To all whom it may concern:

Be it known that I, FREDERICK South Bethlehem, in the county of Islo'rthampton and State of Pennsylvania, have invented certain new and useful Improve ments in Reed-Motions, whereof the follow-t ing is a specification, reference being had to the accompanying drawings. r

My invention ing more easy relates to means for render the passage of the warp threads between the reeds of a loom, and also for. simultaneously distributing the wear occasioned'by the contact of the threads and the shuttle with thereeds. It is. applicable to looms for weaving various fabrics and for weaving either narrow or wide webs.

To effect these purposes my invention consists ofa reed frame to which is imparted a vertical reciprocatory motion in addition to its normal horizontalreciprocatory motion. It willbe understood that I do not here use the term vertical and horizontal ina mathematical sense, for 'the'vertical motion is not strictly such, owing to the varying inclination of the lay, and the horizontal motion is not strictly such, becauseowing to the pivoting of the lay, the reeds move in an arc of a circle; butwith this explanation, Iwill use the phrases v ertic'al reciproca tion, and horizontal reciprocationfl to indicate these two differing motions of the reed frame always at rlght angles to ea ch other.

play as it falls back, the movementbeing continuous throughout the stroke. In this way the reeds aregiven a'sliding motion asthey beat backand forth along the warps, whereby the passage between two adjacent" reeds of any lump or enlargement of the threads, is rendered more easy, and the threads smoothed out so as to allow passage without breakage; and apart from abnormal the threads it is to be noted enlargement of that a Warp passes more easily over a reed or dent with which. it is in contact if the rela- Specification of Letters Patent.

OTT, of

According to my invention, for the, pure tive motions of the two have a diagonal resultant. fFor the purpose of accom lishing the other end of my invention, I ma e provision wherebythere is a constant variation in the limits of the vertical position of the reed frame from heat to beat, having reference both to the position in which the lay falls different portion of each reed in contact with the warps on either side of it at each beat of the reed, thus effectually distributing the wear and reventing the formation of those well de ned variations" in the'thickness' of the reed, due to wear, such as ordinarily o'ccurfat that point of the reed which marks the limit of its contact with the warps. In thislway I lengthen the life of the reeds. Likewise the same varia tion in the vertical position of thereeds as they fall back causes a similar variation; in the line along which the shuttle rubs against the reeds as it traverses the raceway and in this way I distribute this wear and prevent the formatlon of a corresponding groove 7 along the face of the, reeds. f

' back, and the position in which it, beats up. a This brings a slightly In the accompanying drawings, FigureI,"

is a sectional view showing the a plication' of my invention to a loom. Fig. I is a partial front elevation of the lay and reed frame.

"In said drawings,.the, lay 1 is mounted upon the swords 2, which are pivoted at 3 to each side frame 4 of the loom. The reed frame 5 holding the reeds 6 is secured on each end to a strap 7 having a boss 11 on its lower end through which'the shaft 8 passes. This shaft thus forms a sup ort upon which the reed frame is pivota ly mounted. Said shaft8'is mounted in the up er end of links 1( upon each side of the mac iineand is kept in p ace by'collars 17. A shaft 12 suitably journaled in adjustable bearings '13, on the side frames 4, is rovided with two eccen trics 14, about eac of which one of the links 10 is mounted to move freely. The bearings 13 are slidably mounted onthe side frames 4 and may be adjusted to vary'the position of the reed frame. The upper ends 9 of links 10 are free to'move in slots 15, in the swords 2. The swords 2 are also provided with slots 16 into which the ends of the shaft 8 roject. Thus when the lay-1, is moved orward and backward in the act-of beating up the filling thread,

the reed frame 5, is a new region of given a vertical recipro'catory motion at right angles 'to the'beat of'the lay, and coincident therewith, that is to say, as the lay moves forward the reed frame is continuously lowered, and as the lay moves backward the reed frame is continuously raised. 1

This relative motion of the reed frame and lay takes place at each beat of said lay. This vertical motion of the reeds with respect to the warp threads tends to smooth out any lumps or inequalities in said threads thus insuring their free action to form the shed, and generally renders the passage of the warps between the reeds more easy. Owing to this fact a cheaper grade of ma terial may be employed in the warp.

Extending downwardly from the front of each strap 7 is a rod 22, having its lower end adapted to bear against a buffer 23, mounted in a convenient position upon the frame of the machine, when the lay is in its forward position as shown in Fig. I. Secured to the upper front face of each of said rods 22 is a metal strap 18, to which the lower end of a spring 20 is attached. The upper end of each spring 20 is attached to a sword 2. These springs are comparatively light and tend to keep the reed frame in its proper position with relation to the swords, yet allowing it to move up and down with only a slight amount of friction. I

Power is applied to the crank shaft 30 having fast thereon the gear wheel 32. Said gear wheel 32 meshes with a gear wheel 33 secured to the shaft 34 j ournaled in the lower part of the side frames 4. The crank shaft 30 is provided with two cranks 36, one at each side of the machine, and said cranks are connected by means of links 38 with the shaft 8, by which the oscillatory motion is imparted to the lay 1.

Mounted upon the shaft 34 is a sprocket Wheel 35 connected by a chain 39 with a sprocket wheel 40 on shaft 12.

The operation of the device is as follows: The lay -1 is oscillated in a well known manner through the connection of its swords 2 with the crank shaft 30 by means of the rod 8 and links 38. The rotation of the crank shaft 30 and gear 32 is transmitted by gear 33 to shaft 34 and sprocket 35. Said sprocket 35 by means of chain 39 drives sprocket 40, and shaft 12 connected therewith. It will be noted that the motion imparted to the eccentric 14 on shaft 12 is slow owing to the manner in which the gearing is employed to reduce the speed from the shaft 30 to shaft 12. Accordingly as the eccentric 14 rotates, a slow but constant variation is occasioned in the limits of the vertical motion of the reed frame 5, as imparted to it by the link 10, connecting said frame with the eccentric, thus constantly presenting a the reeds 6 for contact with the threads and to the extent of said eccentricity. Furthermore, by varying the position of shaft 12 by adjusting its bearings the extent of movement of said reed frame may be further varied.

It will also be noted that when the lay is i moving forward to beat the filling into its final position, the reed frame will be tilted backwardly if it were not for the engagement of the rods 22, with the buffers 23 which tend to keep the reed frame in an upright position, and are aided by the springs 20.

It will be understood that I do not limit myself to the specific means herein shown, as it will be evident that other means may readily be employed for accomplishing the same purposes. Furthermore it will readily be seen that I ma employ means for reciprocating the reed frame vertically at each beat without the employment of the additional means for slowly Varying the limits of its vertical position. I may also employ means for slowly varying the vertical position. of the reeds for the purpose of distributing the wear thereon without employing means for reciprocating said reeds at each beat of the lay.
