Application filed ('ctober 1, r27, Serial No. 223,463, and in Germany October 8, 1926.
. invention relates-i to a re anism for typographical machines working with punched registering strips which coinprise several magazines.
111 these magazines different kinds of types can be stored, or the one magazine may contain the small letters and the other magazine the capital letters of the same kind of type. The reversing mechanism is substantially constructed as follows Each of the signor character-keys is connected by a releasing mechanism, with two e capements controlling the corresponding channels of different magazines. One of these escapcments is locked. This locking may be unlocked by the depression of the reversing key, the other escapement being then locked at the same time. Only one of the escapements is released a a time so that only one matrix or element is delivered from the magazine.
In machines, in which the capital an d small letters 01: one kind of type are stored in diliterent magazines, the reversing mocha .isin
requires a separate channel-changing mechanism. In the magazines tor the small letters several channels are arranged for certain characters of the alphabet, for instance for the small e which happens frequei ly in the German language. By a suitable changing-mechanism the elements are alternately discharged from the channels so that the channels are unitor 'ily en'iptied. This changing mechanism may he used also in connection with inono-magazinc-machines. lVhei'i it has to be used for multiple magazinemachines a separate mechanism ncces for selecting at the reversing a certain ch nel and for shutting or; the other chainn is the capitaldetters for instance E are less frequently used, only one channel in the second magazine is generally provided lo" the same. lVhen after the reversing the leasing mechanism would act in the manner on the second magazine, clemei would be taken also in th s case from several juxtaposed channels. As, however, owing to the less great frequency of the capital leteis, nds
only one capi tal dotter-channe to several small-letter-cl.annels, a adjusting mechanism arranged w leases only the releasing mechanism 1 one capital-l or-channel but not those for the other letiera-hannels. This locking is operated from the reversing key.
The improved reversing mechanism. ac cording to the intention, is shown, ivy way of example, in the accompanying drawing, in which V Fig. 1 shows in sideelevation the revers ng mechanism, the casing being sho in Lee tion.
Fig. 2 shows the reversing mechanism in elevation, viewed in the direction of the arrow in Fig. 1.

At the depression of the hey i a rod 2 is lifted and an elbow-lever 3 oscillated. (in this elbow-lever rests an e centric-trame 4, comprising an eccentric W hen the elbowlever B is oscillated, it releases the edge 1" of the eccentric 5 nine 4% so that this frame can drop, the eccentric 53 being thereby hroi ht into contact with a cylinder (3. The eecem ricitrame, oscillatably mount .d at the left end on a bolt 45, is then l ed and hits the re leasing rod 7 controlled by CW-O spiral-springs 7. The upper end of the releasing rod 7 is suspended on an elbow-lever 8 against which bear the ends 0:? push rods 9 and 10. The other ends of these push-recs bear against escapen'ients 11 and 12 which are rot tably mounted on bolts 11 and 152. prings 13 and 1e tend constantly to rotate the escapenients and to push thereby to the right the pushrods 9 and 10.
When the releasing rod 7 is litter of the push-rods follows the lililY merit el bmv-lever S, the other push-rod, for in? 9, being held at its nose 9 i y a locking evicc consisting of a shaft 15 which. is, for instance, of semi-circular or semi circular-ring shaped cross section (Fig. 2). The lower edge 15- of this shait 15 bears against the noses 9 of all the push-rods 9 arranged the one behind the other, as it extends over the entire tit) 21, controls a connecting rod 22 which is permanently pulled downward by the action of springs 23. At the depression of the reversing key 20 the rod 22 is pulled downward. whereby a toothed segment 24 is rotated in clock-wise direction This toothed meshes with spur wheels 25, 26 on the sin 1 15 and 27. The shaft 27 (Figs. 4a to c) is constructed in a similar manner as the shaft 15 and so adjusted that it liberates the noses 9 of the push-rods 9 locked by the edge 15 of shaft 15, while they lock the noses of the push-rods 10 when those of the pnz-ah-rods 9 have been released. At the movement of the toothed-segment 2st in clock-wisc-direc tion, the locking of the shaft is suppressed, and the edge 27 of shaft 27 bears against the noses 10 of the push-rods 10.
Although the keys 1 are connected with different channels only one element is liberated at a time by the locking mechanism. The locking is reversed by the dc pressing of the reversing key so that in this case the element taken from the second magazine. The reversing mechanism may be constructs ed in a shnilar manner for ui:-.rhine;--: with more than two magazines.
At a hasty depression of the reversing key 9.0 the reversing mightbe supp it after one of the sign-keys l bc'nw d rcssad. it separate locking-hook 30 ((L. llcd or a spring 31 is therefore irovided whir the rotation of the toothed segment sulting from the depression o f the rorcrs' key comes into engagement honi- (lei' of the toothed segment s as the locking hook 30 rests upon thi; der, the reversing cannot be su ut resser This can be done only, when the role; 7 of a key 1 is on the return-travel and along the bar 33 endin through 1101-. 34; of all the relea. ng rods 7.
The bar 33 is connected wi lb. an cll'iow-lei'er 35, on the upper arm of which a pawl as is hingedly mounted, which is control spring 37. The amplitude of will; the elbow-lever 35 may be re;. ;ul adjustable stop 38 on the casing. The ha r a is pulled by the action of a spring 23 aloiu with the returning releasingrodmnd the pawl 36 pulls to the left the lower arm 0 fthelocking hook 30 in opposition to the action of spri 31. The locking book 30 is consequently l lated by the pawl 36 so that it re: ise 1e toothed segment 24 'hich rotates backward under the action of the springs 33 on the rods 22.
hen the reversing key 2%! is leing pressed when one of the push-rods is sti in the working-p0sition owing to t depi sion of key 1 reversing upon the second an azine might. accidentally take place. this reason the suppressing of the low the shaft 15 is retarded at the re WVith this object in view the toothec 535 loosely mounted on shaft 15 and con nected with the same by a plate-spring ll) (Fig. l). hen the reversing key 20 is being depressed. the spur-wheel 25 is rotated, but shaft 15 prevented from participating in this movement as a lever ll is keyed on this shaft which bears against a rotatable abutment d5 on the shaft 27. This abutment moves out of the path of the lever ll only when the edge 27 of shaft 37 has come in front of the noses 10 of the push rods 10. At this moment the lever llis oscillated to the right by the action of the spring 5 .0 which has been put under tension byrotation of the spur-wheel 24:, so that the lever 41 rotates the shaft 15. The locking of the push rods 9 is therefore suppressed when theedge 27 of shaft 2? is lying in front of thenoses 10 of the push-rmls 10. lVhen the reversing is suppressed again, the lever llslides along the abutment in putting under tension the spring 43 until the abutn'ient 42 is standing again in front of the lever 11. V
The channel-changing-mechanism operates in the following manner. To the elbow-lever 3 so many eccentric frames 1 are co-ordinated as jurtapose l channels have to be alternately operated by the depression of the key 1. Only one of these eccentric frames may however be in the working position at a time. VVith this object in View the eccentric frames 4; have each an extension .50 with a shoulder 51. Looking pawls 52, 52", 52 co-operate with this shoulder. When the front locking pawl 52, as shown in Fig. l on the left side, is resting upon the shoulder 51, the abutment 1 of the eccentric frame 4 rests upon the elbowlever 33. At the depressing of the key 1 all the elbow levers 3 for the eccentrics are oscillated only the eccentric 5 cominghowever into contact with the cylinder 6 so that it is lifted together with its frame 1. A bolt 58 on the extension of the eccentric frame strikes at this occasion against the extension 5 1 of the next following locking pawl 52, which is thus lifted over the shoulder of the corresponding extension of the second. eccentric frame. At the oscillating movement of the first eccentric frame the pawl 52 drops, so that it assumes the position shown on the right side of Fig. 1. The second eccentric frame is now in the working position, the first and third frames being locked by the pawls 52 and 52 so that they do not restupon the elbow lovers 8.
When at the next following depressing of the same key 1 the second frame is lifted,
ing pawl 54 the locking pawl 52 into the posit-ion shown on the left side in Fig. l. A complete change is thereby obtained, one element has been taken from each of three juxtaposed channels of the same magazine by three consecutive depressions of the key 1.
The mechanism as described may be used also in connection with mono-magazine-machines. For the multiple magazine-machine illustrated a separate connection between the reversing mechanism and the channel-changing mechanism must be provided. With this object in view cam-shafts 60 are arranged behind the extensions of the eccentricframes 4, the cams 61 of said shafts entering not into function before the reversing. At the depressing of the reversing key 20 the cam-shafts are also rotated by a connecting rod 62. The extensions 50 and 50 are pushed outward by the cam 61, so that the corresponding eccentric-frames can no longer assume the working position. At the same time the front locking pawls 52 are disen gaged by the earns 63 so that, after the depression of the reversing key, the first eccentric-frame rests in the working position on the elbow-lever 3. At the depression of the key 1 only the same eccentric-frame and consequently the same channel of the second magazine 17 is therefore always operated, as long as the reversing-key 20 is suppressed. At the returning of the operated releasing rod 7 the locking of the reversing key is suppressed, so that the channel-changing-mechanism enters again into operation.
lVhen, therefore, the first magazine, in which the small letters are stored, is engaged, one element is discharged alternately from several juxtaposed channels at the depression of the key 1. The eccentric-frames control themselves mutually so that the frame in movement suppresses every time the locking of the following frame in order that the same comes into the working position. \Vhen a reversing is carried out, this changing mechanism is automatically put out of operation, and at the depression of the key 1 only one and the same escapement of the same channel in the second magazine is always operated so that the capital-letter-element is taken only from one channel.
