rlbe invention primarily has for its b-z ject to provide a novel combination tool which is adapted or use by carpenters and other mechanics and which combines in a [d single simple, compact and inexpensive article a try-squareflmitre and bevel squares,
calipers, Compasses and scribers.
Another object 'of the invention is to pro vide means to pivotally mount a plurality l@ oi blades on a common pivot and in a manner enabling the securing of one blade inn dependently of another blade.
Jd notlier object of the invention is to provide a novel blade slide for use in holding a marking element during scribing and arc describing operations.
Another object oi the invention is to provide novel nieans for ellecting scribing and are describing operations.
Another object oi the invention is to construct the main body or handle ot my iinproved implement in a manner enablin it to accommodate the mounting of a plurality oif blades itliout materially affecting tlie strength and compactness thereof.
Other objects will in part be obvious and in part be pointed out hereinafter.
rllo the attainment olf the aforesaid obects and ends the invention further resides in the novel details of construction, combination and arrangement of parts, all ci which.
will be first fully described in the followingJ detailed description, then be particularly pointed out in the appended claiins, reference being had to the accompanying drawings, in Which:-
Figure lv is la tace view illustrating the invention.
Figure 2 is an enlarged cross section taken on the line 2 2 on Figure 1.
Figure 3 is a longitudinal section taken on the line 3-3 on Figure l.
Figure 4; is a cross section taken tbrougli the blade slide.
Figure 5 is an enlarged fragmentary face view of the blade slide, parts being broken away.
Figure 6 is a view similar to Figure 5 and illultrates. a modied construction of slide loc Figure 7 is a cross section taken on the line 7-7 on ligure 6. Figure 8 is a face view illustrating a moditied forni oi' the invention.
Figure 9 is a longitudinal section taken on the line 9-9 on ligure 8.
ln the .practical development oi tbe vention l employ a ,I air oft handle stock bodies l and securely olt or rivet them togetlier as at 2 in opposed spaced relation. At one end a blade 3 is secured between the bodies l to project therefrom in right angular relation and form a try-square blade.
The steelt bodies l are preferably reduced as at l at one side ci one end to 1Storm on eacli said body pivot eye extension 5 tlirougn registering awrtures in which a pivot bolt 6 is projecteditor a purpose to be described later. y l
A divider plate l is secured in centrally spaced relation between the bodies l, suitable filler pieces 8 being interposed between the opposed faces .of the plate and said bodies to suitably position the divider plate and to forni a composite solid back edgel at one side of tlie handle structure and open blade receiving spaces at the other side of the handle structure. lior this purpose the filler pieces are approximately half as Wide as the stoclr bodies, thus providing a handle structure solid tln'ougli approximately halt its width and having two separated blade reu ceiving spaces in its remaining half which are of approximately the same Width as tbe extensions 5. lt will also be noted that the iller pieces 8 terminate short of the pvot eyes formed by the extensions 5 thus leaving said extensions resilient .and tree to be pressed toward each other and the divider plate 'for a purpose that will soon be apparent.
A securing bead 9 is carried by the bolt (i at each side of and in engagement with tbe divider plate 7 and these heads securely hold tbe bolt against any attempt to withdraw it from the pivot eyea l A. mitre square blade 10 is accommodated in each of the handle blade receiving spaces and each said blade is provided with a longi tudinal slot 11 to receive thepivot bolt 6 and Etf dit
to enable the blade to be longitudinally ad um justed on its pivotal mounting provided by said bolt. In addition to serving their usual purpose at least' one of the blades 10 is constructed of such a length that it may be 5 extended to engage the try-square blade and vider plate 7 The bolt 6 being secured to the divider plate 7, means is provided for individually and independently adjusting and securin the blades 10. Either blade may be readlly adjusted and secured without disturbing the secured adjustment of the other bla 4 The device is also adapted for use as a compass for describing arcs or circles. For this purpose one end of the bolt 6 may be pointed as at 13 to provide a fulcrum point, and one or both blades 10 may be provided with one or more pencil receiving notches 14. By adjusting the proper blade longitudinally to obtain the desired radius and securing the adjustment, the desired arc or circle may be described by lacing the point on the surface to be marked) and turning the device about the fulcrum point while holding a pencil-point in the blade notch and in engagement with said surface.
To facilitate the adjustment of the blade to obtain the desired radius, said blade or blades may be provided with measuring scales 15 by which the distance of the selected pencil holding notch from the fulcrum point may be quickly determined.
By employing the pencil holding notches in cooperation withthe handle body instead of with the fulcrum point, the device may be employed as a scriber.
The try-square blade may be made plain asin ordinary try-squares or it may be made thicker and provided with a longitudinal slot 16 to receive an adjustable pencil holding slide 17. The slide carries a cam member 18 which may be moved into engagement with a wall of the blade slot to secure the slide at adjusted positions. See Figure 5.
In Figure 6 I have shown a modified form of slide which is provided with a centrally positioned slide rod 19 having fixed thereto a light s ring 20 which normally has its ends projecte through side openings 21 inthe slide into engagement with the milled walls 22 of the slot. By moving the rod longitudinally the spring ends may be retracted from engagement with the slot walls to permit the slide to be moved to a new adjustment, and when the rod is released the spring ends will again engage the slot walls to lock the slide to position. i
Thus the slide 17 may be employed as an abutment against which to hold a pencil point or other marker for cooperating with the handle body in effecting scribing operations. The blade may also be apertured at 23 to receive a suitable removable fulcrum point 26 and thus enable the describing of arcs and circles. To facilitate these operations, and also to enable ordinary measuring, the blade 3 may be provided with suitable scale markings as indicated at 24.
One or both stock bodies 1 may bebevelled at 25 at the try-square blade receiving end to enable use of the blade for a bevel try as Well as the usual right angle try.
From the foregoing description, taken in connection with the accompanying drawings, it is thought that the novel details of construction, the manner of use and the advantages of the invention will be readily apparent to those skilled in the art to which the invention relates.
What I claim is:
1. In a device of the character described, a pair of stock bodies, means securing said bodies together in parallelism, a plate secured between said bodies and dening therewith a pair of blade receiving spaces, longitudinally slotted bevel blades mounted in said blade receiving spaces, means securing said bevel blades at one end of said stock bodies, a try-square blade rigidly secured at one end between said stock bodies at the other end thereof, and lying at right angles thereto, said try-square blade being of a thickness approximately that of the combined thickness of said plate and said blade receiving spaces, said trys uare blade havin a longitudinal slot, a slide operable in sai slot, and means located within the slide and including a portion projecting through one end thereof for clampin the slide to the edges of the try-square bla e at the slot for holding the slide in an place desired along the slot.
