Application filed August l8, 1919. Serial No. 318,348.

To all whom r125 may concern:

Be it known that T, Cries. ESSELSTYKE, a citizen of the United States, residing at 1.396 Mciiillister Streehcity and county of San Francisco, and State of California, have invented a new and useful tool used by printers and known as a Composing-Stick Knee. 1

My invention relates to improvements in composing sticks, in that my device secures an absolutely rigid and accurate knee, which may be adjusted to a hair, by a micrometer attachment which I have originated and em bodied in my invention as an integral part thereof.

Figure 1 is a view in perspective showing the present invention.

Fig. 2 is a view in end elevation showing the knee member. I

Fig. 8 is a fragmentary view in section showing the adjustable mechanism of the knee.

Similar letters refer to similar parts throughout the several views.

The knee, designated in Figures 2 and 3, is applied to the panby inserting; the heel or rear end of the pan into the slot, 9', and sliding along until the knee reaches the point desired. This sets or adjusts the knee to even picas (printers measure). Should the adjustment desired he an uneven, or what is technically known as bastard measure. the screw, 0, (Figs. 2 and 4) is turned by its milled head, either forward or backward as the case requires, until the knee rests at the desired point, when the thumb screw, Z), is turned to the right until tight, when the knee is securely locked and the stick is then ready for use.

The micromatio adjustment is secured by the bar, '5, (Figs. 3 and t) engaging the holes (which may be round or square) in the hottom or turned up edge or flange of the pan by the sprockets or lugs, g, of which there may be one or more, in this case four. This bar slides forward and backward in a slot or groove cut in the under edge of the knee proper, is, guided bypins, (Z, (Flg. 2), which are entered in slots at each end of bar and marked 72 (Figs. 3 and 4:). These pins, (Z, also act as stops and allow the bar to travel about one-fourth of an inch forward and backward. The movement of the bar is attained by the screw, 0, (Figs. 2 and 4) which is seated in the rear end of the knee. This screw, the thread (Z) ofwhich engages a like thread cut in the upper corner i v or the rear end of the bar, (1 1g. 4-) and I rotating to the right or left causes thebar to move forward or backward thus securing a micromatic adjustment of the knee.

As previously mentioned, a pica, one-sixth of an inch, a standard printers measurement. Apica isdivided intov twelve parts called points; consequently a point is one seventy-second part of an inch. The-thread on this screw, c,andthis bar, f, is thirty-sin to the inch. Therefore one full turn of the screw slides the bar two pointsyone half turn, one point; and one-quarter, turmerichalf point, etc. Thisis indicated by markings or scores upon the screw head adjoining part of the knee. F allayed by the hanging of the screw by the collar 0 and small pin, 6. i The small collar 0 on the screw attaches to the knee proper by a small pin which cannot be shown. The

pin or gudgeonon the end of the screw tits into a bearing in the knee above the top edge 'ing the edge or flange of the pan to the bottom of bar and to the knee, and the top edge of pan to the top of the slot in the ee,

The slide is is approximately, L-shaped to receive the pan. and flange thereof and the flange receiving portion of the slot is enlarged to permit a relative laterally tilted movement of the knee and the flange.

I claim:

1. A composing stick comprising a pan member having'a longitudinally extending flange along one marginal edge thereof, a knee slidable along said flange and extend ing across the'pan, primary locking means for securing the knee in approximate adj ustment relative to the pan, and secondary means including a micrometer screw eon nectedwith the primary lookingmeans and the knee for accurately adjusting the knee without unlocking thesaid primary locking 2. A composingv stick comprising a pan memberhaving a verticalstop at one end i other, a composing stick knee slidably locking means for securing said knee in approximate adjustment with relation to desired stops along the longitudinal flange of the pan, and a secondary adjusting means connected with the primary locking means and with the knee and including a microme ter scre for moving the knee after it been set relative to the flange.

3. it composing stick comprising a pan having ledge across one end thereof and a long idinal flange along one edge thereof, coniposin stick kneeslidahly mounted on said in for longitudinal movement, prim 7 locking means cooperating hetwe n the longitudinal flange and the knee, for lockin said knee approximate adjustment with relation thereto, and whereby a tilting movement of the knee relative to the flange will permit it to be released and moved, and a secondary locking means including a micromet-er screw connecting the primary looking means with the in ce for GllGClZli adjustment of the knee Without unlocking the said primary locking means.

a. A composing stick comprising a pan having a ledge across one end thereof and a longitudinal flange along one edge thereof, a composing stick knee slidably mounted upon said pan for longitudinal movement, prii'nary locking means cooperating between the longitudinal flange and the knee, for locking said knee intoproximate adjust- .l ment with relation thereto, and whereby tilting movement of the knee relative to the flange will permit it to be released and moved, and secondary locking means for ac justing said knee relative to the pan after it has been approximately set, said secondary locking means including a micrometer screw connecting the primary locking means with the knee and adapted to move the latter without unlocking the former.

5. A composing stick comprising a pan member having a ledge at one end thereof and a marginal flange along one edge thereof, said flange being formed with a plurality of equally spaced perforations throughout its length, a composing stick knee slidable longitudinally of the pan, a slide thereon having projecting means for engaging perforations of the flange to approximately set the knee, and a micrometer screw connecting the slide with the knee for adjusting the knee Without disengaging the slide from the said flange.

6. In combination with a composing stick and the flange receiv having a longitudinal thereon, said flange being formed with a series of equally spaced composing stick knee-consisting of arms at 1 angles to each other, one arm extending across the stick and the other arm coinciding with the face of the flange, said knee being provided with an approximately i.- shaped slot to receive the stick and the flange, portion of the slot nt a relative lateral being enlarged to pern movement of the knee, and the flangemeans cking the knee to the flange byations thereof,

normallv o t. 1 n withthe pc and whereby the tilting action of. the knee will release said knocking means, and means for clamping the knee in its locked position.

7. in combination with a composing stick lon I tndinal flange thereon, said being iormed witha series of equally spaced perforations ti roughout its lengtlna composing stick knee consisting of arms at right angles to each other, one arm extending across the stick and the other one coinciding with the face of the flange, means for slidably mounting said knee upon the stick and for permitting it to have a tilting movement relative to the face of the flange, primary locking means normally securing the knee to the flange in approximate adjustment by engagment with the perforations thereo" and whereby the tilting action of the knee will release said lock means, and means for clamping the knee in its locked. position, and means embodied within the leg. of the knee and including a micrometer screw extending along the flange to accurately adjust the knee after it. has been locked without unfastening the primary locking means.

8. A composing stick knee comprising a pair of arms at right angles to eachothe'r, one of which extends across the face of the composing stick and the other along the longitudinal fiange thereon, guide means for Witnesses:
