i i Application led September 29, 1925. `Serial No. 59,303.

This invention relates to improvements in a mechanical means for transmitting power, the principal object being to transorm a rotary motion into a reciprocatory one and to extend the reciprocation indefinitely.

A further object is to provide a mechanism utilizing cooperating racks that mesh with block encased gear wheels, such blocks and racks being interrelated in a train;

To .the accomplishment of these and related objects7 my invention resides in the construction, combination and arrangement of parts as shall be hereinafter more fully described, illustrated inthe accompanying drawings and (pointed out in the claiu'is hereunto appende i The invention` can be most clearly de scribed and most readily understood when reference is had tothe accompanying illustrations of the `preferred (,:onstruction in which:

Fig.1 is an elevation of the train of gear carrying blocks and racks, part being shown Si in section;

Fig. 2 is a fragmentary plan;

Fi 3 and 4 are elevations ot the rack and lsock reciprocating mechanism.`

Fig.5 is an alternative form of recipro- 8 eating mechanism;

Figs. 6 and 7 are vertical and horizontal sections respectively, as taken on lines 6 6 and 7-7 of Fig. l; and

Fig. 8 is a section through `the lower rack y and supporting track.

" `In this invention for thetransforming of rotary motion into reciprocatory and the unlimited extension of the reciprocations, I em-` ploy gear wheels encased in blocks or car` n riagesthat are connected in a train by racks,

meshing with the gearr'wheels, that are also mounted on the blocks. y

of interconnected blocks `are arranged in alignment and all ride on amain' rack, mesh-` ing with the gears, thatis reciprocated. The first block in the series carries no rack but the encasedgear meshes With the rack from the second block Whose enclosed gear receives inturn the rack mounted on the third block and so on.

The mechanism producing the reciprocations of the train of gear blocks and of the main rack which are opposed, differs depending on the nature of the source of 5I power: If rotary, a shaftwith collars riding The series or train on reversed threads is used and the shaft oscillated by a segmental crown gear acting on a pair ot spaced pinions keyed to the ifar end of the threaded shaftcrit reciprocatory andv paralleling the train, by fixed or rigid and pivoted lever arms that-connect respectively with the end gear block and main rack.

Referring more xparticularly to the drawings wherein like characters indicate like parts throughout the several views, 10is a suitable base ou which a trackll is positioned to support a rack 13 that is adapted toV reciprocate horizontally.' A number of blocks 14 straddle this rack within each of which is enclosed a gear wheel 15 that meshes with the rack 13 andrides thereon supporting the block in this Way. A- channel 16xis cut through the blocks near thetop from end to end and is so disposed with relation to the enclosed gear that a rack member 17 dei signed to pass therethrough may contact with the said gear.

The rack 17 is carried by that block 14 immediatelybehind the block encasing the gear Wheel Withwhich it contacts and is ap-4 plied to the block by fastenings 18 on each side, Athe rack piece being bifurcated and formed to laterally engage both. sides ot the blockfas shall be more fully described.

f It Will thus be seen that the train of inter-` connected blocks 14 and the main rack 1.3 are both adapted to reciprocate horizontally and so the maximum ot efficiency is to be ob tained from this mechanism by causing these parts to recxprocatefin opposite directlons.

Toaccomplish this I provide a shaft 19 an fend of which is threaded lett for a space and then threaded right asl at 20a and 2Gb respectively and to these reverscthreads are applied collars 21 and QZffrom the former of which a standard extends to connect with the reciprocable rack 13 `while an arm spaced from and paralleling the axis of theA latter is fixed to the block 14 on the near end of the train. The end of the shaft' remote from the threads carries a pair oi'ispaced pinions Q3 vthat mesh Withopposite sides ofthe-same face of a segmental crown gear 24 supplying the power in this instance. The crown however is" toothed through `less than ahitlf of its circumference so that on turning 0pposite rotations are imparted to thel shaft 19 byV its meshing with first onepinion and then the other. At suitable locations throughout its length the shaft i is supported by bearings 25 on standards 26. a Asie obvious this type of reciprocating mechanism-"can only lie-employed when the power is being supplied in the rotary i'orm,`

I have included a modification to operate the device when a reciprocating source is to be utilized. This, as shown in ig.- 5, comprises,

a shaft 27 reciprocating in a plane parallel -With theV transmission, a rigid arm 28 tlierefrom fixed Ato theend blockll anda' cen- ,trallyzpivoted lever 29 connected to theend of the main rack 13, the pivoted connection on each end thereof including a pintle rei5 eeiving slot. i f i The racks 13 and k17 to which reference is made in the precedin Will preferably be in A the form ol channels ctween whose upright sides little rollers 30 are arranged transy versely. i y

f In the case of the rack members 17 the base of the channel is partially removed to form a fork, that bridges the block to which it is applied and fastened thereto as described. z5 The lower orniainrack, havingr toreciprofcate `on the track 11 is recessed to receive the .i vsame .by haviiigtlie bottom of'` the ,channels raised between f the arms thusuforming a t, double thickness of. side for a part `thereof' and then havingthe lowermost edges bent inwardly andksecurely and snugly embracing the rail. Friction is reduced by the insertionof roller bearings lvbetween the underside ofthe channel base andfthe` track.V i In operation7 when the required number of gear carrying blocks or elements have been i .arranged in line and means for oppositely reciprocating the blocks and main rack'liave been connected, the endblock, remote from iexthati'receiving the reeiprocations is moved backand dbi-th a` distance proportionate to4 but'many times greater than the first block i e. g., if the firsty block is advanced one inch andthe mainirackimoved the same distance ein the oppositedirection, Athe second gear blockis advanced" three 'inches the third sixy `inclfiesjand so on for it `will befobserved that., if the'inainrack' was fixed and the first block Y vvadvanced one inch the second block would 5U .move a; like distance without the action of the gear and rack but with Vthis the ygear is rotatedrby contact with the fixed lower rack and this rotationadvauces the rack member `.fixed tothe second block therebyiidrawing GCN-the said :block upfanotliei-yinch, making a` 'total ,of two' inches: The ratio being as a nrizif) :2(2a) :2(4a) etc.; while the opfposite reciprocation of the main rack still xfurtlier` advances the blocks, excepting the first, ingthe proportion of b :2b 3b etc. This movement in like increasing relation is trans- 1 mitted to each successive block element api pliedto; thetrain so that the multiplying of @,m themovenient may be carried outl to any de sired extent,

From the foregoingdescription taken in connection with the accompanying drawings, it will be manifest that amechanical means for transmitting power is.- provided ywhich Will-fulfillall the necessary requirements of such a device, but as many changes could be madein `the abovedescription and many apparently widely ydifferent embodiments of my invention constructed within the scope of' the appended claims without departing `from the spirit or scope thereof, it is intend- Aed that all. matters contained in the said accompanying specification and drawings shall be interpreted as illust ative and not in la limited sense.
