COMB INATION BEVEL Filed Sept. 2, 1945 3 Sheets-Sheet 3 Patented July 27, 1948 UNITED STAT ES PATENT OJFF I-CJE 2,446,067 i a COMBINATION BEVEL William Thomas, San Francisco,: (lali. Application September 2, 19 43, Serial'No. 500,962
This invention relates to a combination bevel, protractor, center head, gauge, compass, square, and in fact a general purpose instrument with the result attained by interchanging of the relation of the parts, and for individual use thereof, in coaction, or combination.
I aim to provide an instrument of the present general character which is an improvement over that especially disclosed in my copending application Serial No. 465,341, filed November 12, 1942.
The more specific objects and advantages will become apparent from a consideration of the description followingtaken in connection with accompanying drawings illustrating an operative embodiment.
In said drawings:
Figure 1 is a view in side elevation of my improved structure adjusted to the form of a square and having a center head attached thereto;
Figure 2 is a side elevation showing the parts of the invention secured in position for use as a gauge;
Figure 3 is a sectional view taken on the line 3-3 of Figure 1;
Figure is a cross section taken on the line 4-4 of Figure 1;
Figure 5 is an elevation showing the parts in adjusted position for use as a bevel;
Figure 6 is 'a detail section taken on the line 6-6 of Figure 1;
Figure 7 'is a detail section taken on the line '|-'I of 'Figure 1; Y
Figure 8 is a view showing the blade detached and used in connection with a board and peep sight;
Figure '9 Ba view in plan of said blade andpeep sight;
Figure '10 is a section takenon the line It-til of Figure 8, with the board omitted; and
Figure 11 is-an elevation showing the partsin adjustment for use as a square.
Referring specifically to the drawings wherein, like reference characters designate like orjsimilar parts, a'st'ock'isprovided as at H) comprising two plates ll preferably separably connected together as by a pivot bolt at l2 passing through suitable openings, and which pivot bolt 12 at It may be pointed to enable it to occupy the depression made by a center punch mark or the equivalent. In addition, any suitable bolt may be .passed through registering openings or holes l4 adjacent one corner of the plates ll. Such plates may or may not be provided, along their longitudinal edges and end edge or otherwise, with flanges as at I5.
1 Claim. (01. .33-102) Such plates H have central longitudinal s'lots It with ail-enlargement ll adjacent the free end of the plate-whereby levels 18 and P9 that function like those in my aforesaid pending application may be optionally disposed. Such levels have stems 20 adapted to slide in the engaged slots i8 and they have feet 21 passable through either of the slots or enlargements Fl ans adaptedto overlaptheplates between them. desired clamping pressure may :be applied to-the plates to clampthe feet 2] between the plates, by the bolt which occupies the openings 1'4.
It will be noted that the plates It on their outer surfaces-are suitably calibrated, andfit is to be borne in mindthat on such surfaces or on any other surfaces of theinstrument or its components one may stamp, etch, or otherwise delineatesuitable tables, equations concerning the pitch, degrees, rises, and hypotenuse, or any other desired data.
Pivotally mounted -on the bolt 12 with oneend disposed "between the inner ends of theplates H is a blade ortongue generally designated 22, the same being adapted for disposition ,at any desired angle, such as for use as a"sq'uare *asin Figure 1, a bevelas in Figure 5, or asquare as in Figure "11.
The adjustment of the blade 22 to these flit-- ferent positions is permissible since it has a slot generally of L shape consisting of communicating branches 23 and 24*. However, thebladeis adaptedto swing when thebolt l2 isat the-intersection of the branches 23 and 24, 's'irrce-itsgin ner edge under suchconditions is in line-with the pivotal axis ofthe 'bolt *l2 as in'Figure Itwill be noted that the blade 22 "alongits oppositerlong-itudinal edges has suitable calibrations .at {25 and 26 and that along its arcuate edge ijtgis provided with protractor calibrations or indications 2'1. Viewing the blade as in Figure 1, the indie cations-25 and 26 being in inches, zero .startssat the longitudinal median line {of the stock "Infill-2 terseeting the center 301 the bolt "l2.f Th-efblade.
22 has a centrallongitudinal slot 28" extendi'ng inwardly from one end and also has an arcuate slot 29 concentric with the center l2 and protractor calibrations 21. Slot 28 will accommodate the use of either level It! or H3. or any equivalent or other accessory therein.
In Figure 2 I have shown the parts described in position for use as a gauge. It will be noted that one end of the blade 22 extends below the stock to for gauging purposes, the lower edge of the stock In being adapted to rest on a board or piece of work being gauged. Also the blade 22 gauging purposes, in view of the elongation of the slot 23.
In Figure 4 I have shown a bolt at I la occupying the openings I4. This bolt may be conventional or it may have a center punch llb thereon for marking purposes; and also to enable it to occupy or enter a mark in connection with its work.
In Figure 5 the parts described are shown adjusted to a position where the structure forms a bevel. It will be noted that the blade 22 extends on one side of the stock or one of the plates ll, while the other plate is at an angle on the other side of the first-mentioned plate I l.
It will be noted from Figures 5 and 6'that the levels or other accessories such as [8 and 19,.
which here are designated 18a and I90. respectively, have a different or modified form of means whereby they may be mounted in the slots I 8, 2B, or the equivalent. .To this end spaced spring fingers 30 extend from each and they have on their outeredges spaced-apart projections 3| and 32, providing notches 33 between them. Such fingers 30 are tensioned to spring apart slightly at their free ends, and as a result will frictionally remain in place. The plates ll, blade 22, or other parts are adapted to be engaged in the slot by the notches 33 ;with the projections 3| and 32 being disposed on opposite sides of them.
As best shown in Figures 1 and 6, I may use a center head in connection with the structure, the same being generally designated 0. This center head may be usedfor various purposes, as in finding the centers of shafts, cylinders, and various other: purposes. It consists of one bar 34 of L shape, preferably in one piece and rigid, and a, pairof separate :bars 35 conforming to the wings or angles thereof, not touching each other, as shown in Figure 6, to accommodate connection to parts where there isa flange. Said bars 34 and 35 are connected together by clamping bolts 36, and it will be noted that oneof them passes through the opening or slot 28 to secure the center head to the blade 22.
, In Figures-8, 9, and the blade 22 is shown detached and as when used in connection with a board31. In such use a peep sight of general construction-38 also may be used, the level line being indicated at 39. This peep sight has mounting fingers at 40 arranged to spring together at their inner ends and having lugs 4! thereon whereby theyadjustably may engage the arcuate slot 29 or the elongated slot 28, as preferred for the particular use and according to the shape of the particular lug. It also will be seen in Figure 8 that the fingers 40 have elongated slots 42 to enable them to accommodatea bolt to fasten the center headC thereto or to accommodate the mountings or levels or other accessories such as those at 28 and 30. r I i i i In Figure 11 the structure is shown in the adjustment at which it is capable of use as a square. It particularly will be noted that this use is possible since the shorter slot or branch 24 at its closed end is in engagement with the pivot bolt I2.
The plate ll, blade 22, and bars 34 and 35 may be of metal, plastic, or otherwise and sufiiciently pliable or flexible to adapt themselves on round or uneven surfaces.
It will be understood that I have discussed the use of the invention and its parts in only a general way and that such invention and parts are not to be restricted to the uses suggested, but are capable of broad and general application.
Various changes may be resorted to provided that they fall within the spirit and scope of the invention.
I claim as myinvention:
A structure of the class described comprising 'a stock consisting of spaced plates, a blade, a bolt pivotally'and slidably securing the blade to the stock for disposition of a portion of the blade between the plates of the stock, said blade having a substantially L-shaped slot engaged by the bolt and including a portion extending substantially longitudinally of the blade for adjustment of the blade longitudinally of the stock when said parts are disposed substantially parallel, said blade being of a length to extend adjustably beyond the free end of the stock to serve as a gauge with said free end engaging the work, said slot permitting pivotal adjustment of the blade to various angles and positions relatively to the stock to form a bevel or square and with said bolt disposed in various portions of the slot, and said slot having an arcuate enlargement at its apex in which said bolt is normally disposed when the parts are positioned to form a bevel or square.
WILLIAM THOMAS.
