unirse STATES PATENT oi-"Flciezg SAMUEL BOLOZKY, OF WEST NEW YORK, NEW' JERSEY, AD SAMUEL PEARL, 0F l f BROOKLYN, NEW YORK.
Application filed March 18, 1826, Serial No. 95,674.
Our present invention has to do 'with fans suoli as used in tailors shops and other shops; and it contemplates the provision of a peculiar and advantageous tan installation constructed with a view to permitting ot' the tan beingv readily put into and out of use, and also constructed so that the fan can be expeditiously and easily positioned for use to the best advantage.
Other objects and practical advantages Of the invention will be :t'ully understood from the following description and claims when tie same are read in connection with the drawings, accompanying and forming part of this specification, in which i Figure 1 is a` view, part-ly in elevation and partly in section, illustrating our improvement complete.
Figure 2 is an enlarged fragmentary section showing one oi' the joints of our improvements. i
igure 3 is an enlarged elevation taken from a view point at the right of Figure 1 and showing` `the means whereby the drive pulley of our improvement may be put into and out of engagement with a belt.
Figure l is a horizontal larged scale, taken in the plane indicated by the line Ll`1 or Figure 1, looking downwardly.
Similar numerals of reference designate correspondingl parts in all oi the views of the drawings.
Vle show at 1 in Figure 1 a table, and in accordance with our invention a plate 2 is fixed at 3 to the said table and extends'beyondthe edge of .the table top, ythe said extended portion oit the plate 2 being provided at l with a circular aperture and at 5 with a slot one wall of which is toothed as designated by 6.
A rigid upright tube 7 is arranged in the aperture 4 of the plate 2 and is appropriately connected to the said plate 2 so as to be supported thereby. We would have it understood in this connection that when deemed expedient frictionil contact between the tube 7 and the plate 2 may be depended upon for the support oi the tube 7 by the plate 2, the said relative arrangement of the tube 7 and the plate 2 ybeingadvantageous inasmuch as it is calculated to permit of endwise adjustment ot the tube 7. As before indicated, however, it is within the section on an enn our invention to connect the tube I to the plate 2 in any manner consonant, with the purpose of our invention.
y At 8 in Figure l, we show will be understood that `the liexible shalt 9 of our improvement is equipped at one end with a pulley l designed to be placed in engagement with one stretch of the said belt 8 rand also adapted to be moved out of engagement with said belt. The flexible shaft 7 and is rotatable axis in the manner common to flexible shafts. The lower portion or" the liexible shaft 9 is carried through a curvilinear tube section ll, the upper end of which is bifureated and is provided with arms 12 and 13, the said arms 12 and 13 being pivotally connected at 14 to the lower portion of the tube .7, and the arm 13 being merged intoa hand lever 15 which extends through and is movable in the slot of the plate 2, and isadapted to be placed remov-A ably in `nterdental SpacesV o1 the toothed portion 6 of the plate 2 with a view to justably positioningthe tube section 1l,k A suitable housing section 16 of lexible character is secured at its ends in the tube section `ll and in the, ltube 7 and receives the flexible Shaft 9 andl is adapted to lend itself to movements of the rtube section 11, Mani? festly through the medium of the hand lever and theconstruotion associated with the Said hand lever 15, the pulley l() may he purview of placed against or removed from the stretch' of the belt 8, and by .engagement ot the lever l5` .with the toothed portion Got the plate 2, the pulley 10 maybe detachably se-` cured ineither of said positions.
The upper portion of the tube .7 ,is prei!-v erably, though not necessarily, .equipped with a `thread holder'of appropriate type, designated by 17.
Extending' from the tube 7 is a tube seca belt, and it;
tion 18 disposed laterally to the tube section 7, and extending from the said tube section 18 is another tube section 19 of curvilinear .form by which is carried a fan guard 20X. This fan guard 2OX per se may be of any construction compatible with the purpose of our invention, and we, therefore, do not deem it necessary tb enter into a detailed description of the same. The flexible shaft 9 extends through the tube sections 18 and 19 and is equipped at its forward end with a fan 21 of appropriate type adapted to be freely turned in the guard 20X. The tube section 19 is fixed to a tubular member 20, Figure 2, and the said tubular member 20 is arranged in and adapted to be turned about its axis in the tube section 18. It will also be noted that the tubular member 2O is provided with a circumferential groove 21 which receives the inner end of a screw 22 threaded in the wall of the tube section 18. Manifestly when the screw 22 is loosened, the tubular member 20 may be turned about its axis in the tube section 18 for the proper positioning of the tube section 19 and the fan guard and fan, and after the said parts are adjusted as desired, the tube section 19 may be adjustably fixed with respect to the tube section 18 by tightening of the screw 22. The adjacent portions of the tube and the tube section 18 are connected together at 30 in the same manner that the tube section 19 is connected to the tube section 18. Consequently it will be understood that the tube section 18 may be swung laterally and adjustably fixed on the tube section or tube Y so as to contribute to the desired positioning of the fan 21 and its guard 20,
It Will be apparent from the foregoing that notwithstanding the advantages ascribed to our novel installation, the installation is simple and inexpensive in construction, is well adapted to withstand the usage to which installations of corresponding character are ordinarily subjected, and is adapt ed to enable a workman to position the overhanging or overhead fan to the best .advantage according to the conditions to be met.
We have entered into a detailed descrip-A tion of the best practical embodiment of our invention of whichV we are cognizant in order to impart a full, clear and exact understanding of the said embodiment. Ve
do not desire, however, to be understood as f limiting ourselves to the precise construction and arrangement of elements as disclosed, our invention being defined by our appended claims Within the scope of which modifications in structure and in arrangemet may b e made without departure from 2* our invention.
Having described our invention, what we claim and desire to secure by Letters Patent, is
1. In combination, a rotary driving element, an appropriately supportedswingable tube, a tube section having a bifurcated portion the arms of which are disposed at opposite sides of and are pivotally connected to the first-nained tube, and also having one of said arms merged into a hand lever, said lever of fiexible or resilient character, a flexible shaft extending through .and rotatable in the tube and said section, a pulley on .said shaft and adapted to be moved by movement of the swingable tube sections into and out of engagement with the rotary driving element, and an appropriately supported element having a rack for cooperation with said resilient lever,
2. In combination, a rotary driving element, an appropriately supported tube, a swingable tube section having a bifurcated portion the arms of which are disposed at opposite sides of .and are pivotally connected to the first-named tube, and also having one of said arms merged into a hand lever, said lever of resilient character, a flexible shaft extending through and rotatable in the tube and said section, a pulley on said shaft and adapted to be moved by movement of the swingable tube section into and out of engagement with the rotary driving element, and an appropriately supported element having a rack for cooperation with said resilient lever; the opening formed by the bifurcation of the tubular section being bridged by a flexible housing containing the flexible shaft and secured in the adjacent portions of the tube and tubular section.
8. In combination, a rotary driving element, a flexible shaft, an element on said shaft and adapted to be put into and out of engagement with said rotary driving element, a tube through which the flexible shaft extends, a swingable tubular section also receiving the fiexible shaft and pivotally connected to said tube, an appropriately supported rack, and a lever fixed with respect to the tubular section and adjustable relative to said rack for the adjustable fixing of the element on the flexible shaft in engagement with the rotary driving .element and out of engagement with respect to the same.
In testimony whereof we affix our signatures.
