SPECIFICATION forming part of Letters Patent No. 4&4908, dated January 20, 1891. Application filed July 24, 1890- Serial No. 359,802. (No model.)

To all whom it may concern:

Be it known that I, ELI S. REED, a citizen of the United States, residingat Chattanooga,

in the county of Hamilton and State of Ten- I useful for actuating other kinds of machinery.

The object of the invention is to provide a simple,cheap,light, and efficientspring-motor which will consist of as few parts as possible, may be easily wound up with the expenditure of atrifling amount of power, may be readily and speedily applied to any kind of a sewing or other machine, may be quickly stopped or started, and which will conform in the highest possible degree to the multitude of requirements exacted of a motor of this kind.

One principal object of the invention is to diminish the friction to the lowest minimum.

The invention therefore consists, essentially, in the construction, arrangement, and

0 combination of parts, substantially as will be hereinafter described and claimed.

In the accompanying drawings, illustrating my invention, Figure l is a side elevation of my improved spring-motor. Fig. 2 is a bottom plan view of the same. Fig. 3 is a vertical longitudinal section of the motor. Fig. 4B is a detail plan view of the bottom part of the frame removed from the parts with which it connects. Fig. 5 is a top plan view of the horizontal bevel-gear which forms part of the winding devices. Fig. 6 is a vertical section of the winding friction-wheel and its integral tube, together with the sleeve which surrounds the latter. Fig. 7 is a bottom end View of the same. Fig. 8 is an end elevation.

is a detail plan of the perforated cover-plate which is used in connection with the wind ing-handle to keep the clutch mechanism within said handle in proper position. Fig.

11 is a detail plan view of the end portion of the winding-handle, the cover-plate shown in Fig. 10 being removed and the clutch mechanism being exposed to view. Fig. 12 is a sectional side elevation of my improved springmotor similar to 1, and showing certain of the driving-Wheels reversed in position, so that the driven machine may be operated in a reverse direction.

Similar letters of reference designate corresponding parts throughout all the different figures of the drawings.

A denotes the horizontal table of a sewing or other machine with which it is desired to use the motor. This may be any kind of a table belonging to any kind of a machine. My purpose is to locate my motor directly beneath the table, securing it thereto, so that it may be out of the way and may occupy as small a space as possible.

The frame of my improved spring-motor is secured to the under side of the machine-table A, and consists, preferably, of the follow ing parts arranged in the following manner, so that the several mechanical parts constituting the motor may be conveniently arranged in connection therewith, and so that all the needed adjustments for perfecting the operation of the motor may be easily and readily accomplished. At the left-hand end of this frame are the parallel vertical bars B B, (see Fig. 1,) placed asuitable distance apart and provided at their upper ends with slotted flanges, (see Fig. 2,) through which pass securing-screws or Other devices, by means of which said upright bars are firmly connected 0 to the under surface of the machine-table. The slots in the said flanges permit a slight lateral adjustment of these uprights, which can be easily accomplished at any time by loosening the attaching-screws, adjusting the bars, and then tightening the screws again. Connected to the lower endsot' these uprights or made integral therewith is a transverse horizontal bottom bar 13. (See Figs. 2 and 3.)

O O denote another pair of parallel uptoo rights similar to the uprights B B, at a suitable distance from said uprights B 13, near the middle of the motor-frame, and similarly connected at their upper ends by means of screws or other suitable attaching devices, as shown, to the under surface of the machinetable A. The lower ends of the uprights C C are connected together by means of the transverse horizontal bottom bar (1*, which bar is made integral with the longitudinal horizontal bottom bar or plate The end of the longitudinal part C nearest to the transverse bar B is designated by the reference letter 0 and is formed suitably to permit it to pass between parallel lugs or flanges form ed on the under side of said bar B. The end 0 is also provided with a couple of slots, through which pass screws that enter the under side of bar B. (See Figs. 2 and 4-.) Thus the end 0 is adjustable endwise beneath the bar 3', and in consequence the longitudinal part (J and its integral transverse part 0 are adjustable. The end 0 is further provided with a nut or internally-screw-threaded box made integral with the under side thereof and receiving one end of a set-screw q, the other end of which passes through a perforation in the flange on the edge of the bar B. By adjusting this screw it will be obvious that the parts (3 and C may be adjusted so as to have th ir position relative to the barB' and uprights B B, as well as to the other ad-v jacent parts, sufficiently changed to enable allthe mechanical devices to operate in perfect union for the accomplishment of the best-possible results in the practical use of the motor.

At the left-hand end of the frame is a skeleton upright D, which is parallel to the uprights 13 and G, and which is secured at its upper end to the under surface of the machine-table. The lower end of said skeleton upright D is provided with a bevel-tongue, which is adapted to dovetail between the beveled flanges c 0 formed on the upper side of the longitudinal bar 0 at the end thereof opposite the end 0. The lower dovetailed tongue is connected to the bar C by means of a suitableconnecting-screw. (SeeFig.3.) Furthermore, the motor-frame comprises a lower or bottom skeleton frame E, (shown in section in Figs.3 and8and in plan in Fig. 2,) said frame E having one part parallel beneath the longitudinal bar C' and another right-angled integral part parallel beneath one side of the transverse part (1*, as shown in the plan in Fig. 2. Said skeleton bottom frame E is securely connected to the lugs c c 011 the under side of the bar C and a lug on the under side of the bar C by suitable attaching-screws, and the main purpose of this skeleton part is to permit the arrangement therein and therewith of the devices by means of which the spring is wound. Thus it will be seen that the frame taken all together is a skeleton construction, consisting of the fewest possible parts, and therefore being as light as is consistent with suliicient strength to support the mechanical devices. The other parts of the motor-frame are the horizontal transverse bars B 0', and C The transverse horizontal bar B connects the uprights B B and is located a short distance below the upper ends of these uprights. The transverse bar 0 connects the uprights C O and is located a short distance below the upper ends of these uprights. The transverse bar 0 connects the uprights O C and is fixed at about mid way of their height. These several transverse pieces may be connected in any manner that may seem best. A convenient way of locating the cross-bar C in place is to form lugs on the inner sides of the uprights C C and allow the cross-bar O to rest at its ends thereon,said ends being likewise enlarged to permit attaching'scrcws which pass through the uprights C C to enter them and firmlysecure the cross-bar in place.

F denotes a drum of suitable width and diameter having a cover F, which is preferably a skeleton cover and which is secured to the upper edge of the drum, as shown. The under side of the drum is formed with a central boss or enlargement, which is seated upon the bottom bar 0. Said under part of the drum is preferably made in skeleton form, as shown in Fig. 2, consisting simply of the radial arms a a, which arms are preferably provided on their upper sides within the drum with ribs, as indicated in Fig. 3, upon which rests the spring G, the ribs serving to diminish the friction when the spring is being wound or is unwinding.

Passing centrally through the drum F and likewise through the bottom bar C of the motor-frame is a tube or shaft H, which may be either hollow or solid and which is formed integral with a friction-wheel H on the lower end of the part H, beneath the bar C as shown in Fig. 8, the said friction-wheel and its integral shaft or tube being shown in detail in Fig. 6. The upper end of the tube H has a bearing in a circular recess formed in the under side of the transverse bar C (See Fig. 3.)

Surrounding the tube H within the drum F is a sleeve or thimble G which is keyed to the said tube H, so as to rotate therewith. The key 9 (shown in Fig. 6) is used to effect this connection. Furthermore, it will be seen that the spring G is located within the drum F and is coiled around the sleeve G,one end of the spring being connected to the wall of the drum, as shown, while the other end is connected to the sleeve G by means of a screw or other attaching device g. This spring G drives the mechanism of my machine. It may be of greater or less size and power. Obviously the rotation of the friction-wheel H and its integral tube H in one direction will revolve the connected sleeve'G and thus cause the connected spring G to Wind up and become closely coiled,so that when it unwinds it will serve to actuate the gearing,

IIO

the drum F during the unwinding of the spring revolving upon the tube II, which serves as a journal therefor.

The drum F is provided with a frictiongear or friction-wheel I. This may be of equal or less diameter than the drum, in the example shown in the drawings the friction-wheel I being of less diameter than the drum and is located above the latter, being mounted upon the skeleton cover of the drum and securely connected thereto. This frictionavheel I maybe differentlyarranged with relation to the drum to which it is connected. Experience will dictate how it may be best affixed thereto, and I reserve the liberty of adopting the best form thereof which may be suggested in practice. This friction-wheel I is preferably provided with a grooved perimeter or periphery.

.The drum or barrel F connects with the driven machine through a novel system of gearing, which I will now proceed to describe. Parallel to the tube H is a vertical shaft J, having a bearing at its upper and lower ends in the cross-bar l3 and the bottom bar B, respectively. The upper and lower ends j of this shaft are preferably pointed, so that the friction thereof within the bearings may be diminished. The bearing in the bar B, is simply a seat formed therein, having an annular recess around theshaft J, adapted to rcceive the oil or other lubricant and keep the action thereof constant upon the hearing. The bearing of the upper end of the shaft is a screw-threaded plug 1), which screws into an internally screw-threaded opening in the cross-bar B This plug b may therefore be adjusted up or down,so as to regulate the position thereof and take up for wear. It is provided with the central vertical passage, at the upper end of which is formed a cup, said passage being adapted to convey the oil or other lubricant to the upper shaft-bearing while the cup receives the lubricant and delivers it to the passage. This is shown in Fig. 3. The shaft J at about midway thereof is preferably formed with an enlargement or collar J Beneath this is a screw-threaded section J. On this screw-threaded section is a friction-wheel I), being a thin horizontal wheel made of some suitable material. This wheel I) may be adjusted up or down upon the screw-threaded portion. Beneath it is a nut j so that after the wheel has been adjusted up closely againstthe collar J 2 the nut 7' may be screwed firmly into place against the under side of the wheel, and the wheel thus securely and rigidly connected to the shaft at the proper point. The periphery of this friction-wheel b is in close contact with the periphery of the friction-wheel I, belonging to the drum F, and it enters the groove in the periphery of the wheel I, thus increasing the tractive force. Likewise on the vertical shaft above collar J 2 is a friction-wheel K, preferably having a considerably larger diameter than the friction-pinion b, the hub of said friction-wheel K having a setscrew whereby it is firmly connected to the shaft J, and the periphery of said wheel K being grooved.

Parallel to the shaft .I and directly in line above the tube II is another short vertical shaft L, having bearings at its upper and lower ends in the transverse bar 0' and the transverse bar C respectively, said upper and lower ends of the shaft L being pointed atZ Z. The bearing for the lower end Zof the shaft L is simply a proper recess in the crossbar 0 permitting space enough to contain a lubricant around the shaft, which may act at all times upon this hearing, so as to keep the action free and easy. The bearing for the upper end of the shaft L is formed in a plug Z, similar to the plug b, said plug Z being screw-threaded and situated within a screwthreaded opening in the transverse bar 0'. On this shaft L is a friction-pinion d, and also a bevel friction-wheel M, having a hub M, provided with a set-screw e, whereby itisrigidly connected to the shaft L. The frictionwheel M has a flat rim and is beveled horitally, so that it serves as a beveled frictionwheel, being of a diameter substantially equal to the friction-wheel K.. The friction-pinion d engages with the grooved peripheral surface of the wheel K. The shaft L is screwthreaded for a certain portion of its length at and below where the friction-gear (Z is 10- lated at L, and a nut L travels on this screwthreaded part and binds the friction-pinion d closely between it and the hub M of the beveled friction-wheel.

In the right-hand skeleton part D of the motor-frame is journaled a horizontal shaft f, having suitable hearings in said frame. That portion of this shaft outside of the frame D is preferably screw-threaded, and on this screw-threaded portion is a bevel friction-pinion N, on one side of which is a nut 01 and on the other side a nut 77., the said bevel friction-pinion being adjustable within certain limits. This friction-pinion is in contact with the bevel friction-wheel M. (See Fig. Likewise 011 the shaft f within the skeleton frame D is a peripherally-grooved pulley it, around which passes a belt or band m, which runs over the wheel on on the sew ing-machine shaft, all as clearly shown in Fig. 1. Thus it will be seen that the belt m serves to carry power from the peripherallygrooved pulley It to the shaft of the driven machine whatsoever that machine may be.

Referring to Fig. 3, it will be seen that the bevel friction-pinion N is beneath the bevel.

friction-wheel M. This drives the pulley it in one direction, as shown by the arrow alongside of said pulley, and thus rotates the shaft of the driven machine in one certain direction, imparting thereby to the driven machine a corresponding actuation and work. The beveled friction-wheel M, however, is reversible, so that it may be applied to the pinion N either above or below, thus rotating the latter clutch device.

either inone direction or the other, as may be desired.

' In Fig. 12 the wheel M is shown as applied to the pinion N, below the latter. This reversalof parts is easilyaccomplished bysimply removing the plug-bearing Z and then reversing the shaft L, which carries with it the connected wheel M and pinion d, placing them in the position shown in Fig. 12,where the pinion cl engages the periphery of the grooved frictionwheel K, just as it does in Fig.3, and the beveled friction-wheel M has its beveled frictionsur face beneath the beveled pinion N, acting upon the latter just as it does in Fig. 3, only in a reverse direction, and causing a reverse motion'ofthe pinion N, and consequently a reverse rotation of the pulley 7a, which now revolves in the direction shown by the arrow in Fig. 12, and consequently imparts to thedriven machine a change in its direction of movement.

Below the frictional wheel H is a bevel gear or pinion 0, having on its upper side or face (see Fig.5) a flange or lug 0 and a short rounded stem, the stem and flange being integral with each other and with the gear, and

on its lower side'a short pointed shaft orprojection 0. The flange 0 and integral stem are adapted to enter a recess h, formed in the face of thefrict-ion-wheel H, while the stem referred toprojects a short distance into the tube H, as shown in Fig. 3. In this way the gear 0 is loosely connected to the frictionwheel, so that it will rotate therewith, but can be easily disconnected therefrom when desired. It will be noted that it supports the said wheel H and its tube, keeping the upper end of the latter within its bearing in the cross-bar (1 The down ward shaft or pointed projection 0 has a suitable bearing formed in the part oftheskeleton frame E directly beneath the gear 0. Thus the gear is free to turn, and in its turnings it rotates the friction-wheel-I-I.

By referring to Figs. 3 and at it will be seen that on opposite sides of the wheel H are dogs P P, seated looselyin sockets formed in the longitudinal bar 0 of the motor-frame, said dogs having curved faces which come in contact with the periphery of the wheel H, and saiddogs being provided each with a spring 19, thetendency of which is to press the dogs against the wheel.

As the wheel H revolves in one direction it will push the dogs out of its way, thereby compressing the springs 19 p; but these dogs P P quickly clutch the said wheel H and prevent any reverse movement thereof-t Thus the wheel H and connected tube H may be rotated forward a sufficient number of times to wind the spring G tightly and coil it closely together, and the dogs PP will-serve to hold the collar H, and consequently the spring, in the position in which the-latter may thus be placed. The diameter of the tube or shaft II relatively to the-fric-' tion-wheel Hmay vary. I am not, therefore,

Here, then, is a sort ofrestricted to the particular size of this part, as shown in the drawings, but reserve the liberty of making the collar of any size and diameter relatively to the tube or shaft with which it is formed integral.

In order to rotate the gear 0 and thus wind the spring'G, I provide certain winding devices consisting of the following parts: R denotes a horizontal shaft journaled in suitable hearings in the skeleton frame E, the inner end of said shaft B being preferably pointed and having its bearing, as shown in Fig. 8, closely adjacent to the bearing of the downwardlyprojecting pointed shaft 0, which belongs'to the gear 0, so that an oil-hole, as shown in Fig. 8, may communicate from one bearing to the other, and thus the lubricant which is fed in around the bearing forthe shaft 0' will leak through into the other bearing and oil the latter sufficiently to permit easy movement of the shaft R. Secured upon this shaft R is a beveled pinion R, which intermeshes with the pinionO, said pinionR' being vertically placed. Likewise on the shaft R are two collars r 1, provided with set-screws, so that they may be adjustable upon the shaft, one of said collars being screwed up tightly against the pinion R, while the other is screwed tight upagainst the outer bearing of the shaft Q denotes a winding-lever having at the outer end thereof a suitablyformed handle attached at right angles, as usual, and easy to be grasped forthe-purpose of vibrating the said lever. The end of this lever is formed with a circular opening (see Fig. 1) wherein is placed a friction-wheel Q, which has a central square opening of suitable size to fit neatly over the square end of the shaft R. within the recess which it occupies in the end of the lever Q (covering, as it does, the circular opening in said end) by means of the plate Q which is perforated with an opening less in diameter than the diameter of the disk Q, said plate Q being fastened to the face of the lever Q by screws or other means, it being shown in detail plan in Fig. 10. \Vithin the end of the lever adjacent tothe periphery of the disk Q is a dog Q having a curved end in contact with the periphery of the disk Q, said mechanism thus operating and acting as a clutch, for while the lever vibrates in one direction the dog Q will slip loosely over the periphery of the disk, the latter remaining stationary; but when The wheel or disk Q is held IIO the lever Q vibrates in the opposite directegral tube on which the drum revolves, and thereby effecting a partial winding of, thespring. A few vibrations of the Windinglever Q will therefore wind the spring upto its highest tension.

Itwill be observed that the winding-leverQ may vibrate in either direction, and that if it is placed upon the shaft R in the position shown in Fig. 1 the result of vibrating it in the direction shown by the arrow in this figure will be to wind up the spring, whereas if it be placed upon the shaft R in the position shown in Fig. 8 itmay be vibrated in the reverse direction with the etfect of winding the spring. Furthermore, it will be observed that it can be easilydetached from or at fached to the shaft R. After the spring has been wound, the handle being in the position shown in Fig. 1, it can easily be removed and the lever placed upon the shaft as it is shown in Fig. 8,whereby it is out of the way and the right-angled handle at the end thereof projects inwardly instead of outwardly, and the parts are more compactly arranged and less in the way of the operator in running the machine.

In order that the motor may be started at any moment with promptitude or may have its motion quickly and speedily arrested at any ti me, and, in fact, governed and controlled at all times, with little effort on the part of the operator, it becomes necessary to provide an eliicient brake device. I will therefore at this point explain'the' form of the brake herein employed, although other forms may of course be used with other forms of the motor. I preferably apply this brake to the pulley 7r, which, as is seen, carries the band or belt m, which communicates motive power to the driven machine.

Fig. 9 illustrates clearly a certain part of the brake mechanism, and Fig. 1 shows the balance thereof, while Fig. 2 indicates in bottom plan the arrangement of certain of the parts. S designates a horizontal lever, which is fulcrumed below the machine-table at Said lever S carries the brake-shoe S, which enters the grooved periphery of the pulley 7c. The shoe end of the brake-lever is provided, furthermore, with a projection s, which carries a springs, which bears against the frame and presses downward upon the brakeshoe, holding the latter tightly against the grooved periphery of wheel 7t. Near the other end of the brake-lever S and at right angles thereto is a right-angled or bell-crank lever T, fulcrumed at its vertex on the pin 25, one arm of which lever bears upon the end of the lever S, preferably entering a slot or notch 5 cut in said lover near the end thereof. To the end of the other arm of lever T is connected a rod or cord 11, (shown clearly in Fig. 1,) which preferably runs to the other side of the motor and is attached to one end of the lever V, f ulcrum ed at t: on some suitable part of the motor or machine frame. Vertically below this lever V is another lever U, which carries a foot or knee pad it, said lever Ubeing fulcrumed at 1/ and having its upper end pressing loosely against the lower end of the lever V below the fulcral point of the latter. It will be ob-' vious that by pressing upon the pad or plate a and pushing it in the direction shown by the arrow in Fig. l the result will be to shift lever U, which will interact with the lever V shifting it, as shown by the arrow, and moving its upper end in the direction shown by the arrow, and thus pulling the cord or red t sufliciently to shift the bell-crank lever T, and thus depress the outer end of the lever S, whereby the brakeshoe S will be removed from the pulley 7,: and the spring 5- temporarily contracted. "hen the pressure upon the lever U is released, the tension of the spring .9 will serve to restore the brake-shoe to its position in contact with the periphery of the wheel 7;. g

The operation of my improved spring-mo tor will be evident from the foregoing description of the construction and arrangement of the several parts. A few vibrations of the winding-lever will be sufficient to quickly and surely coil the spring to its highest tension. This winding operation may take place at any time whether the motor is running or at rest. hen it is desired to start the machine, the operator will simply press upon the brake mechanism, so as to remove the brake-shoe from the pulley 711 and allow the coiled spring to actuate the train of multiplying frictiongears, so as to drive the shaft f and pulley 7t thereon, and thus actuate the driven machine. If it be desired to drive the machine in a reverse direction, all that the operator needs to do is to reverse the position of the bevel friction-wheel M.

The several adjustments in the different parts of the frame and for the different wheels of the motor mechanism enable the operator to keep his machine in perfect condition at all times, so that it will do the best possible work and cannot get out of order. Furthermore, the provision of a train of frictiou-gean ing constitutes one great excellence and merit in this invention. Not only is the structure cheap to build, but it. operates with very great efficiency, a higher speed is attained, there is no noise in the operation of the parts, and the engagement of the friction-gears forms a very easy and light-running movement. Certain of these friction-wheels may be made of rubber, if desired, and this material will be found very valuable when it can be used for the purpose of making the wheels of this machine, because they will operate easily, freely, and efficiently.

Many cl'langes may he made in the precise construction and relative arrangement of the several parts of my improved motor without departing from the invention, and I reserve the liberty of varying the same as experience may suggest.

Having thus described my invention, what I claim as new, and desire to secure by letters Patent, is-
