MULTIPLANE BEVEL SQUARE.
Application filed June 24, 1926', Serial K10 118293. Renewed May 1, 1928.
This invention relates to bevel squares and particularly to certain improvements on the structure shown. in Patent No. 897,104 granted to Carl M. Hoeregott on August 25, v
' Thegeneral object of this invention is to so improve this bevel square that it willbe more certain in its action, may be more readily adjusted, that the parts will be more positively held in their adjusted positions, that there will be less liability of wear and that the square will be rendered stronger and more rigid. I 7
Another object is to so construct the squarethat the marking blades thereon may be readily set without the necessity of using a steel square forthe purpose.
Sill another object is to so construct the bevel square that it may have a wider range of use than was possible with the original structure. I
My invention is illustrated in the accompanying drawings wherein Figure 1 is a top plan view ofa bevel square constructed in accordance with my invention; v I
Fig. 2 is a perspective View of one of the supporting-stems or slides;
"Fig. 3 is aside elevation of the bevel square, the lateral blade being in section at its rear end; 1 i V 1 j Fig. 4 is a section on the line 4l-4 of FigureS. 1 a r Fig. 5 is a section on the line 55 of Fig-- :ure3;.
Y F ig. 6 is a section onthe line 66 of Figure.3. It'willbe seen that in general form the improved square is quite like the square illustrated in said'patent. The body of-ahe square'is designated 10 and may be made of a wood or other suitable material.
.edge face of the body is straight and the body is bifurcated almost in its entire length by a slot 11. Inserted in said slot is a blade 12 whose'inner end is longitudinally slotted as at 13 Theforwardend of the body 10 is reduced in thickness and passing through thisforwa'rd end is the bolt 14; carrying the wing nut 15. The slot 11 permits longitudinal adjustmentof the blade 12 and the bolt 14 permits a rotary adjustment of the blade; Thus, the blade can be set atany dcsired bevel. the blade is preferably inclined from its under edge to its upper or forward edge. Also The lower 2 The extreme forward end off blade is preferably formed with a" vertically disposed within the I slot 11 and extending r oFFIc of the body is reduced in depth so as to form a throat 17' and the forward end of the tongue 16 is'inclined upward and forward as at 18, this inclined end extendingup into thethro'at l7. This tongue 16 is held-in place by screws or other equivalentme'ans.
The side faces of the body 10 are channeled longitudinally for their entire length and disposed in each channel is a Chanel-shaped wear plate 20, see Figures 5 and 6. j At the throat 17 of the body, the lower flange of this channel-shaped wear plate is cut away as shownin Figure 4; Disposed in these channels are the longitudinally extending fiat stems 21 or shanks of supporting brackets 22 each at' itsforwa'rd end having an outstanding ear 23 apertured for the passage of a screw. These shanks 21 are held in sliding engagement within the channels 20 by longitudinally extending plates-24", each of which is held to the body by screws 25.
The plate 24: at its forward end is cut away 1 to provide av thr0at26 and the upper margin of this throat is graduated as at"27, each,
stem or shank 21 being provided with an indicating mark 28 which coacts" with these graduations to provide. a proper adjustment of the corresponding stem or shank; In orheaded pin 30' which extends transversely through the body 10, through the tongue 16, throughthe plates 24,-and through the bars 29, the heads of'this'pi'n' being *disposedin countersinks in the bars 29.
Passing through each bar. 29 and having screw-threaded engagement "therewith and with the plate 24: i's'a set screw '81 which when turned home, will engage the shank 21 and'hold it in its adjusted position."
P'votally, or slidably engaged with each ear 23 by meanslof a bolt32 and wing nut'33, is a blade 34,: each blade being longitudinally slotted as at 35 and the bolt 32 passing through this slot. The forward end of'eacli blade is angularly beveled with reference t0 the longitudinal axis ofthe blade so as'to providea pointed extremity 36 and each extendingfiange 3'7 and a horizontal flange '38 or, in other words, with an angular marin. As will be seen from Figure l,thehead 32 of the bolt 32 bears against the downwardly extending flange 37 and is thus held from rotation.
This "aids in clamping the blade-securely in its ad usted posltion' and at the same time the angular margin strengthensthe blade 34 and renders it more rigid and brings the marking edge ofthe blade in line with the lower edge of thebody :10. The blade 12 is preferably graduated in i the body. By providing thegraduationsQ'Y,
the slides or shanks 21 carrying the blades "34 maybe readily adjusted Without the necessity of using aisteel square andwthus the forward ends et the; blades 34 may be brought into any desired relation to the V blade 12 and. the point 36 ofjeach blade 34 may be-brought either into alignment with the forward edgeof the blade 12 or the rear edge thereof. The shanks 21 are guided throughout nearly their entire length by operating in the channels20 and, While freedom of movement is secured-for these shanks 21 when the jsetscrews 31 are released, yet the shanks are held from any up or downmovement, It is tobeparticularlynoted that the forward end of the body 10-is at right angles to the upper and lower edges of the body, Thislenables the blade 12 to be set .at'rightangles to the body without the use of a steel square.
One. of the faults of the construction i1- lustrated in the patent referredto was that the shank supporting the lateral blade would springwhen a pencil was. drawn along the outside of the angular blade. This is entirelyprevented' with m improved construction forthe reason that the shank issupv-portedalong itsentire lengthand is engaged over nearly i-ts' entireextent by the platejQL,
