r General Description.

The sewing of the curved edges, :v,of an umbrella,

between the tips of the ribs, or the stitching together of the edges of the cover and lining of a parasohhas heretofore been performed entirely by hand. This is a slow and laborious operation, as the umbrella or parasol must be fully extended'when sewed, in order to prevent the edges from puckering, the usual method being tofrest the umbrella upon the lap, as shown in fig; 10, and then to bend over the same, and work upon the outer edge.

My invention, which has been designed to supermachine, which will enable the stitching to be brought close up to and over the ribs of the umbrella or parasol..

On reference to sheet 1 of the drawing- A represents any suitable frame for the support of a sewing-machine;

- B, the bed-plate of the machine; and

The other portions of the machine, with theexception of the presser-i'eet D D, which form' one of the features of my invention, may be similar to those in common use, and are not illustrated in the drawing.

' The holder for the'support of the umbrella or parasol to be operated upon by the machineis, in the present instance, connected directly to the machine, and consists of a longitudinally-slotted plate, F, secured to the arm 0; of a bolt, H, tendered adjustable in this slot-ted plate; of a disk, I, having a tubular projection, a, arranged to turn upon the said bolt; of a disk, I, attached to and arranged to-turu upon the disk I, and having curved slots, 7) b, for the passage of'setscrews, '0, by means of which the said disk I can be secured after adjustment; and of a long rod, J, rendered adjustable in a tubular projection, (l, of the disk I, and held thereinby a set-screw, e.

The holder proper consists of a segmental plate, L, hung to and arranged to turn upon the outer end of the .rod J, and having a curved slot, j, through which passes a'bplt, f, of the said rod, this bolt being provided with a thumb-nut, f, which can be tightened against the segmental holder,in order to secure the latter after adjustment. v The handle y'of the umbrella or parasol rests in jaws, h and h, of the segmental plate L, and ,is retained in a proper position therein (that is, in such a position that the edge of the extended umbrella shall be in contact with the bed-plate of the sewing-ma-- chine beneath the needle) by means of an adjustable block, M,-fnrnis'hed with a set-screw, which is fitted to-the handle of the umbrella orparasol, and arranged to rest upon the top of the upper jaw 71, and thus sustain the weight of. the umbrella. n

One or both of the jaws h and k may, if desired,

be provided with pins or catches, i, to prevent the ac cidental displacement of the handle.

The universally-jointed holder above described enables the umbrella or parasol to be adjusted to such a position that its edge may be brought directly beneath the sewing-machine needle, and also to such a posiing the edges'of umbrellas was in working close up to r and over the ribs, the ordinary pressenfeet being incfi'ectual, and permitting the work to slip, so that needies were frequently broken by being brought in contact with the ribs. This difficulty I have overcome by using two presser-feet, one on each side of the needle, and arranged to be raised and lowered independentlyot each other, so that one can be raised, and allowedto pass over the rib, while the other still holds and prevents the slipping of the work. The said presseofcet are also inclined on one'edge, so that they may adapt themselves to the inclined position of the rib, and thus permit the needle to work close up to and over the latter without risk of striking the same.

This is shown in figs. 4 and 5, where D and I) represent the presscr-feet arranged to slide in the fixed arm 0 of the machine, each foot being acted on by a spring,

j, which has a tendency to depress it, and by a le'ver,

It, by which it can be raised' from the work.

On reference to fig. 5, it will be seen that the curved edge as (which is in a position coinciding with a curve described from the center of the bolt H) has been sewed by the needle z, which occupies a positionmidway between the resser-feet D D. The sewing on this edge achas been brought close up to the rib w, the foot Dhariug been raised to permit the passage of the latter, and the inclined edge 1) of thefoot D, being in contact with the side of the rib, thus prevent- -ing any further feeding of the work in the'direction of the arrow, and consequent danger of striking the rib by the needle Z.

When the sewing has been thus far accomplished, and it becomes necessary to cross the rib, inorder to operate upon the 'edgex of the umbrella, the foot D is also raised, in order to permit the work to be turned upon the needle z as a center (the holder turning on the bolt H) from the position shown in full lines to that indicated by dotted lines in fig. 5, the inclined edge v of the foot I), which is depressed during the movement, determining the extent of the latter, as it scrvesas a guide for the edge of the rib.

The operation now goes on as before, and, when the rib has been passed, both of the presser-feet, or one only, can be held down, as desired.

by the handle only, as before described,

lar projection,

used in connection with a sewing 'machine, should be attached to the top of the latter, as above described,

as itmight be secured to the bottom of the frame, as shown in fig. 6, or to the ceiling, or to any other fixed object separate. from the machine, as illustrated in fig. 7. Nor is it necessary that the holder should be constructed precisely as above described, as it can be modified considerably without departing from my invention. In fig. 7 for instance, an adjustable hooked yoke, L, is substituted for the segmental plate, L, and the umbrella is held by the handle and tip, instead of and in fig. 9 the bolt H, disks I 1', 8m, are dispensed with, and a ball-audsocket joint, s, substituted for the same.

It should also be understood that I do not confine myself to the holder when combined with a sewing machine, as it will be found usefulJor holding uni brellas and parasols in a convenient position to be sewed by hand.

I therefore claim- 1. A holder for umbrellas and parasols, consisting of an adjustable and movable bar, or its equivalent,

constructed so that the handle of the umbrella or parasol may be secured to the same, substantially as described.

2. The combination, substantially as herein described, of the said holderwith a sewing-machine.

3. The combination and arrangement, substantially as herein described, or the bolt H, disk I, with its tubular projection, and slotted disk'l', with its tubufor the purpose set forth.

4. The adjustable segmental plate L, or its equivalent, attached to the bar J, and forming theholder proper, for the retention of the umbrella or parasol.

5. The combination of the said holder, the handle of an umbrella or 'parasol, and a detachable block, at,

adjustable on the handle, and bearing on the holder,

as specified.

6. The presser-feet D I), in connection with each other,

constructed and operating the needle, and the ribs ot' the umbrella or parasol, substantially as herein set forth.

v 7 The prcsser-feet, having edges 1: o, inclined as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
