SPECIFICATION'forming part of Letters Patent No. 333,947, dated January 5, 1886.

Application filed April 22, I855. Serial No. 163,010.

To all whom it may concern.-

Be it known that I, WILLIAM IIOUGHTA- LING, a citizen of the United States, and a resident of Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Sewing- Machines, of which the following is a specification.

My invention relates to sewing-machines, and has special reference to the driving mechanism.

The object of my invention is to provide for sewing-machines a self-belting drivingwheel.

My invention consists in providing a guide or series of guides for the belt, said guides at tached to the machine adjacent to the drivingwheel, which, in connection with a guide or take-up on thedriving-wheel, will secure the desired result.

To more clearly understand my invention, reference is had to the drawings, and to the figures and letters of reference marked thereon, forming part of this specification.

FigureI represents an end elevation of the driving-wheel, a section of leg through dotted line or of Fig. II, to which said wheel is attached, and also a section of table and machine with balance-wheel pulley connected thereto. Fig. II represents a front elevation of the driving-wheel, leg, and table, and asection of machine through dotted line :0 of Fig. I. Fig. III represents a front elevation, in section, of leg and driving-wheel through the dotted line 00 w of Fig. II. Fig. IV represents a sectional view of the outer rim of the driving-wheel through dotted line a? of Fig. II.

Its construction and operation are as follows:

A represents the driving-wheel; B, the leg; 0, the balancewheel pulley; D, machine; E, table; a, guide or take-up; b 0 cl, guides; e, belt; Z, crank-pin to connect with pitman.

It is necessary, frequently, to tip back the machine to oil or adjust the parts on the under side of the bed. To do this, the belt is removed from the driving-wheel, in order to obtain sufficient slack in the same for that purpose.

To replace the belt on the driving-wheel is (No model.)

a matter of considerable annoyance and trouble to the operator, and especially so to a novice. I propose with the aid of my device, while the driving-wheel is in motion, to accomplish this automatically, without further assistance from the operator. The upper guide, d, through which the belt 0 passes, is represented as forming an integral part of the leg B. It may, however, be adjustably secured thereto or to the under side of the table E. The guide 0, for conveniencein manufacturing,isadj ustably secured to the leg by means of screw f and elongated slot 9, and this guide, together-with the upper guide, (1, serves to keep the belt 6 always in the groove of that part of the wheel, as indicated by m, between said guides. The lower guide, I), on the center piece, F, serves to support the slack of the belt when the same is removed from the driving-wheel, as seen at Fig. 3, and operates to keep said belt within reach of the take-up a of wheel A. (A better view of guide I) and its relation to wheel A and take-up a is seen at Fig. I.) The take-up a is a plate forming a projection on the rim of wheel A, and maybe cast thereon, or attached thereto by the screws h h, as represented. IVhen the belt is thrown off from Wheel A, it will be entirely removed therefrom, except, as before stated, on that portion, m, between guides c and d, and will be in the position as represented in Fig. III. The guide 0, as will be observed, (see Fig. I,) is curved slightly at the end 1'. Said end is brought in close proximity to the wheel A, and serves to prevent the belt being disengaged therefrom. In replacing the belt on the wheel A all that is necessary is to turn the wheel, by means of the treadle or by hand, in the direction as indicated by the arrow, when the take-upa will engage with the slackened belt and gradually crowd it toward the groove of the wheel, replacing it therein.

In Fig. II will be seen a clear illustration of the operation of the take-up a, it having, as it were, picked up the belt, and is in the act of carrying it onto the wheel, as above described.

In constructing my device I do not wish to be confined to the use of all the guides, as

shown, for instance, the guide 0 being in its relation to the belt the most important of all the guides, by making the groove of wheel A deep enough, the guide d could be dispensed with. Then the deep groovein connection with guide 0 would operate to keep the belt in con tact with that part of the wheel, as indicated by m,- butinshallow-grooved wheels the upper guide, (Z, or its equivalent, would be indispensable. The exact shape or position of the guides is immaterial, solong as the conditions, as above described, are complied with-11 6., 50 arranged in relation to the belt that the said take'up will place the belt on the driving-wheel. As the take-up alone will not do this, it is of vital importance that it should have the co-operation of one or more of the guides, otherwise the operators hands will have to guide the belt; but with such co-operation the operation of the take-up is automatic and infallible.

In the arrangement as shown the position of the operator is supposed to be on the side of the machine indicated by G. As some machines run in the opposite direction, all that is necessary in such a case will be to change the position of guides c and d to the opposite side of the wheel from where they are now situated.

Having thus described my invention, whatI claim as new, and desire to secure by Letters Patent, is

1. In a belting device, as a means for replacing the belt on the driving-wheel, the combination, with a lug to operate as a take-up or belt-replacer, said lug secured within one edge of the driving-wheel, and projecting beyond the periphery of. the same, and having a radial and laterally-outward inclination, of a guide or series of guides secured to the adjacent parts of the machine, so that by the action of said guide or guides and take-up, in cooperation with the driving-wheel, moving in the right direction, the belt will be automatically placed in the groove of said wheel, sub stantially as set forth.

2. The combination, with the take-up a, secured within one edge of the driving-wheel A, and projecting beyond the periphery of the same, and having a radial and laterally-outward inclination, of the adjustable guide a, said guide operating to keep the belt in contact with the groove of the driving-wheel, substantially as described.

3. The combination, with the take-up a, secured within one edge of the driving-wheel A, and projecting beyond the periphery of the same, and having a radial and laterally-outward inclination, ofthe adjustable guides 0 and d, substantially as shown and described.

4. The combination, with the driving-wheel v A, having the belt take-up a situated thereon, of the guides 0, d, and b, all substantially as described, and for the purpose set forth.

Signed at Bridgeport, in the county of Fairfield and State of Connecticut, this 6th day of April, A. D. 1885.
