Description
A. 'TURGEON- SQUARE.
APPLICATION FILED AUG.13, 1913.
Patented Jan. 19, 1915.
mmron T u r gs o n HIS A TTORNEY M WW V ARTHUR runenoiror .srnnnrcnn, MAINE.
f SQUARE.
1,1aarm;
To all whom it may concern r Be it known that I, ARTHUR TURGEON, a citizen of the United States, residing at Biddeford, in the county of York and State of Maine, have invented certain new and useful Improvements in Squares, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention relates to a square and has for its object the production of a simple and efficient device for measuring surfaces and also for determiningwhether or not a surface is level or uneven.
Another object of this invention is the production of a square which is provided with a brace for reducing the strain, of holding the square in an extended position, from the pivot member. 7
With these and other objects in view, this invention consists of certain novel combinations, constructions and arrangements of parts as will be hereinafter fully described and claimed.
In the accompanying drawing: Figure 1 is a front elevation of the square showing a portion of the same partly in section. Fig. 2 is an elevation of the rear portion of the square. Fig. 3 is a section taken on the line 33 of Fig. 2. Fig. 1 is a section taken on the line 4& of Fig. 1. Fig. 5 is a perspective view of the bracing member.
Referring to the accompanying drawing by numerals it will be seen that the square comprises a primary section 1, which is provided at its inner end with a flat head 2. The auxiliary section 3 is provided with a V rounded head 4; and these heads 2 and 4: are
provided with the registering openings 5 for receiving the pivot pin 6. This pivot pin 6 is provided with a threaded end for carrying the wing nut 7 whereby the wing nut may be threaded upon this pin 6 for binding the sections in an open or closed posi tion. I
The primary section 1 is provided witlra spirit level 8 for measuring plane surfaces and also provided with a spirit level 9 for determining the evenness of a vertical wall, or similar structure. A groove 10 is formed longitudinally in the primary section 1 for carrying the graduated arm 11. Thls arm is slidably mounted within the groove 10 so as to allow the same to be easily withdrawn, if so desired. The outer end of this armll is provided with an integral transverse head.
- Specification of Letters Patent. Application filed August 13, 1913. Serial 110.784322.
Patented Jan. is, 1915.
12 having a beveled corner 13 By withdrawing this arm 11 for a distance beyond the end of the primary sectionl a person can very easily'obtain a device which answers the requirements of an L-square. The head 4 is provided with a graduated disk 14, this disk 14 being held in position by means of the rivets 15. In this manner it will be seen that by moving the two sections apart, so as to allow the same to swing upon the pin 6, any desired angle maybe lndicated by the intersection of the inner longitudinal edge of the auxiliary section 3 with one of the lines formed upon the disk 14:. In order to relieve a considerable strain from the pin 6 and the wing nut 7 there is provided a bracing member. This bracing member is formed from a blank strip of material and comprises a pair of fingers 16 which are connected to each other by means of the angularly extending bridge 17. These fingers are provided at their outer ends with the bodies 18 in which there are formed the apertures 19. This bracing member is fixedly secured to the rear side of the auxiliary section 3 by means of a screw or rivet 20. One of the fingers 16 will rest snugly upon this auxiliary section 3 while the other finger 16 will rest upon the head 2 of the primary section 1. The bridge 17 will rest upon the edge of the head 2 so as to allow the bracing member to rest snugly upon the two sections throughout its entire length, as clearly illustrated in Fig. 3. The pivot pin 6 passes through the other body 18 so as to be brought into a binding engagement with the head 2 by tightening the wing nut 7 upon the oif-set pin 6. In this manner it will be seen that the outer end portion of the bracing member through which the screw 20 passes will be positioned at a spaced distance from the pivot pin, thereby producing sufficient leverage to allow the same to efliciently brace the two sections for holding the sections in a set position when the nut has been tightened upon the pivot pin.
From the foregoing description it will be seen that an efficient combination square and level has been produced which is provided with an eiiicient bracing member for holding the sections in an open or closed position, and in this manner relieve the pivot pin of a considerable strain.
Having thus described the invention, what is claimed as new, is:
A square comprising a primary and an auxiliary section, said sections provided with rounded heads, a pivot pin passing through said heads, a nut threaded upon a said pin whereby said heads may be held 7 together for holding said sections in a set .tire length, an integral bridge formed upon the inner ends of said .fingers and extending at right angles to said Ifin- :gers, means for holding one :finger of said bracing member upon said auxiliary section, the other finger resting upon the vhead .of
, said primary section, said last-mentioned finger adapted to be held in binding engagement'with said head by means of said pivot pin and nut, said bridge bearing upon the edge of the head'of said primary section, whereby the oil-set fixedly secured outer end a spaced distance from said pivot pin, said bracing member fitting snugly upon said primary sections throughout its entire length thereby producing a firm binding action for assisting in holding the section in a set position.
In testimony whereof I hereunto affix my signature in presence of two Witnesses.
