GEORGE F. HALL, OF NEWARK, NEW JERSEY, ASSIGNOR OF ONE-HALF T0 DELANCEY P. HARRIS, OF NEW YORK, N. Y.
COMPOUND INSTRUMENT.
Specification of Letters Patent.
Patented July 11, 1911.
To all whom it may concern:
Be it known that I, GEORGE. F. HALL, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Compound Instruments; and I do hereby 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, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.
The present invention relates, generally, to improvements in compound instruments; and, the invention refers, more especially, to a combined tee-square, bevel and triangle, the same being capable of adjustment to provide a wide range of angles of varying degree. 7
The invention has for its principal object to provide a neat, compact, and simply constructed device of the character herein set forth, the same being adapted to beused for many purposes, but being more especially adapted for use as a combined square and bevel, as well as a draftsmans appliance adapted to perform the functions of a teesquare and triangle in such a manner, so as to render very easy of accomplishment such drafting operations as the laying out of irregular angles, sectionizing, and other similar operations. I
Other advantages of the present invention, and other uses to which it may be put, will be readily understood from an inspection of the accompanying drawings, as well as from the following detailed description of the invention.
This invention consists, primarily, in'the novel construction of compound instrument hereinafter set forth; and the invention consists, furthermore, in the novel arrangements and combinations of the various parts, as well as in the details of the construction thereof, all of which will be hereinafter more fully described in the following specification and then finally embodied in the clauses of the claims which are appended to and which form an essential part of this specification.
The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a plan View of the novel compound instrument, embodying the principles of my present invention, the dotted lines of said figure indicating two extremes of the various adjusted positions of the adjustablehead of said instrument; Fig. 2 is an edge view of the same looking from right to left of said Fig. 1; Fig. 3 is a horizontal section of the same, taken on line 33 in said Fig. 1; and Fig. 4: is a similar section, taken on line 44 in said Fig. 1, both of these sections being viewed in the direction of the arrow a. Fig. 5 is a detail cross-section, taken on line 55 in said Fig. 1, this view being drawn upon an enlarged scale; and Fig. 6 is a bottom edge-view of the instrument.
Similar characters of reference are employed in all of the said above described views, to indicate corresponding parts.
Referring now to the several figures of the said drawings, the reference-character 1 indicates the complete compound instrument embodying the principles of the present invention, the same comprising a main body-portion 2 provided with a straight edge 3, and a suitable or convenient scale 4 located along the said straight edge 3, said scale comprising any suitable space-division or graduations. Extending from one end of said main body-portion 2, and preferably at an angle of forty-five degrees therefrom, is an angle-arm 5. Pivotally connected to said angle-arm 5 and adjacent to the free end thereof, by means of the pivot-member 6, is an adjustable head 7 The said adjustable head 7 comprises a plate or sheet of metal which is bent or doubled upon itself so as to'form a pair of forwardly extending members 8 and 8 registered one above the other in such a manner so as to leave an in-.
tervening space 9 adapted toreceive therein the said, body-portion 2 and the angle-arm 5, so that said forwardly extending members 8 and 8 are respectively arranged one upon eaohside of said body-portion 2 and said angle-arm 5. The doubled-over edge 10 of the said adjustablehead 7 is provided at its free end with a short inwardly extending slot 11, sufficiently deep to allow the'free endsof the respective forwardly extending members 8 and 8 to extend over and upon the respective sides of said main body-portion 2. The said doubled-over edge 10 is further provided with another slot 12 which extends from the pivoted end of said adjustable head 7 outwardly to within a short distance of the inner end of said inwardly extending slot 11, this said slot 12 permitting the respective forwardly extending members 8 and 8 to extend over and upon the respective sides of the said anglearm 5. The said forwardly extending members 8 and 8 are each provided upon one of their longitudinal edges with a flange 13 and 13 respectively. The said flanged edges of said forwardly extending members 8 and 8 are joined to a flange-plate 141, the longitudinal edges of which are turned over and around said flanges 18 and 13 so as to form outwardly extending ribs 15 and 15 the same extending at right angles to the respective members 8 and 8 The said flange-plate 1 1 is also provided with slots 16 and 17, the same being respectively opposite the abovementioned slots 11 and 12. The said free ends of said forwardly extending members 8 and 8 are preferably chamfered or cut so as to form a finder or indicating point 18, which serves in connection with a proper scale 19, indicating degrees of angles with which the said main body-portion 2 is provided. The said forwardly extending mem bers 8 and 8 are provided with slotted por tions 20 and 20 the same being located at or near the free ends of said forwardly extending members 8 and 8 and extending parallel to and within a short distance from the respective ribs 15 and 15 These said slotted portions 20 and 20 are further adapted to register one above the other. Movably arranged within said slotted portions 20 and 20 and adapted to project therethrough is a bolt 21. Arranged upon the shank of said bolt 21 are washer- like members 22 and 22 adapt-ed to engage the respective outer surfaces of said forwardly extending members 8 and 8 The said members 22 and 22 are respectively provided with the straight-edges or portions 23 and 23 which are adapted to engage the inner sides of the respective ribs 15 and 15 in such a manner, so as to prevent said members from turning. Said bolt 21 is further provided at its free end with a screwthreaded portion 24 adapted to receive a thumb-nut 25. WVhen said adjustable head 7 has been arranged, so as to produce in connection with said main body-portion 2 and its angle-arm 5, any desired angle or bevel, the said bolt 21 is moved in said slotted portions 20 and 20 until it is brought against the inner edge of said main body-portion 2, the said thumb-nut 25 is then screwed down tightly so as to cause the respective washerlike members 22 and 22 to bind upon and force the free ends of the forwardly extending members 8 and 8 in tight binding engagement with said main body-portion 2, thus causing the said adjustable head 7 to be firmly and securely held in its adjusted relation to produce the desired angle or bevel. Secured by means of screws, or in any other suitable manner, to the upper surface of said adjustable head 7 is the baseplate 26 of a spirit-level 27, thus providing in connection with the other novel features of my present device, the additional function of a spirit-level. The said main bodyportion 2 is further provided with a perforation 28, the same being formed with a wedge-shaped cut-away portion 29 the bottom of which is opposite one of the main graduations of said scale 4. In like manner, said main body-portion 2 is provided with a plurality of perforations 30 each having a wedge-shaped cut-away portion 31 the bottom of which is opposite one of the main graduations of said scale 4:. These perforations serve as a means for striking a wide arc, or the like. The manner of their use is as follows :A sharp instrument, such as a brad-awl, or the like, is inserted in the perforation 28 so as to be engaged by the bottom of said cut-away portion 29; in like manner a pencil, or other marking device, is inserted in any one of said plurality of perforations 80, so that the point thereof is engaged by the cutaway portion 31, and by swinging the main bodyportion 2 upon said brad-awl, as a center, the pencil, or other marking device may be caused to strike a circle, arc, or the like, as will be clearly understood.
It will be clearly apparent, that the novel device constructed and combined in the manner above described, will readily lend itself to the accomplishment of many purposes; and, its use will be found serviceable not only in drafting and such kindred operations, but in building and construction work of various kinds.
I am aware that changes may be made in the various arrangements and combinations of the several parts without departing from the scope of my present invention. Hence, I do not limit my invention to the exact arrangements and combinations of the parts as herein described and as illustrated in the accompanying drawings, nor do I confine myself to the exact details of the construction of the said parts.
