G. PFEIFFERJ SPRING STAND Fda LOOMS.
APPLICATION FILED .IULY3I. 1917- 1381365. Patented Oct. 8, 1918.
lllll GEORGE PFEIFFER, 0F PROVIDENCE, RHODE ISLAND, ASSIGNOR TO CROMPTON & KNOWLES LOOM WORKS, OF WORCESTER, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS.
SPRING-STAND FOR LOOMS.
Application filed July 31, 1917.
To all whom it may concern:
Be it known that I, GEORGE PFEIFFER, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Spring-Stand for Looms, of which the following is a specification.
This invention relates to a spring stand for looms particularly designed to engage and position the lower ends of the harness springs used in a dobby loom.
The upper ends of these springs commonly engage hooks inserted in the lower bar of each harness and the longitudinal position of these hooks in different sets of harnesses is subject to considerable variation.
It is the general object of my invention to provide an improved spring stand by which the lower ends of the springs may be sesurely held in position and which may be conveniently adapted for use with different sets of harnesses.
A feature of importance relates to the provision of a spring stand entirely supported by the 100m frame and requiring no separate attachment to the floor.
My invention further relates to certain arrangements and combinations of parts hereinafter described and more particularly pointed out in the appended claims.
A preferred form of my invention is shown in the drawings, in which Figure 1 is a front elevation of certain parts of a loom, with my improvedspring stand attached thereto;
Fig. 2 is a plan view of my improved spring stand, partly in section, taken along the line 22 in Fig; 1, and
Fig. 3 is a sectional elevation of the spring stand taken along the line 3 -3 in Fig. 2.
Referring to the drawings, I have shown part of a loom frame 10 of a usual type in which harnesses 11 and 12 are supported by dobby-actuated levers or jacks 13, to which they are connected by cords or straps 14. The lower bars of the harnesses 11 and 12 are provided with hooks 15 to which are connected the upper ends of the harness springs 16. The lower ends of the springs 16 are Specification of Letters Patent.

Serial No. 183,762.
held by hooks 17 arranged in series in bars 18 secured to upwardly proiecting lugs on collars 19 adjustably mounted on a pair of parallel rods or tubes 20. The rods 20 are firmly held in a depending casting or frame 21 bolted to a bracket 22 secured to the crossgirt 23'forming a part of the loom frame 10.
The parts are so designed that the rods 20 are supported slightly above the floor upon which the loom rests. The spring stands are readily adapted to use with different sets of harnesses by sliding the collars 19 and bars 18 in one direction or the other along the rods 20.
I have thus provided an extremely simple and convenient device for supporting the lower ends of the springs in any desired longitudinal position and at the same time I avoid the necessity for separately securing any part of the device to the floor.
Having thus described my invention it will be evident that changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of my invention as set forth in the claims, and I do not wish to be otherwise limited to the details herein disclosed, but what I claim is 1. In a loom, in combination. a loom frame, a casting rigidly supported thereby, a pair of parallel rods mounted on said casting, collars longitudinally adjustable on said rods, and bars connecting said collars in pairs and having each a plurality of springattaching devices thereon.
2. In a loom, in combination, a loom frame, a depending casting rigidly supported thereby, a pair of parallel rods mounted in opposite ends of said oasting, collars longitudinally adjustable on said rods, upwardly projecting lugs on said collars, a cross bar secured to each pair of said lugs, and a plurality of hooks on each bar adapted to engage the lower ends of a series of har- .ness springs.
GEORGE PFEIFFER.
