IMPROVEMENT IN SEWING-MACHINES.

Speciiication forming part of Letters Patent No. 145,287, dated December 9, 1873; application filed November 1, 1873.

To all whom it may concern:

Be it known that we, JOHN FANNING and -EnwAEn NUGENT, of the city of Brooklyn, in

hitherto made.

It is well known among operators that a great difficulty exists in adjusting this class of machines to different kinds and sizes of thread,

andy prevent dropping stitches. This objection is entirely avoided in our machine.

r1 he following is a full and exact description of our machine, reference being had to the accompanying drawings and to the letters of reference marked thereon, in which- Figure 1 is a top view of our machine. A is the needle-bar. B is the pressure-foot bar. O is the tension for tf e upper thread. D is the ten sion for the lower thread.

Fig. 2 is a side elevation of our machine. E is the under or horizontal needle. F is a screw passing through a slot in the bar G intovthe end of the needle E, to enable the operator to H is an oscilla-ting bearing or guide for adjusting the needle sidcwise. I is the driving-shaft. J J are beveled gear-wheels, giving motion to an eccentric, K, which drives the under needlebar G. This oscillating bearing is composed of a plate, o, having a pin or journal secured in the forward bearing of the main shaft, and adjustable by means of a screw, h, so as to place the needle E in proper relation with the vertical needle; and at top of plate o is a pivoted block, i, having a hole to receive and guide the needle steadily.

Fig. 3 is an elevation of the back end of our machine, showing the eccentric L, which gives motion to the upper needle-bar, communicating said motion through the arm N.

Fig. 4 is a front-end elevation of our machine, in which M is the feed-bar.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

The oscillating adjustable guide H, constructed as described, in combination with the eccentric K, bar G, and needle E, operating in connection with an eye-pointed perioratingneedle, as and for the purpose described.
