Specification forming part of Letters Patent No. 45,208.

dated Novenib cr'22, 1864.

To aZZ whom it may concern:

Be it known that I, Pnnvnns L. SLAYTON, of

the city, county, and State of New York, have invented certain new and useful Improvements in GircularLooms for i/Veavin g Hats and other Articles 5 and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art'to make and use the same, reference being bad to the accompanying drawings, forming part of this specification.

This inventiongs designed more especially for apphcation in connection with the improvements in circular loomswhich constitute the subject-matter of Letters Patent No. 41,-

466, butmight be applied to other circular looms.

Its object is, first, to provide for the weavg of the brim of the hat of an elliptical or elongated form approximating to that of the human head, or to weave any other article in elliptical form; and to this end it consists in giving the pressing-up devices which areused to press the weft into its place in weaving the top of the crown and brim a movement toward and from the center of the loom twicein every revolution of the revolving parts of the loom while the weaving of the brim is being performed, each movement toward and each movement from the center occupying the same .time as one-quarter revolution.

The invention consists, secondly,in making the connection between the upper clamping or pressure plate, which is used to press upon the inside of the top of the crown of the hat while the weaving oi" the side is being proceeded with, and the central sleeve, to which the said plate is attached by means of a universal joint or its equivalent, so that the said plate will operate with a yielding pressure opposite that point in its circumference where the weaving is being performed, by which means a better operation is produced and the liability to break the warp'strands is obviated.

Figures 1 and 2 in the accompanying drawings are top views of a sufficient portion of the loom to illustrate the first part of my invention. Fig. 3 is a side view of some of the parts. Fig. 4 is a central vertical section of the upper clamping or pressing plate and of part of the central sleeve to which it is attached, showin g the ballaudsocket connection.

Similar letters and numbers of reference indicate corresponding parts in the several ii ures.

The parts not represented in the drawings or herein particularly described may be supposed to be the same as described in Letters Patent No. 41AM.

J is theforked ing the strai roller M;

In Fig.1 the parts are represented in the proper positions for weaving the top crown of the hat in circular form. The yoke J is cured firmly to the shuttlecarrier J by means of two screws, 50, which pass through slots in the yoke and screwed into tapped holes in the carrier, and is prevented from moving thereon by means of a projection, 51, on the carrier enteringa corresponding hole in the yoke, and a projection, 52, on the yoke entering a corresponding hole in the carrier. The small circle (32 in this figure represents the filling line, the weaving not yet having proceeded far from the center of the top of the crown.

In Fig. 2 the yoke is represented in condition for weaving the brim of "the hat in elliptical form. The yoke is placed farther back on the shuttle-carrier and the screws 50 50 screwed into two holes farther back on the shuttle-carrier, and the projections 51 and 52 are inserted into slots 51* and in the yoke and shuttle-carrier, the length of the said slots and of the screw-holes in the yoke being snfiicient to permit the necessary movement of the yoke back and forth a distance equal to the diii'erence between the greatest and least diameter of the ellipses in which the brim is woven. The red circle in this figure represents the outline of the top of the crown, and the ellipse shown in blue color shows the elliptical form of the commencement-of the brim, the lower edge of the side of the crown being held in this shapeby'making the former described in Letters Patent No. 411,466 elliptical instead of circular, as therein described.

' The yoke J has attached to one side of it a long pinion, 53, the journals of which are fitted to bearings, 64. 65, secured to the yoke, 1 so that the said pinion can have no moveyoke secured thereto and carryght presser- L and the pressing- J is What is called the shuttle-carrier, and

. ing movement of the yoke.

"of the said pinion there is secured a cam,

ment end wise independently of the yoke. The axis of this'pinion is parallel with the slid- To the inner end 56, which bears against'a'shoulder, 57,'pr0- 'vided on the carrier'J or. against an anti-friction roller attachedthereto. The pinion gears with a bevel-gear, 58, on fa shaft, 59, which works in bearings 54 55 in or ona frame, 60, which is securedt'o the middle one of the rotating ringsot the-100111.;- ring is tho'wnin thedrawings, marked n. The

Aportion of this said shaft 59 .is i'urnished outside of the said frarne'and outside of the ring n with a ratchetwheel, 61, which is turned-one tooth at a the machine.- The number of these stationary teeth i s equalto twice the number of teeth in the ratchet-wheel to produce two revjolutions of the said wheel and its shaft and pinion during each revolution "of the ring n i and the shuttle and. devices for pressing np the-,filling. Thecam- 56,'acting .agai-nst the shoulder 57, causes the yoke with its attached presser L and pressing roller M and its attached end of the shuttle to-approach the cen-- ter of the loom once duringweach of its ;revo-- lutions and twice'during each revolution of the shuttle and pressing devices. The arerangement of the cam must be such as to proa ytluce this movement toward the center as the p'ressin g devices revolve fromthe larger toward the smaller diameter of the ellipse." The removed out of gear it is so fitted to its shaft ,1

time by its teeth coming in contactwith anumber of stationary teeth, 63, (see Fig. 3,) secured .to the upper stationary ring, B*, of

as to be capableof being slid back thereon, as shown in Fig. 1. V

The above-described movements of the weftpressing. devices toward and from the'center of the loom are entirely independent of the slow outwardmovement .which takes place as the brim increases in size inthe weaving process, and which is produced by the screw J B, Fig. 4, is the upper clamping or pressing plate f0! pressin .on theinsideof theztop of-the'crown of the at while the sides'are being woven, and R is the central sleeve to which it is attached. m 'n is the ball-andsocket joint by which the connection between the said plate and tube is formed, the ball part m being secured firmlyinto the sleeve and the socket part n to the back of the plate.

It will be understood that this joint' allowsthe plate to cant to some extent in any direc--- tion, and makes its pressure'at any given point yielding. The plate thus applied may be used without the lower clampin g plate de-,

- scribed in my Letters Patent-hereinbefore re ferred to. 1 do not confine myself to the use of any par: ticular means of producing the within described movementsof the weft-pressin g devices toward and'from the center of the lo'omdurin g v each revolution but What I claim as my invention, and desire"v to secure by Letters Patent, is-

1 Giving th'e vweftpressing 'devicesiofa circular; or rotary loom a movement toward and from the center of the 100m during each of the.revolutions of the loom',substantially as anti for the purpose herein specified. 2. The-attachment of the plate 1t to the sleeve or its equivalent by means of a ball-andsocket'or other flexible joint of similar character, substantially as and for the purpose herein specified.
