ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 794,655, dated July 11, 1905.

Application filed august 2'7, 1904. Serial No. 222,433.

To a whom it may concern.-

Be it known that I, J ACKSON THOMAS BEAR- DEN, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented a new and useful Attachment for Sewing-Machines, of which the following is a specification.

This invention relates to attachments to sewing-machines whereby the rotative motion of the needle-bar shaft may be utilized for operating an air-circulating fan, a drill, or other implement or device, and has for its object to produce a simply-constructed device of this character which may be applied to the machine without change in the structure of the same or interfering in any manner with its ordinary uses.

With these and other objects in view,which Will appear as the nature of the invention is better understood, the same consists in certain novel features of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which corresponding parts are denoted by like designat ing characters,is illustrated the preferred form of the embodiment of the invention capable of carrying the same into practical operation, it being understood that the invention is not necessarily limited thereto, as various changes in the shape, proportions,and general assemblage of the parts may be resorted to without departing from the'principle of the invention or sacrificing any of its advantages.

In the drawings thus employed, Figure 1 is aside elevation, partially in section; and Fig. 2 is a rear elevation of a portion of the head or arm of a sewing-machine with the improved device applied.

The head or needle-arm of a sewing-machine is represented at 10, with the outer end of the needle-operating shaft at 11 and the band-wheel and fly-wheel, respectively, at 12 and 35 of the usual form.

The improved device comprises a shaft or bar 13, having a transverse socket 14 for encompassing the enlarged rear end 15 of the shaft 11 and provided with a set-screw 16 for bearing against the enlarged end to hold the same firmly in position and likewise maintaining the bar 13 in position in longitudinal alinement with the shaft 11.

The outer end of the shaft 11 is provided with a chuck 17 for receiving and supporting a drill or other similar implement 18 and provided with a set-screw 19 to hold the socket firmly in place.

Adjustably disposed upon the shaft 13 is a hub 20', having a set-screw 21 for holding it in position and also provided with radiating rods 22.

Each of the rods is provided with an adjusting-nut 23 on the outer end for bearing against a fan blade or wing 84, carried by the rods and rotatively adjustable thereon. By this means the fan-blades may be adjusted to any desired pitch upon the rods or reversed in position, as may be desired. The fan may thus be set to project the air in either direction and with any desired force or detached entirely, if required.

It will thus be noted that a very simply-constructed and easily-a pplied device is produced, which may be quickly attached or detached and operated by the treadle of the machine and without injury to the latter or interfering with the ordinary operation of the same. The fan will thus maintain strong air-currents across the machine, which will be very refreshing to the operator, as will be obvious. At

the same time the shaft 13 may be utilized to the presence of two witnesses.
