ADJUSTABLE PIECE OF FURNITURE FOR PRINTING,

Filed July 14, 1934 Patented Sept. 22, 1936 PATIENT OFFICE ADJUSTABLE PIECE OF FURNITURE FOR- PRINTING, COMPOSING, AND THE LIKE Emil Benno Zimmermann, Berlin, Germany Application July 14, 1934, Serial No. 735,263 In Germany October 20, 1933 4 Claims.

This invention relates to'an adjustable piece of furniture, the parts of which interengage in the form of arms, and which is primarily characterized by the fact that, for the purpose of simplified production, .the arm and block parts are made in one piece and both interengaging parts which form the piece of furniture are preferably made alike.

For the printer the invention offers a novel piece of furniture which, amongst other things, renders unnecessary any patching when adjusting and locking up the forms and also any auxiliary material, such as lead furnitures, reglets and quads; The whole pressure exerted by the locking-up apparatus can act completely on the matter.

When employing corresponding serrations the invention can be employed at the same'time as matter ties and renders unnecessary the usual complicated method of tying-up. The individual pieces of furniture can be easily interconnected at the corners abutting at right angles so that the rectangular frame formed by the pieces of furniture according to the invention cannot accidentally fall asunder.

For the composiiton the piece of furniture according to the invention has teeth oppositely directed to the tying-up apparatus and preferably so that only the two outer arms of each piece of furniture carry locking teeth directed towards their free end.

The arrangement can be so chosen that one of the two outer arms of each piece of furniture is provided with teeth along its entire length, whereas the other opposite arm has one or several locking teeth only at its free end.

In order to prevent lateral breaking apart when the pieces of furniture are pulled the one out of the other, the arms can interengage by means of key and groove, in a suitable manner, so that a lateral sliding apart of the arm parts in the closed position is rendered possible by the fact that the arms having the guide grooves are provided with a lateral recess corresponding to the shape of the guide key.

The piece of furniture according to the invention is remarkable for the simplicity of manufacture and manipulation and for the possibility of cheap manufacture by repetition work, as in the of easily providing the locking teeth, so that the pieces of furniture with their resilient arms can instantaneously be adjusted for a fresh line length by a single manipulation. Any 'complicated mechanism is avoided, there are no auxil- 9 iary parts which can become lost, and consequently the invention is unlimited, time is saved for the manipulation and material is saved in the manufacture, the pieces of furniture according to the invention are light and comprise no separate oscillatable parts. As the long arms are resilient, an easy disengagement of the teeth can be effected at any time. The piece of furniture can, as above stated, be universally employed. The piece of furniture according to the invention is equally suitable both for the printer and also for the compositor, also as matter ties and for other purposes in printing works.

Several embodiments of the invention are i1- lustrated by way of example in the accompanying drawing in which:--

Fig. 1, a perspective view of pieces of furniture fitted together to form a chase.

Figs. 2 to 4 show a, toothed piece of furniture designed for the use of the compositor,

Figs. 2 and 3 with inwardly locking teeth and Fig. 4 is a cross sectional view of a form of construction with guide groove and key to prevent breaking out in lateral direction.

Fig. 5 shows in side elevation the employment of pieces of furniture for example as tying up device with inwardly directed locking teeth, these pieces of furniture adapted to be fitted together to form a frame as illustrated in Fig. 1, it being possible to prevent by keys the lateral breaking out in the direction of the arrow Fig. 5.

Fig. 6 is a longitudinal section showing longitudnal grooves accommodating the keys and having lateral apertures corresponding in the shape and length to the keys for use when the pieces of furniture are in telescoped position.

Fig. 1 shows the pieces of furniture fitted together to form an adjustable chase.

Figs. 2 to 6 show forms of construction in which the arms are provided with teeth. The most advantageous shape for the teeth is the sawshape, because the length of the teeth roots is equal to the pitch. The teeth roots may at the same time be used as a measure for an adjusting scale as shown in Fig. 3. The pitch of the teeth is preferably chosen to correspond to the non- I pareil size in the case of the forms of the invention developed for use in the composing room.

The forms of construction shown in Figs. 2 and 3, as they can be slid in longitudinal direction, are best suited for the composing room. Preferably only one or both outer arms of each piece of furniture is or are provided with teeth. The teeth on at least one arm advantageously extend over the entire length thereof. The coordinate arm of the other piece of furniture need only have one or a few teeth.

In the piece of furniture illustrated in Figs. 2 and3 and composed of like parts 5 an arm of the part 5 has on its outer side locking teeth 5a extending along the entire length of the arm, whereas the opposite arm 5b has merely a few teeth. If the piece of furniture formed of the two parts 5 is too short, it can be extended to the required size by pulling the parts asunder in longitudinal direction as the teeth on one part are oppositely directed to those on the other, the

arms 52) being sufliciently resilient, so thatthe teeth of 5b can slide over the teeth of 5a.

In order to prevent a lateral breaking out of the extended partsof the piece of furniture in the direction of the arrows Figs. 1 and 3, keys, for example in the form of inserted pins, noses or the like I0, slidable in guides I, may be provided.

Fig. 5 shows the construction of the adjustable pieceof furniture according to the invention as a matter-tie or chase in such a manner that the teeth l4 on the arms la, 2a are directed inwards and the block ends I, 2 of every two parts of the piece of furniture, abutting at'right angles as shown in principle in Fig. 1, are so interconnected that the chase, each of the sides of which is composed'of the parts I and 2, is narrowed by a pressure exerted on the ends thereof in the direction of the arrow I5, and automatically locked in the narrowest position. A chase or matter-tie thus composed can be narrowed by simple hand pressure, the chase exerting a uniform lateral pressure upon the matter along its entire length and in this manner allows of transporting the locked-up matter. Such a tying-up device can onlyxbe produced if the individual parts have the base shape of the piece of furniture according to the invention.

To enable the furniture parts I and 2 tobe taken apart in lateral direction, in closed position, the walls of the guide groove 1 have an aperture 16 corresponding to the length of the key In and enabling the free removal of the key In in lateral direction.

I claim:-

1. A piece of furniture comprising two similarly constructed parts, in which one of the two outer arms of each piece of furniture is provided with a guide groove, and the other outer arm has an inwardly directed key, thekey of one part adapted to engage in the guide groove in the other part to prevent the two parts breaking out laterally one of the walls of the groove having an aperture to allow the keys to be removed from the grooves and the. parts to be taken asunder in lateral direction when in closed position.

2. An adjustable piece of furniture, comprising two identically constructed parts with a plurality of parallel slidably interengageable arms, the outer side of one of the outer arms of each part being provided with outwardly directed teeth along its entire length, and the inner side of the other outer arm being provided with inwardly directed teeth on only a portion of its length, the inwardly directed teeth of each part adapted to engage the outwardly directed teeth of the other part to prevent accidental shifting of the two parts.

3. An adjustable piece of furniture as specified in claim 2, in which the inwardly directed teeth along only a portion of the length of one arm of each part project above the surface of the remaining portion of this arm to form a recessed portion that moves Without friction over the outwardly directed teethon the other part of the piece of furniture.

4. An adjustable piece of furniture as specified in claim 2, in which the inwardly directed teeth in each part are on the free end of their arm.
