MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 409,082, dated August 13, 1889.

i Application iiled September 28, 1888. Serial No. 286,681. (lIo model.)

To all whom it may concern,-

Be it known that I, ROBERT WEHRLE, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Mechanical Movements for Rock-Fans, dac., of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this speciiication.

This invention relates to a mechanical movement especially devised for actuating the rockfans which, with their adjustable connecting devices, are the subject-matter of another application, Serial No. 286,682, of even date herewith, but may also be used for operating washing-machines, churns, ne.; and the invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is avertical section and shows the 4works of the movement and the pulley-weight that operates it. Fig. II is a side view of the works in elevation. Fig. III is an enlarged section taken on line III III, Fig. I, and shows .the sliding'cutoff dog that locks the escapement-Wheel between its pulsations. Fig. IV is an enlarged View of the cross-head or anchor of the adjustable pulsating bar that carries the detent which engages with the escapement-wheel. Fig. V is an enlarged view of the bottom section of the sectional actuatingweight aud shows the screw-nut engaged on the bottom of the weight-rod and seated in a countersink in said section of the weight.

Fig. VI is an enlarged transverse section taken on line VI VI, Fig. VII, and shows the tubular peripheral head-bearing of the rock-shaft that carries the cross-head ofthe pulsating bar; and Fig. VII is an end view of the same. Fig. VIII is an enlarged section taken on the line VIII VIII, Fig. I.

Referring to the drawings, in which similar figures of reference indicate like parts in all the views, l represents the back plate, and 2 the front plate, of the case that boxes in the Works of the movement. 3 are the pedestals that connect said plates; 4, the screw-heads of said pedestals; 5, the screw-.nuts that engage thereon and hold the plates together in their relative positions, and 6 are the screws by which the case is held to one of the walls of the cupboard or room to which it is attached.

7 represents the drum shaft or axle that carries the drum 8, around which is wound the actuating-cord 9 of the operating-weight lO. The said shaft has its bearings 1l relatively in the rear and front plates of the boxing, and said shaft is extended in front beyond the plate and squared to form the keyseat l2, by which the cord is Wound around the drum and the weight elevated. The cord passes up from the drum around twin pulleys I3, Whose trunnions 14E have bearings Within the pendent arms l5 of the brackets I6, which are securedby screw-bolts 17 to the ceiling lSof the cupboard or room in which the mechanical movement is erected.

The operating-weight lO is of novel construction, being of adjustable weight, so as to be conformed to the power required contingent on the number and size of the fans to-be actuated, or other machines-as for washing, churning, pumping, zc-for which it may be used as a mechanical motor in the operationv of the same.

The fast end of the cord is secured to the drum, around which it is Wound by any suitable means, and its loose or reverse end is spliced or otherwise secured to the eyeletloop 19 of the weight-carrier rod 20, and a screw-nut 2l is secured onto t-he screw-terminal of said carrier-rod. A series of sectional weights 22, (see Figs. I and V,) provided with slots or cut-aways 23, provide the means for adjusting the weight to accord with the power that it is required to use. The slots in the side of the sections are cut in to a little past the center, and thus provide the means for seating said weight-s on the pendent carrier-rod, they being placed thereonA in the same way as the detachable weights of platform-scales. A countersink 24 is formed in the bottom of one of the sectional weights of sufcient size to receive the nut 2l, and, thai section heilig the iirst one placed on the rod, the nut is seated within said countersink. (See Fig. V.) l

The main drive-geared wheel 25 has tight bearings on the drum-shaft 7, and next said drive-wheel, also with tight bearings on the same shaft, is the ratchet-wheel 26. The dogpawl 27 has pivotal connection with one of the radial arms 28 of the drive-wheel by the bolt 29, which has its perforate seat in the IOO dog and in said arm of the drive-wheel, and a spring 30, secured by a pivot-pin 31 to another arm 28 of the drive-wheel, presses against and enforces the engagement of the dog-pawl with the ratehetwheel. As the weight is wound up from the winding of the cord around the drum by the action of the key, the dog-pawl acts as a follower, jumping the ratchetfteeth; but immediately that t-he ratchet-wheel ceases to t-nrn the spring impels the dog-pawl to engagement with the ratchet-teeth to hold the weight in its wound position, subject alone to its gradual unwind under the operation of its escapement devices while effecting the work that it is set to perform.

The drive-wheel is provided with cogs 32 around its periphery, that mesh into engage-A A axle has loose bearings 36 relatively in the rear and front plates 1 and 2, that box in the works of the movement. The cogs 33 of said secondary drive-wheel also mesh into engagement with the cogs 37 of the pinion 38, which pinion has tight bearings on the shaft 3S), 011 which shaft is also seated with tight bearings the escapement-wheel 40. The said escapement has the usual ratchet teeth 41 around its periphery, in which engages the detent 42 of the pulsating or pendulum bar 43, that regulates the pulsations of the escapement. The said detent is secured between the vertical members 44 of the compound angle-arms of the crosshead 45 by screw-bolts 46, that engage in their screwseats in said arms and pass through said detent and through the re-enforcing spring 47, that backs up said detent, and yet allows elastic movement of the same within the limit of said vertical arms.

4S is an anti-rattler cushion located between the detent and the inner vertical arm 44, and which is held in its seat by the same bolts that secure the detent and its spring.

49 are the horizontal members of the anglearms of the cross-head, that are coupled together by the set-screw bolt 50, which bolt also passes through the elongated slot 51 in the buffer-bar 52, which butter-bar is adjustable t0 lilnit the action of the toggle-link 53, which is pivoted to the projecting lug 54 by the bolt 55, which has loose bearings in one end of the toggle-link and in said lug. A spur-lug 5G, (that rises from the same end of said toggle-link,) when it bumps against said buffenbar, limits the movement of the link in that direction. It will be seen that the elongated slot in the bufferbar provides means of adjustment of said bar by its elongated transposition when the setscrew 5() is loosened.

The rear journal of the shaft 57, on which the cross-head of the pulsating or pendulum bar has tight bearings or is fast, has a loose bearing 58 in the rear plate of the caso that incloscs the works, and around the front j ournal 59 of said shaft is a screw-threaded boss GO, secured in rear of the front plate. A peripheral bearing G1 is provided for said front journal by the tubular journal-box 62, whose peripheral screw-thread (i3 engages in its screw-seat 64 in the front plate 2 and in the boss of the case that ineloses the works, and its square head 65 provides a hold for the wrench or key that screws it home in its seat. It will be seen that by the provision of this screw-adjustable journal-box the end wear of the journals of the shaft is taken up, and thus the bearings of the pulsating detent of the escapeinent are readily adj usted. A screw-threaded duct 6b' through the head of said journal-box into its tubular bearing provides the means for lubricating said bearing, and the screw-threaded stop-pin (i7 closes the mouth of the duct after the insertion of the lubricant by being screwedtherein.

The pulsating or pendulum bar 43 below its cross-head is pivotally secured to the conter of the adjustable coupling-yoke 68 by the bolt 69, which passes through the perforated end of said pulsating bar, a perforation in the center of said yoke, and the perforated upper end of the counterpoise pendent bar 70, which latter bar carries the counterpoiseweight 71, that may be provided with a slot 72, that enables it to run on said bar, and is adjustably located and secured thereon by the set-screw 73. Near each end of the yoke is provided a curvilinear slot 74, and' relatively in both the pulsating bar and counterpoise-bar, and passing through said curvilinear slots of the yoke, thumb set-screws are seated, and when said bars are rightly adjusted in their relative pendent lines by screwing home said thumb-screws their adjusted position is set.

76 represents a compound lever, whose sot end has loose bearings on the pivot-pin 77, which pin is seated in and projects from the adjustable bed-plate 78. The bed-plate is secured to the rear plate thatincioses the works by the set-screw 79, which passes through an elongated slot 80 in said bed-plate and is engaged in its screw-seat in said rear plate. A set-screw 81, which is screw seated in a iianged projection of the said rear plate, is conformably set to any change of adjustment of the bed-plate, (as a take-up, consequent on the wear of the pulsating correspondents of the escapement.)

The said adjustment is effected by loosening the set-screw 7 9, that passes through the IOO IIO

in the corner pedestals 85 of theiiange guideplates and engage in their screw-seats S6 in said rear plate. A sliding bed-plate S7, that carries the surmounting arm 91, to which is secured the detent-dog 92, (that is the coadj utant detent of that which is spring-seated within the parallel angle-arms of the pulsating cross-head 45,) works longitudinally on the track-flanges 93 of the guideplates S2, whose surmounting flanges hold said bedplate in its seat under the impulse of the lever 76, in which the pivot-pin 8S (that surmounts and is carried by said sliding bedplate) has loose bearings in the ovate slot 39 in said lever.

The loose or operating end of the compound lever 76 is pivotally connected to the outer end of the aforesaid toggle-link 53 by the pivot-pin 90, and thus corresponding simultaneous action is maintained between the two escapement-detents 43 and 92. The detentdog 92 is provided with a stiffening-plate 94, between which detent and plate is placed an anti-rattler cushion 95, of rubber, leather, or other suitable material, that, as does the similar anti-rattler cushion 48 of its coadjutant detent, (being anon-conductor of sound,) deadens the rattling tick of the escapement. A set-screw 96, that passes through the adjustment-slot 97 in the said detent, anti-rattler, and stiffening-plate, is secured in its screwseat 96 in the arm 91, that carries said detentdog, and thus the detent is fastened to its adjustifient.

A curvilinear spring 99 engages in its perforate seat 100 in the projecting end of the pivot-pin 77, that carries the compound lever 76, and its stayed end engages with one of the pedestals 3, that hold the case together, and its operative end exerts a reactionary pressure against the pivot-pin 83, and thus re-enforces the back-throw of the compound lever ready for a renewed pulsation.

lOl represents oiling pipes or tubes, and 102 receiving -cups at their mouths. The said pipes carry the lubricant to the journal-bearings, respectively, of the drum shaft or axle 7, the axle 35 of the secondary drive-wheel 34, and the axle 39 of the escapement-wheel 40.

The running time for the one winding of the movement in rooms with twelve-foot ceilings is from nine to ten hours.
