Application 1ed February 17, 1910. Serial No. 544,475. v

To all whomit may concern:

Be it known that I, GnonenM. DURELL, a

citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented a new and useful lmprovement in Self-Locking and Point-Setting Composing-Sticks, of which the following is a specification.

My invention relates to a composing stick and has for its object to provide a convenient and accurate device of the kind that is readily adjustable for setting lines of type of any desired nonpareil, pica or point length, and that is self locking when adjusted for any length of line. I accomplish these objects by the construction and combination of parts, as hereinafter described and illustrated in the drawings, in which- Figure 1 is a view in perspective of a composing stick constructed in accordance with my invention, with the knee in positionand locked thereo-n. Fig. 2 is a side elevation of the same partly broken away, and showing the knee in position either for adjustment, attachment, or detachment. Fig. 3 is a top view of the same, sectioned on line az-m of Fig. 4, and showing a portion of the top of the knee block broken away. Fig. 4 is a cross section of the stick on line g/-y of Fig. 3.

In the drawings 1 designates the body of a composing stick, formed preferably of sheet metal, and comprising the graduated receiving base 2 of suitable width and length, and having a straight edge 3; a back wall 4 at right angles to the base, and parallel with the straight edge 3, and having its top edge provided with ratchet teeth; the end wall 5, at right angles to the base, the back wall, and the straight edge, and having an end portion 6 projecting beyond the line of the' straight edge forming a hook adapting the base for line measurement; and the adjustable knee 7.

The knee 7 comprises the rectangular L shaped block 8, having its bottom 9 faced to engage and rest on the base 2, the side wall 10 faced to closely engage the back wall 4, the end wall 11 faced at right angles to the bottom 9 and the side wall 10, the side 12 provided with a lengthwise groove 13, and the top 14 having the recessed portion 15 and the lengthwise groove 16 adjacent to the side wall 10; the helical spring 17 in the groove 13; the push bar 18 movable along the side 12 and in the groove 13 and engaging one end of the spring; the ratchet bar 19 ad justably mounted in the groove 16; and the movable locking plate 2O havint a side 21. bent downward at right angles rom a central portion 22 parallel with the side wall 10, and a side 23 bent downward from the central portion 22, but diverging at an angle from the side 12 toward the wall 11, the central portion 22 being provided with a rectanguiar opening 24 above the recess 15 of the block S and extending to the side 21.

The ratchet bar 19 has a central top portion 25 of increased width which extends outward over the back wall 4, and central through the portion 25 of the bar 19 is provided a short slot 26, which extends lengthwise of the bar.l Below the slot the block 8 is tapped to receive a set screw 27, which eX- tends through Vthe slot into the block, and when partly run into the block allows limited lengthwise movement of the ratchet bar, and when run in until the head of the screw is shouldered against the bar, locks it againstmovement. The under side of the margin of the central portion 25 of the ratchet bar 19 has ratchet teeth formed thereon complementary to the teeth of the i any point, the teeth ofthe ratchet bar iit into the incuts forming the adjacent teeth of the back wall 5.

The locking plate 20 is provided with the slightly elongated holes 29 to receive the stud screws 30 which are tapped. into the block S and movably secure the plate to the block, the elongations of the holes 29 beingadapted to permit limited movement o f the plate transverse the block S.-

The push bar 18 on its outer face is provided with an incline face 31, complementary to the inclined inner face of the side 23 of the locking plate 20, and when the plate is mounted on thc block 8 with the side 23 engaging the incline face 31 of the push bar, the spring normally holds the push bar to the limit of its outward movement, whereby the plate is moved to bring the side 21 of the plate toward the side 10 of the block 8, and when the bar 1S is pushed inward, compressing the spring, the incline face of the push bar is disengaged from the side 23 of the plate,-

the ratchet bar 19 is provided a point index 32 which is pivoted on the stud screw 3() by one end, and extends therefrom toward the face 1l ot' the block 8. The index 32 has a short arm 33 extending at right angles` to the pivotal bearing ot' the index and into a notch 3 4 of `the ratchet bar l2) whereby when the 'ratchet bar or the block 8 is moved T relatively to the other, in one direction, the

point of the index is moved outward from the barl9 through an arc, over the graduations o11;the,-recessed face. ofithe block, and. when relatively moved inthe opposite direction thegpoint ot'l the index isanoved over the graduations35itoward4-the bar. 19. rlhe distance,of relative movement of the ratchet bar 19 and the. block, 8 is eqnali to the measured :linespace ot' a nonpareil em, and ,the graduations `35 indicate1 the points into which av-nonpareil space is divided Saccording to theipoint. system otr type line measurement@v ffc: if i 1,Millie,teetlrot' the back wall 4 have a shoulderglfacel perpendicular tothe base 2r-and facedtoward the end; wa'll y5, and the distance between the perpendicular faces lotl thefteethfisiequalz toa nonpareil em.

@The perpencliculartaces of theteeth ofthe ratehetbar are facedoppositefrom the face lllotf-the block 8 and the distance between the ,perpendicular faces of the teeth ofthe ratchetibar being alsoi equal to a nonpareil em-Whenthe teeth ofthe ratchet bar are in engagement Vwith the teeth of the back wall, the perpeiidiculaitaces of the teeth of the ratchet baneoincide witlrand abut the perpendicular faces of corresponding' teeth of the back `wall,:whereby the knee 7 is held at any4 position it is. placed against the back wall agaifnstinovement in. the direction away from the,end wall 4The perpendicular faces of the teeth of the back wall are also incross',alfinementlwith theI lines forming the nonpareildivisions of the graduated sca-le of the base 2.

ggflhus constructed, the operation of setting thejgknee 7 toi any desired lengthof line is as follows:Holdingythe stiekililin his lett hand with t-he back wall uppermost and the knee Flin theright hand wit-h the-top lplate uppermost beneath thegtpalm,l with the tingers against the falce l1 and the thumb pressing ,againstth e push bar until thezflocking face isiloosened and free to move, the yoperator, pushes the. knee downwardon the stick with theback wall between .the side 2l ot' theloeking. plate,4 `and the side lOofithe bloclgand,with the face ll alined with the graduation .on the scale designating the length of line in `nonpareil ems desired. Yhenfthe bottom sideof the knee restsV on thelbase 2, .onreleasing the push bar, the spring movesit outward and the incline 3l ofthebarengaging the side 23 of the locking plate wedges between the side 23 and the I block S and moves the plate until the side 2l ot' the plate and the side l0 of the block are engaged with and pressed oppositely against the back wall 4. The outer angle at ot' the back wall 4 with the base 2 is slightly rounded, and the side 23 is slightly curved inward along its free edge 21, whereby when the side 2l is moved into engagement- .with the back wall by the push bar, the

gages the rounded corner 4 of the back wall, and locks the knee against bei-'ng lifted from the base 2, and the teeth ofthe ratchet bar together-.with the edge -portioni23 locks it against being moved lengthwise of the back-wall in eitherdirection.

It it is desired to -move the knee from any position on the base 2 Vto apositionfarther away from the end wall 5,"t'he' knee is, grasped as before described andfwhen the push bar hasbeen push'edin vby thethumb and: the lockingl 'plate released' the knee is tilted by thei thumb engaging -the push bar onzthe lower corner formedby the face ll with the bottom side ofthe block 8,l in which Iposition the teethiof the ratchet barbeing disengaged from the teeth ot the backwall 5, the'knee may be mo'vedalong "the back wall until-theflower edge ot' the tace-"ll coincides with-the desired'graduating line `of the base 2.- The raised end of thekneebeing thenpushed down on thebase2 andthe push bar-released, the knee is again automatically loeked-inits new position. lf itis desired to move the knee=toward the end wall `5 from Vany position, after thel lock plate has been released byi pressure of the thumb on the push bar the knee'may be -movedllalongl the back wall andibase:withoutf'tilting the knee, and upon releasing hold of the=knee the action ofthe spring on the push bar will again automaticallylock the -knee in" its new position. Should -fit be desired to l lengthen the `line thus established o'n'e'or more'points less thanialnonpariel em, the set screw 27 of the ratchet bar-` isf run outward sutticientlyV to unlock 'the bar and `pres'sureis applied on the `face ll of blockS tomo've it relatively 'to' the ratchet bar unt-il theindex point 32 has (by reason of its1 pivotal bearing beingmoved relatively to the notch 34 ot'.- the ratchet bar) ,l been moved over'the graduations 35 the desired number ofpoints. The bar being then locked by the set screw the knee is firmly established on theJ base 2 for the line desired. vIt is apparent that this adjustment for points greater vor less -th'an any number of nonpariel units of 4measurement may be made when the knee 7-is'd`etached from the stick, by movement ofthe ratchet bar relative to the block S untily the index shows the desired number of points of variation and then locking the bar by theV setscrew 27, and when thus adjusted, whereever attached to the back wall et, the point curved edge portion 2l of the side 23 enf `variation of the knee from the scale of the not limit. myself to placing such graduationsl on the base. It is further manifest that the teeth of the back wall, the ratchet bar, thepoint index, and the graduations pf the base and knee, all being omitted', the knee may Hstill be convenientlyA adjusted on the base `and automatically locked on the back wall fora desired length of line, by adjusting the knee on the base to a slug of a line of that length.

of those elements in combination with a self locking knee. l

What I claim to b e new is-n 1. The combination with the base, back w'all, and end wall of a composing stick, of a knee comprising a rectangular block member faced to abut the back Wall and rest on the base, a clamping member movably mounted on the block and adapted to engage the back wall oppositely to the block, when the block is mounted on the base abutting the back wall, and locking means adapted to automatically press the block and the clamping member oppositely on the back wall, when the knee is manually so mounted on the base and released, and that is adapted to release the clamping member by manual pressure on the locking means and the knee.

2. The combination with the base and back wall of a composing stick, of a knee adapted to be mounted on the base abutting the back wall, a clamp movably mounted on v the knee and adapted to clamp the knee to the back wall when the knee is in position on the base abuttingl the back wall, and means engaging the clamp and the knee comprising a push bar and a spring, adapted to automatically press the knee and the clamp oppositely on the back Wall, and lock the knee thereto when the knee is manually placed thereon and released as set forth, and to unlock the knee by moving the push bar to compress the spring while manually lifting the knee from the base.

3. The combination with the base and back wall of a composing stick, of a knee adapted to be mounted on the base abutting the back wall, a clamp mounted on the knee and movable thereon from the abutting face of the knee, to receive the back wall therebetween, and toward the knee to engage the back wall and clamp the knee thereto, and

I therefore do not limit myself in` 4the construction of my invention to the use locking means comprising a push bar and 'a spring, operating, when the push bar is pressed against the spring in manually placing the knee on the base, to permit the clamp to openv from the knee to receive the back Wall between 'the' knee and the clamp, and when the knee is resting on the base -abutting the back wall and manually released, to automatically press the knee and the clamp oppositely on the back wall and lock the knee thereto.

4. The combination with the base and back wall of a composing stick of a knee adapted to be mounted on the base, and automatically clamped to the back wall, said knee comprising a rectangular block having parallel side faces, one adapted to abut the back Wall and the other provided with a groove, a helical spring in the groove, a push bar movable along the grooved face of the block and engaging one end of the spring, said push bar having an outer face inclined to its inner face, a clamping plate mountedand movably secured transverse the block, said plate having side portions angled, one parallel with the back wall abut ting face, and spaced therefrom to receive the back wall therebetween, and the other parallel with the inclined face of the push bar, whereby the expansion of the spring automatically wedges the push bar between the block and the inclined side portion of the plate, and clamps the block and plate on the back wall, and the compression of the spring by the push bar releases the pressure of the push bar on the block and the plate and leaves the/knee free to be lifted from the base.

5. In a composing stick, the combination with a base, end wall, and a back wall having its top edge uniformly serrated, with the points of the teeth at intervals equal to a nonpareil em, of a knee adapted to be mounted on the base abutting any portion of the back wall, a ratchet bar mounted on the knee and relatively adjustable thereon by a movement of the bar or the knee, and having a portion extending laterally over the back wall, said portion being provided with teeth complementary to and engaging the teeth of the back wall when the knee abuts the back Wall, a point index pivotally mounted on and movable over the upper face of the knee and adapt-ed to be moved on its pivot through an arc by any movement of the ratchet bar or the knee relative to the other of them, index lines on the knee dividing the arc of movement of the point of the index and indicating point distance of movement of the ratchet bar or the knee relative to the other of them.
