Application filed February 16, 1924. Serial No. 693,252.
M invention relates to t ewritin ma chines, and has for its object to provide new and improved supporting means or bearings for a rod or bar in such machines, and particularly for a paper finger rod.
To the above and other ends which will hereinafter appear, my invention consists in the features of construction, combinations of devices and arrangements of parts hereinafter described and particularly pointed out in the claims.
In the accompanying drawings which illustrate the preferred form of my invention,
Figure 1 is a fragmentary front elevation showing the platen carriage and paper finger rod of a No.60 Smith Premier typewriting machine embodying my invention.
Figure 2 is a fragmentary rear elevation of the right-hand end portion of the paper finger rod and its hearing or support.
Figure 8 is an enlarged sectional View taken on a plane represented by the section line 1-1 in Figure 1 and looking in the direction of the arrow at said line.
Figure d is a fragmentary end elevation of the right-hand bearing or support of the paper finger rod.
Figure 5 is an enlarged perspective view of a part hereinafter termed a washer member.
Figure 6 is a fragmentary perspective view showing an end portion of the paper linger rod.
Figure 7 is av fragmentary sectional view somewhat distorted for the purpose of bringing out more cleanly the function of the main feature of the invention.
The carriage or carriage frame of the No. ,60 Smith Premier typewriting machine comprises, as illustrated in Figure 1, a rear bar 1 from the end portions of which extend. forward in substantial parallelism end bars or socalled bosses 2. At their'tops the end bars 2 are provided with enlargements or lugs 3, the inner faces at whereof are machined or planed. The end bars 2 are illustrated. Co-operat-ive with the front face of the plat-en are one or more paper finger contrivances 6 which are adjustably or slidably supported on a rod or bar 7 arranged above and parallel with the platen, said rod or bar extending between the lugs 3 from which it is supported.
Heretofore, the paper finger rod has usually been directly secured by clamping or binding screws to the end bars of the carriage, and this has frequently resulted in the bowing or flexing of the rod owing to inequalities in construction and inaccuracies inevitable in manufacturing. The primary cause of the bowing has been due to the fact that in machining the inner facesl of the supporting lugs 3, it has not been possible always to maintain them at rightangles to the line taken by the axis of the rod when it is arranged in place. Moreover, the rods are not always exactly of the same lengths, nor is the distance between the faces 4- of the lugs always the same. The main object of my present invention is to obviate or provide against defects arising in the manner stated, and to this ,end I provide self-adjusting bearing members for co-operation with the end portions of the paper finger rod, and also provide for at will varying within limits the distance between the inner faces of the supports. In carrying out my invention in the present instance I provide an adjustable bearing piece or device for the right-hand end portion of the rod, said device being in the form of a bushing 8 that is threaded on its outer face and is provided with a hexagonal head or flange 9 to facilitate adjustments. The bushing is threaded into a tappedhole in the righthand lug 3, and the. inner face 10 of said bushing provides an adjustable face opposite to the fixed corresponding face l of the lefthand lug. The rod 7 is supported on headed screws 11 and 12,. the screw 11 passing through a hole in the bushing 8 and engaging in a topped opening 13 in the right-hand end portion of the rod, while the screw 12 passes inward through the left-hand lug 3 and engages in a tapped opening 14 in the lefthand end of the rod. (damped between the left-hand lug 3 and the head of the screw 12 is a shouldered collar 12 which comprises a support and bearing for a link 12 that is included. in the usual feed roll release mechanism of the machine. The head. of the right-hand screw 11 engages with the outer face of the hearing or bushing 8. Interposed between the ends of the rod 7 and its bearings are washer members 15. Each of the. pair of washer members or parts has a plain or flat outer face 16, the opposite inner face 17 being convex or ball-shaped and interseating with and matching a concave or cup-like socket or depression 18 in the inner face of the part or rod 7. The washers 15 are formed with holes or openings 19 through which the shanks of the respective securing means or screws 11 and 12 pass. The holes 19 are slightly greater in diameter than the shanks of the screws so as to afford some play or movement of the washers transversely of the screw axes. The righthand washer is housed in a depression or counter-sink 20 in the lug 3, the plane face of the washer engaging with the inner plane face 10 of the bushing 8. As most clearly shown in Figure 3, the rim 21 formed in the lug 3 by the depression 20 is provided with notches or grooves 22 diametrically opposite each other, the rear notch co-perating witha tongue or spline 23 projecting from the rod 7 at its rear side. groove connection between the rod and the carriage frame prevents the rod from rotating on its axis, thus providing a stable support for the paper fingers 6.
It will be understood that by turning the bushing 8 in or out, as may conveniently be done by a tool applied to its hexagonal head 9, the plane face 10 may be moved closer to or further from the corresponding opposite face 4t of the left-hand lug 3, this relative adjustment of the two faces taking care of any manufacturing inequality in spacing between the connected end bars and their lugs 3, and also of any inequality in the length of the paper finger rod itself. Furthermore, when the screws 11 and 12 are tightened, thus subjecting the rod to endwise pressure and binding or clamping it in place, the rod, the ball-faced washers 15 and the carriage frame will all be clamped together, the plane faces 16 of the washers will locate themselves flat against the associate flat or plane faces 4 and 10 of the supports, while the ball faces 17 and the socketed or concaved ends of the rod 7 willinterseat automatically, allowing the rod to ride on the faces 17 of the washers, without any bending or buckling effect. This co-action of the parts will be clearly apparent from 7 ,in whichthe inner face i of the left-hand lug 3 is shown faced off for purposes of illustration at an exaggerated angle. Nevertheless, it will be seenthat the plane face of the This tongue and washer will seat flatly against the face 4, the effect being to turn the washer to some extent relatively to the axis of the screw 12 without however preventing the rounded or ball-end of the washer from interseating properly as before with the concaved end or circular depression in the end of the paper finger rod. The rod is thus provided with self-adjusting end-bearings.
My improvements may be applied to'ex isting machines with slight and inexpensive changes yet with the result that prior defects of the replaced construction. are entirely eliminated. It is further to be understood that while my invention was more particularly designed for use in connection with a paper finger rod or bar, and has been specifically described in its application to such rods or bars, nevertheless the principle of the invention may be made use of in other parts of typewriting machines and in other relations, as well.
