ATTAGHM ENT FOR SQUARES.
SPECIFICATION forming par-t bf Letters Patent No. 357,771, dated February l5l 1887.
Application filed March 13, 1586. Serial No. 195,134. (No model.) i
To all whom, t may concern.-
Beit known that we, C. DIEDRICH JANssEN and WILLIAM Dn Voir, citizens cf the United States, and residing at rlorrington, in the county of Litchtield and State of Connecticut, have invented certain new and useful Improvements in Drafting-Instruments, of which the following is a specification.
Our invention is a drafting-tool consisting of a block provided with a slot and adapted to receive a pointer or stylus, and to be used in connection with a bar to perform operations ordinarily requiring the use of angles and compasses.
In the drawings, Figure l is a side view of our improved drafting-tool; Fig. 2, aperspective view showing the same applied to a steel square; Fig. 3, a perspective view showing the application in connection with a two-foot rule; Fig. 4, a view illustrating the manner of using a series ofthe tools; Fig. 5, a view showing the manner of using the device as aplumb-bob.
The device consists, essentially, of a block, A, having a recess, a, extending laterally into one side, and a threaded socket, 0:, and a setscrew, B, extending through a threaded opening, y, at the end, so as to enter the recess.
To the socket x is adapted the threaded end of a stylus, drafting pencil or pen, or other tool. One or more of the devices thus constructed is applied to a square, flat rule, or other bar,
D, so that the recess a will receive the edge of the said bar, and the device is then secured in its position by turning the set-screw B so as to clamp it in place.
When lthe block A alone and without the stylus is used, it will serve as a stop to limit the position ofthe bar-as, for instance, in Fig. 2, there are two blocks applied to asteel square in such manner that when they bear against the edge oi' a board, X, the edge of the square will be at an angle to the edge ofthe board, and
A a series of lines, x m', may be scored or drawn upon the face of the board parallel to each other by drawing a pencil or stylus along the edge y of the square, and sliding the latter from time to time along the board, with the blocks A A bearing against the edge. It will be evident that the angle at which the lines .r are drawn may be altered by varying the position of one or the other of the blocks.
Another application of the device is shown in Fig. 3, in which the bar consists of an ordinary two-foot rule, and the blocks are applied thereto near the opposite ends,each block carrying a stylus or pointer, J, one of which serves as a center or pivot, around which the other is carried by swinging the rule'so as to score a curve or circle upon the surface to be marked.
-In Fig. l is illustrated a series of devices applied to a single bar, four ofthe blocks being provided with short pointers, while each end block has a long pointer, which serves as a guide bearing against the edge of the board, which is readily scored in parallel lines by drawing the bar and the parts supported thereby over the surface of the same.
There it is desired t produce a more legible mark, a pencil or drawing-pen may be substituted for the stylus J.
It will be seen that the above-described device, while cheaply constructed and easily applied te any bar, may be readily made the means of economically performing operations ordinarily requiring the use ofexpensive drafting-tools.
IuFig. 5 another application of the device is shown, in which a metallic filling-piece, b, is adapted to the recess a, and a hole is drilled through the set-screw B for a line, fu, the device then forming a plu1nbbob.
We are aware that it has been proposed to apply to a square a longitudinally-slotted blocl; having at one end a set-screw entering the slot, so as to secure the block adjustably on the square, and having at the other end a iixed pointer. Such a construction, however, is limited in its use, as it can be applied to one arm only of a square, and cannot be used as a stop, nor can other tools be substituted for the pointer. We are also aware that it has been proposed to use a U -shaped piece of sheet metal having an integral pointer and a set-screw, so as to be placed at any point on a square or rule; but such a device cannot be used as au adjustable stop and the pointer cannot be replaced by other tools. Our device, however, is distinguished from the above-mentioned devices in that we use a block having a lateral recess in one side, a set-screw in one end and entering the recess, and a threaded socket at IOO vIO
-the other end for the reception of tools.
The lateral recess in the block adapts it to be applied at any point on a rule or square and project laterally above and below the same, and thereby form an adjustable stop, the operation of which is apparent from Fig. 2 of the drawlIJS.
aVithout limiting ourselves to the precise construction and arrangement of parts shown, we claim- 1. A block, A, having a recess extending 'transversely into one side and a set-screw, B, extending into one end of the block and entering said recess, whereby the block may be placed and Vsecured on the edge of a rule or square at any point within the length and irrespective of the width thereof and project at right angles to said rule or square to form an adjustable stop, substantially' as described.
2. A block,`A, having a recess extending transversely into one side to receive the edge of a rule or square, a set-screw, B, on one end and entering the recess, and a threaded socket in the opposite end for receiving a removable pointer, stylus, or other tool, substantially as described.
3. The combination, with a rule, of one or more blocks, A, having set-screws B at one end, removable pointers J, and transverse recesses entered by the set-screws and adapted toreceive the edge of the rule, whereby the blocks will project at right angles to the saine,
