Specification of Letters Patent.

Patented 31, 1921.

Application filed October 22, 1918. Serial No. 259,198.

To all whom it may concern:

' Be it known that 1, Amino EnLn SUMnnsiLLn, citizen of the United States, residing at San Juan, in Porto Rico, have invented new and useful Improvements in Dividers, of which the following is a specification.

The invention has for its principal object to provide a device of the above-mentioned character, the construction of which is novel in form and permits of the use of the device as a pair of scissors or as a pair of dividers or calipers.

More particularly the present invention consists in the provision of a device of the above -mentioned character wherein mproved means is employed in conjunction with the means for pivoting the sections together for arranging the sections to vary the distance between the pointed ends thereof, while cooperating with the form is an additional clamping means for removably maintainingthe sections in a. substantial po sition relative to each other.

It is a more specific object of this invention to provide a device of the above-mentioned character wherein the blades are graduated so that the material being cut may be measured at the time of being out.

Other improvements and novel details 1n the construction and arrangement of the various parts of the apparatus will be brought out more in detail in the description to follow, which for a clear understanding of the invention should be considered in connection with the accompanying drawings forming a part hereof, and wherein is disclosed for the purpose of illustration a convenient and satisfactory embodiment of the invention. It is to be noted in this connection that minor changes in the construction and arrangement of parts may be made without departing from the principle of operation of the various parts. The invention is clearly illustrated in the accompanying drawings, in which:

Figure 1 is a top plan view of the device showing the parts in an open position;

Fig. 2 is a similar view showing the parts in a closed position; and

Fig. 3 is a cross-section taken on line 3-3 of Fig. 1. 7

Referring now more particularly to the accompanying drawings, there is provlded a pair of complemental sections 1 and 2 each of which consists of a body portion tapered toward one end to a point a and sharpened on one edge to provide a blade. Both blades are graduated as at 7 and 8, the graduations on the two le..ding in opposite directions. Handles 9 are formed on the opposite end or. the body portions and the body portions are formed with enlargements 10 each of which constitutes hammer head if it is desired to use the device as such. The body portions of each section are formed with a central opening; while rigidly fitted in the opening in the section 1 is a pivot bolt 11, and this bolt also passes through an eyelet 12 which. is in turn positioned within the opening in the section 2. The further medial portion of the bolt is squared as at 13, while the outer portion is round in crosssection and is threaded as at 1 1. Fitted about the reduced squared portion 13 of the bolt is a disk 15 which is provided with graduations 16 near its outer edge, and this disk is held against the shoulder formed at the junction of the squared portion. with the main and larger portion of the pivot, by means of a nut 18 in turn adjustably mounted on the outer threaded portion 141 of the bolt. It will thus be seen that the disk 15 is held in a certain and rigid position with respect to the section 1 at all times and the section 2 is provided with a stationary mark 19 positioned so as to cooperate with the graduations 16 on the disk. The graduations 16, of course, are indicative of inches. For example, when the third graduation 16 is arranged in alinement with the mark 19 the pointed ends of the blades are three inches apart.

In order to removably hold the sections 1 and 2 in a stationary and adjusted position a setscrew 20 is mounted through the disk 15 near its periphery and is adjusted so that the inner end will friction-ally engage the section 2 so as to hold it stationary with re-. spect to the section 1.

In the use of the invention as shears, the set-screw 20 is backed out to permit relative freedom of movement of the blades or members 1 and 2, the graduations 7 and 8 on the blades providing for such measurements'as may be desired during the cutting or shearing operation. When using the device as calipers the graduations 16 on the disk are employed and the distance between each succeeding graduation represents one linear unit between the extremities of points t of the blades or members 1 and 2. That is to say, when the initial graduation on the disk is opposite the mark 19 the points 4 are together, but as the latter are separated the graduations on the disk move by the mark until that graduation representing the desired measurement is brought in registration. With the mark 19. The set-screw then is tightened and the points 4 of the blades or members are disposed a linear distance apart equal to the distance indicated by the graduation on the disk Which is opposite the mark 19.

What is claimed is:

An implement comprising complemental sections or legs pivoted together at one end, bolt passing through and securely fixed in one section and engaging the other section, an eyelet disposed in the latter section, the said bolt passing through the eyelet and being formed With a squared portion adjacent the outer face of the eyeleted section, a disk formed With a hole corresponding to the squared portion of the bolt and surrounding said squared portion and lying against the outer face of the section containing the eyelet, said disk having graduations and the eyeleted section having a mark to register With such graduations, a nut threadingly engaged With the bolt and bearing against the disk, and a set-screw threaded through the disk and adjustable to be engaged With the adjacent section whereby the two sections may be locked in angular relation to each other and as indicated by the movement of the mark beside the graduations.

In testimony whereof I aflix my signature.

ALANO E. SUMERSILLE.
