RU LER AND PAPER-CUTTER.

SPECIFICATION forming part of Letters Patent No. 552,988, dated January 14, 1896. A plication and June 15,1895. secure. 552,943. on model.)

To all whont it may concern:

Be it known that I, EBENEZER P. DAVIES, a citizen of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented a new and useful Ruler and Paper-Cutter, of which the following is a specification.

This invention relates to an improvement in rulers and paper-cutters, and has for its object to provide a simple, convenient, and eflicient combination device which shall combine a ruler, a blotter for removing ink therefrom, and a paper-cutter, which may also be used as a paper-cutter and a measuring-rule.

A primary object of this invention is to utilize the ordinary round ruler in connection with a carrier-frame by means of which such ruler may be manipulated and controlled.

A further object of the invention is to provide such round ruler with metallic end caps or ferrules, which are graduated and adapted to be used in' connection with a pointer at either or both ends of the frame in which the ruler is mounted, for enabling the operator to space the lines at the same or any desired distance apart.

' Other'objects and advantages of the inven tion will appear in the course of the subjoined description.

In order to accomplish the objects above mentioned, the invention consists in certain novel features and details of construction and arrangement of parts, whereby advantages in point of simplicity and eiiiciency are attained, as hereinafter fully described, illustrated in the drawings, and finally embodied in the claims.

In the accompanying drawings, Figure 1 is a perspective view of a combined ruler and paper-cutter constructed in accordance with this invention and looking towardthe rear thereof. Fig. 2 is a similar view looking toward the front of the device. Fig. 3 is a transverse vertical section through the same. Fig. i is also a transverse vertical section showing the blotter in the form of a cylindrical roller.

Similar numerals of reference designate corresponding parts in the several figures of the drawings.

Referring to the accompanying drawings, 1 designates an ordinary round ruler, which may be made of wood or any preferred material and of any desired length and diameter. For the purposes of carrying out this invention, the ends of said ruler have applied thereto a pair of metallic caps or ferrules 2, the annular flanges or portions of which are graduated for a purpose that will appear. This round ruler is journaled at its ends in a pair of end brackets or frame-plates 3, which are substantially triangular in shape and have interposed between them several connecting bars or rods, which contribute to form a stout rigid frame, by means of which the ruler 1 may be controlled. These end brackets or frame-plates are provided each with an integrally-formed spur a, which performs the office of a pointer, and which, when used in connection .with the graduated caps or forrules upon the ends of the round ruler, enable the operator to properly space the distance between the lines.

5 designates the paper-cutter, which consists of a flat strip of metal, riveted or other wise secured at its ends to said end plates 3, said strip being beveled or chami'ered off at its rear edge to facilitate its operation as a papercutter, and being also provided with a series of graduations corresponding to the graduations on an ordinary foot-rule, as shown.

6 designates a top bar, which extends across between the upwardly-projecting ends of the triangular end plates and is riveted thereto, said barbeing round in cross-section and constituting the handle of the device, by means of which the same may be grasped and moved across the surface to be ruled.

Iuterposed between the stationary papercutter and the handle 6 is a pair of approximatelywertical braces S, and interposed between and connected with said braces is a central horizontal thumb-rod S), which is adapted to receive the thumb of the operator for enabling the device to be more thoroughly steadied by the operators hand.

10 designates another rod, which is interposed between the end plates 3 and is arranged in close proximity to the round ruler 1. A sheet or strip of blotting-paper or other absorbent material 11 is looped at its central portion around this rod 10, and the terminals or opposite edges of said strip of blottingpaper are tucked or inserted between the ruler 1 and a small longitudinal rod 12, interposed between and connected with the end plates and located near said ruler. The relative disposition of the revoluble ruler and the longitudinal rods 10 and 12 is such that the blotting-paper is held normally pressed against and resting in contact with said ruler. A pair of spring-clasps 13 are applied to the rod 10 and the blotting-paper or other material extending around the same, for holding said paper firmly thereon. By pressing said clasps rearwardly or toward the paper cutter, it will be seen that the blotting-paper may be pressed still more closely against the ruler 1.

If preferred, the rod 10 may be omitted and replaced by a roller extending longitudinally of the device and journaled at its ends in the end plates 3, said roller being covered with blotting-paper or equivalent absorbent material, as indicated in Fig. 4. This construction will dispense with the strip of blotting-paper 11, rod 12, and spring-clasps referred to. By means of either of the constructions described, however, it will be apparent that I am enabled to utilize a round ruler, which is acknowledged to be the best form of ruler in existence and to thoroughly control the movements thereof by means of the frame above described. By means of the graduated end cap or ferrules upon said roller, in connection with the pointers on the end plates, the lines may be spaced the same or any desired distance apart, and by reason of the particular arrangement of blotter referred to the liability of the ink beingcar ried by the revoluble ruler to the paper or surface being ruled is entirely obviated. The distance between the point of contact of the ruler and the paper-cutter is of such extent that any desired amount of pressure may be applied to the handle-rod at the top when used as a paper-cutter or ruler. It will also be apparent that by the construction described all applied pressure and weight are thrown upon the ends of the round ruler, thus enabling the latter to move with accuracy across the surface to be ruled, and preventing all liability of the same from twisting as in the case of an ordinary ruler where the pressure is applied at the center. If desired, notches 14 may be formed in the vertical braces between the paper-cutter and the handle-rod at the top, thus providing for the reception of a penholder.

The combination ruler, paper-cutter, 850., above described will be found of the greatest possible convenience and utility in office and school work. It is very simple in construction, can be manufactured at very slight cost and will effect a great saving in time over the ordinary ruling devices in common use.

Changes in the form, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is
