UNITED STATES PATENT OFFICE.
FRANK G. JUNEY, OF ROCHESTER, NEIV YORK.
PLUMB-LEVEL.
SPECIFICATION forming part of Letters Patent N 0. 569,500, dated October 13, 1896.
Application filed February 26, 1896. Serial No. 580,792. (No model.)
To all whom it may concern:
Be it known that 1, FRANK G. J UNEY, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Plumbs; 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.
My invention has relation to improvements in plumbs, the implement used by artisans for erecting perpendiculars or to ascertain the deviation of an object from a vertical line; and the object is to provide an implement of the kind named and for the purpose stated which is of simple construction, accurate in its uses, and efficient in determining the correctness of a vertical line or surface and indicating any deviation therefrom.
I have fully and clearly illustrated my improvements in the accompanying drawings, forming a part of this specification, wherein Figure 1 is a front view in elevation, showing the implement with the front plate removed. Fig. 2 is a central vertical section. Fig. 3 is a detail perspective of one of the clamping or holding springs With the rubber button inserted therein. Fig. 4 is a detail of the plumb needle and weight.
The implement may be made of any suitable material and consists of a removable back plate, an intermediate plate suitably chambered or recessed to take and support the plumb weight, rod, or needle, and a front plate adapted to fit over the face of the intermediate plate and which is a counterpart of the rear plate, or the implement may consist of two plates, one of which is chambered or recessed to take the plumb weight or rod.
Referring to the drawings, A designates what may be termed the rear plate, consisting of a rectangular piece of suitable material having plane parallel sides, as is usual in the construction of implements of this character, and formed adjacent to its upper end with an aperture 1, in which is fitted and secured a sight-glass 2. To the inner face of the plate A is secured the plate B, accurately alining in all its sides to the plate A and formed with a chamber or recess 4, extending longitudinally of the implement and reaching above the aperture to the top of the aperture in which the sight-glass is secured, substantially as shown in Fig. 1 of the drawings. Reference being thereto had, it will be perceived that the chamber or recess is narrowed at the pivotal point of the weight, as at 5, and flaring therefrom to the top, as at 6. Below the pivotal point the chamber is widened to receive the weight. This conformation or construction of the chamber afiords room for the vibration of the weight and the plumbrod. In the opposite faces of the plate B, at the top of the recess and in accurate alinement with each other, are secured graduated scales 3, the center or middle lines of which are in alinement with and vertical to the pivotal axis of the plumb-rod. To the face of the plate B is secured the plate 0, its contour or sides being the same as that of the other plates, and it is formed with an aperture 1 registering with the aperture 1 in the plate A, and provided with a sight-glass 2 through which the scale is observable. In the chamber or recess of the intermediate plate, on a suitably-secured pivot 7, is hung the plumbweight 8, the axis of its pivotal support being in a direct vertical line with the central graduation on the scales and the two points in direct alinement with the sides of the implement, and in the upper end of the weight is fixed a pointer or needle 8 the upper end of which traverses the scales and indicates the position of the vertical surface against which the implement may be placed. In the sides of the chamber or recess are fastened rubber cushions 9 9 ,against which the weight impacts if vibrated violently, the cushions serving as buffers to obviate the efiects of the concussion of the weight against the frame when the implement is being carried or when it may be handled carelessly. In the plates A and O are formed oppositely-arranged recesses 1O 10 on the inner faces of the plates, and centrally through each recess is an aperture 11. The recesses constitute seats for springs 12 15?, secured therein, substantially as shown, and in the springs are secured elastic buttons 13 13 projecting through the aperture in the plate, and the inner ends of which are adapted to be pushed against the opposite faces of the weight, so that an equal pressure may be made to hold the weight steady and the pointer free from vibration or disturbance while approaching the object to be tested and so that when the pressure is removed the Weight will bring the pointer to position on scale at once.
The implement is adapted for placing or setting columns of any description to a perpendicular position. Should the column be tapering, the needle or pointer registers the variation on the scale-plates, the scales being graduated to indicate the variation from the vertical line by the foot.
The implement is generally useful in erecting any and all work the perpendicularity of which is to be ascertained.
Having thus described my invention, what I claim, and-desire to secure by Letters Patent, is
Y A plumbing implement, comprising astock in the chamber of the stock, a pointer on the upper end of the weight above the pivotal support thereof, oppositely-disposed springs seated in the chamber of the stock, and elastic push-buttons projected through the sides of the stock and secured in the arches of the springs whereby the weight may be clamped between the inner ends of the push-buttons, substantially as and forthepurpose specified. In testimony whereof I hereunto affix my signature in presence of two witnesses.
