UNITED STATES PATENT onirica.
EARA E. BATHRW, OFPRINCE ALBERT, SASKATCHEWAN, CANADA.
l SQUARE Specincation of Letters Patent.
Patented Dec. 24, 1907.
Application tiled March 10. 1906. Serial No. 305,373.
Be it known that T, Ezim E. Bri'iiinow, a
subject oi" the Kino of England, residing at .lrince Albert, Sas ratchewan, North est Territory, Dominion of Canada, have in-I vented a new and usetul Square, ot which .the following is a speciiication.
acter in which the blades may be folded into i parallel relations when not in use, and extended and autoniatically held in extended position when required. l
W th these and other objects in view which will appear as the nature oi the invention is a better understood, the invention consists in certain novel fea-tures of construction as hereafter fully described and claimed.
ln the accompanying drawings forming a part of this specification and in `which corresponding parts are denoted by like designating characters, is illustrated the preferred forni of the embodiment of the inventief` capable of carrying the. same into practical operation. j
In the-drawiiigs-Figure 1 is a side view of a portion ofthe improved device including` j the elbow and portions'ol1 the blades, from Fig. 2 is a similar view from the i o iiosite side. Fios. 3 and 4 are iers ective views of the two portions of the blades, dis- 7 connected. Fig. 5 is a detail edge view o1" the joint between thi` blades.
The improved device is more' particularly applicable to the ordinary -iarpenteis7 square consisting of one relatively' long and wide blade called the bladc'f, and one relatively narrow and shorterblade called the tongue. the two members being suitably into inches and parts of inches graduations.
The blade is generally twenty four inches long and the tongue l'roin twelve. to sixteen inches long.
The blade 10 in the improved device is provided with a .projection 11 yne half the thickness of the blade and extending' i the direction oi the tongue 12. while thi` inner portion of the tongue ,is cut away to form the plate. 13 one half its thickness and overlapping the project-ion 11 ofthe blade.
The l'.erlapping portions are united by a pivot 14, with the free end of the projection 11 curved at 15 concentric to the pivot, and
grailuated"I and other l the shoulder l'fornied between the body of i the tongue 12, and the plate 13 correspondingly curved as shown. f
T he free curved end 17 of the plate 13 engages'the shoulder 18 formed between the projection 11 and the blade 10.
The projection 11 is provided with a lug 19 adapted to tit into a socket or recess20 inthe ttongue 12, while the plate portion 13 yisprovided with a similar lug 21 for engaging a socket or cavity 22 in the blade 1Q, r.the lugs faces, and with square shoulders 23e-24g at the roots of the` lugs, for bea-rin' T against' the eorresponi'lingly formed ends o the respecl tive lugs ,which engage them. A The lugs 19 and 21 thus forni stops to prevent the tongue 12 lfrom swinging'beyond a l position square with the blade'10, while the 4' inclined faces of the lugs engaging the cor- L respondingly inclined faces of the recesses, l forni an eil'ectual locking means against lateral movement between the parts.
The shoulder 23 and 24 add materially to l the stability of the joint, by bearing a large 5 share of the friction and. relieving the relatively thin terminals of the lugs from'a corresponding portion oi" the strain` The projection 11 is formed with a recess 25 linto which the point 26 of the shoulder portion 16 oi the tongue 12 enters when the blades are placed in parallel positions, as indicated by dotted lines in Fig. 1
Formed. through the blade 10 adjacent to the recess 22 is a slot 27 in which a spring 28 is secured by a screw pin 29, the terminal ot the spring operating` in a recess 30 eX- tending entirely through the blade, the blade also having a thumb recess er depression 31 to enable the operator to manipu-.
,i late the spring.
The plate 125 is provided with a recess 32 which comes opposite the recess 30 in the lblade 1() when the blade and tongue are iig) operative position, as in Fig. 1, with' the vinner end im i at a less angle than the sweep of the spring 2S, so that as the latter attempts to move away from its recess 30, it will impart a stronfgI pressure against the inclined face 3S and iirmly lock the two members 10 and i 12 in their right angled position. The spring thus imparts a cit-nstant strain upon the plate 13, and any wear which may occur bet'iveen the two parts, is taken up by the constfiit i pressure of the spring. Thus all tendencyr to and recess being inclined at theirengaging l i `the rceess 32 inclined -what is claimed is 1. In an implement of the class described, the blade portion having a projection extending at right angles therefrom andof less thickness than the same and with a lug extending from its free end and a recess in the blade at the inner end ,of the projection, the tongue portion having a plate at one end less in thickness than the tongue and overlapping said projection and pivotally united thereto, said plate. having l a vlug for bearing within the recess of said l blade and said tongue having a recess for receiving the lug of said projection, and; means for locking said projection and plate in position.
2. In an implement of the class described, the blade portion having a projection at one end with a lug extending therefrom and! inclined at one side and a recess in thei blade formed with one inclined side, a tongue i portionhaving a plate at one end overlapping said projection and pivotally united.;
thereto, said plate having a'lugvfor bearing within the recess of said blade and inclined t to correspond therewith and said tongue having a recess for receiving the lug of said projection and inclined to correspond thereto, and means for locking said projection and plate in position.
In an implement of the class described, the blade portion having a projection at one end, the tongue portion having a plate at one end overlapping said projection and pivoted thereto and with a recess having an inclined end, and a spring carried by said blade and disposed with its free end bearing against the inclined end of said recess.
4. In an implement of the class described, the blade portion having a projection at one end and an aperture partly in the blade and partly in the projection and a slot ex- 55 tending Ifrom the aperture, the tongue portion having a plate at one end overlapping said projection and pivoted thereto and with a recess having an inclined end, and a spring secured in said slot and bearing at its free end against the inclined end of said recess. ln testiinonv that I claim the foregoing as my own, -ave hereto allixed my signature in the presence of two'witnesses.
EZHA' it. BATHROW. Witnesses: I GRAHAM NnrLsoN, Geenen Wim.
