TYPE-BAR AND HANGER.

Specification of Letters Patent.

Patented April 6, 1909.

Application filed July 20, 1908. Serial No. 144,415.

To all w/tom. it may concern:

Be it known that l, VvILLlAM E. BURNETT. citizen of the United States, resldmg at llion. county of ll erkimer, and State of New p York, have invented certain new and useful lmprovemei'its 1n Type-Bars and Hangers,

of which the following is a specification, ref

erence being had therein to the accompanying drawing.

This invention relates to a type bar and hanger, and particularly to a structure by which the type bar may be adjusted relative to its support and segment and securely held at such adjustment.

The invention has for an object to provide a novel and improved construction of type bar hanger embodying a headed bolt adjustably connected with the hanger and having cooperating securing means arranged to produce a longitudinal movement of the bolt in its socket thereby drawing the hanger against the face of the support to clamp itin adjusted position.

A further obj ect of the invention is to provide the hanger with an interlocked or mortise connection with the bolt head topermit adjustment thereon laterally of the bolt and to provide the bolt with a seat against which a bearing screw may contact said screw being disposed at such an angle as to effect a pressure longitudinally of the axis of the bolt.

Another object of the invention is to provide a headed bolt for adjustably retaining the type bar hanger, said bolt being of circular cross section disposed in a correspond iug socket with a circumferential bearing face to engage a retaining device whereby a rotative adjustment of the bolt may be effected.

A further object of the invention is to.

provide an improved construction of the hanger having a pintle or pivot adapted to cooperate with ball bearings carried by the bifurcated inner end of the type bar.

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

In the drawing :F igure 1 is a vertical section showing the application of one form of the invention; Fig. 2 is a detail perspec tive of the type bar hanger shown in Fig. 1; Fig. 3 is a similar view of the headed bolt shown therein: Fig. i is a perspective showing a modified form of hanger for adjustment parallel of the type bar pivot; Fig. 5 is a similar view of the cooperating bolt; Fl U is a horizontal section through these arts as assembled in Figs. and 5; Fig. 7 is a vertical section showing a modified form of hanger; Fig. 8 is a similar view showing a modified form of bolt; Fig. 9 is a detail perspective of the hanger shown in Figs. 7 and 8; Fig. 10 is a similar view of the bolt shown in Fig. 8. Fig. 11 is a vertical section of the hanger shown in Fig. 9; Fig. 12 is a detail perspective of the type bar pivoting end; Fig. 13 is a vertical section showing a modified form of bolt; Fig. 14: is a detail perspective of this bolt.

Like numerals refer to like parts in the several views of the drawing.

This invention is adapted for application to any character of typewriter and in connection with any desired form of type bar, being here shown in Fig. 1 as assembled in a front strike machine, the frame 15 of which is provided with a segment or type support 16 and the type rest 17 with which the type bars 18 contact when not in use. These bars are controlled by any desired keyboard connections, such for instance, as the links 19 extended to the pivot levers 20 carried by the bracket 21, the opposite ends 22 of which levers are suitably connected at the keyboard. The type bars when in writing position contact with the platen 23.

In the application of the form of the invention shown in Fig. 1, the support or segment is provided with sockets 21 adapted to receive the retaining bolts 25 which are preferably of curved cross section in order to permit their rotative adjustment in their sockets. This bolt is provided with the head 26 which may be of any desired conformation, for instance, a rectangular plate, as shown in Fig. 3, and the shank of the bolt is provided with a circumferential holding face 27 formed in any preferred manner thereon, for instance by the oppositely inclined surfaces 28, as shown in Fig. 3. For the purpose of retaining this bolt in its socket and exerting pressure longitudinally thereof, a securing device, such as a screw 29 is disposed in the socket 30 which communicates with the socket 2 1 of the bolt intermediate of the ends thereof and at such an an gle relative to the longitudinal axis of the bolt socket as to effect a longitudinal movement of the bolt as the retaining device is fed inward.

Cooperating with the bolt just described is the type bar hanger 81, which in the form shown in Fig. 2 is provided with a lug 32 upon its front face having pintles or pivots at opposite sides thereof. The rear face of this hanger is formed with cooperating interlocking members, for instance, the mortise 34: formed by the flanges extending parallel. to the body of the hanger and spaced therefrom, so as to form. a way in which the plate 36 of the bolt may travel, while the angular formation of these provents oscillatory movement while permitting adjustment at an angle to the type bar pivot. The flanges 35 extend into the circumferential groove 39 at the rear of the plate 26. With the parts as assembled in Fig. 1 the longitudinal pressure upon the bolt draws the flanges 35 into firin contact with the outer face of the support thus clamping the parts in adjusted position. A desirable arrangement of a plurality of these hangers is shown in Fig. 1 where they are disposed in different parallel planes and secured in position by the screws which being disposed at an angle of substantially forty five degrees at the upper and lower portion of the support are easily accessible to permit the adjustment of the hanger either rotatably of the bolt or laterally thereof by simply loosening the screws while a partial removal of the screws permits the complete withdrawal of the parts.

Cooperating with the form of hanger shown in Fig. 2 is a form of type bar having a bifurcated pivoting end 86 in which the bearing cups 3? are threaded for adjustable mounting and carry the usual bearing balls 38 which contact with the ends 33 of the pivot carried by the lugs 32 of the hanger. This provides a bearing having only three points of contact which reduces the friction and wear to a minimum and by disposing the ball bearings in the bifurcated portion of the type bar the construction is materially economized and rendered more easy of production. in Figs. 4 and 5 a modified form is shown in which the flanges 35 of the hanger are disposed to permit a lateral adjustment upon the bolt parallel. with the type bar pivot.

In Fig. 7 a modified form of hanger 4L0 is shown cooperating with a similar construction of headed bolt to that shown in Fig. 1. This form of hanger is shown in detail in Fig. 9 and is adapted to cooperate with a type bar 41 having the-pivots 4:2 thereon, the side walls 43 of the hanger having threaded apertures 44, as shown in Fig. 9, adapted to receive the ball bearing caps 45, Fig. 7. In this form of hanger the mortise or interlocking connection -16 for the plate 26 is disposed vertically or at an angle to the vertical axis ofthe type bar in the hanger, and the flanges 17 forming the way for adjustable connection with the plate are adapted to be drawn into contact with the front face of the support 16 by means of the securing screws 29 engaging the face 27 upon the headed bolts 25, the same as described in connection with Fig. 1. This form pro vides for both a rotative adjustment of the bolt and the adjustment of the hanger laterally thereon at an angle to the type bar pivotz' Fig. 8 illustrates a modified form of bolt, shown in detail in Fig. 10 and adapted to cooperate with the form of hanger shown in Figs. 7 and 8. This bolt 48 is provided with a curved contact face 19 and disposed in the support or segment 16 having the sockets and 30, as shown in Fig. 1, the latter socket being adapted to receive the screw and the former bolt 1-8. This bolt is provided with a plate or head 50 and circumferential groove 53 adapted to cooperate with the mortise connection 4C6 forming a tenon and mortise for adjustment of the hanger upon the bolt.

in Fig. 11 a vertical section of the form of hanger illustrated in Fig. 9 is shown, the inner wall 51 of which is cut away upon a curved line extending at an angle to the pivot axis so as to provide a clearance for the end of the type bar beyond its pivot 19, and a solid upper wall-52 extending to the outer ed go of the hanger thus strengthening the bracket and preventing dust, dirt or erasings from entering the bearings thereof.

In Fig. 13 a further modified application of the bolt is s iown which cooperates with the hanger i0, as shown in Fig. 9, this bolt being specifically shown in detail in Fig. 14:. This bolt is mounted in a suitable socket 56 formed in the type support 57, said bolt being provided with an interiorly threaded recess adapted to receive the inner threaded end of the securing bolt 58 which is provided with a head adapted to bear against.

the rear face 60 of the support and thus exert a longitudinal tension upon the bolt. The bolt is also provided with a plate 61 adapted to seat in the mortise 16 and having a circumferential groove 62 into which the edges of the flanges 4:7 extend so as to form a positive connection between these parts.

The application and operation of the invention will be apparent from the foregoing description, and it will be seen that the type bar hangers may in an instant be readily adjusted upon their supports laterally of the retaining bolt and clamped in such adjustment by longitudinal pressure applied upon the bolt. This pressure is most effectually obtained by means of a screw or other device accessibly mounted in the support at such an angle to the bolt as to draw the same longitudinally of its socket by contact with the surface thereon, and when this surface is circumferential of the bolt a rotative ad,-

justment of the bolt may be secured.

The 1 a socket therein, a retaining bolt mounted in hanger is adapted for lateral adjustment said socket, a hanger adjustably mounted upon the bolt in order to secure the proper alinement of the parts and this may be either in a plane at an angle to or parallel with the type bar pivot as found most desirable in the positioning of the type bar upon its support or segment. The use of the T-slot in connection with the headed bolt permits the removal of the hanger and type bar from the segment without a removal of the bolt or its securing screw as it is only necessary to slightly remove this screw in order to permit a ready adjustment of the parts.

It will be obvious from the foregoing that various means may be used for exerting a longitudinal tension upon the bolt in order to draw the hanger into clamping contact with the face of its support and hold it at its adjustment upon the head of the bolt. It is also apparent that the character of screw may be varied as Well as the conformation of the interlocked or mortise connection between the bolt and hanger.

The bifurcated type bar having the ball bearings mounted thereon in connection with the pivot upon the hanger has been found very desirable and efficient in use 0bviating many ditliculties present in the re verse relation of these parts and materially economizing the manufacture, but the invention is not confined thereto.
