TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented March 26, 1907.

Application filed October 22, 1902. Serial No. 128,287.

To all whom, it meaty concern:

Be it known that I, ROBIE SEIDELINGER, a citizen of the United States, and resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

My invention relates to ribbon-feed mechanism for type-writing machines; and one of the main objects of the invention is to provide simple and eflicient mechanism of the character described for automatically reversing the direction of the feed of the ribbon when a given amount thereof is fed from one spool to another.

A further object of the invention is to pro vide simple and eflicient mechanism for automatically effecting a transverse as well as a longitudinal feed of the ribbon, so that every portion thereof may be used.

To the above and other ends, Which will hereinafter appear, my invention consists in the novel features of construction, arrangements of parts, and combinations of devices to be hereinafter described and claimed.

In the accompanying drawings, wherein like reference characters indicate corresponding parts in the various views, Figure 1 is a vertical central front-to-rear sectional view of one form of type-writing machine embodying my invention. Fig. 2 is a transverse sectional view of the same, the section being taken on the line :0 0c of Fig. 1 and looking in the direc tion of the arrow at said line. Fig. 3 is a fragmentary vertical front-to-rear sectional view of the machine, the section being taken on the line y y of Fig. 2 and looking in the direction of the arrow at said line. Fig. 4 is an enlarged detail fragmentary perspective view of a portion of the reversing mechanism to be hereinafter described.

I have illustrated my invention applied to an under-strike type-writing machine, though itshould be understood that for the purpose of my invention it is immaterial what character of writing-machine my invention is applied to.

The frame of the machine comprises a base 1, corner-posts 2, and a top plate 3, which latter supports a traverse-rod 4, that guides the carriage 5, in which a platen 6 is mounted to revolve.

The rear of the carriage is provided with rollers 7, that cooperate with the traverserod, whereas the front of the carriage carries alroller 8, that bears upon a track 9 of the top ate.

p Key-levers 10 are fulcrumed on a bar 11, projecting from the base 1, the forward end of each lever being provided with the usual finger-key 12, and a connecting rod or link 13 is interposed between each key-lever and its associated type-bar 14, whereas a restoringspring 15 is associated with each lever to assist in restoring it and the connected parts to their normal positions.

A universal bar 16 extends transversely beneath the various key-levers and is connected at its ends to upright links or rods 17, that are supported by their hooked ends on a transverse bar 18, connected to the rockerarm 19, secured to a rock-shaft 20, that carries an upright rocker-arm 21, provided with feed-dogs 22, which cooperate with the feedrack 23, connected to the carriage. A spring 24 is connected at one end to the rock-shaft 20, and at its other end bears upon a fixed bracket-plate 25, so that the tension of the spring is exerted to restore the rock-shaft and the parts connected thereto to the position shown in Fig. 1. The carriage is connected by a band to a spring-drum, so as to move the carriage a letter-space distance in the direction of its feed at each actuation of a finger-key.

So much of the mechanism as has thus far been described constitutes portions of a wellknown type-writing machine, and further detail description thereof is considered unnecessar A The ribbon 27 passes from a ribbon-spool 29 at one side of the machine to a ribbonspool 30 at the other side thereof, whereas the intermediate length of ribbon between the spools passes through slots in the top plate, over the top plate and type-well of the machine, and between the types and the platen in the usual manner.

Each of the ribbon- spools 29 and 30 is splined upon an associated ribbon-spool shaft 31, which extends fore and aft of the machine and is supported in bearings 32, depending from the top plate of the machine, so that each spool is free to move longitudinally on its shaft, but by reason of the splined connection therewith is caused to rotate with its shaft. Each shaft 31 extends rearwardly of the rear bearing 32 therefor and is provided with a pulley 33 and a bevelgear 34, both of which are fixed to the shaft.

A driving-shaft 35 extends transversely of the machine and carries bevel-pinions 36 and 37 at the ends thereof, and the length of this shaft is such that when one of the pinions thereon is in mesh with its associated bevelgear 34 the opposite pinion on the shaft will be out of mesh with its associated bevel-gear, as represented in Fig. 2. The shaft 35 is supported in bearings 38 and 38*, that depend from the top plate of the machine and in which the shaft is adapted to slide longitudinally. The bearing 38 is bifurcated for the reception of a bevel-gear 39, which is mounted on the shaft and has a pin 40 that extends through a collar on the gear and into a splined groove 41 in the shaft, so that this gear is adapted to remain fixed with relation to the longitudinal movement of the shaft 35, but is connected to rotate therewith. The bevel-gear 39 has peripheral ratchetteeth 42, with which a spring-detent 43 cooperates, the detent being secured by a screw 44 to the bearing 38, thus preventing a backward rotation of the driving-shaft. The bevelgear 39 meshes with a companion bevel driving-gear 45, which is secured. to or forms part of a ratchet-wheel 46, that is mounted on the same center as the spring-drum 47. The spring-drum has a pawl 48 pivoted thereto at 49, and thenose of the pawl is maintained in engagement with the teeth of the ratchet-wheel 46 by a spring 50, that is secured to the pawl and bears at its free end against a pin 51, carried by the drum. The drum 47 has secured thereto at 52 one end of a band 53, the other end of said band being secured to the carriage at 54, so that the tension of the spring is exerted. to effect astepby-step feed movement of the carriage during the actuation of the key-levers.

An angular bracket 55 is secured by a screw 56 to the base 1 of the machine, and the upright arm of the bracket receives a headed screw-pivot 57 of an upright lever 58, the upper end of said lever being received within a peripheral groove or depression. 59 in the driving-shaft 35, whereas the lower end of said lever carries a laterally-projecting pin 60, that is received within an apertured portion 61 of a frame or lever 62, the latter being pivoted at 63 to an auxiliary bracket 64, that is secured by screws 65 to the angular bracket 55. The upper portion of the frame 62 is in the form of a yoke, the two arms 66 of which are apertured at diametrically opposite points, as indicated at 67, (see Fig. 1,) and these apertures receive a band, cord, chain, or ligament 68, which extends freely therethrough and each end of which is secured to one of the pulleys 33. I prefer to make the part 68 in the form of a fine chain or other flexible ligament in which there is little give or stretch, though it should be understood that any suitable flexible connection may be used, and the term band employed in the claims is intended to designate generically any suitable ligament, whether it he a chain, cord, or other line connection.

Secured by a screw 69 to the rear side of the upright arm of the bracket 55 is a spring 70, which is bent at its free end 71 for cooperat'ion with a cam 72 on the rear face of the lever 58. The purpose of this spring and its cooperating cam is to insure a complete movement of the lever 58 and the parts eontrolled thereby when the cam is moved to either side of the terminal 71 of the spring 70. The spring will when the highest por tion of the cam passes its end. 71 bearupon a side of the cam and assist or insur a complete movement of the lever and will likewise quicken the action of the parts, as will hereinafter more clearly appear.

The groove 59 in the shaft 35 is wider than the end of the lever 58. When the abutment 87 first engages an arm 66, the lever 58 is moved a certain distance without moving the shaft 35 at all while the end 71 of the spring 7 is riding upward on one of the faces of the cam 72. When said end 71 of the spring passes over the top of the cam 72, said spring completes the motion of the lever 58 quickly, thus instantaneously throwing one of the pinions 36 or 37 out of engagement with its gear 34 and the other of said pinions into engagement with. its gear 34.

The driving-shaft 35 carries an eccentric 73, which. is provided with a collar 7 4, through which. a set-screw 75 projects, the end of said set-screw bearing against the driving-shaft to rigidly connect the eccentric thereto. A strap 76 surrounds the eecentric and has a depending link 77, the lower end of which is pivoted at 78 to a crank-arm 79, that projects rearwardly from a rock-shaft 80, that extends transversely of the machine and is seated in suitable bearings in the sides of the base.

Projecting upwardly from the rock-shaft 80, near each end thereof, is a crank-arm :4 pivoted at its upper end 82 to a link 83, that in turn is pivoted at 84 to a yoke 85, the side arms 86 of said yoke passing on the outer sides of the flanges of the associated. ribbon-spool a'ndbeing perforated at the upper ends, where they are received on the associated ribbonspool shaft 31. It will be understood that the connection on both sides of the machine between the ribbon-spools and the rockshaft are the same, so that a rocking of the shaft 80 will cause both spools to be moved axially or along their shafts 31 to a. corresponding extent to effect a widthwise or transverse feed of the ribbon.

From the foregoing description it will be lOO seen, especially by reference to Fig. 2, that a movement of the carriage 5 from left to right will merely result in turnin the springdrum 47 without transmitting motion to the ratchet-wheel 46, and every portion of the ribbon mechanism will at this time remain in a state of rest. When, however, the carriage is fed in the usual manner from right to left, motion will be transmitted by the spring-drum through the pawl 48 to the ratchet-wheel 46. The eflect of this movement is to turn the bevel or driving gear 45, thus rotating its associated pinion 39 and transmitting a rotary motion to the drivingshaft 35. This rotation of the driving-shaft will turn the bevel-gear 34, with which. the pinion 36 or 37 is in mesh, the pinion in mesh depending on the longitudinal position of the driving-shaft. If, for instance, the pinion 37 is in mesh with its companion bevel-gear 34, then the left-hand ribbon-spool will be positively driven by the rock-shaft, and the ribbon 27 will be moved in the direction of the arrows adjacent to the ribbon in Fig. 2, and the various parts will be disposed as shown in said figure. The continued rotation of the left-hand ribbon-spool shaft 31 will continue until an abutment 87 to the right of the frame 62 is brought to bear against the right-hand arm 66 of said frame, when the frame Will be shifted around its pivot 63 toward the left. This movement is transmitted through the pin-and-slot connection 60 61 to the lever 58, the upper end of which is vibrated toward the right, thereby moving the driving-shaft 35 longitudinally toward the right until the pinion 36 thereon is thrown into mesh with the companion bevel-gear 34 of the right-hand ribhon-spool. This movement of the shaft 35 effects a disengagement of the pinion 37 from the gear of the lefthand ribbon-spool, and it becomes disconnected from the drivingshaft, and the reversal in the longitudinal direction of the feed of the ribbon is thus brought about. The ribbon continues to wind on the right-hand ribbon-spool until the knot or abutment 87 on the band 68 is brought into contact with the left-hand arm or frame 62, and a continued movement of the band results in the frame being shifted toward the right around its pivot 63 to the position indicated in Fig. 2, which shows the positions of the parts just after the driving-shaft has been moved to the left. This movement is transmitted to the lever 58 to eflect a longitudinal movement of the drivingshaft 35, so as to disengage the pinion 36 from the gear of the righthand spool and to throw the pinion 37 on said shaft into mesh with the gear of the left-hand ribbon-spool, and so on, this action is repeated to automatically reverse the direction of longitu of the band 68 passes from one pulley to the other.

Upon reference to Fig. 2 it will be seen that the core a of each ribbon-spool, which is shown in dotted lines, is much larger than the core I) of the pulley, which is likewise shown in dotted lines in this figure. It follows, therefore, that the surface speed of the core of the ribbon-spool is much greater than that of the pulley, though each associated pulley and ribbon-spool are mounted on the same shaft and rotate together. This construction permits a ribbon of any desired length to be employed and at the same time enables a comparatively short extent of band 68 to be used. Thus, for instance, a ribbon of, say, five yards or more in length may be employed, whereas the band may be less than a yard in length, and by making the abutments 87 adjustable on the band an automatic reversal in the longitudinal feed of the ribbon can be effected at any desired point in the movement thereof or at any pre determined point from the end of the ribbon. These abutments 87 may be of any desired construction such, for instance, as a mere split ring which is clamped in place upon the band. It will be-understood, therefore, that the machine may accommodate any desired length of ribbon, and by properly setting the stops or abutments 87 the direction of feed of the ribbon may be changed automatically as an end thereof is approached. It will likewise be seen that by this construction there is no strain whatever exerted upon the ribbon itself to effect a reversal in the direction of its feed, that the mechanism for auto matically effecting a change in the feed is brought about by mechanism which is entirely independent of the ribbon and which is actuated by the power employed to propel the carriage. Thus, for instance, the spring drum transmits motion to the pulleys, and the band as it is taken up by one pulley will eventually cause the abutment on the band to be brought into contact with the shifting device 62, thereby changing the longitudinal position of the driving-shaft 35 and throwing it out of operative connection with one ribbon-spool and into operative connection with the other.

Upon reference to Fig. 2 it will be seen that the pivotal connection 78 between the crank-arm 79 and the link 77 is such that the eccentric 73, strap 7 6, and link 77 maybe moved with the shaft during the longitudinal movement thereof without in any way affecting the operation of the connections between IIO the driving-shaft 35 and the rock-shaft 80.

The intermittent rotation transmitted to the driving-shaft 35 during the feed movement of the carriage causes the eccentrics 73 to effect an intermittent vibration of the rock-shaft dinal feed of the ribbon when a given extent l 80 in opposite directions, so that the cranknubarms 81 are moved step by step first toward the front and then toward the rear of the machine, and these movements of the crankarms are transmitted to the yokes S5 to cause the ribbon-spools to be moved longitudinally on their shafts 31, so that during an actuation of the machine the ribbon will be automatically-fed widthwise, as well as longitudinally, and automatically reversed in both directions to use the entire surface 01 the ribbon.

Various changes may be made without departing from the spirit of my invention, and certain features may be employed. without the others.
