7 Claims. (01. 74-422) The invention relates to mechanical move: ments, and particularly to means for obtaining vernier adjustments, an object of the invention being to provide improved means for obtaining fractional adjustments of the platen of a listing adding machine, typewriting machine and the like to the exact printing line independently of the line spacing mechanism.,
The invention consists in the novel construction and combinations of parts as hereinafter set forth in thefclaims.
Inthe accompanying drawingwherein the invention is shownas applied to. the platen shaft of a listing adding machine,
Figure 1 is a side view of the invention as applied, with parts in section and parts broken away. v
Figure 2 is a section on. the line 2-2, Figure 1, with'partsbrokenaway.
c Figure 3 is a detail side viewof a modification,
with parts broken away. I Figure 4 is a section 'onthe line ,4'4, Figure 3.
Figure 5 is asection on the line 5-5, Figure 3. In the drawing, the numeral l designates the platen shaft, having hearings in the stationary framing.2,]said shaft carrying, a recessed, handle knob 3, provided with. an inturned inner sleeve l,
said sleeve having a threadedperforation engaged by a set screw 5 contacting said shaft to make, said. knob fast thereto. a Loosely mounted upon the platen shaft I is' a circular plate 6,having'a hub I, provided with a detent wheel 8, engaged by a spring. detent 9,
pivoted on said framing. 1
.The circular plate 6 has the outer lateral face thereof contacting the inner lateral face of the circular end plate I 0 of said handle knob from which said sleeve .dprojects inwardly, said end plate having an endless series of twelve equally spaced perforations or recessed seats H, and said plate 6 having an endless seriesof eleven equally spaced perforations or recessed seats [2, the two. series of perforations being both concentric with and equidistant from the shaft l and. the perforations being all of the same diameter. The ex-, tent of the intervals between the perforations of the twoplates" therefore differs in the two series. The end plate ID of the handle knob 3 is hereinafter referred to as the primary plate and the circular plate 6 as the vernier plate.
Loosely mounted upon the platen shaft I is a secondary handle knob I3, the inner end portion of which extends within the recessed main handle knob 3 and terminates inwardly ina recessed portion or cup 14 the inner circumferential edge engaging the perforations of said primary plate which is formed into a cam l5, an endless series balls or plungers l6, equal in number to and being, in cooperationwith a spring thrust member to be described; inthe rotation of said secondary handle knob and its cam in either direcin of said balls successively engaged with the aligned.
stment of, the primary plate the perforations the two plates become successively aligned and perforations to thereby laterally distort said ring thrust member. 7
This, spring thrust member comprises an annular coiledspring' l1, engaging an annular recess formed by theannular beveledsurface. [.8 and said vernier plate, said annular beveled surface I of the vernier plate.
e to forr'ningp'artof' a collar l9 fast upon the hub This spring thrust memr H, is caused to hug the vernier plate clue its engagement with, said beveled surface I8 and acts to thrust said balls successively outwardly of the aligned perforations of. the two plates in the vernier. adjustmentof the primary plate.
Since there aretwelve of the balls l6 and only eleven perforations of the vernier plate, any
movement rotatively of the secondary handle knob will impart one-twelfth of one-eleventh of its .degree of movement to said main handle knob andthe' platen shaft; that is to say, for each the main handle knob and the platen shaft will mpleterotation of said secondary handle knob be rotated one-eleventh of a rotation.
initiated directly by twirling the main handle,
Primary adjustment of the platen shaft I is knob 3 to any position determined by the detent wheel 8.
The secondary handle knob i3 and its cam are adapted to yield against the-pressure of a coiled spring 20 located on the platen shaft within a recess of said. knob, said spring abutting at its outer end against a thrust bearing 2i, located on the outer end of said platen shaft and held against outward movement by a screw 22 engaging a threaded perforation of the end'of said shaft, the secondary handle knob having slidable engagement with said thrust bearing and with the platen shaft, said spring holding said cam its work an'd'providing for smooth easy action case of inaccuracies of manufacture.
While the invention as described accomplishes an adjustment ratio of one-eleventh, other ratios may be obtained; for instance by substituting a twenty-one hole and ball primary plate cooperating with a twenty hole vernier plate, the ratio would be one-twentieth of a rotation of the platen shaft I for each complete rotation of the secondary handle knob.
In Figures 3, 4 and 5 of the drawing a modification is shown wherein the primary and vernier plates are provided with notches or recessed seats instead of perforations, the same reference characters being used differentiated by the exponent I.
In this modification the margins of the notches of the vernier plate act to successively thrust the balls outwardly of the aligned notches.
