TREADLE.
SPECIFICATION forming part of Letters Patent No. 558,716, dated April 21, 1896. Application filed November 30,1895. erial No. 570,582. (No model.)
To all whom it may concern:
Be it known that 1, JAMES E. BRADLEY, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Machine-Treadles; and I do hereby 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 accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.
The object of this invention is to enable the floors of factories, having large numbers of sewing or other machines operated by power and governed or controlled by foot-treadles fastened to the said floors, to be swept after work hours with greater facility and more thoroughly than has been possible heretofore; and the invention consists in the improved machine-treadle, and in the arrangements and combinations of parts, all substantially as will he hereinafter set forth and finally embraced in the clauses of the claim.
Referring to the accompanying drawings, in which like letters indicate corresponding parts in each of the views, Figure 1 is a plan of the improved treadle and its bearings, the connection with the machine being shown in section. Fig. 2 is a side view of one of the bearings; and Fig. 3 is a front elevation showing the treadle in normal operative position, and in outline raised to admit of an easy and convenient sweeping of the floor.
In said drawings, a a are bearings adapted to be fastened to the floor by screws 1) or other means.
0 is the foot-plate on which the feet of the operator rest when operating or controlling the operations of the machine, and d is the shaft carrying said plate, and adapted to be oscillated in its bearings thereby when said plate is turned by pressure alternately at the forward and rear sides by the feet of the operator in the ordinary manner.
The bearing a is provided with a notched upright a, in the notch of which the shaft (1 rests when in its horizontal position. It is held, in the preferred construction, in said notch by a catch c, Figs. 1 and Said catch is preferably in the form of a lever f ulcrumed at e and controlled bya springf. Said spring serves to throw, the catch automatically into engagement with the end of the shaft when the latter is forced down to its horizontal position. By pressing the foot upon the horizontal end of the lever-like catch, the hooked end thereof is thrown away from the end of the shaft d and the latter may be raised, or, in the preferred construction, automatically rises, under the power of the tilting-springs g, to the vertical position shown in Fig. 8. The shaft oscillates in said notch and is beveled, as in Fig. 3, so as to throw the hooked end of the catch outward and pass automatically down to its bearin g in the notch, as will be apparent.
The foot-plate is adjustable in its relation to the shaft (Z both longitudinally on said shaft and in its degree of inclination to the floor, set-screws 7t 72, serving to hold the parts at the desired adjustment. The bearing a for the opposite end of the horizontal oscillatin g shaft (Z comprises a fixture 2', attachable to the floor, having vertical ears jj, between which a T-shaped bearing-piece 7t is pivoted, as shown in Fig. 1. The arm Z of said lbearing-piece is hollow and receives the extremity of the shaft (Z, and serves to allow the desired oscillatory movement. The T-shaped hearing also serves as the hinge 011 which the said shaft and its foot-plate may be turned to and from the desired position to allow of an easy and free sweeping of the floor beneath where the said foot-plate normally rests.
The spring 9 is preferably coiled around the T-shaped hinge'piece and has an arm extending a little distance along the shaft, bearing upward on the under side, so as to raise said shaft automatically when the latter is released. Adjacent or contiguous to said hingepiece at one end of the shaft (1 is fastened an arm m, which projects forward. or to one side of the shaft to provide an eccentric bearing for the connecting-rod n, which extends upward to the machine, to govern or control the clutching or other operative mechanisms of the machine or to otherwise effect the operations of the same. Said connecting-rod is pivotally coupled to a lateral extension m of said arm on at a point in line with the center of oscillation of the hinge member 7c, 011 which the shaft cl tilts in rising to its vertical position and thus the action of said shaft when raised on its end will not affect any operation of said conn ectin g-rod n or produce a disarrangement of the working parts of the machine.
The oscillation of the shaft d in its bearings a (0 produces a corresponding reciprocating movement of the arm on and connecting-rod n in the usual manner, as will be understood without further explanation.
I have provided the bearing a with a catch for holding the foot-plate and its shaft in its elevated position while the floor is being swept. This may be of any suitable construction; but the construction preferred is illustrated in the drawings and consists of a sliding latch 0, having bearings in the earsj jof the fixture i. Said latch at one end is provided with a beveled nose 1) and at the opposite end with a return-bend o, the extremity of which enters a second bearing in one of the ears j, and thus said latch will be prevented from turning pivotally in its bearings, and the beveled nose will maintain a proper relation to the hinge. A spring q tends to hold the nose 1) in its normally-projecting position outside the ear j, and a foot-lever 0, having a fork s, engaging a shoulder 75 of the latch, is adapted to repress the latch against the power of the spring when the foot is pressed upon the horizontal pedal to to withdraw said latch from its treadle-holding position. A stop projection 41 limits the upward movement of the treadle, stopping it when at the vertical position of Fig. 3 just after the hinge-finger w has passed over the nose of the latch and the latter has sprung into its normal holding position.
The finger w referred to is fastened upon the hinge-piece 7t outside of the earj, having a bearing for the beveled or nose end of the latch, and turns with said hinge-piece, so as to engage the stop and nose entering between the same, as indicated in Fig. 3 in outline.
In operating the device, when it is found necessary or desirable to sweep the floor the janitor simply places his foot upon the horizontal foot portion or pedal of the lever c and thus releases the free end of the shaft. The spring 6, when one is employed, then acts automatically to raise said shaft on its end, and with it the treadle foot-plate c. This enables the fioor to be swept thoroughly and quickly, and while this operation is being carried on, said treadle is prevented from being thrown down accidentally, by the latch, which has automatically caught the fingers w, as'described. After the floor has been swept the latch is drawn back by pressure of the foot upon the pedal u, and the treadle is thus released and may then be pressed down by hand or otherwise, so that the said free end will enter the notch of the bearing a and be automatically caught and held therein by the catch e.
IVhile I have described the preferred construction of the device in detail, I am fully aware that various modifications may be made and parts omitted without materially altering the invention, broadly considered, and therefore I do not wish to be understood as limiting myself by the specific descriptive terms employed, e-xceptin g as the state of the art may require.
