MACHINE FOR FEEDING WELTS.

SPECIFICATION forming part of Letters Patent No. 749,719, dated January 19, 1904.

Application filed March 30, 1903. Serial No. 150,086. (No model.)

To all whom, it may concern.-

Be it known that I, GEORGE D. OLAPP, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Machines for Feeding Welts, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to feeding devices adapted for automatically delivering U-shaped welts one at a time to any suitable machine adapted to skive, groove, bevel, or color or otherwise operate upon them or to any suitable receptacle adapted to receive them, although said feeding device may be also employed for other purposes.

In accordance with this invention two inclined runways are employed, one in continuation of the other, but disposed at different elevations*as,for instance, the main runway is at a lower elevation than the auxiliaryrunway. Means are provided for lifting the welts from the main runway to a suitable elevation, whereby they freely pass by gravity onto the auxiliary runway, and means are also provided for removing the welts one at atime from the auxiliary runway and for delivering them to a suitable guideway along which they are free to pass. turn the welts end for end, and means are provided adapted to be brought into operation whenever desired for accomplishing this result. Means are also provided for directing the welts intothe guideway if for any reason they should be thrown too far outward by the means employed for delivering them thereto. An indicating device is provided for informing the operator whenever two or more welts become superimposed in the guideway.

Figure 1 shows in plan view a machine for feeding welts embodying this invention. Fig. 2 is a side elevation of the machine shown in Fig. 1. Fig. 3 is a vertical section of themachine shown in Fig. 1, taken on the dotted line 3 3. Fig. 4 is a side elevation of the machine, the means provided for turning the welts over endwise being omitted. Fig. 5 is a detail of a part of the means employed for turning the welts end for end.

The base a of the machine has erected upon In some instances it is desirable to it an upright frame a, which comprises, essensentially, two flat side portions with a narrow space between them in which the operating parts are placed, said frame, being narrow enough to enable the U-shaped welts to easily astride it and to be supported upon the upper edge thereof. The upper edge of the frame on which the welts rest is formed to present a downwardly-inclined portion (11 which constitutes a part of the main runway, and a downwardly-inclined portion a, which constitutes the auxiliary runway, and a curved portion a, which constitutes an intermediate runway between the auxiliary runway and the guid eway.

An upright post I) on the base supports at its upper end the main part of the runway. The main part of the main runway comprises a downwardly-inclined portion 5, leading from the post to the runway (1 and a detachable downwardly-inclined portion or bar 5 the lower end of which is formed with a tenon, (see dotted lines, Fig. 2,) adapted to enter a socket provided at the upper end of the post. The welts are placed on said detachable portion or bar 6 and when said bar is properly disposed they will slide along the bar by gravity until they strike against the upper end of the auxiliary runway, as represented in Figs. 1 and 2. The auxiliary runway occupies a position at an elevation above the main runway, although in continuation thereof. The main, runway is made quite long, adapting it to receive a large number of welts, and when filled with welts the pressure upon the endmost or lowermost welt is considerable. In fact, so great is the pressure upon it that it is quite difficult to remove said endmost welt without disturbing the welts above it and a strong and durable device is required; but by employing an auxiliary runway and delivering the welts from the main runway thereto one, or at least but a few welts, will be carried by said auxiliary runway, and as a result the endmost welt can be easily picked off and delivered to the guideway. The auxiliary runway is adapted to receive several welts, so that in case more than one welt should be accidentally removed from the main runway the welts thus removed will be supf, bearing a driving-wheel f ported by the auxiliary runway, from which they will be removed one at a time.

The device employed for removing the endmost welt from the main runway is adapted tomerely lift the welt to asuitable elevation, whereby it can pass onto the auxiliary runway, which latter is located at an elevation above the main runway, and said Welt-lifting device consists of a finger f, passing up through a hole in the frame at the junction of the main runway and auxiliary runway. This welt-lifting finger is movable up and down by a lever f, pivoted at f, to one end of which said finger is loosely connected, the opposite end of said lever being mounted upon an eccentric disk f secured to a shaft f, bearing a toothed wheel f The toothed wheel f is engaged by a toothed wheel f, secured to a shaft f and said toothed wheel f is engaged by a pinion f secured to a shaft By means of the train of gearing the lever f is operated to reciprocate the welt-lifting finger f. As the finger is reciprocated the welts are lifted one at a time to an elevation, whereby they are free to pass onto the auxiliary runway, and if by accident more than one welt should be so lifted then all the welts thus lifted will pass onto the auxiliary runway; but in the ordinary running of the machine but one welt will be lifted. As there will be but one or at the most buta few welts on-the auxiliary runwvay at a time, it is easy to remove the endmost welt by a suitable pick-off device .and to deliver it to the guideway. The pick-off device herein shown for removing the endmost welt consists of a finger g, secured to one side or face of a toothed wheel 9, mounted on a shaft g said toothed wheel being engaged and driven by the toothed wheel f The finger g is moved a complete cycle by the toothed gear g during each revolution thereof and takes the endmost welt from the auxiliary runway and delivers it to the guideway, the welt during its passage being supported on the intermediate runway. The intermediate runway is curved approximately concentric to the axis of the toothed gear and is slotted for the passage of the finger.

The guideway consists of a trough composed of two similarly-constructed portions h h,

each having a curved bottom and an upright lip at its outer edge. The trough is made in two parts in order that the two parts thereof may be adjusted to provide for welts of different widths. As herein shown, each part has formed or provided on it an ear h having a slot 7& for a screw having a thumb-nut thereon. The base-plate, to which the parts it h are ad ustably secured, has a recess or groove adapted to receive the ears k to there:

by more steadily hold the parts, and said plate has slots if, which receive screws having thumb-nuts thereon to provide for adjustment in and out.

To the upturned lip on the outer edge of each plate h h a shield j is secured, which is obliquely disposed and is employed to direct the ends of the welts inwardly into engagement with the guideway in case they should have a tendency to swing out too far, but ordinarily this shield will not be used, although provided.

In some instances it is necessary to turn the welts over end for end as they pass into the 2 project one at each side of the upright frame a into the path of movement of the -lower ends of" the legs of the welts. As the welts pass along the lower ends of the legs thereof strike the upturned lips 2' and by them are more or less tipped out of perpendicular position, and then as they continue along the intermediate runway the lower ends of the legs pass along the oblique plates i, and by said plates the welts are further tippedout of perpendicular position until the-tops of the welts fall down into the guideway in advance of the legs.

At the exit of the guideway an indicating device is provided for indicating whenever two superimposed welts pass along the guideway, and, as herein shown, this indicating device consists of a gate it, the lower edge of which is elevated above the lower edge of the guideway sufficiently to permit a single welt to pass freely; but in case two superimposed welts attempt to pass from the guideway said gate will be swung outward. The gate k bears an electric contact is, which when the gate is swung outward strikes an electric contact 70 to thereby close an electric circuit 76 containing a suitable battery and bell or'other indicator.

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