FAN ATTAC HM EN SPECIFICATION forming part of Letters Patent No. 743,548, dated November 10, 1903. Application filed June 20. 1903. Serial No. 162321. (1% model) To all whom it may concern.-
Be it known thatl, WILLIAM G. NORMAN, a citizen of the United States,residing at Smithton, in the county of Clark and State of Arkansas, have invented certain new and useful Improvements in Fan Attachments, and par-' ticularly in my fan attachment described in Letters Patent No. 719,688, dated February 3, 1903; and I do declare the following to be a full, clear, and exact descriptionof 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 ac companying drawings, and to the. figures of reference marked thereon, which form a part of this specification.
My invention is a fan attachment to sewing-machines, with mechanism for driving the same in connection with the band mechanism of the machine; and it consists of the mechanism hereinafter described.
In the accompanying drawings, Figure 1 is a rear elevation of a high-arm sewing-machine with my invention attached thereto. Fig. 2 is an end view of Fig. l. detailed view showing the base part of my frame clamped to the table of a machine instead of being screwed thereto.
My invention is described as follows:
Fig. 1 represents the rear elevation of a high-arm sewing-machine, in which 1 represents the arm; 2, the plunger-frame; 3, the
plunger; 4, the needle-holder; 5, the bandwheel 6, the band; 7, the balance wheel, and 8 the standard by which the machine is secured to the table. Mounted on the table and in rear of the standard 8 is a framework 9, which may be described as an inverted L, with a projected bearing 10 at its angle to accommodate a shaft. The base of this L- shaped frame 9 may be secured to the upper face of the table by screws 12, or it may have an extended arm 13, which may extend outwardly and then downwardly and then back under the arm 13, thus forming an under arm 14, which may be perforated about midway its length and provided with a thumb-v screw 15 for securing it to the table. The
Fig. 3 is a tended feet slots 21, through which Work screws 22, by means of which the said hearing is adjustable, and journaled to itsvfree end is a pulley 23, by means of which the band'may be tightened or pressed up against the drive-pulley 18. Secured horizontally to the'extended bearing 10 of the frame 9 is a shaft 11, and on this shaft are journaled two pulleys 24 and 25. The horizontal arm of the frame 9 extends along and to the rear of the frame 1 until it nearly reaches the plungerframe 2, then it turns upwardly, terminating in a bearing 26, and in this bearing 26 is secured a shaft 27, and journaled on this shaft 27 is a pulley 28, and journaled on the same shaft and rigidly secured to the front face or the pulley 24 is a fan-wheel 29. This fan-wheel may be secured by means of a pin 30 (see Fig. 2) or by any other means. Working around the drive-pulley 19 is a band 31, which runs upwardly and over the two pulleys 24 and 25 and then horizontally and around the pulley 28. The purpose of the two pulleys 24 and 25 is to keep the band from contacting at this point. If the band was not separated here by the two pulleys, there would be friction, as the band runs in opposite directions at this point. The fan-wheel 29 is removable and may be removed at any time, if desired, and so may the entire attachment. The fan normally turns to the right, but by crossing the band 31 it may be made to turn to the left. If I do not want the fan turned, I loosen the screws 22 and pull the bearings 20 back until the pulley 23 does not touch the band 6, and thus becomes an idler. All the pivotal points in my attachment may be ball-bearing.
The operation of the fan is apparent.
This attachment is primarily intended for sewing-machines, but may be attached to any machinery so constructed that it may be operated in connection therewith, and I therefore claim this attachment for all purposes to which it may be applied.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. A sewing-machine attachment consisting of a frame substantially in the shape of an inverted L, secured to the upper face of the table of a sewing-machine in rear of its standard 8; a shaft 17, secured in the vertical arm of the said frame 9; a drive-pulley 18, journaled on the outer end of said shaft and adapted to contact with the band 6, of the sewing-machine; a drive-pulley 19, journaled on said shaft 17, near the upright arm of the frame 9; a bearing 10, projecting upwardly from said frame; a shaft 11, secured horizontally to said bearing and journaled on said shaft- pulley 24, and 25; a bearing 26, rising vertically from the horizontal arm of the frame 9; a shaft 27, secured horizon- 2. A sewing-machine attachment consisting of a frame substantially in the shape of an inverted I L, secured to the upper face of the table of a sewing-machine in rear of its standard 8; a shaft 17, secured in the vertical arm of the said frame 9; a drive-pulley 18, journaled on the outer end of said shaft and adapted to contact with the band 6; of the sewing-machine; a drive-pulley 19, journaled on said shaft 17, near the upright arm of the frame 9; a bearing 10, projecting upwardly from said frame; a shaft 11, secured horizontally to said bearing and journaled on said shaft- pulleys 24, and 25; a bearing 26, rising vertically from the horizontal arm of the frame 9; a shaft 27, secured horizontally to said bearing; a pulley 28, journaled on said shaft; a fan 29, journaled onsaitl shaft and secured to said pulley,and an L-shaped bearing 20, adj ustably secured to said table and pulley 23, journaled on said bearing and adapted to contact with the band 6, of the sewing-machine, substantially as shown and described and for the purposes. set forth.
In testimony whereof I affix my signature in presence of two witnesses.
WILLIAM C. NORMAN.
