Specification of Letters Patent.

The carrying mechanism is shown as applied to the machine of m co-pending application for patent Serial 0. 142,190, filed January 13, 1917 of which this is a divisional application, and reference is made thereto for such parts of the complete de- .vice as are non-essential to the present combination.

The invention consists in the novel construction and combinations of parts, as hereinafter set forth.

In the accompanying drawings, illustrating the invention, the numeral 4 designates the transversely shiftable carriage of a calculating machine, wherein are mounted, upon shaft 6, the wheels 5, whereon are registered the figures previously set up upon the keyboard of the machine. The registering wheels 5 are actuated, in the registering and carrylng operations, through the medium of intermediate gears 11, mounted upon shaft 12, toward and away from which gears the carrying shaft is rocked, as described in my hereinbefore mentioned application No. 142,190. g

The carrying shaft 9 is provided with a series of annular collars 42, each collar having guides 43 wherein works a'transversely slidable dogor tooth ,8, and having also a transversely extending pin 45, working in a slot 46 of the collar next adjacent thereto at one side, the collar 42 at one end of the series being fast to the shaft and all of the other collars having usually a frictional bind upon the shaft, to rotate therewith, but admitting of a movement of the collars with respect to the shaft against such frictional bind or resistance. The fast end collar and all of the other collars have each a pin and slot, as stated, and a'mem- ,ber 0, hereinafter described, at the end of the series opposite the fast end collar, has

a pin 45 only, and no slot and no dog or tooth. The dogs of all of the collars are arrangedspirally, entirely around the shaft in a single series.

Located between the intermediate gears 11 are reciprocatory carrying members 47 piv oted at 48, and having each an arm 49, normally extending in the path of a transverse pin 50 of a registering wheel 5, each registering wheel having a in 50, and said memher having an opposite y projectin I provided with a cam surface'52, adapted to arm 51,

extend within the path of movement of a carrying dog, there being one member 47 for each dog and for each registering wheel.

The cams 52 of the arms 51 are each double, having two inclined cam surfaces, one of which acts upon the dogs to move them endwise in the rotation of the carrying shaft clockwise, and the other oppositely inclined part acting to move the dog endwise in the reverse spiral arrangement, the dogs moving endwise in the same direction into active position, or alinement with the gears 11, in each case. The dogs are returned to normal position by springs 53 thereof (hearing at their left-hand ends, Fig. 1 against shoulders of the collars), and the pivoted carrying members are returned to normal position by radial projections or fingers 54 of the carrying shaft, said fingers following the dogs and having end cam surfaces 55, engaging said members, the cams 55 being double, having oppositely inclined parts, to return said members in either direction of rotation.

The radial fingers 5 4: are loosely mounted upon the carrying shaft, between the collars thereof, each tinge having a connection with the end of a pin 45 of the second collar therefrom at one side thereof, and being movable with said pin and collar, in the rearrangement to reverse spiral of the carrying dogs, to position at the opposite side of the carrying dog of the adjacent collar atv this side. The fingers, being moved to the opposite sides of the carrying dogs, are in position to return the carrying members e7 to normal position after said members have acted upon said dogs upon reverse movement of the carrying shaft.

Located between the intermediate gears are collars 56, carrying each a springpressed pin 57, said pin engaging either of two recesses 58 of the pivoted carrying members, to retain them in normal position and in position when thrown pivotally.

Means are provided to check the movement of the pin-a5 with the shaft 9 while the rearrangement of the carrying teeth to reverse spiral is being effected, and embodying also means for positively locking the series of collars, with the teeth thereof in.

spiral arrangement, including preferably a member a, fast upon the shaft and having a circumferential notch h, a cam member 0, loosely mounted upon the shaft and having a peripheral cut-away or reduced portion (Z, and a lever member 0, also loosely mounted upon the shaft and the body 6 of which is of a radius less than thatof the body of said cam member, said lever member being provided with a radial extension 7, having at its outer end a laterally offset head (1,

oi 'erlying the reduced portion of the cam member and having its outer surface lying within or registering w th a circle inscribed with the shaft as a center and a radius equal to the longer radius of the body of the cam member, said lever member having at one side a circumferential notch h, and at its opposite side an extension 2', )rovided with recesses or seats j, and a ridge is between the recesses.

A spring-pressed pin Z is carried by the cam member, said pin normally engaging one of the seats j of the lever member and working longitudinally ,within a recess or seat m of a larger pin or projection 45 of said member, said larger pin being one of the series of pins 45 and working within a slot %6 of the end collar 4-2 said pin 45 having an axial-reduced extension to which the return finger 54 of the collar 42" is connected.

The cam member carries a pawl p, intermediately pivoted at 1) and provided with a laterally extending tail. end 1], normally engaging the noteh b of the fast member, to lock the cam member to the shaft, said pawl having an inwardly extending head end 9', normally engaging the circumferential surface of the body ofthe lever member at the margin of the notch h.

In the reverse or counter-clockwise movement of the shaft, to rearrange the teeth or dogs of the collars to reverse spiral, the line of collars being locked in their spiral arrangement to the shaft by the engagement of the tail end a of the pawl 29 with the notch b of the fast member, the head 9 of the lever member will be first brought against a pivoted chcckr, carried by a bellcrank lever 59, forming part of the rocking means for the carrying shaft, to prevent further movement of the lever member with the shaft, the pin Z of the cam member then moving within the seat of the lever member and allowing a movement of the cam member with respect to the lever member sufiicient to cause the head of the pawl 79 to be brought opposite the lateral notch lb of the lever member, the pin then engaging the ridge 7c and resisting any further movement of the cam member with the shaft and with respect to the lever member, the fast member continuing to turn with the shaft and, by engagement of the beveled wall of the notch I) with the tail end 9 of the pawl p, pushing said tail end out of said notch and releasing the lock between the fast member a and the dog-carrying cam member (2, for holding the dogs or teeth of the collars in spiral relation.

The reverse movement of the shaft being continued, the fast end collar 42", all of the other collars l2 and the other end collar .42" will turn with the shaft, the pin 45 of the cam member being held from turning collar 42*, and will then check said collar 42 from further movement with the shaft,

said collar having moved a distance equal of said slot will be brought against the pin 45 of the collar 42", to prevent further movement with the shaft of said second J collar in line, said collar having moved with the shaft a distance equal to the combined length of two slots 46. This step by step or successive checking of the collars will follow, in the reverse movement of the shaft, throughout the line of collars, to the fast collar 42, which will, when the spiral re-' arrangement is' completed, have moved a distance equal to the sum of the length of all of the slots 46, the collarnext adjacent thereto a distance equal to the sum of'the length of all of the slots less the length of one slot, etc.

The collar 42 is madefast to the shaft by a pin 8 thereof, engaging a radial notch s of an extra collar 25, fast to the shaft.

The spiral rearrangement of the dogs or teeth of the collars being completed, the fast collar 42 will exert a strain upon the line of collars, to'rotate them all bodily with the shaft, this strain being sufficient to cause the spring-pressed pin Z to ride over the ridge is of the lever member, into engagement with" the other seat thereof, and in this movement of the cam member the lever member will. be checked against further movement with the shaft 'by engagement of the head 9 of its radial extension with-the device 4, thereby admitting of the engage- *ment of the free end of the check 1" with a lateral notch c of the cam member, said check being thereby thrown, by the beveled end wall of said notch, to position at the opposite side of said cam member, ready to engage the opposite side of said head, upon clockwise rotation of the carrying shaft,

circumferential surface of the body 6', at the opposite margin of the lateral notch h,

the cam memberbeing thereby again locked to the fast member and the series of collars being all positively locked in spiral relation.

In the clockwise movement of the operating handle, the same action takes place to check the movement of the pin 45 with the shaft 9 while rearrangement of the carrying teeth to reverse spiral is being accomplished; to release the lock holding the series of collars with the carrying teeth thereof in spiral relation, and to reengage said lock and atthe same time to release the check upon the movement of the pin 45 with said shaft.

In the case of the Reissue Patent No.

13,841, dated December 8, 1914, a check spring is provided for the collar at one end, said spring acting to prevent the rotation of the collar at one end until the rearrange- 'mentto reverse spiral is accomplished, and contmuing to check the rotation of the carrying shaftafter such rearrangement, and at all times,'but in the present case, after the rearrangement to reverse spiral and the loose collars having movable teeth or dogs,
