Ori inal application filed May 18, 1894, Serial No. 511,685.

Serial No. 33,264. Divided. and this application filed June 22. 1910.

To all 20710121 it mag concern Be it known that I, l nnnnnro IV. HILLARD, of Bentley Manor, in the county of Richmond and State of New York, have invented a certain new and useful Type-"Writing; Machine, of which the following is a specification.

My present application is a division of my pcin'ling application Serial Number 511,685 which was filed May 18, 1894, and of my divisional application thereof Serial Numbcr 33,261. filed October 16, 1900, now Patent Numher 1.027 843, patented on the 28th day of May. 1912, and the present application is .filed in response to requirement of division made by the Patent Office.

In the accompanying drawings which form a part of this specification: Figure 1.

is a plan View of the machine with the greater part of the carriage removed and the carriage rack-partially broken away. Fig. 2 .is a sectional side elevation of Fig. 1 and shows the carriage in place. Fig. 3 is a rear elevation of the machine shown in Figs. 1 and 2, and it shows in full lines the carriage rack which was shown partially broken away in Fig. 1.

My present application relates to the earriage structure and to novel, simple and advantageous means for shifting the carriage from lower case to upper case printing position and vice versa and the invention comprises also a. novel method of connecting the carriage. rack with the carriage so as to permit ofa' relative movement of the carriage in relation to the engaging teeth of the rack, and of mechanism in the machine whereby theengaging teeth may be main tained in their carriage controlhng position during the said shifting movements of the carriage from printing case to printing case, and it further consists in key operated means for operating said controlling mechanism, so as to move the rack out of its carriage controlling engagement and thus to release the carriage from the e'scapemcnt.

Referring to the drawings. the entire carriage, including the platen frame and platen, and thetruck 43" and carriage rack '13, the running gear comprising front wheel 62 Specification of Letters Yatent.

and. rear yokes 63 03 and the release key and lever 60, (51, etc, is mounted on the shift frame, which latter wholly supports said carriage. The shifting guide rails or and '63 and the rocking members on which they are mounted constitute said shift frame; the said shift frame being pivoted to the main or stationary frame by means of the pivotal supports which are shown in the drawings. The front rail. is mounted on the rocker arms 65 and The rocker arm (35 has two branches at the lower extremity, one (35", ex tending toward the front, and the other (35 extending toward the rear of the machine. To the front end of the forwardly extending arm (35" is attached spring 66, which holds the carriage normally in forward position for printing lower case characters, and to the rear end of the rearwardly extending branch 65 is attached the eonndcting wire 6'1 which is fastened at its lower end to the shift key lever. The rear rail is mounted on rocker arms 63*, 63 at the rear of the rna-' chine. Extending between the front and rear arms are the connecting rods 68, 68. When the shift key 11 is depressed the front guide rail (32 is rocked rearwardly, and the motion is transmitted to the rear guide rail (33 through the connecting rods 68, (58. The carriage is thus shifted rcarwardly as a whole including the plafen carriage and the truck 43" and the upper hinged edge of the rack member 43 which is hingedon the truck bringing the platen into position. for the printing of upper case characters. lief ferring to the drawings, it will be seen that the front carriage guiding and supporting wheel 62 encircles more than onehalf of the front guide rail 62. and that the sliding carriage yokes 63 (33 on the rear o'fjhc carriage wholly encircle the rear guide rail 63. Hence it is clear that the carriage itself, through front whcel lii and rear yokes '63. (33, may constitute a means whereby. the rear rail 63 is shifted when the front rail (12 is shifted. During the shifting movementof the carriage to the rear the engaging teeth of the carriage rack are restrained from rearward movement h the rack guide lot return movement of the carriage to lower case position the rack teeth are restrained from corresponding forward movement by said rack guide and its spring 37. Hence it is obvious that my construction is one wherein the carriage can be shifted as a whole, in-

cluding the platen carriageand the truck,-

from lower case to upper case and vice versa, without any corresponding movement of the engaging teeth of the carriage rack; and that I have accomplished such result by jointing the rack member upon the truck so as to permit of a relative movement between said truck and said rack member during the to the precise construction shown herein,

but wish to have it understood that I claim broadly herein a carriage which is shifted or oscillated with its running gear, upon rails or tracks, in combination with a guide or holder for the carriage rack, arranged and adapted to maintain the engaging teeth of the rack in their carriage controlling engagement during such shifting movements of the carriage. My running gear here shown comprises front carriage roller 62 and the rear carriage yokes 63 63 Near the left hand end of the rack is the arm 43, which extends over the guide rail 63 and is then bent downwardly until its front end lies only slightly above the top plate of the machine. Pivoted to the left hand side of the platen frame is the release lever 61, which carries on its front end the release key 60 and has its rear end so placed that when the release key is depressed the rear end will engage with the rack arm 43* and rock the rack inwardly or toward the front of the'machine out of engagement with dog 30. It will thus be observed that -when the release key is depressed and the rack 43 thereby swung forwardly of dog 30, the carriage will be free of the escapement, since both dogs 30 and 31 will then be disengaged from the rack. Hence the carriage can be moved by hand in either direction, forward or back in its line of feed, so long as release key 60 is held down.

leferring to Fig. 2 of the drawings it will be observed that the rear end of the release lever 61 is so formed that it will slip under lhe releasing arm 43 of the rack member farther when the carriage is shifted back to upper case than when it is in lower case position, but that said rear end of the release lever is bent into a horizontal plane so that such shifting movements do not interfere with its proper relation with the rack arm. lVhen the platen frame is lifted up for inspection of the writing, however, the release lever 61 does not engage with the rack arm 43 The part numbered 34 in the drawings may be indifi'erently styled the rack guide or the rack holder, since it serves both to hold the rack and to guide it into and out of engaging position.

It will be observed that I shift the platen carriage by a parallel movement from the one printing case to the other so that the printing point is in the same plane in lower case as in upper case, also vthat I provide an oscillatory .movement for one member of the truck (here shown as the rack member) whereby the carriage may be shifted as a whole (including the platen frame and the truck) and the platen frame be moved by a parallel movement without disarranging the proper engagement between the carriage and the escap'ement.

In Remington typewriters, of which my present machine is a modification, and in many other commercial typewriters, each type bar is provided with two characters, a lower case letter and an upper case letter,both letters lying in the same plane and having their faces-parallel with each other. There are many advantages in such parallel arrangement of the type characters. But if the two type characters are parallel with each other, then the printing surface at the platen must also be in the same plane in both cases, and consequently the platen frame must be moved by parallel .motion from the one printing case to the, other. But meantime the rack member must be held in such position that the carriage is controlled by the escapement in both cases; That is to say the rack teeth must be held in their carriage controlling engagement in both positions of the carriage. I have met the requirements of the problem thus pre sented by providing a carriage having a platen frame and a truck hinged together and a rack member hinged upon the truck, and by further providing running gear and two oscillatory supports for the carriage and means to cause said supports to rotate in unison so as to maintain the surface to be written 011 in parallelism in both cases, and by still further providing a holder for the rack member so that during said shifting movements there will be an opening and closing movement between the truck and the rack member, whereby the engaging teeth of the rack will be maintained in their car riage controlling position during the shif ing movements and in both positions of the carriage.

It will thus be seen of how great importance is the joint between the truck and the rack thereon in my machine, since it permits of the parallel movement of the platen frame while still reducing the shifting motion to zero at the engaging line of the rack teeth. I am not aware that any typewriter has ever heretofore been provided with a parallel motion of the platen frame from the one printing case to the other and an oscillatory reducing movement in the truck whereby the engaging teeth of the rack are maintained in their carriage controlling position during such parallel shifting movement of the platen frame, and I'therefore claim such mechanism broadly herein.

It will be further observed that in my present machine the entire carriage (both the platen frame and truck and the parts thereon) is Wholly mounted on the shift frame. This I also believe to be broadly new and claim it herein accordingly. That is to say, my structure herein shown comprises three elements, namely the platen frame, the rack bar and an intermediate element connected both with the platen frame and with three said elements on the shift frame. I

also claim broadly herein thejoint between the truck and the carriage rack, whereby an opening and closing movement is provided between said parts during the shifting movements of the carriage.

Attention is called to the fact that my present carriage comprises a platen frame and a truck hinged together by one joint, and a :arriage rack hinged to the truck by a second joint. I believe such combination to be new and claim it herein accordingly.

It will be obvious that my invention is of wide application and I therefore do not intend to limit myself narrowly to the specific details shown in the drawings.

Having thus described my invention, what I claim and desire to secure by Letters Patent is as follows:
