APPARATUS FOR HOLDING AND SEWING FABRICS.

SPECIFICATION forming part of Letters Patent No. 460,505, dated September 29, 1891.

Application filed September 22, 1890. Serialll'o. 365,843. (No model.)

To aZZ whom it may concern.-

Be it known that I, RUDOLPH M. HUNTER,

of the city and county of Philadelphia, and

State of Pennsylvania, have invented an Improvement in Apparatusfor Holding and Sewing Fabrics, of which the following is a specification.

My invention has reference to apparatus for holding and sewing fabrics; and it consists of certain improvements which are fully set forth in the following specification, and shown in the accompanying drawings, which form a part thereof.

ments employed for supplying the electricity to the motor, which motor is employed to operate the sewing-machine and cause it to be moved lengthwise with respect to the carpet.

My invention also com prehends certa1n features of construction of support for the carpet or other fabric combined with a railway and traveling carriage supportlng a sewingmachine. These various improvements are set out hereinafter, and particularly specified in the claims.

In the drawings, Figure 1 is a cross-section of an electric carpet-sewing machine on line as a: of Fig. 2, and embodies my invention. Fig. 2 is a front elevation of same. Fig. 3 1s a plan view of the guide-wheels for the extensible conductor, and Fig. 4 is a sectlonal elevation of same on line y y.

A is the table upon which the strips of carpet or other fabric are placed and adgus ted for having their edges sewed together. Ih s table may be of any length desired, and in practice is made very long. Arranged along the floor under one edge of the table is a V shaped rail B, which may act as one of the conductors.

C is a carriage, which is supported upon a large wheel D and a small wheel E, having V-shaped grooves to run upon the rail B, and carries immediately above the axis of the wheel D a sewing-machine H, which is operated by means of an electric motor J and the band K. The wheels D and E are in the same plane, and to prevent the carriage from fall- -ing over and away from the table a grooved guide-wheel E is employed, journaled upon a vertical axis and-running between guiderails G and F secured to the table.

The sewing-machine II is provided with a fabric-guide 1, adapted to receive the edges of the fabric and hold them in relative posi: tion while the needle passes through the fabric. This guide I and the needle are arranged above the wheel D and the rail B, so that the downward strain is directly received upon the rail B. The ordinary feed motion of the sewing-machine, acting upon the carpet, is the means employed for automatically causing the carriage C to travel upon the railway.

L is a resistance-changer for controlling the speed of the motor J, and is preferably arranged upon the carriage C.

S is a source of electric power of any kind, and R is an electric circuit including said source of power and resistance-changer r for controlling the supply of current to the motor. One terminal of the source of power connects with the rail 13, and the current passes through the said railand wheel D and its supporting-frame and by conductor M to one brush of the motor J. The other terminal of the source of power connects with the guide-pulley Q.

N is an upright rod secured to the carriage C and extends to an elevation sufficient to hold the conductor 0 out of reach of persons standing at the edge of the table A. An extensible or flexible conductor 0 is mechanically connected to the upper end of the arm N and extends to the base of the said arm, thence to the resistance-changer L, and from it to the other brush of the motor, and is thereby electrically connected with the electrically-actuated sewing-machine. The conductor 0 passes over a guide-pulley P and between guide-pulleys P, thence overa guidepulley Q, and connects with a weight 'n. The

ICC

guide-pulleys P are grooved wheels and arranged edge to edge and adapted to revolve in a horizontal plane, as shown in Figs. 3 and 4. The guide-pulley P is adapted to rotate in a vertical plane and is journaled in a frame 13, pivoted at p,which is a point between the two wheels P, and is suspended at such an elevation that the upper part of its groove is in line with the groove between the two hori zontal pulleys P, as clearly shown. As the carriage moves along the railway the conductor O is pulled out or given in, permitting the travel of the carriage O and at all times maintaining an electrical connection with the conductor R.

In practice the guide-pulleys P P are arranged in the middle portion of the table with reference to its length, so that in starting the carriage from one end of the railway and moving it to the other end the extensible conductor 0 is first given in, and after the carriage passes the guide-pulleys P P the conductor is drawn out. In practice the conductor O is the positive conductor and the rail B the negative; but this may be varied, if desired.

While I have particularly described my invention with reference to sewing together strips of carpet, I wish it to be understood that my apparatus is equally well adapted for holding and sewing various other fabrics, such as sails, awnings, theater-curtains, (SEC.

It is immaterial to my invention what the nature of the extensible conductor may be, as my invention comprehends any means for maintaining a positive connection with one terminal of the source of power in which the conductor is positively connected with the carriage and is extensible with reference to the source of power.

Having now described my invention, what I 7 claim as new, and desire to secure by Letters Patent, is-
