WORK-RECEIVING ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent N0. 773,7 58, dated November 1, 1904.

Application filed March 12, 1904.

To all whom it may concern:

Be it known that I, CARRIE I. LATSHAW, a citizen of the United States, and a resident of Bradford, in the county of McKean and State of Pennsylvania, have invented certain new and useful Improvements in Work-Receiving Attachments for Sewing-Machines, of which the following is a specification.

This invention relates to work -receiving attachments for sewing-machine tables, and has for its more prominent objects simplicity of construction, convenience of application and adjustment, as well as facility for being arranged in a highly-compact manner when not in use.

WVith the above and other purposes in view the novel work-receiving attachment comprises two appropriately-constructed sections hinged together at their lower edges and having flexible connections preferably in the form of straps at their tops near their ends, so that when one section is maintained in a vertical position the other will be supported at such angle thereto as to provide a receptacle suitable for the purpose desired, the vertical section being equipped at its top with short horizontal arms designed to be adjustably and detachably clamped at the under side of the table of a sewing-machine at the longitudinal edge farthest from the operators position through the medium of appropriately-shaped keepers adapted to be secured in position and provided with clamping-screws. In addition to the foregoing that section adapted to occupy a position at an angle with respect to its companion is externally provided with hinged legs or supports adapted when the attachment is in use to be lowered to aid in sustaining the weight of the work. These legs or supports are capable of so coacting with turn-buttons that when it is desired to compactly arrange the attachment whether still connected with the table or for the purposes of stow-age or transportation said legs or supports can be folded and secured parallel with the section to which they are attached. Further, said latter section can be folded and secured against its companion.

There are other important features connected with the invention, which besides those Serial No. 197,762. (No model.)

alluded to are clearly set forth in the subsequent detailed description.

In the accompanying drawings, forming part of this specification, Figure l is a fragmental end view of a portion of a sewing-machine table with my attachment applied, the latter being represented in the open position. Fig. 2 is a plan view of the attachment in the open position. Fig. 3 is a view illustrating the attachment arranged in its folded or collapsed condition. Fig. 4 is sectional detail view of one of the keepers or clamps designed to be secured to the under side of a table.

Similar reference characters are employed to designate corresponding parts in the several figures where they occur.

As disclosed more particularly in Figs. 1 and 2, the main parts of the attachment are presented by two sections A B, each of which is formed of a series of longitudinal and mu tually spaced slats a 6, connected by battens. These sections A B are pivotally joined together at their bottom edges by hinges 0, located near each end of the sections, the battens cdb being coincidently located for affording proper hold for the hinge-screws. Flexible connections C C, preferably in the form of straps, are secured to both sections A B at their top near each end thereof and limit the relative opening movement of these sections on their hinges.

Short stays (o connecting the slats of the the section A, not only afford additional bracing for said section, but also, provide means for the secure attachment at their upper ends of angularly-shaped irons D, the horizontal members (Z of which are adapted to serve as tongues for insertion and clamping in bearings or sockets presented by keepers E, appropriately located and fastened-on the under side of a sewing-machine table.

The keepers E are preferably in the form of castings and of the general configuration indicated in Fig. 4, involving a central depressed portion e, providing for the bearing or socket, and oppositely-extending Wings 6', containing perforations, countersunk if desirable, for the passage of securing-screws by -which the keeper is fastened to the table.

Revolubly mounted in the portion e is a clampscrew 6 by means of which the member (Z in the socket can be rigidly held against movement.

From the description thus far it will be comprehended that when the members (Z of the attachment are clamped in position beneath the table-top the section A will be supported in a vertically-depending position, and that by reason of the hinge-and-strap connections the section B can occupy a position at an angle to the section A to present a receptacle for receiving work as it passes from the table. With a view, however, of cooperating with the straps C C in sustaining the section B against the strain imposed by the weight of the work, 1 pivotally attach on the battens 7/ externally on the section B legs or supports F F, the connection of which is through the medium of hinges f, so disposed as to permit said legs or supports to assume a vertical position when required or to be folded longitudinally against said section B when the attachment is not being used. 1 may make the free portions f of the legs F F reduced, so that when in the folded position they will overlap and lie closely adjacent to each other, under which conditions they can be retained through the medium of turn-buttons The section B can then be folded up and compactly retained against the section A, by means of aturn-button a centrally at the top of the latter and adapted to be turned to overengage the contiguous seat of the section B. In folding up the section B the straps C C will be caused to fold regularly and lie comparatively smooth by reason of a crimp 0 permanently impressed intermediately in each say, by heat and pressure. By this means thicker and more durable straps can be em ployed than would otherwise be desirable.

From the foregoing it will be appreciated that the novel attachment when in the open position receives all the Work passing from the table, and also prevents such work from becoming entangled in the belt and other parts of the machine below the table. Furthermore, the work is so received and supported that the needle and needle-bar of the machine are relieved from strain.

I do not desire to be understood as limiting myself to the particular construction and arrangement of parts shown and described, but reserve the right to all modifications within the scope of my invention.

Having now described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. In a work-receiving attachment for tables, the combination of two sections hinged together at their lower edges and having flexible connections at their top near each end, one of said sections adapted to occupy an inclined position when the other is vertical, supporting provision pivotally located externally on theinclined section, and means for detachably securing the vertical section at its upper edge to the table.

2. In a work-receiving attachment for tables, the combination of two sections hinged together at their lower edges and having connections for retaining one section inclined while the other is vertical, pivoted legs or supports externally on the inclined section and adapted to fold against the latter closely parallel with" each other, provision for retaining said legs in such folded position, and means for detachably securing the vertical section to a table.

3. In a work-receiving attachment for tables, the combination of two sections hinged together at theirlower edges, and having con nections for retaining one section inclined and the other vertical, pivoted legs or supports externally on the inclined section and adapted to fold against the latter closely parallel with each other, provision for retaining said legs in such folded position, provision for holding the inclined section folded against the vertical section, and means for detachably securing the vertical section to a table.
