WHITLOCK, OF ANGELES, CALIFORNIA, ASSIGNOR TO RALPH G. WHIT- LOCK PATENTS, ING., OF LAS VEGAS, NEVADA, A CORPORATION OF NEVADA DRIVE FOB A PRINTING MEMBER, INKING DEVICE, AND GUARD Application med February` 2s, 1929. seriai No. 342,091.
This invention relates to means for indicia printing so called metered permit mail and more particularly to a movement for time relating the printing member and a guard therefor.
Among the objects of my invention is to positively relate the cycle operations cf the printing member and the guard whereby to obtain absolute coordination throughout their relative and various functionate movements, and to prevent unauthorized movements of the printing member.
My improvements consist in the novel construction, arrangement and combination of parts ashereinafter fully, clearly and concisely described, definitely pointed out in my claims, and illustrated by the accompanying drawings, (2 sheets) in which- Fig. 1 is a longitudinal sectional elevation of a printing press constructed in accordance with my invention.
Fig. 2 is a transverse sectional e-levation, taken substantially on the line 2-2 of Fig. 1, showing the movement for the printing member.
Fig. 3 is a similar elevation taken substantially on the line 3?-3 of Fig. 1, showing the movement for the guard. The machine, generally may be any device having recording mechanism to be set by the postmaster for a given number of impressions and which automatically locks when such impressions have been exhausted as for example, the machines shown in my applications, Printing Press, Serial No. 40,631, filed June 30, 1925, and Meter Press, Serial No. 319,147, filed November 13, 1928. Inasmuch as the referred to record mechanism and the automatic lock form no part of the present invention, except in combination, I will omit their detailed illustration and description.
Referring to the drawings, by numerals,
i 10 designates a casing in which there is a main, or driven, shaft 11 for the movements of the printing member 12 andthe printing member guard 13.
Carried on the shaft is a gear element 14 forming part of a recording mechanism and lock Vand a unidirectional device 15, such as are described in the applications referred to.
Formed in the casing there is a mouth 16 through which the mail pieces, or letters, are fed to receive impressions and carried by the casing and exposed by said mouth is a platen 17.
Within the casing opposite to the platen is a track, or guide, comprising opposed rails 18, fixed to the sides of the casing, between, or in which, is mounted a slide, comprising spaced bars, or elements 19, and to which slide is secured the recited printing member 12.
A cam 20, of circular shape, and having a. diameter substantially equal to the spacing of the recited bars 19 is eccentrically mounted on the shaft 11 and xed to rotate therewith as by the collar 21 and set screw 22. To facilitate the placement of the cam relative to the slide bars 19, and to cooperate with the set screw 22 to prevent play in the cam I provide a flange 23 on each bar 19, and to, at least partially, compensate for variable thicknesses of mail pieces, I interpose a cushion 24, such as rubber, between tlie printing member and its carrier, the s 1 e.
The guard 13 for the printing member comprises a wall 25, which surrounds, or partially surrounds, the printing member, and a. support, for the walls, formed as a pair of arms 26 integralwith the walls and mounted to rock, as upon pivots 27, in a path comprehending the path of the printing member at all times.
Carried by the guard, preferably upon anY arm 2S, extending between the arms 26, is a roll 29 and carried on the shaft 11 to rotate therewith opposite to the roll is a face cam 30, having a groove, or roll path 31, as shown in Fig. 2.
An inking device is provided and arranged for movement into and out of the path of the printing member, by preference such def vice includes an inking pad 32, at whose sides there are keys 33 for riding in tracks, or ways, 34 formed in, or carried by, the arms .26 of the guard and a link motion 35 connecting the pad with the guard, as best shown in Fig. 1.
As best shown in Fig. 3 the sides of the cam groove comprise five distinct lengths, which in the order of action upon the roll 29, as indicated by the direction arrow, are first, al length 36, bearing such tangential, or angular, relation to the edge of the rcam 20 shown by dotted lines in Fig. 3, for the operation of the printing member, as to cause an initial movement of the guard prior to perceptible movement of the printing member to the end that the inking device is freed from, or moved to clear the type face.
Following the length 36 Ais a second length 37 bearing such angular relation to the edge of the cam 20,as to cause the gua-rd to be brought to rest upon the platen, or upon a mail piece supported thereon in advance of the movement of the printing member to the plane of impression, to the end that the guard box surrounds (protects) the printing member during all of its movement to print, or toward the platen.
Following the length 37 isla third length 38 substantially concentric to the shaft, which functions to hold the guard, with pressure, on the platen, or mail piece during the entire impression interval.
y ollowing the length 38-is a length 39, which is substantially the physical opposite of the length 37 and which functions to move the guard in a restoring direction in advance of the movement of the restoring movement of the printing member, and finally, following the length 39 there is a length 40, which-is substantially the physical opposite of the length 3G, and which functions to cause the ink pad to be brought to engage the type face with percussion whereby to effectsubstantially uniform and clean inlringrof the entire type face. y
The various cam lengths coact with the `link motion to first move the guard toward the platen to effect separating the ink pad from the type face; then by continued movement of the guard'cause the inl: pad as separated from the type face to be withdrawn in a path at substantially a right angle relative to the path of the printing member, then by continued movement of the guard in a guard restoring direction return the pad still sepa.-
rated'from the type face to the path of the printing member kand finally cause the pad to be .rapidly moved in a path substantially ,A paralleling the path of the printing member and brought as by impact to position aga-inst the type face.
The means, which translates the rotary motion of the main driven shaft to linear or reciprocating motion of the printing member and comprising the described cam and spaced bars of the printing member slide,
' prevents any movement of the printing inember, except by rotationk of the shaft and there- L by reduces to a minimum unauthorized impressions from the type, or indicia, of the printing member.
The form of the device illustrated and described herein is submitted in accordance with statutory requirement by way of exhib- 'iting one form of embodiment of my invention. Various changes, alterations or modifications of the structure may be made without departure from my invention as defined in the following claims. I claim:
l.
