PIVOT.
SPECIFICATION forming part of Letters Patent No. 786,509, dated April 4, 1905. Application filed July 9,1904. Serial No. 215,862.
To all whom it may concern.-
Beit known that I, GORDON MERRITT, a citi- Zen of the United States, residing in Ridgewood, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Pivots, of which the following is a specification.
This invention relates to and has for an object to provide an improved pivot for levers.
In the drawings accompanying and forming part of this specification, Figure 1 illustrates in side view an embodiment of my present improvements. The lever or bar which is pivoted is shown as broken away, suflicient, however, of the bar being presented to illustrate the surrounding features. Fig. 2 is a plan view of the device shown in Fig. 1, and Fig. 3 is a cross-section thereof upon the axial line of the pivot.
Similar characters of reference designate like parts in the various figures.
One feature sought to be accomplished in the present improvements is to afford a leverpivot which may be readily adjusted to permit the lever to be removed from its support and also to afford lateral adjustment as well as to take up play in the pivot-bearings, and also one to permit the longitudinal adjustment of the lever relative to its bearing.
This invention is useful in various structures wherein a lever is to be pivoted and in which ready adjustment of the pivots is desirable as well as the removability of the lever, and one such use is in connection with pianopedals.
The lever (designated in a general way by 7) is illustrated as broken away at its ends and may be attached to any suitable elements for performing any function which may be desired and in which this form of pivot is required. The lever is shown as made of sheet metal and has a bottom portion 8, which is represented as being substantially fiat, and a top bearing portion 9 to act as a seat for some clamping or securing device.
For the purposes of the present description the device is shown mounted upona base or bed plate 10, having a pair of standards 11, each of which standards has a socket 12, in which sockets bearing-blocks 13 are mounted,
which bearing-blocks in the present instance are shown as having conoidal bearing-surfaces l t and as having shoulders which may be in the form of a flange 15 to prevent the bearings from being displaced in the sockets. Although these bearings are shown as carried by separate blocks, yet in practice in some instances it maybe found desirable to put the bearings for the pivots directly upon the machine or part instead of employing the separate bearing-blocks.
The lever is shown supported by pivots .18, carried by a carrier designated in a general way by 16, and which in the present instance is in the form of a yoke, having at its bottom portion substantially straight or flat members 17, being practically parallel with the face or portion 8 of the lever. The pivots in the present instance each has a conoidal bearingpoint 180, which in practice may be more acute than the bearings .14, and each of which pivots in the present instance has a shank portion 19, carrying screw-threads and pass ing through screw-threaded openings 20 in the sides of the yoke. The pivot-shanks when in position will be exposed in part to the lever and in the illustration lie between the portions 1'7 of the yoke and the portion 8 of the lever, and by means of some clamping device the carrier and lever may bind the pivots in their positions of adjustment. In the present illustration the clamping device bears upon the face 9 and reacts upon the portion 21 of the yoke. The shanks of the pivots will be securely held in place between the lever and the yoke, so that after their adjustment the clamping of the lever in place will clamp the pivots in place also. In the present instance a set-screw 22 enters a screwthreaded opening 23 in the portion 21 of the yoke and will press the lever upon the shanks of the pivots. It will be noticed in the illustration that the screw-threads upon the shanks are sunk into the lever and the yoke, thereby accelerating the clamping action. To afford a certain amount of yieldability, the yoke may have adjacent to the pivots an opening 24:. The yoke having such formation may yield when pressure is applied to the seti screw and put an amount of tension on the pivots. The pivots are shown as having squared or nut-formed ends 25 to receive a wrench for effecting their adjustment. Other than screw-threaded shanks may be carried by the pivots; but the screw-threads will permit adjustment more readily in some instances than plain shanks and also afford a stronger lock when the lever is clamped in position.
From the foregoing description it will be evident that the lever after having been adjusted longitudinally may be adjusted laterally by means of the adjustment of the pivots and then the whole device secured in an adjusted position by means of a single clamping element, in the present illustration a setscrew. It will also be observed that the bearing-blocks 13 may be made free in their sockets and held in place by means of the pivots and that such pivots are adjustable and project outwardly from the sides of the lever to engage the bearing-blocks.
I do not limit myself to the exact details of construction herein illustrated, since changes in construction may be made within the scope of my invention.
