UNITED STATES PATENT ALBERT H. IDE VOE, OF WESTFIELD, NEW JERSEY, ASSIGNOR TO THE SINGE MANUFACTURING COMPANY, A CORPORATION OF NEW JERSEY.

DRIP-PAN FOR SEWING-MACHINES.

Specification of Letters Patent.

Patented Apr. 1, 1919.

Application filed February 17, 1917. Serial No. 149,371.

To all whom it may concern:

Be it known that I, ALBERT H. DE Von a citizen of the United States, residing at Westfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Drip-Pans for Sewing-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a power table for sewing machines and more particularly to a drip-pan support for machines having their main-shaft located between the throatplate or work-supporting surface and a bedlate.

lVith the object of clearing the fabric supporting surface on all sides of the needle so that an operator may handle fabric with great facility this invention provides for the location of the throat-plate, cloth-plate and table-top in substantially the same plane. With the object of affording ready access to the lower thread-handling mechanism of a sewing machine as well as facilitating the removal of such machine from the table when occasion demands, it provides for shifting the cloth-plate to expose the entire bed-plate of the machine. And with the object of preserving a sufficient mechanical advantage to enable an operator to manipulate a knee-shift device against the resistance offered by certain movable elements of a sewing machine, such as a presser-foot or multiple tension device, it provides a location and arrangement of the knee-shift device above the bottom of the drip-pan.

To the attainment of these ends a power table is provided with a pair of brackets secured to opposite sides of the table at the opposite ends of a recess provided in the table. A drip-pan. is secured to the brackets by fastening-bolts which pass through vertically arranged slots that permit the drippan being adjusted to different elevations. The drip-pan which is stiffened with sultably disposed ribs and provided with lugs for seating a sewing machine clear of the A knee-shift lever is thread-handling mechanism. The rear cover-plate is removably fitted to the recess in the table and is cut away to conform to the outlines of the throat-plate and vertical standard of the machine. The front coverpllate is provided with a depending apron lling the gap made by the recess in the front edge of the table-top and is supported on horizontal pivots formed by pinning together pairs of lugs extending forwardly and rearwardly respectively from the front side of the drip-pan and apron. A spring is secured to the front side of the drip-pan adjacent one of the pairs of lugs and acts on the toe of a lug carried by the apron to yieldingly hold the front cover-plate in normal operative position.

The invention further consists in certain details of construction which will appear from the following description of the device shown in the drawings, in which Figure 1 is a perspective View of the drip-pan supported by the brackets secured to the table which is indicated by dotted lines. Fig. 2 is a longitudinal section in a vertical plane passing through the line AA Fig. 1 and Fig. 3 is a transverse section taken in a vertical plane containing the line BB, Fig. 1, with the front half section of the cloth-plate in normal position.

In a power-table bench 1 of any suitable material, preferably wood, a recess 2 is formed in any convenient way, a portion 3 extending from its front edge into proximity to its rear edge being left to preserve as much as possible the desirable appearance of a wooden finish on the front edge of the table. A sewing machine 4, seated upon a drip-pan 5 supported below the table-top by brackets 6 and 7, is positioned within the re cess with its throat-plate 8 substantially in the plane of the table-top, and with its lower-thread handling mechanism 9 and bedplate 10 entirely inclosed by a cloth-plate, comprising a rear half-section 11 removabl y seated on the edges of the recess 2 and a front half-section 12 having a depending apron 13 hinged to the drip-pan.

Pairs of spaced lugs 14 and 15 on the rear of the apron and front of the drippan, respectively, are connected by horizontally arranged pins 16 and afford means for moving the front half-section from a position above the lower thread-handling mechanism to a position fully exposing the same for re- 11 to embrace the throat-plate 8 with which operators knee.

it is flush.

The drip-pan 5, which i suitably stiffened with ribs 5 and provided with tapped lugs 5 sustaining the bed-plate clear of the bottom of the pan, as previously mentioned is supported from the brackets 6 and 7.

Bracket 6 at the left end of the recess comprises a horizontal portion 20 drilled as shown for wood-screws holding it to the bottom of the table-top, and vertically disposed flanges 21 and 22 (Fig. 1) provided with apertures 28 for the fastening-bolts 23 threaded into the drip pan, said flanges being at right angles to each other and located substantially in parallelism to the end and rear side walls of the recess in the table.

The bracket 7 at the other end of the recess is U-shaped and is located with its horizontal extension 24 resting on the end and side walls of the recess so as to reinforce the wood at this point as well as distribute over a relatively large area of the wood the weight of the parts and the strain from the driving belt which is adapted to pass through the slot 5 over the pulley 4. Vertical flanges 25 of the bracket 7 are adapted to receive fastening-bolts 26 passing through apertures 27 in the drip-pan. The several apertures 27 and 28 are elongated vertically to provide an adjustment which admits of accurately locating the drip-pan and nicely setting the throat-plate of the machine flush with the table-top to compensate for slight differences in either the sewing machine or dripan. p Viewed as in Fig. 1, the drip-pan resembles an open box. It is preferably of rectangular shape with low sides and ends. J ournaled in its sides and extending across and above the bed-plate of the machine is a rockshaft 30 from which at its forward end depends an arm 31 in convenient reach of an At its rear end the shaft is provided with a finger 32 for lifting one end of a lever 33 pivoted at 34: to the rear side of the drip-pan and adapted to be connected at its other end by a reach rod 35 or other suitable means to one or more movable elements of the sewing machine, such as a presser-foot lifting lever or multiple tension device, not shown. The rock-shaft at its rear end also carries a second finger 36 which is shaped to engage the edge of the rear side of the drip-pan and limit the movement of the rock-shaft in a direction opposite to that in which it is turned'when actuated by the operator. The fingers mentioned may be formed upon the shaft in any suitable manner but preferably as shown they are made integral with a disk 37 secured by a set screw 38 to the shaft.

- The horizontal extension 24 of the bracket 7 is provided with an apertured boss 24: to which is adapted to be secured a combined tape-reel and multiple cop-arm, which are not shown in the drawings as they are to be made the subject matter of another application.

Having thus set forth the nature of the invention, what I claim herein is:
