Knxxnm' and Euro W. CARLSON, citizens of the United States, residing at Schenectady, in the county of Schenectady and State of New York, have invented a new and useful Inclinomehar, of which the following is a specification. 7
Our invention relates to improvements in inclinomcters, and has for its object the provision of a device by which the angle of inclination ofany surfacemay be quickly noted and which will be of very simple construction so as to operate easily and accurately.
The invention seeks to provide a device for the stated purpose which will be composed of very few parts so that it'may be readily assembled, and the frictional resistance oifercd the moving parts will be reduced to a mininnuu.
A device embodying our invention is-illustrated in the accon'ipanying drawings, and
the invention consists in certain novel features of construction and arrangement which will be hereinafter first fully described and then more particularly pointed out in the claims.
1n the drawings,-I igure 1 is an clevation of our improved device showing it in its operative position. Fig. 2 1s a trans .verse section taken through the of the a straight edge 2 on its lower side and is,
preferably constructed with a lognitudinal groove 3 in said edge'in order that it may be readily used upon a curved surface with out tilting.- The frame or body 1 is provided with a central circular portion, indicated at 4t, and this central'circular portion is hollowed so as to provide a chamber 5 in which the pendulum or weight 6 may oscillate. The front side of the body is rabbeted, as indicated at 7, to provide a seat for the stationary disk 8 constituting a cover for the chamber 5 to prevent the access of dirt or other deleterious matter which would tend to clog or interfere with the operation of the pendulum. The disk 8 is provided with a central opening 9, and the back of the body is provided with a smaller opening, indicated at 10, to register with the said opening 9 andconstitute a bearing in which the end of the pivot and securing screw 11 is mounted. The pendulum or weight 6 may be of any suitable size or shape and its lower edge 12 is curved so as to lie concentric with the side of the chamber 5 when the parts are assembled, while at the upper end of the pendulnin or weight we provide a transverse threaded opening 13 through which the pivot or securing screw 11 is inserted. The weight is further provided on its front side at its upper end with an annular projection 14 which is adapted to engage the central opening $1 in the disk 8 so as to journal therein. The inner end of the screw or pivot 11 is smooth, as shown at 15, so as to'engage the opening in the back wall of the body and rotate freely therein, while an intermediate portion of the pivot is threaded, as shown at 16, to engage the threaded bore 13 of the pendulum and thereby secure the pendulum firmly in place. The pivot is provided with a milled head 17 and an annular off-set or shoulder 18 at the inner side of the said-head, and also has a smooth portion 19 adjacent the said shoulder 18, as shown most clearly in Fig. 5. A dial or indicating. disk 20 is fitted upon the smooth portion 19 of the pivot and is clamped against the shoulder 18 by the turning of the pivot so that the pendulum will be caused to move toward the shoulder 18 by reason of its threaded engagement with the pivot and, consequently, bringthe proje'd tion 145 firmly against the inner face of the dial 20, as clearly shown in Fig. 2, and as will be readily understood. The dial 20 is provided with a zero mark which is located ota point corresponding to the middle of the lower edge of the pendulum, and on the face of the dial around the upper-half of the edge thereof we provide a series of graduations 21. which extend in both directions from a central graduation 22 marked zero. A fixed zero point 23 is also 'providcd on the body above the dial at the vertical center of the same which, when the device is on a horizontal surface, will register with the zero mark 22 of the graduations on the dial. A series of graduations Cit 24, corresponding to the graduations 21 on the dial, is marked around the lower half of the opening in the body, and the central graduation 25 is marked zero and adapted to register with the zero mark 26 on the dial previously mentioned.
In assembling the parts, the pivot is inserted through the central opening in the dial 20 and through the central opening 9 in the disk 8 and then engaged in the threaded bore 13 of the pendulum and rotated so that by reason of its engagement with the pendulum, the dial 20 will be clamped'firmly between the shoulder 18 and the frontface 1 of the projection 14 on the pendulum. The
several parts thus assembled are then made to register with the chambered portion of the body 1 and the end'of the pivot engaged in the opening 10 in the back wall of the body, thereby bringing the edge of the disk 8 into the recess presented by the rabbet 7, as shown in Fig. 2. The disk 8 is then secured to its seat by solder or other convenient means and the device is ready for use. When 1t 18 deslred to ascertain whether a machine or other object is in a horizontal position, the body 1 is placed upon the surface of the machine or other device and will, of course, assume a horizontal or inclined position, the same as that of the surface upon which it is placed. The pendulum or weight 6 will always remain in a vertical position, and the dial will necessarily follow the movement of the pendulum. Should the surface against which the body is placed not be horizontal, the several zero marks will be carried out of alinement and the angle of inclination will be readily'noted by means of the scales or graduations on the dial and the body. In the example shown, the zero mark on the dial is in alinement with the graduation marked on the body and, consequently, the device is at an angle of thirty degrees to the horizontal. The same reading is given by the zero mark on they body compared with the scale on the dial, and this will be found very advantageous as it enables the operator to make the proper reading, even though the surface upon which the device is placed may. be below some projections or bearings which would partly hide the dial.
Our device is obviously very simple in its and, consequently, give accurate readings.
Having thus described our invention, what we claim is j 1. A device for the purposeset forth comprisinga body having a central circular chamber, a disksecured to the body to cover the said chamber, a dial arranged in front of the said disk, a pendulum arranged with- 6 in the chamber of the body and having a projectionat its upper end journaled in the.
' said. disk, and a pivot having a smooth innor end journaled in the rear Wall of the body, a shoulder atits front end, a smooth portion adjacent the said shoulder, and a threaded portion intermediate said smooth portion and its smooth inner end, said threaded portion of the pivot engaging a threaded bore in the upper end of the ,pen-
dulum whereby the dial will be clamped between the pendulum and the inner shoulder of the pivot.
2. A device for the purpose set forth comprising a body having a substantially circular chamber; a stationary disk secured to the body to cover the said chamber, a loose dial arranged in front of said disk, a pendulu-m arranged within the chamber of the body, means for connecting the pendulum to the dial to ,cause'them to move in unison, said means constituting the pivot of the said parts, a series of graduations of. 180degrees marked upon the top half of the dial, and a series of'graduations of 180 degrees marked upon the lower half of the chamber of the body.
In testimony that we claim the foregoing as our own, we have hereto aflixed our signatures in the presence of two witnesses. 9
