CHANGE-GEARING EOE BRAIDING-MACHINES.

Specification of Letters Patent.

Patented Dec. 10, 1907".

Application filed Decemlier 4.1905. Serial No. 290.108.

Q Wyo1nissing, county of Berks, and'State of Pennsylvania, have invented certain new and useful Improvements in Change-Gearing I for Braiding-Machines, of whichmhe following is a specification.

My invention relates to certain improvements in braiding machines whereby the changes-which are required to be made in the gearing in order to make desired changes in theproduct, may be efiected with greater ease and in shorter time than heretofore, and the construction of the machine at the same time be simplified.

The changes commonly desired merely re'- quire that the number oi carriers employed shall be varied by means of different term]- nali gears for reversing the course of the carriers ;-for instance a five-horn terminal gear, that is one having a carrier driving-head provided with five carrier-engaging notches, as commonly employed in making plain braid, a six-hornfor diamond braid, and a three-horn for open-work; and the speed of rotation of these different terminal gears must be correspondingly varied by providing a proper proportion'ol' treth in the meshing terminal and adjacent gears.

The main object of my invention is to enable these variations in the machine to be easily and simply effected, and it consists in providing for changing the terminal gears only as desired without requiring any changing of the adjacent meshing gear, or of the location of the terminal stud to vary the distances between the gear centers.

.The invention is fully described in connection with the accompanying drawings and the novel features are clearly pointed out in the claims.

Figure 1 is a partial sectional elevation of a braiding machine embodying all the features of my invention; a terminal three-horn gear and the adjacent four-horn gear only being shown in operative position. Fig. 2 is a similar view to Fig. 1 showing the terminal-gear stud removed and a five-horn (or six-horn) gear put in place of the three-horn and ready to be secured by replacing the stud in its original position. Figs. 3, 4, and 5 are plan views respectively of the three-horn, tivchorn and six-horn gears which are inter: changeably mounted upon the terminal stud.

A and B represent respectively the usual bottom and top plates of a braiding machine, between which the series of horn-gears for operating the bobbin-carriers are mounted upon a corresponding" series of vertical studs or bolts hired to the bottom plate A. Only the terminal-gear stud 2, upon which the difierent terminal-gears are interchangeably mounted, and the adjacent stud 3 upon which the end one of the usual four-horn gears is mounted, are illustrated, these only being necessary to the showing of my invention.

The four-horn gear which is mounted upon the stud 3 is shown in Fig. 1 as a compound gear, diil'ering from the other ordinary fourhorn gears only in being provided with an additional toothed Wheel 5, located in a plane above the drive-gear 6, which latter is the same as on all the four-horn gears; this additional toothed wheel being added in this case only to provide for the change to the threehorn gear shown on the terminal stud 2 in Fig. 1', and being an unused idler when either v80 the five-horn gear (Fig. 4) or six-horn gear (Fig. 5) are mounted on said terminal stud.

It being necessary that the ditl'erent termiears which areinterchangeably mounted nal g1 v on t .eterminal stud 2, be rotatedat diflerent- 1 speeds corresponding to the different number of-carrier-engaging notches or horns with which they areprovided, the change from one terminal gear to another has heretofore involved the changing of the location of the terminal stud 2 relative to the adjacent, stud 3, and the changing of the horn-gears upon both of said studs, so as to secure the required speed of rotation of the particular terminal-gear employed. In my improved construction I provide for maintaining the terminal stud 2 in a fixed location, and at the same time for avoiding any change of the horn-gear on the adjacent stud 3; the chang ing of the terminal gears only being required, and this-chan e being effected in a simple, expeditious an satisfactory manner.

To aocomphsh this '1 permanently space the terini nal stud 2 from the adjacent stud 3 a distance somewhat greater than is ordinarily required for the proper s eeding of the five horn ear and somewhat ess than is required for t e six-horn gear. For instance, the four-horn driveear 6 havingtwenty f0ur teeth (three inc es itch circle), the fivehorn gear 7 will require thirty teeth and the six-horn gear 8 thirty-six teeth, requiring pitch diameters of three and three fourth inches and four and one half inches respectively; and instead of providing for changing the location of the stud,2 to one or other of the different spacings from stud 3 required by these different pitch circles, I adopt a fixed spacing based on a compromise pitchcircle of four and one quarter inches for both the five-horn and'six-horn terminal gears, or three and five eighths inches s acing between studs 2 and 3; and instead'o providing the different terminal gears with normally shaped teeth (thirty-four to each gear) I make them both bastard-gears of thirty teeth and thirty-six teeth respectively, as indicated in 'same. in order that all Figs. 4 and 5, in which it will be seen that the teeth of the five-horn gear are abnormally pointed and wide of. the six-horn gearare abnormally blunt and narrow at the base, both forms of teeth however being adapted to mesh properly with the normally toothed four-horn driveear 6. Thus either the five-horn or sixorn terminal gear may be employed upon the fixedly spaced terminal-stud 2, and each will be driven by the adjacent four-horn gear at the roper speed. When only three horns or note es are wanted in the terminal gear, the additional toothed-wheel 5 on the adjacent four-horn gear (see Fig. 1) comes into service, a compound three-horn terminal gear being preferably employed as shown, in which the ower gear 9 is turned idly by the adjacent ve-gear 6 to transmit movement to an adjacent gear (not shown) on the opposite side of the terminal stud, while the threehorn terminal gear is driven by said additional toothed wheel 5 of the four-horn gear 6. The required relative rotation of said gear 6 and of the three-horn terminal is obviously secured by making the relative number of teeth in the additional toothed-wheel 5 and in the u per gear 10 of the three-horn terminal, as our to three; and where the idler 9 is not em loyed, these teeth ma be made of normal s ape. But when such idler is employed, as is preferable, it is necessary that the difference between the two pitchcircles of eachcompound gear shall be the may properly mesh and I secure this result by making both the upper gears (5 and 10) bastardears, the additional toothed wheel 5, in t e specific construction described and illustrated, havat the base, while those ing a pitch-circle offour and fourteen one hundredths inches with thirty-two teeth, and

nal a pitch circle of three and eleven one hundredths inches with twenty-four teeth, and each varying one and fourteen one hundredths inches from the pitch circle of the corresponding lower gear.

terminal gears as desired I employ a terminalstud 2 having a body portion 11 of uniform diameter throughout, a reduced lower end 12 secured in a fixed perforation in the bottom plate A by a removable nut 13, and a reduced upper end 14 "of the top plate is secured; an arcmovable collar 15 seated upon the bottom plate and upon which the rotary horn-gears arellmounted. In order to substitute an- ,other of the terminal gears for one in service, the nut 13*is merely removed, the stud 2 (with quoit l4 and needle post 16, if emplqyed, attached) raised through the termina laterally and the different one substituted, and the stud returned to its original position and secured as. before.

The considerable saving in time and labor involved in making a change, as Well as the simplicity and economy of my improved construction will be readily understood.

The preferred construction specifically described and shown may readily be modified.

A braiding machine comprising a series of gear studs with meshing four-horn gears thereon an end one of which is a com ound gear, and a terminal gear stud remove 11 cured at a distance from said end fourorn stud which is intermediate between the normal distance for a five-horn and the normal distance for a six-horn gear, whereby different terminal horn-gears as described may be interchangeablymounted upon said terminal stud in required relation to said end fourhorn ear substantially as set forth.
