Application August 2, 1954, Serial No. 447,061
2 Claims. (Cl. 112-2) This invention relates to an improved means for attaching an umbrella cover to the umbrella ribs and for sewing protective patches to the cover.
Heretofore, in the umbrella industry, covers and rib patches were sewed to the covers by hand. As is well known in the umbrella industry, the cover is sewed or attached to the ribs at an intermediate point, usually at about the place on the rib where the stretcher is jointed to the rib. This cover is frequently protected at this point by first sewing on a so-called protective patch. With the present invention, the tedious hand-sewing work is eliminated entirely.
This invention accomplishes the desired objects by providing in conjunction with a special chainstitch sewing machine, having a special support for the sewing machine head, a holder for the umbrella and a holder for the rib being worked on.
This invention also provides for the swift and simple machine operations of two heretofore difiicult hand operations, to wit, sewing tabs or patches on the umbrella ribs and attaching the cover to the ribs.
The machine herein referred to is of the type wherein the needle has an overcast or laterally reciprocal motion sometimes used in button-sewing. It is a sort of zig-zag eifect. In any event, the needle moves into and out of the fabric, first on one side of the rib and then on the other.
In the drawings:
Figure 1 is a perspective view, partly broken away and with certain parts omitted, of a sewing machine attachment constructed according to an embodiment of this invention whereby the cover of an umbrella may be attached to the ribs by a sewing machine which is shown diagrammatically.
Figure 2 is a fragmentary plan view of the device.
Figure 3 is a sectional view taken on the line 33 of Figure 2.
Figure 4 is a fragmentary sectional view taken on the line 44 of Figure 2.
Figure 5 is a sectional view taken on the line 5--5 of Figure 2.
Figure 6 is a sectional view taken on the line 6-6 of Figure 1.
Referring to the drawings, the numeral 10 designates the top of a table generally indicated at 11. A sewing machine 12 is mounted on the top 10 and, as shown in Figure 1, the sewing machine 12 is disposed at an angle to the vertical by means of a wedge-shaped member 14.
Wedge 14 is interposed between the machine 12 and the top 10 so as to tilt the machine or sewing head 12 rearwardly. The machine 12 is also disposed on an angle to the front edge 15 of the top 10, the purpose for which will be hereinafter described.
In order to provide a means whereby an umbrella frame with a cover partly attached may be supported in a position for securing the cover by tacking threads or stitching, I have provided a U-shaped cradle 16 which has the bight 17 disposed on the upper side of the table top 10.
The upright legs 18 of the U-shaped member 16 have secured thereto a pair of staff or umbrella staff holders 19. The staff holders 19 are of like construction and each is formed of a body 20 having an opening 21 through which the umbrella staff 22 is adapted to be loosely extended.
The body 20 is secured by fastening means 23 to a leg 18 and, as shown in Figure 1, the outer one of the staff holders 19 has a U-shaped saddle 24 thereof disposed uppermost. Each holder 19 has a body 20 with an opening 21 and a U-shaped saddle 24 oppositely from the opening 21.
The cradle 16 has secured thereto an elongated base bar 25 which is secured to the upper side of the bight 17 by fastening means 26. The bar 25 is formed with an elongated opening 27 through which a bolt 28 engages and the bolt 28 also engages through the table top 10.
The opening 27 is of suflicient length so that the cradle 16 may be moved toward or from the needle 29 of machine 12 to provide for tacking the cover at two spaced points to the ribs 30 of the umbrella frame. The ribs 30 are, as shown in Figure 2, disposed on an oblique angle with respect to the front edge 15 of the table and in alignment with the angled machine 12.
This angular relation of the machine 12 provides a means whereby one rib 30 at a time may be disposed on the table 31 of the machine 12. The rib 30 is yieldably and removably held in a position for stitching the cover C thereto by means of a pair of resilient presser members 32 which are secured by a headed bolt 33 to a support 34.
The support 34 is secured by fastening means 35 to a rearwardly projecting bracket 36 which is fixed relative to the forward end of the machine 12. The support 34 is formed of spaced lugs 37 and 38 between which the presser members 32 loosely engage.
The forward ends of the presser members 32, as shown in Figure 4, are formed of a curvature, as indicated at 39, so that the cover C and a rib 30 may be easily slipped beneath the two presser members 32 and the machine table 31.
In the use and operation of this attachment, the machine 12 is secured to the table top 10 on a tilted position by means of the wedge 14,
The machine 12 is also angled toward the left of the front edge of the top 10 so that the ribs 30 may be engaged one at a time with the machine 12 for stitching the cover C by tacking threads thereto, or for stitching tabs or patches to the umbrella ribs.
The staff 22 is mounted through the rear holder 19 and seated in the saddle 24 of the front holder. The cover is extended beneath the presser arms 39 of the presser members 32, as shown in Figure 4.
The cover is stitched by a series of stitches at circumferentially spaced apart spots to the ribs 30; and after one series of stitches are performed, the base bar 25 is shifted, preferably to the left, so that the endmost tacking threads may be applied to the cover and the ribs.
With an attachment of this kind, the cover can be quickly and firmly attached to the ribs, thereby eliminat ing the present operation of tacking the cover to the ribs; and patches or tabs may be likewise sewed or attached to the ribs.
What is claimed is:
l. A means for supporting an umbrella frame on a sewing table in a position to secure the cover to the frame, said means comprising a U-shaped cradle, a pair of rotatably adjustable stafi supporting members carried by the parallel arms of said cradle, a base bar releasably secured to the bight of said cradle, and means adjustably securing said base bar to said table.
2. A device as claimed in claim 1 in which said staff supporting members include a U-shaped stafi supporting jaw and an oppositely disposed opening for alternately supporting said staff.
