DINING-TABLE. FAN.

SPECIFICATION forming part of Letters Patent No. 398,250, dated February 19, 1889. Application filed Jul 13,1888. Serial No. 279,822 (No model.)

To all whom it may concern:

Be it known that 1, DAVID JAMES GREGORY, a citizen of the United States, residing at Scranton, in the county of Lackawanna and btatc of Pennsylvania, have invented certain new and useful Improvements in Dining Table Fans; and I do 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 ('[COOIII panying' drawings, and to the letters and tigurcs of reference marked thereon, which Form a part of this specification.

This im'ention relates to fly-fans for dining or other tables, and has for its object the provision of a fan that can be readily operated by the foot on atrcadlc within convenient reach, and which will be simple, compact, and efficient.

The improvement consists of the details of construction, which hereinafter will be more fully described and claimed, and shown in the annexed drawings, in which Figure 1 is a perspective view of a table, showing my invention applied thereto; and Fig. 2, a sectional detail about on the line X X of Fig. 1.

The table A is of ordinary construction, and is shown simply to illustrate the application of myinvention. The standard l3, having the tan-operating devices on its upper end, is socured to the table at its lower end, and is preferably tubular to form a case for the rod a. The block I) is secured to theplate 1), provided at the upper end of the stamlard, and has the uprights fastened to its sides. The shaft I) is journaled in the brackets (t on the block I), and its ends project through openings in the u nig'hts (I and have the fans E ad j ustal )ly mounted thereon. lever F, keyed on the shaft I), has its horizontal arm connected with the rod (1 The vertical arm of the bell-crank lever D is slotted, and the cross-barf, that closes the outer end of the slot, is rounded. The shaft G is journaled in the ln'ackets g, secured to the uprights (1, and its ends are provided with fans E. This shaft is operated from the shat't D by any suitable interposed connections or The b ell-crank gearing, that shown being the arm I, which engages with the vertical arm of the bellcrank lever. This arm I is secured to the shaft G, and its lower end is bifurcated and embraces the end f of the lever F. The shaft 5 5 G is provided intermediate of its ends with the second fan E which is double, being socured to the shaft by the set-screw 0', which passes through the arm I.

The fans E and -E' are constructed. alike, and are formed from sheet material, which is cut to form the wings e e and the stem 6, the blank being sul)s quently bent to have the wings stand at an angle of about forty degrees and the stem 6 to form a tube which embraces the end of the shaft. The thumbscrcw 6 holds the fan adj ustably on the shaft. The rod a passes down through the table, and is connected to the treadle J which is supported on the stand K, connected with the table by the brackets j. The inner or lower end of the treadle is provided with the plate L, which is bent to bring its ends in different planes, and is provided with pairs of brackets l and Z, which are disposed on opposite sides of the plate. The rod a is pivotally connected with the brackets Z, and the treadle J is pivotally connected with the brackets Z. The coii-sprin M, mounted on the rod a and confined between the table and the plate I 1t orccs the inner end of the treadlc down.

To operate the tans, th e person presses down on the trcadle,which effects an upward movement oi": the inner en d of the treadle and the rod a. Thepressure beingremoved, the spring carries the treadle back to its normal position. This movement causes a "ibratoryinotion of thebell-crank lever and a corresponding motion of the fans, which drives off the flies. go

It will be noticed that the plate L is pivotally connected with the end of the treadle J, to facilitate the operation of the latter beyond what could be obtained if the said treadle were rigid from its outer end to the point of connection bet-ween. the said lever and the rod (1, as will be readily con'i -irehemled.

Ilaving thus described my invention, what I claim, and desire to secure by Letters Patent,
