lb @ZZ whom it con/corn:
Be it known that}, CnAnLns Ronnnrcrr, a citizen of the United States, residing at Woodstock, in the county of McHenry and State of Illinois, have invented'certain new and useful rm rovements in Lateral Looks for Carriage S 'ftFrames; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being no lhad to the accompanying drawings, and to the letters of reference marked thereon which form a part of this specification.
This; invention relates to a novel construction in type-writing machines of that class in which the t pe-hars are provided each with a plurality oi types and the paper-carriage is lsupported and has endwise movement upon a shift-frame, which shift-frame is moved or shifted on the main frame of the machine to '20 bring the platen in position for the action on.
3.0 an Oliver type-writing machine; but the features of improvements embodying the invention may he used in connection with typewriters of other kinds that are provided with avplaten-shift device.
shown in the said'draw ings, Figure 1 is a view in side elevation of the rear end of a carriage shift-frame of an Oliver type-writing machine with the guide rod or'stem thereon L and thestandards on the machine base-plate s h which said gu de rod or stem is supported.
ig.- 2 is a plan view of the parts shown in ig. 1. Fig. 3 is a vertical section taken upon line 3 3 of Fig. 1. Fig. i is a perspective view of oneof the tapered blocks on the said rod or stem,
,As shown in the drawings, A. indicates the base-plate of the machine; B, the rear portion of the shift-frame, and C' the guide rod orste'ni, which is attached to the rear end of the shift-frame and has endwise movement with the shift-frame as the'lat'ter is shifted forwardly and haclrwardly to bring the' platen in position for the action thereon of either one of the types on the type-bars.
D indicates the standard which is attached to and rises from the basc plate A and which is vertically-slotted in its upper part for the passage of the guide-rod and to receive a guide-roller D, which is journaled in the "standard and onwhich rests the rear end of the guide-med.
D? designates the second standard on the base-piste, having an open notch at its upper endthrough which the guide-rod C passes.
c c are stops on the guide-rod located at opposite sides of the standard D and adapt edforcontact therewith in such manner as to limit the forward and rearward movement of theguide-iod and the shift-frame, to which itlis attached. Said guide-rod is shown as screw-threaded in its part adjacent to the standard D and the stops 6 c as having the form of nuts applied to the screw-threaded portion of said rod.
The standard I) extends above the guiderod G, and to its up er and is attached. a horizontal plate E, which is attached to the lateral parts of the standard by means of screws c e. In said plate E centrally over the guide rod 0 is located a set-screw e, the lower end of which is located closely adjacent to the guide-rod and which serves to hold said guide-rod from rising. So far as described the parts are constructed in the same manner as the correspondingparts of the Oliver typewriter as heretofore constructed.
Now referring to thelnovel features constitilting my invention, the carriage shift frame is provided with oppositely-inclined or oh lique contact-surfaces and the machine-frame with like correspondingly inclined or ob lique contact-surfaces, which surfaces in the shift-frame and machine-frame are located in position for contact with each other at each limit of the throw of the shift-frame. As shown in the drawings, the oblique surfaces faces of tapered blocks F F, attached to the guide-rod Oat the front and rear of the standard D, while the inclined surfaces on the machine-frame are formed by the outwardly-divergent sides of oppositely-facing tapered notches E E in the plate E, Said plate E is extended forwardly and rearward] y on the shift-frame are forincdby the sideinclined surfaces of the notches.
from the standard D, the notches E E being formed in the marginal parts of the plat-e above said rod C. The blocks F F are tapered to correspond with. the notches and correspondingly-inclined side Walls of the notches E E at each limit of the movement or throw of the shift-frame, the notches and blocks being arranged to come in contact with each other at the time one of the stops 0 or c on the stem strikes the standard D Said stops serve to accurately determine the position of the platen relatively to the types, while the interfitting engagement of the notches and blocks hold the shift-frame from vibratory movement.
The result of the construction described is that while the stem is adapted to slide or move freely in the guide-standard D in the endwise movement of the said stem, yet at each limit of such endwise movement the stem is positively locked against any lateral shiftingor vibratory movement by contact of the inclined surfaces of the blocks with the words, the oblique or inclined surfaces on the shift-frame stem, and. on the standard D by coming into inter-fitting contact with each other at each limit of the movement of the shift frame positively lock or hold said shift-frame from lateral vibration or movement. This is a matter of considerable importance, because thc impact of the types upon the platen takes place innnediately' after the platen has been shifted to the forward or rearward limit of its throw and any displacement of the shift-frame which might take place at that" time will result in the making of imperfect impressions.
While I have shown. the contacting parts having the tapered or oblique surfaces referred to as applied to the guide rod or stem on the shift-frame and to the guide-standard of an Oliver type-writing machine, yet the features of construction embodying the invention maybe otherwise applied to the shiftframe and stationary part of the machine, and such features may be employed in connection with the shift-frame of machines other than the said Oliver type-writer. Moreover, the features constituting my invention may be applied to a single-shift machine as well as to a double-shift machine. It will therefore be understood that 1 do not wish. to be limited to the details of construc tion and arrangement of the parts illustrated in the accompanying drawings except so far as the same may constitute sub jcct-mattcr of specific claims.
In other ,chned, oblique surfaces, the oblique surfaces on the shift-frame being adapted for contact with those on the main frame at the end of the throw of the shift-frame and stop-surfaces on the mainframe and shift-frame adapted to positively limit the throw of the shift-frame.
3.v A type-writing-machine frame and a carriage shift-frame provided one with a tapered block and the other with a plate having a correspondinglytapered notch, said block and notch being adapted for interfitting contact with each other at the end of the throwof the shift-frame.
4. A'type-writer frame and a carriage shiftframe provided one with a tapered block and the other with a plate having a tapered notch, said notch and block being adapted for interfitting contact at the end of the throw of the shiftframe, and stops on the main frame and shift-frame adapted to positively limit the movement of the shift-frame at the end of its throw.
5. The combination with a type-writer frame provided with a guide-standard, of a shift-frame having a guidcrod engaged with said standard, said guide-rod being provided at opposite sides pf the standard with tapered blocks, and the standard being prov ed with oppositely-facing tapered notches adapted to receive said tapered blocks at opposite ends of the throw of the shif t--fra1ne.
6. The combination with a type-writer frame provided with a guide-standard, and a stop-standard, of a shift-frame provided with a gui a-rod adapted to engage said guidcstandard; said guide-rod being provided at opposite sides of the guide-standard with tapered blocks and the guidestandard being provided with tapered notches to receive said blocks at opposite limits of the throw of the shift-frame, said guide-rod being also provided with adjustable stop-shouldcrs adapted for contact with the stop-standard to positively limit the throw of the shift-frame.
