting of the tubular web proceeds, the tension-weight, bearing upon the pedestal, draws or forces down the scale indicating thereon, at the plane of the table, the length of web knit.

The stand, with the measuring device, may be sold to owners of knitting-machines, who can apply the latter thereto; or, where the machine is already mounted, (which is not usu ally the case,) the measuring devices may be applied thereto.

The improvement is applicable to all machines of this class, and requires no alteration in or addition to the running-gear of the same, and, once applied, requires no further adjustment. As it measures by the inch and fractions thereof, the measurement will always be accurate, whether the material be coarse or fine, or' the knitting tight or loose, being superior in this respect to those devices which simply register the number of rows knitted.

IVhat I claim as my invention, and desire to secure by Letters Patent, is

The guides (J, block 1), arm E, pedestal F, scale-rod G, cord H, weight H, and guidepulleys I I, in connection with any suitable stand and a circular-knitting machine, substantially as and for the purpose set forth.

DANIEL A. LEHMAN.
