FAN ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 485,554, dated November 1, 1892.

Application filed November 4, 1891. Serial No. 410,867. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE W. MILLER, a citizen of the United States, residing at Bryan, in the county of Brazos and State of Texas, have invented a new and useful Fan Attachment for Sewing-Machines, of which the following is a specification.

The invention relates to improvements in fan attachments for sewing-machines.

The object of the present invention is to provide a simple and inexpensive fan attachment for sewing machines, adapted to be readily applied to a machine and capable of fanning an operator effectively without interfering with the work of the machine.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended.

In the drawings, Figure 1 is an elevation of a sewing-machine table provided with a fan attachment constructed in accordance with this invention. Fig. 2 is a sectional view on line w w of Fig. 1. Fig. 3 is a detail sectional view.

Like numerals of reference indicate like parts in all the figures of the drawings.

1 designates a sewingmachine table or stand having depending from its rear edge a casing 2, which is provided at its top with slotted arms 3, arranged on opposite sides of the casing and extending beneath the top of the table or stand 1 and secured to the same by screws 4, passing through the slots, whereby the casing is adjustably attached to the stand. The casing 2 hasjournaled in its sides a horizontal shaft 5 and in its top an inclined shaft 6, which is connected with the horizontal shaft by beveled gear 7, and which has its lower end journaled in a bracketplate 8, extending horizontally from one side of the casing and having its upper face inclined. The horizontal shaft extends beyond one side of the casing and carries a pulley 9, which is connected by a strap with a ring 10, detachably secured to the drive-wheel 11. The inclined shaft is arranged in a cylindrical extension 12 of the casing and is proprovided in their peripheries with V-sh aped grooves to receive a strap which conveys motion from a drive-wheel to the horizontal shaft. The ring is attached to one side of the drive-wheel by hooked bolts 15, which are arranged in slots 16 of enlargements 17 and engage spokes of a drive-wheel and are provided with nuts, whereby a ring is detachably secured to the drive-wheel.

The bolts 15 have semicylindrical stems and are arranged in pairs with their hooks engaging opposite sides of the spokes. By this construction the ring may be readily adjusted on the wheel.

The inclined shaft 6 is prevented from rising and the horizontal shaft 5 is held against longitudinal movement by

collars

18 and 19, which are arranged on said shafts and located adjacent to the casing and provided with setscrews for securing them to the shafts.

From the foregoing description and the accompanying drawings the construction, operation, and advantages of the invention will be readily understood.

What I claim is Afan attachment for sewing-machines, comprising a casing provided with horizontallydisposed slotted arms and secured to a sewing-machine adj ustably by bolts arranged in the slots, said casing being provided at its top with an incline cylindrical extension, 2. horizontally-extending bracket-plate arranged within the casing and projecting from one side thereof and having its upper face inclined, an inclined shaft journaled in the bracket-plate and in the inclined extension and provided with a fan-socket, a horizontally-disposed shaft journaied in the sides of the casing, beveled gearwvheels connecting the shafts, and a pulley mounted on one end of the horizontal shaft and arranged. outside of the casing and connected with a drivewheel of a sewing-machine and with a horizontal shaft, substantially as described.

In testimony that I claim the foregoing as my own I have hereto aifixed my signature in the presence of two Witnesses.

GEORGE W. MILLER.
