OTTO W. SCHAUM, OF PHILADELPHIA, PENNSYLVANIA.

LOOM.

SPECIFICATION forming part of Letters Patent No. 497,824, dated May 23, 1893.

Application filed October 17, 1892. Serial No. 449,131. (No model.)

To all whom, t may concern:

Be it known that l, OTTO W. SCHAUM, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Looms, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to the lathes or battens of looms, more particularly those of narrow-ware looms, and to the devices which are concerned in actuating the same.

One object of my invention is to enable the beam of the lathe or batten of a loom to re` main in one and the same position with relation to the vertical throughout the whole eX- tent of the movement of the lathe or batten in the operation of the loom. Heretofore this object has been secured by the builders of looms, it is true, but usually it has been done by constructing and mounting the lathe or hatten to reciprocate in a straight line, and in or u pon fixed supporting guides or ways. This plan presents various practical defects and disadvantages which it is my aim to avoid.

.Another object of my invention is to provide facilities for varying the position and lnclination of the arc in which the lathe-beam swings, and for making desired adjustments 1n the height of the beam of the lathe or hatten.

Another object of my invention is to provide by improved means for enabling the variation or change in the extent of the throw of the cranks on the crank-shaft, which is secured by radial adjustment of the cranks and which increases or decreases the swing of the lathe or battcn, to be compensated for by such an adjustment of the connections between the lathe or hatten and the crank-shaft as will permit the beating-up point always to remain the same, if desired.

Another object of my invention is to provide an improved center-crank and crankshaft support.

My invention consists in certain novel features of construction and combinations of parts, all as first will be fully described with reference to the accompanying drawings, and then be particularly pointed out and distinctly defined in the claims at the close of this speciication.

-tion applied thereto.

In the drawings, Figure 1 is a view in side elevation of part of a loom with my inven- Fig. 2 is aview thereof in vertical transverse section on the dotted line 2 2 in Fig. 1, looking toward the rear of the loom. Fig. 3 is a View in rear elevation of part of the lathe-beam and the supports pertaining thereto. Fig. 4 is a View in rear elevation of the intermediate or center lathebealn supports and the adjacent portion of the said beam. Figs. 5 and 6 are side and edge views, respectively, of the adjustable link or pitman.

At 1 is shown an end-frame of a loom, at 2 the crank-shaft of the loom, at 3 a hand-wheel or ily-wheel fast to said crankshaft, at 4 is shown the beam of the lathe or hatten, and at 5 one of the connecting rods, links, or pitmen by which the lathe or hatten is connected with the cranks ofthe crank-shaft. The lathebeam is pivotally supported at suitable points in the direction of its length by parallel-links or radius-bars 6, 6, which at their lower ends turn upon pins 7, 7, mounted on the loomframing. At their upper ends each pair of the said links 6, 6, is hinged or pivoted by

pins

8, 8 to

lugs

9, 9 depending from abracket 10 on which the lathe-beam is mounted.

In the construction which is represented in the drawings, the

lugs

9, 9 are formed parallel to each other and the upper ends of the links 6, 6 fit between their inner faces. The bracket 10 is formed with an L shaped portion 11 to conform to the rear side and under side of the lathe -beam, and in the vertical part 12 of this L-shaped portion 11 is formed a vertical slot 13 through which passes the stem of the bolt or screw 14 by which the lathe-beam is clamped to the bracket, while the horizontal part l5 of the bracket has a threaded hole therein,through which is passed vertically the set-screw 16 which bears by its point against the under side of the lathebeam, said screw having thereon the clamping nut 17.

The slot 13 and set-screw 16 provide for enabling the lathe-beam to be secured at any required height on the bracket. This adjustment is useful in permitting the lathe beam to be so adj usted vertically as that in narrowware looms the shuttle 18 moving on the tracks or

ways

19, 19, carried by the lathe- ICO beam shall be prevented from rubbing against the Warp-threads of either the upper plane of the open shed or the lower plane thereof, and that, in looms using fly-shuttles, the shuttle race-Way at the upper side of the lathe-beam shall move beneath the lower plane of the shed in exactly the desired relations thereto.

I make provision for varying the position and inclination of the arc in which the lathebeam moves, as follows. The pins 7, 7, are mounted in a manner to enable them to be adjusted toward or from the rear of the loom. One way of rendering them adjustable is shown in Fig. l of the drawings, in which tlgure the reduced ends of the pins 7, 7, pass through

horizontal slots

20, 20, in the parts of the'loomframing by which they are supported, and receive upon the threaded extremities thereof nuts 2l, 2l, whereby they are clamped in adjusted position.V B v shifting the pins 7, 7 toward the front or the rear of the loom various changes may be made in the angle and position of the arc through which the lathe-beam oscillates. The forward ends of the connecting rods, links or pitmen 5 are jointed to the lugs 22 forming parts of the brackets l0. In some looms of considerable width an intermediate framing-piece, called a center-frame extends parallel to the side-frames of the looms. One of these center-frames is shown at 23 in Figs. 2 and 4. Intermediate supports for the lathe-beam are also provided in such looms, one of such intermediate supports being shown in Fig. 4. The intermediate support for the lathe-beam which I employ resembles in all essential respects those which are located nearer the ends of the lathe beam, and Yis of the construction Vwhich has been described. In these looms, however, inasmuch as I prefer to place or form the intermediate crank or cranks of the crank-shaft substantially in line vertically above or with the center-frame or frames, the upper parts of the intermediate links 6, 6 are bent or off-set laterally as shown in Fig. 4, in order to permit the bracket l0 to which a pair ot such links are pivoted to be placed vertically above the center-frame, at the side of which the said links are pivoted.

To permit the extent of the sweep of the lathe-beam to be varied as desired, I connect the rear ends of the pitmen 5 to cranks of variable throw. Thus, as customary, I connect the rear-ends of said pitmen to pins 24 which are secured to parts carried by the crank-shaft with capacity for radial adjustment relatively to the said shaft.

In Fig. l I have represented one of the crank-pins as mounted in a slot 25 in one of Y Ythe arms ofthe hand-wheel 3.

hold the parts together in an adjusted posil tion. Y

In order to permit of the use ot adjustable intermediate or center-cranks I provide as follows. The crank-shaft 2 I form in sections 31, 32, placed in line with each other, and upon the proximate ends of the sections Isecurely fix crank-arms 33, 34, each of which is radially slotted at 35. As shown clearly in Fig. 2, I iit into the

slots

35, 35, at the required distance from the axis ot' the crankshaft, the reduced

ends

36, 36, of a crank pin 37, and secure the said crank pin in its position of adjustment by the

washers

38, 38 and

nuts

39, 39 which are placed upon the threaded extremities of such crank-pin. I support the proximate ends of the sections 3l, 32 in bearings carried by the center-frame, the parts being so disposed, preferably, as that the center-frame and the center-crank shall be in line with each other vertically. The said bearings are formed in

split boxes

40,41 which receive reduced

portions

42, 42 formed on the sections 3l, 32. The lower part of the box 40 is formed in one with an upwardly extending curved arm or bracket 43, having a plate or web 44 which is secured by bolts 45 and nuts 46 to the web of the center-frame. The curved arm 43 projects laterally in one direction from the center-frame a sufficient distance to clear the crank-arm carried by the section ot' the crank-shaft which it supports. rlhe under part of the split box 4l is formed with a web or plate 4l which is clamped by bolts 47 and nuts 48 to the curved arm 49 which is cast in one piece with the center-frame and projects to the side 0pposite to that toward which the curved arm 43 projects. The upper end of the curved IOO IlO

arm-49 is formed with a flange or lip 50 which -Y lits within a notch 5l that is formed in the depending plate or web 41 of the split-box 4l. This construction of the supports for the proximate ends of the sections of the crank-shaft holds the same securely and fixedly in proper position relatively to each other, and the bearings are not liable to work loose. Moreover the strain and weight are uniformly distributed on both sides of the center-frame and the resistance which in the working ofV the loom is offeredto the rotation of the center-crank is exerted in the vertical plane of the center-frame and is not likely to rack the parts loose.

I claim as my invention- I.
