CARPENTERS TOOL.
Specification of Letters Patent.
Patented Nov. 24,1914.
Application filed November 4, 1912. Serial No. 729,514.
To all whom it may concern I Be it known that I, THEODORE H. SMITH, a citizen of the United States, residing at Richmond, in the county of Henrico and State of'Virginia, have invented a new and useful Carpenters Tool,'of which the following is a specification.
The tool herein described is adapted to be.
employed for locating the radii of segmental rings, for laying otf angles other than .a
right angle, for laying off right angles, as a straight edge and as a try-square.
One object of the present invention is to provide a body member of novel form, along which studs are adapted to slide, to permitthe fiducial position of the tool to be employed in laying off the radii of segmental rings, in defining angles other than a right angle, and under other circumstances which will suggest themselves readily to the user.
The invention aims, further to provide novel meansfor assembling the studsslidably with the body.
It is within the scope of the invention to improve generally and to enhance the utility of, devices of that type to which the present invention appertains.
IVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention can be made within the scope of what is claimed without departing from the spirit of the invention. 7
In the drawing :-Figure 1 shows the invention in side elevation; Fig. 2 is a top plan; Fig. 3 is asection on the line 83 of Fig. 2; Figs. 4, 5 andG are plan views showing various applications of the tool, Figs. 4, 5 and 6 being diagrammatic in nature; Fig. 7 is a perspectiveof one of the plates with which certain of the studs are assembled; Fig. 8 is a longitudinalsection of that stud which cooperates withthe plate shown in Fig. 7; Fig. 9 is a perspective of another stop plate; and Fig. 10 is a longitudinal section of the stud which cooperates with the stop plate shown in Fig. 9.
In carrying out the invention there is provided a tool 1 which is in the form of a Latin cross. The tool comprises a body comprising parts 2 and 3, the part 2 being graduated along one edge as indicated at 1.
The tool further includes alined, oppositely extended arms 5 and 6, disposed at right angles to the body 1. In the arm 5 there is a longitudinal slot 7 and in the arm 6 there is a longitudinal slot 8. The slots 7 and 8 at their inner ends terminate short I of the longitudinal center of the body 1. In the body 1 there is a longitudinal slot 9 eX- tended across the line of juncture between the body 1 and the arms .5 and 6.
Studs are mounted to slide. in the slots 7, 8 and 9, and in order to facilitate the description of the operation of the-tool, the primary stud which is slidable in the slot 9 y is denoted by the numeral 10, the numeral 11 indicating the secondary stud which is slidable in the slot 7 and the numeral 12 indicating the secondary stud which is slidable in the slot 8. p
A detailed description of the several studs Wlll. now be given, and, thereafter, the studs will be referred to by their general reference characters 10, 11 and 12.
The'studs 11 and l2 are of identical con 'struction, and a description of one of them will suffice for both. Each of the studs 11 and 12 comprisesa cylinder 14 whichbears against one face of one of'the arms 5 and 6, the arm 6 beingconsidered in the present instance. The cylinder 14 is provided with a fiat end 15 which registers slidably in the slot 8, but engages the edges of the slot ,8 against rotation. The cylinder 1a is equipped with a threaded bore 16, receiving one end of a screw 17 which extends through the slot 8. The screw 17projects through an opening 18 in plate 19, adapted to engage the other face of the arm 6, the plate 19 having along its longitudinal edges, tongues 20 which register in the slot 8. At its ends, the plate 19 is equipped with up standing finger pieces 21. A set nut-22 is threaded upon the protruding end of the screw 17 and bears against the'plate 19, so that the arm .6 is clamped between one end of the cylinder lei and the plate 19. From the foregoing construction it will be obvious that the cylinder 14. may be clamped at any position intermediate the ends of the slot 8.
The slot 9 in the body 1 is somewhat narrower than the slots 7 and 8 in the arms5 and 6, and the stud 10 which cooperates with the slot 9 is of slightly different construction fromthe studs 11 and 12. In constructing the stud 10, a cylinder 23 is provided, one end of the cylinder 23 abutting against one face of the body 1. The cylinder 23 is equipped with a threaded bore 24, receiving one end of a spindle 25 having an enlarged, flattened part 26 which registers in the slot 9 against rotation, the spindle 25 terminating in a threaded head 27 extended through an opening 28 in a plate 29 adapted to bear against the other face of the body 1, the plate 29 having struck therefrom, tongues 30 which are received in the slot 9. At its end, the plate 29 is provided with upstanding finger pieces 31. A set nut 32 is threaded upon the head 27, and it will be seen that by rotating the set nut 32, the cylinder 23 may be clamped at any point along the body 1.
Some of the uses to which the tool may be put, will now be described, other uses suggesting themselves readily to the user.
Suppose, referring to Fig. i, that it is desired to lay off the radius of a segment of a ring. The studs 11 and 12 are moved to the remote ends of the slots 7 and 8 respec tively, if the ring is of large radius, or to the adjacent ends of the slots 7 and 8, if the ring is of small radius. The studs 11 and 12 are then placed against the outer edge 13 of the ring, and the stud 10 is moved in the slot 9 until it abuts against the edge 13. If, then a mark be made upon the ring, through the slot 9, the radius of the ring, or a line defining one end of a ring forming section, will be laid off. The same result can be accomplished by placing the three studs 11, 10 and 12 in abutment with the inner edge 33 of the ring. If the tool is moved to the left until the stud 11 rides off one end of the segment, the studs 10 and 12 will still position the slot 9 radially of the ring. If the tool be moved to the right until the stud 12 rides 0d the right hand end of the segment, the studs 11 and 10 will maintain the slot 9 radially disposed.
Referring to Fig. 5 it will be seen that the studs 11 and 12 may be clamped at any points in the slots 7 and S, the stop parts 21 being placed against one edge 38 of the material, so as to prevent the edge 10 of the tool from overlapping the material. A pencil is passed along the edge 37 of the part2, to define a right angle with the edge 38 of the material, and the mark thus made will extend to the edge 38 of the material, because the parts 21 and 31 prevent the edge A0 of the tool from overlapping the material. Suppose, however, that the line along the edge 37 is to be drawn so close to the edge 39 of the material that the stud 12 and its part 21 cannot be used to an advantage. Under such circumstances, a straight edge, or the edge 38 of the material may be brought into engagement with the parts 21 of the studs 11 and 12, the stud 10 being then moved until its part 31 abuts against the straight edge or against the edge 38 of the material.
Then, if the tool be advanced toward the edge 39 until the stud l2 lies beyond the edge 39 the parts 31 and 21 of the studs 10 and 11, engaging the edge 38 of the material,
will position the edge 37 of the tool at right angles to the edge 38. llt will be understood readily that the edge 1-0 of the arm 6 and the edge 37 of the part 2, being rectangularly disposed, may be employed as a try-square. Any other corresponding edges of the tool having a like relation may be used similarly.
In Fig. 6 another operation is shown, and suppose that it is desired to lay off an angle which is greater orless than a right angle. Under such circumstances, the stud 11 is clamped in place in the slot 7 and the stud 10 is moved along the slot 9 until the center of the stud l0 registers upon one of the graduations 4 of the part 2 of the body, these graduations A being so marked as to represent different angles between the edge 4L1 of the part 2 and the edge 12 of the ma terial. If a pencil be passed along the edge l1, an angle will be defined with the edge 42, and this angle will correspond with the appropriate graduation 4-.
In practice, all parts of the tool are fashioned from metal, although any other structural material may be employed when expediency demands.
Having thus described the inventioi'i, what is claimed is 1. A tool of the class described compris ing in a rigid structure, a body and alined oppositely extended arms disposed at right angles to the body; studs; means for mount ing the studs on the arms for right-line movement longitudinally of the arms; another stud; means for mounting the last named stud 0n the body for right-line movement longitudinally of the body into and out of alinement with the studs on the arms; and means 'for holding the studs against movement.
