ROBERT N. RUSSELL, EARL W. LESHEB, AND ALFRED J. MEUNIER, OF CLEVELAND, OHIO, ASSIGNORS, BY MESNE ASSIGNMENTS, TO THE ADVANCE MANUFACTURING COMPANY, OF DETROIT, MICHIGAN, A
CORPORATION OF MAINE.
PRINTING MECHANISM.
Application filed August 23, 1913, Serial No. 786,308.
To all whom it may concern:
Be it known that we, ROBERT N. RUssELL, EARL WV. Lnsrmn, and ALFRED J. MEUNIER, citizens ofthe United States, and residents of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Printing Mechanism, of which we hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to a printing mechanism, particularly to the printing drum and the means for holding type thereon.
One object of the invention is to provide means for rigidly securing the type in place on a printing drum or cylinder to permit printing therefrom.
Another object of the invention is to provide improved type clamping means adapted to retain type in engagement with the surface of the cylinder and prevent them from becoming loose thereonor from moving in a radial direction relative thereto.
Another object of the invention is to provide means which secure the type in close engagement with the cylinder and drum and against movement relative to each other, whereby the printing drum will form an effective support for the inner ends of the type and accurate and positive printing effects may be obtained.
Other objects of the invention will be apparent to those skilled in the art from the following description.
For the purpose of illustration, we have, in the accompanying drawings shown and herein described one form of printing mechanism embodying our invention.
Figure 1 is a view partly in elevation and partly in section of a printing drum embodying our invention;
Fig. 2 is a transverse section of the drum;
Fig. 3 is an end elevation of the drum.
Fig. A is a perspective view of a portion of the periphery of the cylinder showing portions of two rows of type mounted thereon;
Fig. 5 is a side view of one type showing rectangular opening therethrough;
Fig. 6 is an end view of the type;
Fig. 7 is a perspective view of one of the clamping segments over which the type are sleeved;
Specification of Letters Patent.
Patented Nov. 12, 1918.
Serial No. 227,604.
Renewed. April 9, 1918.
Fig. 8 is a perspective view of one of the spacing or justifying segments;
Fig. 9 is a perspective view of one of the spring clips employed to retain the type upon. the type holding segments;
Fig. 10 is a side view of a non-interlocking form of type; and
Fig-11 is a side view thereof.
In these views A represents a printing cylinder or drum preferably mounted upon a rotatable shaft B. The cylinder or drum is preferably provided with terminal flanges C, between which type D are secured. The flanges C may be formed integral with the cylinder or drum, as-shown in Fig. 1.
Each type D preferably has tapering sides (see Figs. 6 and 11) and is formed with an opening D through its body portion. The opening D is preferably of rectangular shape.
E indicates as an entirety a segment or curved member on which one or more type D are adapted to be sleeved and secured to the cylinder A as will be later described. The segment E is curved on an arc struck from the axis of the cylinder A so that it is disposed parallel to the cylinder when positioned thereon. As a re sult of this construction, all the type in each row of type. are uniformly held against the cylinder. By forming openings in the type and extending the segment therethrough, the rows of type may be placed in abutting engagement to permit printing with minimum space between the rows of type.
The openings D in the type are of a size to permit them to be easily threaded on the segments, or the latter inserted in and removed therefrom, but in order that the segments may rigidly secure them to the cylinder A, the bottom walls 03 of the openings D must be equally distanced from their lower edges, so that the segment E will engage the wall d of each and every type in a row, as shown in Fig. 2. When so constructed the segment E will engage each type D in the row and firmly press it against the cylinder.
E indicates a hook provided at or near one end of the segment E. E indicates a correspondingly hooked flange upon a cross bar E secured in any well known way to the cylinder A. The hooked end E of the segment E is introduced under the hooked flange E these elements preferably serving as a pivot about which the segment E may be swung to position the other extremity E of the segment down behind the flange E secured in any desired manner to the other side of the cylinder. E indicates a shoulder provided on or near the end E of the segment E. F indicates a device adapted to engage with the extremity E of each seg' ment E to secure the latter to the cylinder. The type securing device F preferably comprises a rod extending longitudinally of the cylinder A and rotatably mounted at its opposite ends in the beads or flanges C thereof.
F indicates a shoulder provided on and extending longitudinally of the rod F. The shoulder F is adapted to engage the shoulder E on the segment E and exert tension thereon to press the type D against the cylinder A.
The rod F is preferably rotated by suitable means, indicated as an entirety at G, which may be constructed and arranged to lock the rod against rotation when released. The operating means G preferably consist of a worm gear 9 fixed to the extended end of the rod F anda worm Gr mounted in suitable bearings upon one head of the cylinder A. The worm G may be turned by means of a milled head G As the worm G prevents the worm gear 9 from turning, it'will be seen that when the head G is rotated to turn the rod F inthe direction to clamp the segment or segments E against the type D, the rod F is locked in the position to which it is moved so that the type cannot thereafter become loose.
The circumferential rows of type may be justified by means of spacing segments H, H. The spacing segments H are preferably provided with clamping segments H, H, which are similar in construction to the type holding segments E. The segments H are inserted in grooves formed in the opposite sides of the spacing segments and secured therein by screws 71,.
Each row of type, when sleeved on a segment E, engages at one end shoulders c, 0, adjacent one end of the segment. The type D- of each row may be held together and against the shoulders e, e, by a spring clip J (see Figs. 1,2 and 9). Each clip J is preferably formed from a piece of sheet metal.-
Centrally the clip is formed with an opening for the passage of the segment E. The opposite ends ofthe clip are curved backwardly to form sides J which yieldingly engage the body of the segn'ient. The sides J may be slitted at J J to provide portions J which may be bent to inclose the inner and outer edges of the segments E.
In Figs. 5 and 6 we have shown a slightly modified construction of type D in which it is provided on one edge with a groove (Z and on the opposite edge with a ridge (Z the ridges onthe type D in one row extendtion.
1 indicates a plurality of adjustable devices carried by one of the cylinder heads and adapted to engage the segment H at one end of the cylinder and through it compress the rows of type together. The de vices I preferably comprise screws, extending through screw threaded openings in the cylinder head or flange C. I
From the foregoing description it will be seen that the type may be readily positioned on and removed from the cylinder A. It will also be seen that the clamping means operate to maintain the type in rigid rela tionship to each other and the cylinder, so that the latter serves as a rigid back and support so that proper printing impressions can be readily made. I
To those skilled in the art of making mechanism of the class described, many alterations in construction and widely differing embodiment and applications of our invention will suggest themselves without departing from the spirit and scope thereof. Our disclosures and the description herein are purely illustrative and are not to be in any sense limiting.
