FAN ATTACHMENT FOR SEWING-MACHINES.
SPECIFICATION forming part of Letters Patent No. 269,669, dated December 26, 1882.
Application filed July 26, 1882.
1'0 all whom it may concern:
Be it known that I, ANSON HILGER. a citizen of the United States, residing at Pierre, in the county ofHughes and Territory ot Dakota, have invented certain new and useful Improvements in Fan Attachments for Sewing -'Machines, 850.; 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 appertainsto make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.
This invention relates to a fan attachment for sewing-machines, tables, desks, and similar articles of furniture; and it consists in the construction and arrangement of devices for producing a current of'air and in the manner of attaching and operating said mechanism, as will be hereinafter more fully described and claimed.
1n the annexed drawings, which illustrate my invention, Figure 1 is a side view of the fan and operating mechanism, showing the manner of connecting the supporting-standard to the table of a sewing-machine. Fig. 2 is a view of the same, taken at a rightangle to Fig. 1. Fig. 3 is a perspective view ofthefan and connected spindle. Fig. 4 illustrates the mannerin which the wheel or pulley over which the driving-belt is passed may be connected with or applied to a wheel on any machine desired. Fig. 5 represents an arrangement of gearing for reversing the motion of the fan.
Like letters are used to designate the same parts in the several views.
The fan-wheel A is made ofany suitable material, and is provided with fans or blades a, that may be formed by cutting the body ofthe fan radially and bending the blades to one side at any desired angle, as shown in Figs. 2 and 3; or the fan vheel may consist of a continuous disk having the blades or fans'secured to one side in any convenient manner. This fanwheel is provided with a shaft, B, to one end of which it is secured by any suitable means, so as to be detached therefrom when desired. The shaft B carries near its other end a pulley or grooved spindle, b, and is journaled in suitable loearings formed in the arms 0 c, which are secured to the upper end ofa standard, (J, that (No model.)
that the part may be readily detached when desired. In attaching this device to a sewingmachine, table, work-bench, or other place where the cooling etfeots produced by the revolution of the fan are desired, and where there is a convenient motive powersuch as a revolving wheel, E-it will be seen that the foot of the standard 0 will be clamped to the table or support F in convenient proximity to said wheel, from which a band, belt, or cord, 0, is passed to thcpulley b, thatisjournaled between the arms 0 c of the standard. The power imparted to the wheel E is thus transmitted to the pulley b, so as to cause the fan-wheel A to revolve with the shaft B, and thereby create a cooling current that will contribute greatly to the comfort ofa person working at the machine or table to which the device is attached.
When' the device is to be attached to a machine that is not provided with a convenient wheel or pulley for the attachment of the cord 6, I have found it useful to employ a wheel or pulley, Gr, having armsg, provided with springclamps 9, that may be made to clasp the inner edge of the rim of a spoke-Wheel, H, as shown in Fig. 4, the pulley G being thus caused to rotate with the wheel H, and thereby actuate the fan-wheel through the cord or belt connecting the pulley G with the pulleyon the fan-shaft.
If desired, the fan-wheel may be arranged to rotate in a direction opposite to that in which the motive. power is applied. This result may be effected by any convenient means-such as that illustrated in Fig. 5, in which the pulley b is secured to a short tubular shaft, B, that is journaled in the bearings c c, and carries on its end nearest the fan-wheel a bevel-gear, f. The shaft B, to which the fan-wheel A is secured, will then be provided with a bevel-gear, g, and be of such diameter or reduced at one end as will permit its being passed into the tubular shaftB. An arm,h, projecting from the standard U beneath the gears f and g, is provided with a stud, 2', upon the upper end of which is journaled a bevel-gear, 70, which is arranged in a horizontal position beneath the gears fand 9, so as to meshtherewith and thereby enable the shaft- B and attached fan to be rotated in a direction opposite to that in which the shaft; B is revolved. The stud i is passed through an opening in the arm h, where it is held by a set-screwmz. This set-screw may be removed, so as to allow the geark to be lowered, and thus become disengaged from the gear-sf and I, when the set-screws s .9, attached to the tubular shaft B. may be tightened. so as to clutch the shafts B and B and allow them'hoth to he rotated in the same direction, as ifone shaft only was used.
Having thus described myinvention, What claim as new, and desire to secure by Letters Patent, is-
The combination of the standard 0, having arms or bearings c c and arm h, the tubular shaft 13, journaled in the bearings 00 and having pulley b, bevel-gear f, and set-screws s s, the shaft 13-, adapted to enter the tubular shaft and provided with fan-Wheel A and bevel-gear g, and the adjustable stud 'i. having bevel-gear 70, all suhstantiall as and for the purpose described.
In testimony whereofI afiix my signature in presence of two witnesses.
ANSON HILGER.
