SEWING-MACHINE.

To all whom t may concern Be it known that 1, CHARLES T. E. GoULD, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sewing-Machines, of which the following is a specification.

This invention relates to improvements in sewing machines, commonly known as the rotary-type, and is particularly intended for use in said class of machines in which a sectional bed-plate is employed, such as is shown and described in lmy application, Serial No. 714,216, filed August 9th, 1912, but I desire it to be understood that I do not wish to be limited in its application or use therewith, as it is applicable to and may be used in connection with various types of sewing machines employing a circularly moving or rotary loop-taker or hook.

The main object of the invention is to provide simple and efficient means for retaining the bc-bbin-case in the rotary hook or loop taker, in such a manner that the former may be more readily inspected, inserted or removed, yet will be securely and properly held in place during operation.

Another object is to provide a holder for the bobbin-case, which when opened, will permit of access to or the removal of the said case from above or either side, yet will afford a support therefor at its bottom and so as to prevent it dropping to the floor or its accidental displacement by rolling to either side.

A further object is to provide means for adjustably supporting the holder for the bobbin-case, in order to allow for the dierence in the sizes of the threads carried by the bobbin in sewing coarse or finer fabrics, as well as for regulating the friction between the holder and bobbin-case when the same is necessary or required.

Still another object is to provide a springactuated locking-bar or lever for the holder which will positively hold it in its closed position, yet will readily allow it to be moved to the desired position for easy access to the bobbin-case.

In the accompanying drawings, which serve to illustrate the invention Figure 1 is a view of the left hand side of a part of the upper portion of a sewing machine, showing the removable cap which covers the bobbincase holder' and cloth feeding mechanism in Specification of Letters Patent.

section. Fig. 2 is a view in side elevation of the left hand portion of the casing located beneath the bed-plate, which casing supports the feed and stitch regulating mechanism, as well as the bobbin-case and its holder. Part of this case is shown as being broken away; Fig. 3 is a vertical sectional view taken on line 3-3 of Fig. 2, looking in the direction indicated by the arrows; Fig. 4 is a plan sectional view of the central portion of the bed-plate of the sewing machine, and Fig. 5 is a detached view of a catch bar used to engage the latch lever of the bobbin holder.

Like numerals of reference refer to like parts throughout the different views of the drawings.

The bed plate of the machine is designated by the reference numeral 10, and may be supported in the ordinary or any well-known way, and has on its upper surface a longitudinally extending head or casting 11, which supports the driving-wheel and needle operating mechanism, which form no part of this invention and are not herein shown. The bed-plate 10, is provided below the upright portion or right hand end of the head 11, with a well or receptacle 12, from which is extended horizontally along the lower surface and longitudinal center of said plate a casing 13, which is substantially U-shapedv in cross-section, and together with said well, forms a covering for the lower operating mechanism of the machine, and at the same time a recept-acle to catch and retain oil drippings therefrom. The outer or left hand end of the casing 13, is provided with a transverse wall 1&1, which has in its lower portion a recess 15, into the upper face of which is threaded a screw 16, which is extended through an opening 17, in a block 18, which has an arm 19, extended outwardly therefrom. The opening 17 is slightly elongated longitudinally to permit of such adjustment of the block 18, and arm 19, the positions of which are controlled by a screw 20, which is fitted in a hole in the wall of the recess 15, and which screw can be properly adjusted before the block 18, is secured in place by the screw 16 employed for said purposes.

Journaled in the wall 14, of the casing 13, and extended in said casing is a rotary shaft 21, which may be connected to and driven by the ordinary or any suitable mechanism (not shown) but usually located in the lower right hand portion of the head 11, and well 12, on the bed-plate. Mounted on the outer end of the shaft 21, so as to rotate therewith is a hook 22, or loop-taker of the ordinary or any preferred kind, in which, the bobbincase 23, carrying a disk bobbin is fitted in the well-known way. The bobbin-case-holder 24, is in the form of a ring and has on its lower portion a pair of spaced apart and depending lugs 25, between which the outer end of the arm 19 is extended. A pivot 2G, connects the lugs 25, and arm 19, so that the holder or ring 24, may have a pivotal movement, as will be readily understood by reference to Fig. 2, of the drawing. The arm 19, has on each of its sides just inwardly of the pivot 26 an upwardly extending abutment 27, against which the lugs 25, will rest when the holder 24, is in its vertical position. l-lorizontally secured to the upper surface of the wall 14, of the casing 13, and projecting outwardly over the rotary-hook 22, and feed mechanism 2S, is a throat-plate 29, which is provided with a number of slots 30, through which the serrated members 31, of the clot-hfeeding-mechanism 23 project to engage the cloth. N ear its outer or free end the throatplate has transversely secured to its lower surface a bar 32, which is provided at each of its ends with a recess 33, to receive horizontally extended and inwardly projected flanges 34, on the upper portion of the sidewalls of a removable cap 35, which is fitted to the outer end of the casing 13, and incloses the cloth-feeding mechanism, rotaryhook and bobbin-case holder, as will be understood by reference to Figs. 1 and 4 of the drawing.

llhe bar 32, is provided at about its middle in its outer edge with a recess 36, which has at one end thereof a catch 37, for the reception and retention of the upper portion of a latch-bar 33, which is pivoted at its lower end to the lower portion of the ring or holder 24, and has near its upper end a laterally eX- tended arm or finger piece 39, by means of which it can be pressed out of engagement with the catch 37, of the catch-bar 32. The upper portion of the holder 24, is provided on its outer surface with a loop 40, which embraces the latch-bar and acts as a guide therefor.

A spring 41, fastened at one of its ends to the loop 40, and restingl at its other end against the bar 3S, serves to press said bar and to hold it in engagementl with the catch 37, of the catch bar, thusretaining the holder or ring 24 in its upright or closed position around the bobbin-case. When access to the bobbin-case is desired, the cap 35, is removed, when by pressing the latch-bar 38 in the proper direction it will be disengaged from the catch-bar 32, thus permitting the holder 2-A to be turned to about the position shown in Fig. 2, so that the bobbin-case can be removed, inspected or inserted.

Having thus fully described my invention what I claim as new and desire to secure by` Letters Patent is In a sewing machine, the combination with a bed-plate having a hollow casing on its lower surface and provided with a throat plate at the outer end of said casing, of a revoluble shaft located in said casing and extended below said plates, a bobbin-case carried by said shaft, a bar located on the throat plate and having a portion recessed to form a catch, an arm adjustably secured to the lower portion of the case, a circular holder pivotally mounted at its lower portion on said arm and provided with a guide loop on its outer surface, and a latch-bar pivotally connected to the holder and eX- tended through the loop thereon and adapted to engage the catch of the catch bar.
