UNITED STATES PATENT O FIGE.
JOSEPH D. HOBBS, OF MEDIAPOLIS, IOWA.
IMPROVEMENT IN BEVELS.
Specification forming part of Letters Patent No. 213,987, dated April 8, 1879; ap
May 18, 1878.
To all whom it may concern:
Be it known that I, J OSEPH D. Hones, of Mediapolis, in the county of Des Moines and State of Iowa, have invented a new and useful Improvement in Tools, of which the following is a specification:
The invention relates to a combination forming in its several arrangements and adiustments the bevel, calipers, compasses, square, try-square, and measurer of slants and angles.
Theinvention consists of a graduated square, Figure I with a corresponding graduated bar, S, with the longer or main arm F, said corresponding bar S joined with the square by a simple coupling-bar, 0.
Fig. I shows a graduated square-shaped tool, with the longer or main arm, F, scalloped within a short space of the end, and the shorter or lower arm, G, with a narrow slot extending nearly its entire length. In this slot is a thumbscrew bolt, B, capable of being moved. along said slot, and tightened when desired. This bolt B also works in another slot extending nearly half the length of the lower end of a graduated bar, S, the counterpart of the longer or main arm, F, of the square, Fig. I. This separate bar S is connected with the main arm F near the elbow of the square by a simple coupling-bar, O, reaching from near the scalloped end of the bar S. This bar Sis also connected with the short arm Gr by the thumb-screw bolt B, which works in a slot extending nearly the entire length of the arm G, and is capable of tightening when desired. This bar 0 works upon a loose bolt, where it is connected with the main arm F, permitting the separate bar S to move at any. angle or slant with the other arms, F and G. This arrangement is capable by proper adjustment of registering any angle of any degree and the sides of any slant, and the main arm F, together with the bar S, may be used as compasses, calipers, bevel-square, try-square, and a measurer of angles and slants.
The operation in the use of said combination applied to a particular case is as follows:
iication filed 1 In getting the size and slant hub of a wheel, the arms F a in the mortise. These are opened, as the case may requ erly fit. When the thumb-scr ened, which holds the arm; position as taken from the the mortise, thereby'register ated arms F and S the exac of said mortise. The spok correspond exactly with this and size, insuring a perfect ing away with the old blo 1 system which nowobtains. Bythis means i secured amore rapid and perfect setting of okes.
So, in setting rafters, the rm G is placed against the upright beam. l e bar S is made to correspond with the rafter readyset,which is the desired slant. The th b-screw bolt B is then tightened, and the. jxact angle and slant are thereby secured. hen the rafters to be set are made to cor pond with this registered angle and slant, m ling every rafter correspond precisely both in lant and angle. This mode makes the settin ore rapid,more secure, and more perfect. i
By a similar process brao and stays may be set, and, in fact, any ,chanical object where angle or slant is a pa 10f the work.
What I claim is- 1 The combination-square h long or main arm scalloped at the end an lgraduated,with a narrow slot in lower ar 1 and loose bar joined with the main arm ar the elbow of the square bya simple coupl' -bar, said coupling-bar reaching from near e elbow of the square to near the scalloped 1nd of the loose bar, which corresponds wi l the main arm, said loose corresponding ba lbeing traversed its lower half length by ana w slot, in which works a thumb-screw bolt, the same time said bolt working in the slot f the lower arm, as described. JOSEP D. HOBBS.
f a mortise in a S are inserted l jither closed or till they propbolt B 1s tightsecurely in its e and slant of g on the gradulant and depth s then made to iegistered slant Witnesses: WM. HARPER, l DANIEL KELLY.
