FAN ATTACHMENT FOR SEWING-MACHINES.
SPECIFICATION forming part of Letters Patent No. 445,843, dated February 3, 1891. Appiaaion filed my 23,1890. serai No. 359,619. (No model.)
.To all whom it may concern.'
Be it known that I, LEOPOLD BERCHER, a resident of Fort Smith, Sebastian county, Arkansas, have invented certain new and useful Improvements in Fan Attachments for Sewingddachines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.
' My invention has for its object to provide a useful and ornamental construction in a fan attachment for sewing-machines; and it consists in the novel combination and arrangement of parts, as will be hereinafter fully described,` and designated in the claims.
In the drawings, Figure lis a vertical longitudinal section of my complete invention as applied to a sewing-machine. Fig. 2 is a top plan view of the adjustable collar to which the fans are attached. Fig. 3 is a front elevation of the disk used for attaching the device to the sewing-machine. Fig. et is a perspective view of one of the fans detached. Figs. 5 and G are detail views, and Fig. 7 is a side elevation, of myinvention, showing its application to a sewing-machine.
Referring to the drawings, l represents the ordinaryfly-wheel of a sewing-machine to which my invention is applied, and 2 the stand or table for the said sewing-machine and to which is attached the support or base of the device.
3 represents the base of the device, having a flaring bottom et, through which portion holes are formed to receive two turn-bolts 5 5, said bolts passing also through holes formed'in the stand 2, the screw portions of which are screwed into washers 6, by means of which the said base is securely fastened to the stand. The upper portion of the base 3 is provided with a vertical cavity 7 ,within which the vertical shaft 8 revolves and is supported thereby. The vertical shaft 8 is provided with an annular groove 9 near the lowerportion thereof, and is covered by the walls of the cavity 7 when the said shaft is in its properposition. A screw-threaded hole is formed in the upper portion of the base 3 for receivinga turn-bolt 10, the end of which enters the annular groove 9 and prevents the vertical shaft 8 from being withdrawn when in a working position, as best shown in Fig. 1.
11 represents a circular disk, the face of which is provided with a number of openings 12, and having arms 13 formed therewith and extending rearward thereof,and which support a comparatively large bevel cog-wheel 14, by means of which the shaft 8 and its parts are revolved. 15 are inserted in the openings 12, the lends of which are screwed into clamps 16, by which means the circular disk 11 is firmly clamped upon the annular rim 17 of the fly-wheel.
The double row of openings formed in the face of the disk 11 is for the purpose of adjustment, and by which means the same can be clamped to fly-wheels of diiferent sizes.
Encircling the vertical shaft S is a collar 18, and to the said collar is fastened a lug 20, upon which the large bevel gear-wheel 14 revolves, and which is prevented from moving` od the same by the nut 21. A small bevel cog-Wheel 22 also encircles the vertical shaft S, the upper portion of which is provided with a collar 23,and through said collar is screwed a turn-bolt 24, the end of which bears against the vertical shaft Sand serves to hold the said small bevel-gear in a working position with the large bevel gear-wheel lat and meshing therewith.
25 represents an adjustable collar located "upon the upper endvof the vertical shaft 8, encircling the same, and made adjustable thereon by means of a turn-bolt 26. The adj ustable collar 25 is provided with four vertical slots 26 of V-shaped construction, the sides of which verge or nearly meet at the outersurface of the said collar and which serves to hold four removable fans 27 when inserted therein. The fans, as shown, are provided with a rounded edge 2S about one-halt their width, said rounded edge being formed by bending the metal around any suitable former, while the lower or remaining portion of the fans is bent flat upon itself, allowing the said portion to be freely insert-ed in the vertical slots 26 of the adjustable collar 25, the rounded portion of the fans resting upon the upper edge of the said adjustable collar.
If found convenient, the large bevel gear- A series of thumb-bolts IOO wheel may be cast with the fly-wheel of the sewing-machine, Vand the small bevel gearwheel mesh with the same in the before-described manner, thereby dispensing with the disk and its parts.
In operation, to attach the device to a sewing-machine, the base 3 is located upon the stand of the machine in proximity to 'the ilywheel, and then the clamps 16 are located on the opposite side the''ly-wheel or thearms or spokes thereof, and the thumb screws or bolts l are inserted in the openings 12 and their ends screwed into said clamps, care being eX- ercised during this operation that the center of the disk 1]. is located in alignment with the center of said y-wheel. Then by means of thumb screw or bolt 24 the small gearwheel or pinion 22 is loosened'upon the'shaft and lowered into position to engage the large wheel ll-,where it is to be secured by the same means, as is understood. rlhe fan-holding collar 25 is next to be properly adj usted in position upon the' shaft, so as to direct the current of air upon the operators face, which may be done by manipulating the screw or bolt 26. The devices now being in proper position, as stated, the wingsof the fau will be given a comparatively high speed during the ordinary operation of the machine, creating a blast or current of air, as will be understood.
It will be seen that the wings of the fan mayA be removed when desired and others supplied by simply sliding them upward in their fastenings as far as necessary.
`That I claim is- 1. The combination, with a vertical revolving shaft, of a collar carried by the said shaft and having V-shaped slots upon its periphery, and fan-blades having the lower portion of each of their inner edges bent. flat upon itself and contained within the slots inthe said collar, the upper portion of each of such edges being rolled back upon itself` and rounded, as described.
2. In a fan, the combination, with a sewing-machine having a flanged fly-wheel thereon, of a base having a vertical cavity therein, a shaft stepped in the said base, a disk having perfora'tions in concentric rows therein,
bolts passing through perforations of one of the said rows and Within the periphery of the fly-wheehclamps upon the said bolts bearing againstthe `flange of the said ily-Wheel, a pinion carried by the said perforated disk, agearwheel upon the said shaft engaging the said pinion, and fans carried by the said shaft, as described.
3. In a fan,the combination, with a'sewingmachine having a flanged ily-wheel thereon, of a base having a vertical cavity therein, a shaft stepped in the said base, a disk having perforations in concentric rows therein, bolts passing through perforations of one of the said rows and within the periphery of the iiywheel, clamps upon the said bolts bearing against the flange of the said [1y-wheel, a pinion carried by the said perforated disk, a gearA Wheel upon the said shaft engaging the said pinion, a collar upon the said shaft having a lug thereon passing through the said pinion, and fans carried by the said shaft, as de scribed. y
In testimony whereof I affix my signature in
