MACHINERY FOR CONVERTING MOTION.

SPECIFICATION forming part of Letters Patent No. 275,436, dated April 10, 1883.

Application tiled February 21, 1883. (No model.)l

To all whom t may concern:

Be it known that I, JOHANN C. TAUBER, a citizen of the United States, residing at Plain City, county of Madison, and State of Ohio, have invented certain new and useful Improvements in Machinery for Converting VOscillat.`

use the same, referencev being had to the accompanying drawings, forming a part of the specication, the principle of the invention being herein explained and the best mode in which I have con'templatedapplying that principle, so as to distinguish it from other in-veutions.

In making this invention attention has been directed solely to'rmachinery formed without a dead-center, and which is actuated by the return-stroke as well as by the forward stroke of the oscillating device. ent in machinery adapted to operate without the possibility of stopping on a dead-point is obvious. The advantage possessed by machinery which is adapted to be actuated by both the forward and the return strokes of the oscillating device is that a very much lighter iiy-wheel may be used than otherwise would be possible. For in such instance the flywheel need be only of weight suflicient to generate momentum during one stroke` of the oscillating device to continue the movement ot' the driving parts during the instant of time when the stroke or vibration of the oscillating device is being changed from one direction to the opposite-direction.. This fact renders such machinery especially useful to jewelers, watchmakers, and other artisans, as it may be small in size and yet ample in speed and power. It can be placed on the work-bench and used i'n counter-shading, or it can be applied directly to the work. Such `machinery is of merit in connection with dentallathes and analogous portable mechanism, which require lightness of weight and compactness of yform as their requisites.

One controlling object in view in Vmaking this invention was to adapt` a machine. of the The advantage inherabove description so that it might be actuated by direct power as the oscillating device rocked in one direction, and might be actuated by secondary power as the oscillating device rocked in its opposite direction ot' movement. A second controlling object was to cause this intermittent direct power to wind up a motor simultaneously with imparting positive action to the driving parts, said motor being adapted to actuate the driving parts by its secondary power, and at the same time therewith to return the oscillating device into normal position for the nextrecurring application of the direct power.

' With these ends in view and to the attainment thereof my invention consists, first, in providing means whereby an oscillating device may he actuated by positive powerin one stroke, and may be actuated by secondary power in its opposite stroke; secondly, in providing means whereby an oscillating device may be actuated in one direction by direct power which simultaneously winds up a motor, the latter actuating the driving parts during the intervals of suspension of the direct power, and at the same time returning the oscillating device to its normal position for the next impulse of positive power.

In addition to these twomain principles of construction the invention consists of certain other matter hereinafterdescribed and claimed.

Referring to the drawings, Fignrel is aperspective view of one form ot' machinery embodying the invention. Fig. 2 is a sectional pian of the same. Fig. 3 is a perspective of a 'diiferentforin Fig. 4t is a vertical cross-section of said different form. Fig. 5 is a side elevation of another form of the same principle. Fig. 6 is a perspective of still another form of the invention. Fig. 7 is aperspective 'of an additional modification. Fig. Sis a detail view, representing a modification of the oscillating device. Fig. 9 represents another modification of the oscillating device. Fig. 10 represents a companion wheel provided with friction-clutches.

The form of machinery shown in the lirst two figures is constructed with an oscillating shaft, A, having a. spring-drum, B, made fast thereto, one end of the spring being secured to said drum or shaft, and the other end being fastened to the standard C. To the periphery of this spring-drain is secured a band, D, which depends downward and is adapted to be connected to a treadle, so that the machine can be driven by onefoot of the operator. Such treadle might be located beneath the work-bench on which the machine is placed; or the power may be derived from any suitable place, as a single wire cord, or its equivalent, may be intermittentlyv operated at a distance from the machine and transmit actuating-power to the latter very well. 0n the opposite extremities of the shaft are loosely mounted the two companion wheels E and F, the spring-drum being located between said wheels, and the latter being respectively provided with ratchetsa and b. Ratchet@ ot' wheel E operates to automatically connect the latter tothe shaft, soas to turn therewith, as the shaft has movement in a forward direction. When theshafthasmovementinrcversedirection,said ratchet a automatically disconnects wheel E from the shaft, and said wheel is thereby permitted to move independently of the sha-ft. Ratchet b of wheel F operates to automatically connect thelatter to theshaft while said shaft is moving on its return stroke, and to automatically disconnect wheel F from the shaft when the latter is moving on its forward stroke. A

driver, G, secured to a driving-shaft, H, is

adapted to be in constant engagement with both said wheels. Each wheel is thus maintained in constant rotation, inasmuch as when it is not operated by the oscillating device it rotates idly with the driver, and there is no inertia thereof to be overcome by the oscillating` device when the latter is again connected 1o said wheel. The driver is adapted to be actuated by wheel E when the latter is fast to the oscillating device, and when wheel Fis fast to the oscillating device the driver is actuated by said latter wheel, the two wheels E and F respectively engaging with the driver on opposite sides of its axis of rotation, there by causing the opposite rotary movements of said wheels to operate the driver in a constant rotary movement in a single direction. The driving-shaft carries a light fly-wheel, K, which need be only of such weight and size as to gain momentum sufficient, on one stroke of' the oscillating device, to continue the movement of' the driving-shaft during the instant of time in which said oscillating device is changing from its stroke in one direction to its reverse stroke. The driving-shaft may be provided with agraded series of pulleys, L. By intermittently drawing or pulling` out the band l) two results follow: the oscillating shaft is rocked forward and the spring-motor is wound up. Wheel E, being ratcheted fast to the oscillating shaft during this forward movement, is thereby positively rotated, and actuates driver G in a correspondingpositive rotation. Upon releasing the band from this direct power two results simultaneously take place: the recoil of the wound spring actuates the oscillating device in its return movement, so as to be in normal position for the next recurring application of direct power, and it also actuates wheel F, as the latter is then ratch'- cted fast to said oscillating device. Wheel F carries the driver G with it in rotation, and thus the latter is actuated by the secondary power of the motor during the interval ot suspension of positive power. In this manner the band is rewound on the spring-drum, and the driving parts maintained in steady rotation.

Reference now being had to the several modifications shown in the drawings, it willbe observed that in the f'orm of' machinery represented in Figs. 3 and 4 wheels M and N respectively correspond to wheels E and F ofthe machinery shown in the first two figures, wheel M being of greater diameter than wheel N and carrying a belt, 0, which operates the driving-shaft, said wheels being connected together by bevel-gear wheel I.

In the form of machinery shown in Fig. 5 wheels R and S correspond, respectively, to wheels E and F ofthe first two figures, wheel R being of greater diameter than wheel -S. A wheel,'l, connects the small companion wheel S with the large companion wheel by means of a pinion, V.

It will be observed that in each ot` the two forms of machinery last described the driving-shaft is parallel with the axis ofthe oscillating device, instead of being at right angles therewith, as in the form ot' machinery first described. In the machinery illustrated in Fig. 6 of the drawings, the spring-drum \V rocks freely on the iixed shaft, and the ratchets connect said drum directly to the two companion wheels.

I have shown in Fig. 7 a driving-sliat't, X,

IOO

on which are loosely mounted the two companion wheels c and d, said ,wheels being in constant mesh with wheel Y, made fast to the oscillating device. Companion wheel c is provided with apawl which engages with a ratchet rigid with the driving-shaft when the oscillat ing device turns in one direction, and when said oscillating device turns in its opposite direction a pawl ot` companion wheel d engages with a corresponding ratchet of the driving-shaft, each companion wheel turning` idly on the driving-shaft when its respective pawl is not engaged therewith, as described.

In Fig. 4 the oscillating shaft is represented as provided with two depending cords, instead of one depending cord or band and a springdrum. This is to illustrate one modified form of oscillating device, as a weight may be secured to one of the two cords and operate substantially in the same manner that' the spring does in the machinery first described.

Another modification ot'oscillatiug device is shown in Fig. 8, the rocleshaft being provided with a rigid arm, c, suiiiciently weighted to operate in substitution for a coil-spring or a weighted cord, as previously described.

IIO

A further modied form of oscillatingdevice is represented in Fig. 9, therock-shaft having pinion frigid therewith and meshing with a vertical rack-bar, g.

In each one of these three modi ticationsgravity would actuate the oscillating device in its reverse stroke. t c

In Fig. l0 a companion Awheel is represented as provided with'frictionclutches hin substitution for a pawl and ratchet.

The various modifications herein set forth are given to illustrate the breadth of t-he principle of my invention, and they should not be.

understoodas restricting said principle to the forms thus represented.

In substitution for any ratchet or friction clutch the companion wheels may be provided with appliances of a `different character, provided they are adapted to -automatically connect and disconnect saidcolmpanion-wheels to the operating parts, as previously set forth.

It is apparent that the oscillating device may.

be adapted to be returned in its reverse stroke by other means than those herein suggested. So, too, other forms of embodying and using the principle of my invention vmay be employed in substitution for4 any ot' the -forms I have herein shown. Itwill therefore be understood that omissions, substitutions, and changes may be made as regards the forms and partsherein set forth, provided the principles of construction and Voperation embraced in. the following claims are `retained and employed.
