A'rENr SELF-LOCKING FRAME.

Application filed July 24,1922. Serial No. 577,125. 7 A

T 0 aZZ to item it may concern:

Be it known that I, WILLIAM B. REN- Nnn, a citizen of Germany, residing at Eidgewood, in the county of Queens and State of New York, have invented new and useful Improvements in Self-Locking Frames, of which the following is a specifloat-ion.

This invention relates to self locking frames.

More particularly the invention relates to type holding frames or chases. 7

Some of the objects of the present invention are: to produce a device of the character mentioned with which a job may be readily set-up, and no matter how intricate the type composition may be or how often the type are removed and replaced in making corrections, changes, overruns, etc.; to produce a comparatively simple and practical device of thecharacter mentioned which is convenient in use and which obviates the use of a string or the like; to produce a type frame in which the job may be maintained in set-up condition from the time it is made up until it is printed; and with these and other objects in view the invention resides in the particular provision, formation and functions of the parts hereinafter fully described and illustrated in the accompanying drawing, in which Figure 1 is a perspective view of the frame of the present invention, and illustrating conventionally the type composition.

Figure 2 is a perspective view of one of the bars of the frame.

' Figure 3 is a perspective view of another one of the bars of the frame.

Figure 4: is a detail sectional view taken on the line 1 1 of Figure 1.

Figure 5 is a detail sectional View taken on the line 55 of Figure 1.

The type frame of the present invention will be made of any standard sizes in accordance with typographical measurements.

The frame comprises bars in pairs of predetermined lengths; the bars of each pair being identical. In the present invention, the frame 10 is rectan ular in shape and is made up of a pair of bars 11 and a pair of bars 12. In reality the bars 11 are side bars and the bars 12 are end bars. Inasmuch as the bars of each pair are identical a description of one will suflice for both, and one of which bars 12 is presently described. The bar 12 at each end thereof is formed with an angularly disposed part 13', the

same being disposed at a right angle with respect to the main part ofthe bar. The cross-sectional area of the part 13 is substantially one-half of the cross sectional .area of the main part of the b'ar 12.

recess 14 is also formed at each end of the bar in the main part ofthe bar whichleaves,

a portion 15 at each end of the main part of the bar 12. Inasmuch ,as the part1? in cross-sectional area is substantially one-half .the cross-sectional areaof the bar there will be provided a recess 14; at each end of the bar.

Inasmuch as the bars ll are identical a one-half of the cross-sectional area of the the portions 19 of the bars 11 disposed. in'

the recesses 16 of the bars 12; and the portion 15 of the bars 12 disposed contiguous the parts 17 and the bars 11. It will now be manifest that bars 11 and 12 when brought together form a rectangular frame as shown in Figure 1, and defines a space for the type which when arranged within the space is effectively held by the bars from the time the composition is complete 'or made-up until it is printed. The end bars 11 may be readily lifted out of engagement with the bars 12 which thus in fact is a separation of the said bars. The use of a frame of the present invention allows all corrections, changes, overruns, etc. to

be made without taking the same off.

What is claimed is:

1. A type frame comprising bars in pairs of predetermined lengths, each pair of bars having parts which overlap portions of the other pair of bars respectively in the lengths of the bars and having portions which overlie each other cross-sectionally of the bars.

2. A type frame-comprising bars in pairs of predetermined lengths, each pair of bars having part which overlap portions of the other pair of bars, and said parts of each pair of bars respectively fitting in recesses in each pair of bars respectively, the Widths of the parts and recesses being substantially equal to one-half the Widths of the bars, and the thickness of the parts and the depths of the recesses respectively being substantially equalito one-half the thickness of the bars.

3. A rectangular type frame comprising bars in pairs of predetermined lengths, each pair of bars having angularly disposed parts Whichoverlie each other, and a portion of one bar beside each angularly disposed part contiguous therewith on the inside thereof,

4. A type frame comprising pairs of bars of predetermined lengths, the bars ofeach pair being identical in formation, each bar at each end thereof having an angularly disposed part equal in Width to substantially one-half the Width of the bar of which it forms a part, each recess equal in Width to substantially onehalf the Width of the bar 6. A frame comprising barshaving interfitting end portions which render; the :bars readily separable in one respect by lifting certain of said bars from engagement with the nextadjacent bars and insepa'rablein other respects by an inward force applied to the inner walls of said bars, the end portions 'of each bar fitting into recesses of another bar, and the idth of each of said portions 7 and recesses being substantially one-half the Width of said bars. 7

In testimony whereof I have aflixed my signature.

WILLIAM B. RENNER.
