CLARENCE FRANKLIN BENJAMIN, 0F MILFORD. CONNECTICUT.
COMBINED CARPENTERS SQUARE AND'MITER GAGE.
To aZZ whom it may concern:
Be it known that I, CLARENCE F. BENJA- MIN, a citizen of the United States, residing at the town of Milford, county of New Haven, State of Connecticut, have invented certain new and useful Improvements in Combined Carpenters Squares and Miter- (lages; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to certain new and useful improvements in combined carpenters square and miter gage, and more particularlyto improvements on the construction shown and described in Letters Patent No. 1,158,775, issued to me November 2,
In my prior construction, I provided notches on the periphery of one of the members and the interlocking device on the inside edge of the other member. The notches were exposed to clogging foreign matter, and the particular form and design of square often rendered it difficult, if not impossible to mark offa continuous angular line.
The primary aim of the invention, therefore, is toentirely eliminate these disadvantages from a combined square and miter gage.
Another object is to provide an improved instrument of the character described which may easily, quickly and efficiently be set for different angles.
The invention further resides in an improved locking means for the blades of the square, and also in the features of construction clearly described in the following specification and succinctly defined in the Specification of Letters Patent.
Patented iltay 15, 1917.
Application filed Aprill'Y, 1916. Serial No. 91,532.
ployed to keep the teeth seated in the notches; r
Fig. 6 is a fragmentary longitudinal section of the instrument showing the locking means; and
Fig. 7 is a detailed view of a modified form of lock.
The type of instrument shown embodies three sections, and while I have shown the present invention disposed only between the central body A. and blade 2, it is obvious that the same locking mechanism may be employed to connect the body with blade 8.
The central body section consists of a pair of plates 4 and i sustained apart at one end; by the hub 5 of blade 3 and at the opposite end by a sleeve 6 through which a screw 7 passes, the head of the screw being countersunk in the plate 4 and the threaded end anchored in plate l to hold the plates relatively fixed (Fig. 6).
a The blade section 9. freely engages about the sleeve 6 for both pivoted and closing movement between the body plates 4 and 41. The inner face of body plate 4: is'provided with an annular series of recesses or notches 8 arranged concentrically about and spaced radially from the sleeve 6. In these notches 8 is adapted to engage the circular series of teeth 9 formed on the opposing part of blade 2, a star-likespring 10 being slidable on sleeve 6 and interposed between the blade and plate 4 to maintain the teeth normally engaged in the notches. The radial terminals of the spring are bowed and bear on the body plate to exert even pressure on the blade 2.
Sufficient space between the body plates is provided to permit of the necessary closing movement of the blade on the sleeve 6 whereby the teeth will be entirely disengaged from the notches and the blade will be free for adjustment to the desired angular relation with the body.
To effect easily the swinging of the blade on the sleeve, I provide a button 11 with spaced pins 12 slidable through suitable openings 0; formed in plate 4. The projecting ends of thepins are headed, as at 13, and adapted to engage the blade 2 at pointson each side of the sleeve. The openings in plate 4 are provided within the inner circumference of the series of notches 8 so that the pins will engage inwardly from the annular path which the teeth traverse. Thus, by exerting inward pressure on the button 11, the teeth will be disengaged from the notches and the pins will not obstruct the passage of the teeth as the blade is moved to its new position.
In this type of tool, the constant wear between the blade and body at their pivotal connection will produce a loose joint and to accommodate for this wear the apices of the teeth are flattened, as at 14:, so that as the wear occurs, the teeth will always have a firm seating being urged into the notches by spring 10.
In Fig. 7 is depicted a modified form of pivotal connection and locking means, the same comprising a winged screw 15 having swiveled connection with the body plate 4: and blade 2 and threadedly engagel with the plate 4: to advance or retract the teeth from their notches. A. spacing Washer 16 may be interposed between the body plate 4 and the blade-2 to prevent the latter from moving over against the blade 8.
It is apparent, therefore, that quick adjustment may easily be obtained by simply,
pressing in on the button 11 and swinging the blade to the desired angle after which the button is released to seat the teeth in the newly presented notches. The latter are covered and protected from foreign matter, and the flattened apices of the teeth always afford a good wedging in the notches.
"What is claimed is:
1. In an instrument of the character described, a body consisting of spaced plates and a sleeve interposed therebetween, a blade disposed loosely on the sleeve between the body plates for swinging movements, a circular series of teeth provided on the blade about the sleeve, the opposing face of the adjacent body plate being provided with a like series of notches to receive the teeth, a button having spaced pins slidable through the body plate specified and adapted to engage the blade at points within the circular series of teeth, and a bowed spring interposed between the other body plate and the blade tohold normally the teeth in engagement with the body notches.
2. In an instrument of the character described, a body consisting of spaced plates and a sleeve interposed therebetween, a blade disposed loosely on the sleeve between the body plates for swinging movements, a circular series of teeth provided on the blade about the sleeve, the opposing face of the adjacent body plate being provided with a like series of notches to receive the teeth, a button having spaced pins slidable through the body plate specified and adapted to engage the blade at points within the circular series of teeth, and a spring interposed between the other body plate and the blade, the apices of the teeth being flattened.
3. In an instrument of the character described, a body plate having an annular se ries of notches on one face and an opening within the series, a blade having pivotal connection with the body plate, a tooth on the blade adapted for meshing with the notches, resilient means normally holding the tooth in mesh with a notch, and means operable through the opening of the body plate for engaging with the blade to unseat the tooth from the notch.
4. In an instrument of the character described, a-pair of spaced plates one of which is provided on its inner face with an annular series of notches, a pivoted toothed blade between said plates, and a rotatable screw threadedly engagingthe notched plate while the other plate and the blade are freely pivoted around said screw, whereby the operation of the latter'will effect the engagement and disengagement of the toothed blade and notched plate.
5. In an instrument of the scharacter described, a body plate, a pivot pin therefor, said plate having a notch, a blade pivoted on the pin and having a tooth adapted to engage in the plate notch, said tooth being spaced radially from the pivot pin, and means engaging the blade between the path of the tooth and the pivot pin for disengaging the tooth from the plate notch.
6. In an instrument of the character described, a body plate,'a pivot pin therefor, said plate having a notch, a blade pivoted on the pin and having a tooth adapted to engage in the plate notch, said tooth being spaced radially from the pivot pin, spring means normally holding the tooth engaged in the notch of the plate, and means engaging the blade between the path of the tooth and the pivot pin for disengaging the tooth from the plate notch.
. 7. In an instrument of the character dc scribed, a body plate having a circular series of notched and spaced openings within the series, a button having spaced pins CLARENCE FRANKLIN BENJAMIN.
