SEWING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 272,104, dated February 13, 1683.

Application Filed May 3, 1882.' (No model.)

.To all whom tt may concern:

Be it known that I, ORVILLE R. VAN VEGH- TEN, a citizen of the United States, residing in the city ot' Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in SewingMachines, fully described and represented in thefollowing specification and the accompanying drawings, torming a part of the same.

The present invention relates to a sewingmachine of the same general construction as Patents No.

The machine shown and described in lthose patents is designed and adapted for sewing together the mouths ol' bags, or for uniting the edges of short pieces of fabric, which can readily be held between the bars of a clamping frame, such as shown in said patents. The machine thus shown is, however, for various reasons, not fitted for use in uniting the edges of long pieces of fabric, and consequently the field of its usefulness is comparatively limited. lt is the object ot' the present invention to adapt this machine for use in sewing together long pieces of material, and particularly breadths of carpeting and like heavy fabrics, which cannot be operated upon by an ordinary sewing-machine.

To that endV the invention consists in various details of construction, both singly and in combination, as will hereinafter be fully explained and pointed out.

In said drawings, Figure l is a plan view of a mechanism such as shown in the patents rel'erred to, but modified so as to embody the present invention. Fig. 2 is a transverse vertical section of the same, taken upon the line m x of Fig. l. Fig. 3 is a vertical section taken upon the line a: w of Fig. 2. Fig. 4 is a horizontal section taken on the line t/yof Fig. 2. Fig. 5 is a transverse vertical section taken upon the line z e of Fig. 1. Figs. 6 and 7 are end and side views of a gage for properly ad' justing the edges of the material preparatory to sewing them together.

In using the machine, niodilied as herein shown, the edges of the fabric to be united, instead of being clamped between the bars ot a clamping-frame, as in the patents referred to, are impaled upon the pins l, which project from the edge ot' a table or counter, 2, which will be of sufficient length to receive the edges of the longest pieces of fabric which it is de sired to unite. The fabric is impaled upon the pins, so that its extreme edges, in which the seam is to be taken, will project above the edge ofthe table, the amount of such projection, and consequenly the width of the seam, being aecurately determined by means of a gage, 3, which is moved along from pin'to'pin, so that as the fabric is impaled its edges can be brought up snugly against thc ange 4 of the gage, and thus be made uniform throughout the whole length of the piece. The gage 3 is provided with a ring, 5, through which the operator can pass one of his lingers, so as .to conveniently slide the gage along from pin to pin, and also hold it in place while impaling the edges of' the fabric upon the pins.

The sewing mechanism proper of the ma.- chine herein shown is substantially the same as in the patents referred toand therefore reference is made to those patents for a specilic description of the same. The presser-foot is, however, in the present case modified in construction. It consists of a single curved plate, 6, pivoted or hinged upon the end of the bar 7, projecting from the needle-bar carrier, and is provided with a spring, n8, so arranged as to press the foot constantly inward and hold the fabric snugly against the cloth-plate 9, and yet yieldsufticiently to allow any inequalities in the fabric to pass and not impede the progress of the machine. The foot 6 is provided with a slot, 10, (see Fig. 3,] to permit the oscillation ofthe needle, which is a neces sary feature in a 'machine ot' this character.

The construction of the guiding frame or way upon which the machine travels has been changedin order to give the machine the necessary range of travel.

In the machine shown in the patentsreferred to the supports for the guide-bars and driv ing-rack are so arranged that the machine can only travel between two supports, which 'distance is sufficient for all the purposes for which IOO prevent the movement ot' the machine, the table oreounter 2 is provided at a suitable distance from irs edge with a series of brackets, 13, to the top of which is fixed the rack-bar 12. The front edge of this bar is provided with a series ot' teeth which engage with the driving-pinion14 of the sewing mechanism, (see Fig. 1,) said pinion and rack being kept in engagement b v the anti-friction Wheels 15, bearing against the opposite side ofthe rackbar, and carried by arms 16, extending from the frame ot the sewing mechanism above the rack-bar. The brackets 13 are also provided with short arms 17, the upper ends of which carry the prismatic guide-bar 11, which is nearly embraced by the long bearing 18 on the frame of the sewing mechanism. From this it will be seen that the supports for the guide and rack bars do notin theleast interfere with the travel ofthe machin-e. When the bearing 18 is made ot' considerable length, as shown in the present' case, it is evident that one arm and Wheel, as 15 16, will be sufcient to hold the mechanism in proper position and the wheel 14 in engagement with the rack 12. Gonsequently, although two arms and Wheels are shown, one may be omitted Without departingV vent case the same as in PatentNo. 256,518, re-

ferred to, except that in that patent the apparatus is stationary, since the end ot' the run of the machine is always at the same point, While in the present case the apparatus is made adjustable, so that the run can be terminated and the thread severed at any point desired. To accomplish this the severing-blades 19 20 are attached to a movable carrier, 21, provided with bearings which embrace the guide-bar 11 and the front edge of the rack-bar l2, as shown in Fig. 5. This permits the carrier to be moved to any desired point, it being-fastened in position, when adj usted, by means of the set-screw 22, which impinges against the bar 11, and the spring-catch23, which engages with the teeth upon the rack-bar.

rlhe severing apparatus having been placed at the point where it is desired to have the run of the machine terminate, the sewing mechanism will bearrested at the proper time and the needle held in its Withdrawn position, While the thread is severed by the action ot' the lever 24.- upon the projection 25 of blade 19, all as described in the patents referred to.

It will readily be seen that it is not essential that the needle should reciprocate in a horizontal plane. It may be arranged vertically equally well, in which case the material operated upon will lie upon the top ot the table, instead of hanging from its edge.

What I claim is-- 1. The combination, with the guide and rack bars, of 'the adjustable knife-carrier, substantially as described.

2. r1he combination, with the guide and rack bars, of' the adjustable knife-carrier provided with the set-screw and spring-catch for holding it in any adjusted position, substantiallbT as described.

' 3. In a sewing-machine which moves over the material operated upon, the combination, with the cloth-plate, as 9, ofthe hinged presser-foot, as 6, consisting of a single curved plate provided with the slot, as 10, substantially as described.

4. The conibinatiomwith the brackets, as 13, provided with the guide and rack bars, as 11 12, ot' the sewing-machine frame, provided with the partially-open bearing 18, and arms, as 16, carrying anti-friction Wheels, as 15, substantially as described.

5. The combination, with the table provided with the impaling-pins, as 1, of the movable gage 3, provided with the flange 4, substantiallyas described.

In testimony whereof' I have hereunto set my hand in the presence pf two subscribing Witnesses.
