Specification of Letters Patent.
Patented Aug. 5, 1919.
Application filedAugnst 13. 1918. Serial No. 249,642.
To all whom it may concern:
Be it known that I, Bonner JAMIESON, a citizen of the United States and residentof Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Loom-Seats, of which the following description, in connection with the accompanying drawing, is a a specification, like characters on the drawing. representing like parts.
This invention relates to improvements in loom seats and the object thereof is to provide a seat for the operator of a series of looms or other machinery which will be so constructed and arranged that it .will present a firm and durable seat while in operative position, occupyinga minimum amount of space and when not in use may be folded closely against the side of the loom or other machine, thereby leaving the passage around the machine free from obstruction.
One of the objects of the present invention is to provide a loom seat which is capable of being folded against the loom frame and retained in such inoperative position and which when brought to horizontal or operative position will be securely locked in that position so that the operator can leave the seat and again resume it without the necessity of looking behind him.
A further feature of the invention consists in providing means for locking the loom seat either in operative horizontal position or in substantially vertical inoperative position whichwill prevent the seat from assuming and remaining in any intermediate position so that the loom seat when removed from operative position cannot project into the alleyway between the looms.
Another object of the invention is to provide a loom seat of the character described which will be simple in construction and of maximum strength.
Other objects and features of the invention will more fully appear from the following description, the accompanying drawings, and will be pointed out inthe annexed claims. a
In the drawings; i i
Figure 1 illustrates a. portion of a 'loom frame with a preferred form ofloom seat secured thereto, i
' Fig. 2 is a view partly in sectionon lines 2-2 Fig. 1 looking toward the loom frame.
Fig. 3 is a horizontal sectional view on line 3-3 Fig. 2, and,
Fig i is a detail sectional view through the end of the arm of the loom seat showing the locking plunger engaging the locking surface thereof.
Inasmuch as the 100m seat attachment forming-the subject matter of my invention is applicable to almost any type of loom only a part ofthe vertical portion of the loom side or frame is illustrated herein with the seat attachment secured thereto.
In the construction illustrated the l'oom frame is made. of channel or angle iron presenting a flange 2 and the bracket which supports the loom seat is so constructed as to be readily secured to this form of frame. The bracket desirably is of somewhat boxlike construction and is formed in two parts which enable it to be clamped about the flanged vertical edge of the loom frame. The main part of the bracket is of substantially L-shape, presenting walls 3 and 4 at right angles to each other, the inner edge 5 of the wall 3 being adapted to rest against the flat face of the frame 1. The other portion of. the bracket comprises a plate 6 which abuts at one end against the edge 7 of the wall 4 and has an integral offset side 8 extending alongside the flange 2 of the frame and terminating in an extension 9 which lies parallel to the side of the frame.
The plate 6 desirably is provided with lugs 10, 11 adapted to engage respectively the innerface of the wall l and the outer face of the flange 2 to position the parts of the bracket properly. The main portion 3 of the bracket and the plate 6 are secured together by a bolt 12 which extendsthrough the sameadjacent to the outer edge of the flange 2. I
In order to secure the parts of the bracket firmly together and to the loom frame, notwithstanding any inequalities which may exist in the latter adjustable means, such as one or more, thrust screws 13 are passed through the extension 9 of the plate 6 and abut against the inner side of the loom frame .1. a The wall 30f the main portion of main pertioni bruit bracket; ,Tlie; main pol?! tion of the bracket is also provided with anv face 19 which serves as an abutment toretain the seat in horizontal position as will hereinafter be more fully. explained.
- Theseat 20 n'iay be and is of the usual circular form and is carried. at the outer 'end of an arm 21 which is journaled at its nner end upon the pivotal shaft on pin 15.
The inner end of the arm 21, is. provided, with an! integral: upward and lateral extension: 22 which! when: the, seat is in horizontal positionengages the; flat. under: face L9 of the hook-like extension 18 of the member'- L71. By, constructing; the: member 17.. in arcuate form; space isprovided: which; willipermit the extension 2.2 toswing downwardlywhen the seat 20 is raisedifinto vertical or'inoperae tive; position against oradjacent the loom rame;
The inner.- end. of, the arm: 2.11 is also provided with a laterally offset portion 23 which forms an. increasedsbealiing-'area: upon th shaft; 15.- and. also provides. a, means: for locking; the seat in horizontal; or vertical positions. The extension 23- lSi provided witln ani-under-flat face 2d and; an end, fiat face 25. which, are alternatively adapted; to be: engaged; by the head; 2.6 of a' plunger 27. which ,is reciprocably; mounted: in: a. cylindrir calbore 28in the cornerportion of the main member of thebracket. The plunger. 27; def sinably. is: provided: with. a. central stem.- 29 extending centrally..- down. through: the? bore 28-, and. slid'ablyr niollntedi ini'a. bearing. 30; in the lower? end of said. bracket, the bore 28 extendingv nearly: the full; distance through the member and; terminating a, sufficient; dis? tance from the bottom: thereof:- to provide for the bearing-30s Theplunger-27J i'snorrmallyfenced: upwardly;- by. a' helical spring 311 which.- is coiled; about; the. stem. 2910f the plunger? and; restsiat itszlowerend" upon the upper-=- facegoff the bearing. 3.0.3 and? at its u ppenend. engagesvthe base of the plunger 2 Y The head: 26; ofi'theplunger thusbeing adapted; to engage eitherthe surface 24 upon the bottom of the arm 21 which: care riesthe seat 201'017 the flatface 25. at the end of said arm: is:enabled to lock the seat either in the horizontal positioni illustrated in' Fig; 1 or in the vertical position: illus trated' in dotted lines: in: said figure.
' 'When the seati's pulled--down to; hori zont'alf operative position therenot? onlyis lie-tendency of"thejseat to -move to inopera tive position-but it is locked against? such movement; whereas when: the seat is moved tover-tical' orrnoperatlve position theen' 'gage'ment of the plunger- 26 with the face 2.5; at itlieu nd of the arnr 21 effectively prevents the seat from dropping back to horizontal position.
It will thus be seen that the scat may be positively locked in either horizontal or substantially vertical position. It will be observed that the construction thus described. is of a simple character and is strong and" durable.
It will. be' understood that the particular construction disclosed herein is of an illustrative character and; is-not restrictive and that various modifications: may be made withinithe-spinit and scopeof the following claims,
