GUIDE FOR SEWING HARNESS.
SPECIFICATION forming part of Letters Patent No. 256,988, dated April 25, 1882.
(ModeL) To all whom ti may concern: Be it known that I, WILLIAM C. DUFFEY, of Calhoun, in the countyof Gordon and State of Georgia-,haveinvented certain new and useful Improvements in Sewing-Guides for Harness- Work, ofwhich the following isa specification. The invent-ion consists in asewing-machine attachmentformed ofa spring-plate attachable to the bed of a machine so as to hold the guides and channeling-knives above said bed and allow of their adjustment by slots and screws,as hereinafter described.
Reference is to be had to the accompanying drawings, forming part of this S1)6Clfi0&lil0ll,lll which similar letters of reference indicate corresponding parts in all the figures.
In the drawings,Figure 1 is a side elevation of the guide at the feeding side. Fig. 2 is a plan view of the same. .Fig. 3 is a sectional side view in reverse of Fig. 1; and Fig. 4. is a detailview, showing the relative position of the guide-rollers and the cutters. Y
The guide is to be used with any manufacturing sewing-machine.
A represents the bed-plate of such a machine.
B is the body of the attachment, consisting of a metal plate bent at the end, by which it is attached to the bed, the attachment being by screws a.
b b are slides carrying guide-rollers c c, and held in slots d of plate 13 by clamping-screws 6, so that the rollers can be set at the proper distance apart. Between the slots 61 the plate B is arched, and a screw,f, in the arched portion carries at its lower end a pressure-roller, g. By this construction the plate B serves as a spring-arm that presses rollerg upon the material with more orless force, according to ad- 0 justment of screwf.
The channeling or grooving knives h h are attached to plate B by a screw, i, tapped through the knife-plates, so that the knives extend behind the guide-rollers, one above and the other below the plate. The upper knife is provided with an adj ustin g-screw, 7:,bearing on plate B, so that the cutting-edge is retained at the proper elevation. The upper knife, h, also carries a screw, 1, that extends through a slot in plate B and bears on the lower knife for use in pressing the knife ends apart.
The attachment is to be adjusted on the machine-bed to bring the cutting-edges of the knives in line with the needle. The material passes beneath roller 9 and between rollers c c, and the knives, acting upon the upper and under side, out a groove or channel for the stitching. By adjusting the slides b carrying rollers c, the groove is formed at the desired distance from the edge.
Either knife can be used without the other, and the cutting-edges be shaped to form a groove of suitable size, according to the character of work.
The guide can be used for making round reins and stitching traces and straps. It is also adapted for use for raised stitching, which can be done without the pressure-rol!er hearing on'the raised portions.
I am aware that it is not broadly new to combine two horizontal guide-rolls with an upper and lower channeling-knife; but
What I claim as new is- A slotted and apertured plate-spring, B, arched to carry the top guide, twice bent at one end where it is to be attached to the bed A, carrying the channeling-knives 011 opposite sides, the pressure-roll suspended from the arch, and the side rolls arranged on each side of the arch, said knives and the holders of the rolls being adjustable by screws, whereby there is formed an attachment which may be used in connection with a sewing-machine, as and for the purpose specified.
VILLIAM G. DUFFEY.
