FAN ATTACHMENT F'OR SEWING-MACHINES, 84.0.

SPECIFICATION forming part of Letters Patent No. 615,802, dated December I3, 1898.

Application filed March 31, 189 8.

T at whom it may concern:

Be it known that I, THOMAS J. BUTLER, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Fan Attachments for Sewing-Machines, &c.; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention has reference to a novel form of fan attachment for use in connection with sewing or other machines; and the invention has for its primary object to provide a novel arrangement for supporting the fan mechanze ism upon the table or support of the machine,

and also to provide a novel means for operating the fan from the machine or fly-wheel of the machine.

A further object of this invention is to provide, in connection with the fan-operating mechanism, a means of adjustment for operatively bringing a friction wheel or disk on the fan-shaft against the periphery of the flywheel of the sewing-machine orother machine with which the invention is connected.

The principal purpose of the invention is to provide a simple and effective device-for the objects above stated which can be quickly and easily applied to any kind of machine 5 and can be driven from the machine-wheel or the fly-wheel thereof and when in operation resulting in great comfort to the operator.

The invention therefore consists in the novel construction of fan attachment for sewo ing-machines and other machines to be hereinafter fully set forth, and also in such novel arrangements and combinations of parts, all of which will be described more in detail in the accompanying specification and finally 5 embodied in the clauses of the claim.

The invention is clearly illustrated in the accompanying drawings, in which--- Figure 1 is a front elevation of my novel construction of fan attachment for a sewing or other machine, a portion of such machine being represented to illustrate the application Serial No. 675,839. (No model.)

of the invention to the same. Fig. 2 is an end view of the fan attachment, and Fig. 3 is a top view of the same. Fig. 4 is a horizontal section taken on linear in Fig. 1, and Fig. 5 is a similar View taken on line y in Fig. 2. Fig. 6 is a perspective view of a slide forming a bearing for the fan-bracket.

Similar letters of reference are employed in all of the above-described views to indicate corresponding parts.

In said drawings, 17 indicates a portion of any one of the well-known sewing-machines, and b is the fly-wheel thereof, which is driven from the belt b A indicates the complete fan attachment, the same comprising a suitable pedestal or support 0, having legs a and perforated flanges or lugs a for the reception of screws a by means of which said pedestal is securely 7o fastened in place on the table or'bed b of the machine at the proper distance to one side of the machine-wheel or the fly-wheel of the latter. The upper part a of said pedestal has a vertical slot a and apair of rearwardlyprojecting flanges a", forming suitable guides, between which I have arranged a verticallyadjustable slide or block 0, which is more clearly illustrated in Fig. 6. Said slide or block 0 consists of a rectangular portion 0, in which there is an oblong opening 0 and has an upwardly-projecting arm 0 which is provided at or near the top thereof with a hole 0 said arm c also having a stud or arm 0 extending at a right angle, or appro'xi- 8 5 mately so, from one edge of the said arm 0 as will be more especially seen from an inspection of Figs. 1 and 6. Said arm or stud c is also provided with a circular hole a. In order that the said slide or block 0 may be 0 adjustably secured between the said flanges a of the part a of the pedestal a, I employ a bolt cl, the head d of which is arranged against the back of the slide or block 0, and

the threaded shank (l of said bolt being 5 passed through the oblong hole or opening 0 in the slide and through the slot a of the part a of the pedestal a, so that said shank projects from the side of said part a and is adapted to receive a suitable nut or thumb- 10o screw d for securely holding said block or slide in its properly-adjusted position be tween the said guides of the pedestal, as will placed a series of balls or rollers 6 thereby forming ball-bearings for a spindle a, carrying the fan 6 The opposite ends of said spindle e are screw-threaded, and upon each threaded end of said spindle I have screwed one of the cones e so that the cone-surfaces of said cones will be brought in rotative engagement with the said balls or rollers e in the usual manner of the construction of ballbearings and as will be clearly seen from said Fig. 4. The cone 6 on the'right-hand end of the spindle is retained in its adjusted position by a lock-nut while the cone 6 is held in position upon the other end of said spindle e by a lock-nut c", the hub of the fan e being arranged and secured in position on this end of the spindle between said nut e and the said cone, as clearly illustrated in said Figs. 1, 3, and 4c. The end of the said spindle a may be socketed, as at e said socket being in communication with the usual hollow portion of the spindle e for the reception of lubricating-oil and a stud f being employed as a finish and to close the end of the spindle, said stud having spring-fingers f, adapted to be forced into said socket for holding the said stud in position against the end of the spindle. Adjustably secured upon the spindle a between the two arms or bearing portions e, by means of a set -screw g, is a wheel g, having a grooved peripheral surface in which there is a soft ring of rubber or othersuitable material, which is to be brought in frictional contact with the periphery of the fly-wheel or machine-wheel b, substantially as and for the purposes to be hereinafter fully explained.

As will be more especially seen from an inspection of Figs. 1 and 2, the said yoke or U- shaped frame 6 is formed with a downwardlyextending arm e, which is perforated, as indicated in dotted outline at e in said Fig. 1, and also has a short ear or lug 6 extending at a right angle therefrom, or approximately so, said ear or lug being provided with an oblong hole e, as indicated in dotted outline in said Fig. 2. The said frame 6 and the parts connected therewith can thus be pivotally connected with the arm a of the slide or block 0 by means of a bolt or pin h, which is passed through the hole 6 in the arm a and the hole 0 in the arm 0 and by means of a nut or thumb-screw it said parts can be then secured together in their properly-adj usted positions. When these parts have been connected in this manner, a pin or bolt '2; is passed through the openings in the oppositely-placed ears or lugs e and c on the respective arms a and c, the bolt 'Lbeing pro= vided with a head 'i and a flattened part in said oblong hole 6 in the ear or lug e and having its screw-threaded end 1' extending into and through the perforated ear or lug c of the arm 0 A tension-spring is made to encircle said pin or bolt 2' on that portion between said ears or lugs e and c and upon the threaded and free end of said bolt 1' is a thumb-screwt, which after the block or slide a has been properly adjusted in the guide portion of the pedestal a to bring the friction-wheel g on the spindle e in close proximity to the periphery of the fly-wheel b is then screwed up tight. The said frictionwheel 9 will thereby be caused to more firmly engage with the said fiywheel I), and the several parts of the fan attachment are then secured in such adjusted positions by tightly screwing up the nut or thumb-screw h on the pin or bolt h to prevent any pivotal motion of the said frame or yoke e on the said arm a of the slide 0. In this manner when the machine I) is operated the machine-wheel b will cause the operative engagement of the wheel g, and in consequence thereof the rotation of the spindle e and the fan to the great comfort of the person operating the machine.

As will be seen more especially from Figs. 1 and 3, the spindle e and its fan are preferably arranged at an angle to the longitudinal edges of the table or bed of the machine, whereby when the fan-blades are set in motion the cool air is forced directly toward the person sitting at the front of the machine; but this arrangement is not an absolute necessity, as will be clearly understood.

To disengage the friction wheel or disk 9 from its operative engagement with the flywheel of the machine, a slight turn of the thumb-screw h and the thumb-screw 2'" will permit the spring 2' to exert its force against the ear or lug 6, whereby the frame or yoke 6 will swing on the pivotal pin it and the wheel 9 will be moved away from its operative contact with the periphery of the machine-wheel b. The several parts of the fan bracket E can then be held in such inoperative position by once more screwing up the thumb-screw h, as will be clearly evident.

Of course I am fully aware that many changes maybe made in the several arrangements and combinations of the several parts and in the details of the construction thereof without departing from the scope of my pres ent invention. Hence I do not limit myinvention to the exact arrangements and combinations of the parts described in this specification and illustrated in the drawings, nor to the exact details of the construction thereof.
