TYPE-BAR AND SUPPORT.

SPECIFICATION forming part of Letters Patent No. 787,968, dated April 25, 1905.

Application filed March 12,1904. Serial No. 197,312-

To It/Z whom it puny come/Wit:

Be it known that 1, JOHN \Vmson, a citizen of the United States, residing at Brooklyn, in the county of kings and State of New York, have invented certain new and useful Improvements in Type'Bars and Supports, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a type-lair and support therefor, and particularly to a structure whereby a plurality of type-bars are supported upon a segment relative to the printingplaten.

The invention has for an object to improve the construction and arrangementof the type.- bar and its simporting-bracket, whereby a pivoting-bracket is provided for the bar capable of thorough adjustment while the bar is guided in its oscillation and the alinement thereof assured at the printing-point.

A further object of the invention is to provide an improved support for a plurality of type-bars which is inclined relatively to a vertical line and the bars disposed thereon in positions inclining toward a central point below the support, whereby the pivotal axis of each bar is maintained in a substantially horizontal position and any side play or pull thereon prevented which will occur when the pivotal point of the bar is thrown into other than a horizontal plane. This arrangement also materially economizes the length of segment required, as the bars travel in such planes as to prevent any clashing and permit the use of shorter bars, while a material saving in space is effected in the contact of the bars with the bar-rest therefor.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawings, Figure l is a plan showing the position of the support relative to the platen; Fig. 2, a vertical section on the line 2 2 of Fig. 1; Fig. 3, an enlarged detail of a type-bar and supporting-bracket; Fig. 4, an edge view thereof; Fig. 5, a perspective of the plate of the bracket; Fig. ('3, a similar view of the pin of the bracket; Fig. 7, an enlarged detail section on the line '7 T of Fig. 3;

Fig. 8, a vertical section through a segment disposed in a vertical plane with a modified form of the type-bar bracket applied thereto; Fig. 9, a similar view of another modified application of the bracket and type-bar to a vertically-disposed segment; Fig. 10, an edge view of the bracket shown in Fig. 9, and Fig. 11 an edge view of a segment similar to that shown in Figs. 1 and 2 and having securingslots therein.

Like letters of reference refer to like parts in the several views of the drawings.

The letter A designates a segment, which in the illustration here given is rectangularly formed and disposed at an angle of thirty degrees to a vertical line and at one side of a platen A. These parts may be of any desired size, construction, or configuration and the angle thereof altered as found desirable. This segment A is provided with a plurality of openings A" therein, which are preferably staggered, as shown in Fig. 1, so as to economize space in the mounting of the type-bars B therein. In the use of this support any desired form of type-bar may be provided; but a preferred construction thereof is herein shown. In this illustration the type-bar B is mounted in a bracket C, which is pro vided with a depending pin O, held in position within the segment by means of a screw or other fastening device A. These devices are disposed upon the opposite faces of the segment, so as to intersect the openings therein for the purpose of holding the type-bars in position. The series of openings in this segment are inclined downward from one face thereof toward a central point below the bar, and the inclination is such that the type-bar carried by the bracket is supported in a vertical plane with its pivot in a horizontal plane in order to avoid the side play, friction, and wear which occur when the bar is disposed in other than a vertical plane with its weight carried upon the pivot. In Fig. l the segment is shown as provided with apertures A therein; but if found desirable a similar result may be obtained by using slots or recesses, as shown at A, in a segment A, (illustrated by Fig. 1l,) these slots being disposed at snecessively greater angles to a central slot or recess in the progression thereof toward the opposite ends of the segment, which is inclined, as in Figs. 1 and 2, to bring the slots into a vertical plane.

The improved construction of type-bar B is provided at its outer end with the usual head B to receive the type and at its inner end with a tail B to which the usual connector is applied. Intermediate of the ends a pivoting-screw B is passed through a suitable aperture in the bar and an aperture C in the bracket C, upon which it is mounted. If found desirable, a bushing C may be inserted in the type-bar at the pivoting-aperture, as shown in Fig. 7, into contact with which the tapered head of the pivot-screw B is adapted to lie and have bearing. The free end of this screw is suitably threaded, as at 13*, and a lock-nut B applied thereto. At one side of the bracket C the type-bar is formed with a bifurcated portion B, which may be constructed in any ordinary manner for instance, by offsetting one portion of the body of the bar, as shown at B and applying an opposite shorter finger B", as shown in Figs. 3 and 4. The members B and B to this portion are connected together by a screw B, threaded therein and adapted to permit the adjustment of the parts laterally to the periphery of the bracket C, which is embraced thereby in the travel of the bar, whereby any lateral motion or twisting of the bar is prevented. bifurcated portion with laterally-extending lugs B T adapted to embrace or straddle a projection C carried by the bracket (J, which insures an accurate alinement of the type in its printing position and obviates the necessity of any type-bar-locking device adjacent to the platen.

The bracket-plates C are provided with a series of apertures C, which in connection with the body of' the type-bar B clean the sides of the bar of any lint or other dust collecting thereon, as there is a shearing movement of the type-bar in passing over the periphery of the openings. They also reduce the weight of material necessary in the formation of this part, which is preferably of hardened steel, so as to secure the most efficient wear and prevent any possible bending or twisting thereof when in use. The pin 0, which forms one means for securing this bracket in position, is adapted to be adjusted longitudinally of the under face C of the bracket-plate, which is necessary for different type-bars, as they are disposed in the staggered apertures or through openings provided for their support and obviates the necessity of varying the length of the bars. The head of the pin may be slotted, as shown at C and secured to the plate by clamping or soldering it in any well-known manner.

In Fig. 9 a modified application of the bracket and bar is illustrated, in which the The type-bar is also provided at itssegment A is disposed in a vertical plane beneath the platen A, while the type-bars swing upward from a horizontal to a substantially vertical position. This necessitates the application of the connector D at aslightly-different point from that shown in Fig. 3, and for that reason the tail D is disposed at the opposite side of the pivot from that before shown in order that the connector may lead therefrom in a horizontal plane. The bracketplate is also disposed in a position at substantially right anglesto that shown in Fig. 3, and the pin C applied to a face at right angles to its point of application shown in Fig. 3. This requires the connector to pass across the face of the bracket G, and for that purpose a depression or the channel D is formed therein sufficient in depth to permit the proper play of the connectorfor instance, as shown in Fig. 10. The position and operation of the other parts remain relatively the same.

In Fig. 8 a slightly-different manner of mounting the bracket C is shown, wherein the segment A has the bracket applied to one face thereof by means of a screw A, entering the segment and extending through an extension I), carried from the same face of the bracket as the pin C, (shown in Fig. 9,) but at one end of' said face.

The operation of the type-bars is effected in the usual manner, and the invention is intended and adapted to be varied for application to different classes of machines embodying the use of a plurality of type-bars disposed relatively to a common printing-point upon a platen. It will thus be seen that the positions of the bars on the segment are disposed at an increasing angle relatively to a central point as they approach the opposite ends of the segment, and effects a material saving in the length of segment required, while the length of the type-bars is also shortened and their disposition in a vertical plane prevents the liability of side pull or play, which occurs to more or less extent when the bar is inclined laterally to a vertical line. It also secures an even Wear upon the bearings and guides of the bars and prevents the clashing or contact with each other as they fall back upon the type-restat their rear, each of the bars being in such position as to closely nest with its associates when in contact with the rest. The material of the end of the bar may be suitably hardened to secure a proper bearing or a bushing may be used, as hereinbefore described, for that purpose, while the construction and arrangement of the bracket provides a positive guide for the type-bar in all of its operative positions, preventing any lateral springing thereof, which guiding-points may be adjusted to secure at all times the proper degree of contact to secure the most efficient result, while when the bar approaches the printing-point a lock is provided to insure positive alinement, thus obviating the necessity of any locking device disposed at the free ends of the bars and providing a bar which can be used and applied to any ordinary construction of machine in order to secure the minimum of friction in its bearing and the utmost of rigidity against lateral springing, while it is positively guided in its travel.

.1 t will be obvious that changes may be made in the details of construction and configuration in order to apply the invention to different characters of machine for which it is adapted without departing from the spirit of the invention as defined by the appended claims.
