SEWING-MACHINE TABLE.

SPECIFICATION formingpart of Letters Patent No. 683,499, dated October 1, 1901.

Original application filed April 15, 1898, Serial No. 677,728. Divided and this application filed January 5, 1900. Serial 170.431. (No model.)

To all whom it may concern.-

Be it known that I, HUBERT P. RICHARDS, a citizen of the United States, residing in New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Sewing-Machine Tables, of which the following is a specification.

This invention relates to sewing-machines, and more particularly to an improved organization in which the sewing-machine head is supported on the table for tilting movement, the object of the invention being to provide an improved connection between such table and head.

A further object of the invention is to provide, in connection with a sewing-machine table having an opening for the head of the machine, a bracket secured at its rear end to the table and having at the forward end thereof a particircular hinge member or socket disposed within said opening and a sewing-machine head having a slabbed or particircular pintle seated in said socket and forming in connection therewith a separable hinge-joint.

In the drawings accompanying and forming part of this specification, Figure 1 is a plan view of a portion of a sewing-machine embodying my present improvements. Fig. 2 is a front elevation, partially in section, of a portion of a sewing-machine such as is illustrated in Fig. 1. Fig. 3 is an end view, partially in section, illustrating the improved means for supporting the head for tiltable movement. Fig. 4 is a rear elevation thereof, partially in section. Fig. 5 is a view similar to Fig. 3, showing the head of the machine tilted back to an inspecting position.

Similar characters of reference designate like parts in all the figures of the drawings.

The present improvement comprises a table (designated in a general way by T) and a sewing-machine head, (designated in a general way by H,) said head and table having an improved connection to permit the tilting of the head relatively to said table. This improved table comprises in the preferred form thereof, (shown in part in the accompanying drawings) two table-supporting uprights 2 and 3, of some suitable construction, and a table-top 4, having an elongated opening 4 for the head of the machine, which opening is shown of a length somewhat greater than the length of the bed-plate 8 of the sewing-machine head and extends somewhat in advance of the needle-bar end of said head, as is shown most clearly in Figs. 1' and 2 of the drawings. By extending the opening 4 for the sewing-machine head somewhat beyond the fabric-supporting end of the bed-plate of said head certain parts of the looper mechanism and feed mechanism may be readily inspected without tilting the sew ing-machine head backward, and this further facilitates the easy handling of certain kinds of work during the operation of sewing-as, for instance, such work as could not be conveniently supported upon that portion of the table-top contiguous to the fabric supporting and feeding end of the sewing-machine head while being operated upon.

For the purpose of bridging the opening between the fabric-supporting end of the bedplate of the sewing-machine and the opposite edge of the table-top'I have provided a dropleaf L, the particular construction of which forms the subject-matter of a separate application, Serial No. 34,257, filed October 25, 1900. Therefore only a general description thereof is deemed necessary herein. This leaf is shown at 5 hinged to the edge of said table, (see Fig. 2,) and which drop-leaf is provided with a spring-actuated dctent or latch Z for normally engaging the table and holding the drop-leaf in its elevated or horizontal position. vided near the hinged edge thereof with a depending arm 6, the outer free end of which bears against a leaf-lifting spring 7, secured at one end to some suitable fixture forming part of the table, it being shown herein fixed to the end wall of a drawer-cabinet cl, depending from the table-top 4. This arm 6 and the spring 7 are so constructed and are so disposed relatively to each other that when the leaf L is in a vertical position said spring will tend to retain the leaf in this position, but will when said leaf is moved to a position slightly at one side its vertical position exert This drop-leaf is shown proan upward thrust upon the arm 6 and lift said leaf to its normal position, as will be readily understood by reference to said Fig. 2. To permit the leaf to be dropped, a recess 6 is provided in the table-top 4 for the entrance of the free end of the arm 6, the upper end of the spring also projecting in to such recess, whereby the two members 6 and 7 are in permanent engagement.

The head H of the sewing-machine, which head may be of any suitable general construction, is shown embodying a bed-plate 8, having depending front and rear flanges 9 and 10 and

end flanges

12 and 13, which meet at their ends and form a hollow and bottomless casing for that portion of the stitch-forming mechanism disposed below the bed-plate H. The sewing-machine head will in practice he provided with stitch forming mechanism, which may be of any suitable construction and organization. Only a portion of this 'mechanism is shown in the accompanying drawings, for the reason that it is inessential to the present invention.

As a means for tiltably or pivot-ally supporting the sewing-machine head at a point remote from the rear edge of the bed-plate thereof in such manner as'to permit the ready removal and replacement of said head I have provided, in connection with the table T, preferablytwo head-supporting brackets (designated in a general way by B and 13') provided at the forward ends thereof with particircular or transversely-slotted hinge members or bearings 14 and 15, respectively, and I have provided, in connection with the end flanges l2 and 13 of the sewing-machine head, two inwardly-projecting slabbed or

particircular pintles

16 and 17, adapted to be slipped into operative position within the hinge members or bearings 14 and 15, the

f construction and organization of saidpintles and bearings being such that when the head of the machine is in the position shown. in Fig. 3 it may readily be disengaged from its supports by lifting the same upward, which will draw the pintles out of the bearings through the slots thereof, as will be readily understood by reference to Figs. 3 and 5 of the drawings.

It will be seen by reference to Figs. 3 and 5 that the piutles are cut away or slabbed on their front and rear faces; that the hinge member or hearing of each of the brackets, as B, has a portion of its upper wall cut away to form a slot to permit the entrance of said pintles; that when the sewing-machine head is in the position shown in Fig. 3 the lower circular face of each pintle has a cooperative bearing engagement with the inner circular wall of the bearing, and, further, that when the sewing-machine head is tilted backward to a position shown in Fig. 5 both curved faces of the pintle cooperate with opposing interior portions of the bearing and lock the head against removal when in this position.

Each bracket in the preferred form thereof shown in the accompanying drawings has downwardly, forwardly, and upwardly extending portions, {designated by 18, 19, and 20, respectively,) the latter of which terminates within the opening 4 in the table-top considerably in advance of the rearward edge thereof and the former of which has a rearwardly-extended bar whereby the same may be secured to the table, preferably by screws. (Shown in dotted lines.)

By reference to Figs. 3 and 5 it will be seen that the sewing-machine head is hinged or pivotally supported somewhat remote from the rear edge of the bed-plate, so that when said head is tilted to an inspecting position (shown in said Fig. 5) the rear edge of said bed-plate will extend considerably below the pivotal point of said head, and as a means for limiting the tilting movement of said head and for holding the same when in a tilted position out of contact with the rear portion of the table I have provided,in connection with each headsupporting bracket, a stopabutment 19', which is shown formed on the intermediate or forwardly extended portion 19 of said bracket at a point substantially midway between but considerably below and in the rear of the pivotal point of said head, said abutment being disposed in the path of movement of the rear portion of the bed-plate 8.

As a means for locking the sewing-machine head in its working or normal position I have provided a locking device, (designated in a general way by P,) which locking device, in the preferred form thereof shown in the accompanying drawings, comprises a springactuated bolt 30, supported for reciprocatory movements in a bearing 31, formed in a boss on the front flange of the bed-plate and having a conical locking portion or head 32, adapted toclosely fit a socket formed in the face of the table-top 4:, as will be readily understood by reference to Fig. 3 of the draw ings, a spiral spring 33, bearing at one end against the headed end of the bolt and at its opposite end against the rear wall of the bearing, forcing the conical portion of the head into said socket and holding the sowing-machine head against any accidental vibratory movement, and as ameans for shifting' the bolt to an inoperative position and for locking the same in this position I have provided, a bolt actuator, which is shown herein as a vertically-disposed pin 35, fixed at its lower end to the headed end of the bolt and extending through a vertical slot in the bed-plate, the outer end of said pin being furnished with a head or thumb piece 35, whereby said pin and bolt may be manipulated. The slot through which this pin extends will in practice preferably be of such form that the pin may be turned to a posi- IIO tion whereby the wall of said slot will hold the same in either of its adjusted positions, so that the bolt may be locked in an advanced or retracted position.

Having described my invention, I claim 1. Thecombination,with asewing-machine table having an opening for the head, of a bracket secured at one end to said table and having its opposite end terminated within the table opening remote from the rear edge thereof and also having a stop-abutment intermediate its ends, and a sewing-machine head pivotally supported at a point remote from its rear edge on said bracket, the construction and organization being such that on the tilting of said head backward the rear edge of said head will extend considerably below its pivotal point and engage the stopabutment of said bracket, which limits the tilting movement thereof.
