- 1,529,542 .E. F. HATHAWAY TUBE FRAME Filed June 1/1922 4 Asa Ykhkmgg separate bearing blank 6, and the slide mem The main upper end portion of the blank is bent outwardly to form parallel horizontal arms 5, between which is located a block 6, provided at its middle portion with a vertical bearing orifice in which is pivotally mounted a cooperating suspension member 7 having its upper end formed in the shape of a pointed or tapered button 8, and having its lower end provided with a short aotuat ing arm or finger 9 longitudinally slotted as shown at 10 to receive a projecting pin 11 mounted on a slide member or plunger 12, which is slidable outwardly and inwardly to one side of the pivotal axis of the member .7 and which is provided with an offset downwardly extending finger 12, whose lower portion comes opposite the line of the pivotal axis of member 7 below the level of the arm 9, and in position to beengaged by the inwardly projecting boss commonly formed at the upper end of the transfer clutch 15 which is indicated in dotted lines in Figures 1 and 3 and is of old and well known construction. r

The tension spring 14, attached to the rear end 9?, of the arm 9, with its otherend suitably secured to the main suspension arm 1, serves to normally pull the arm 9 in a contraclockwise direction as viewed in plan while allowing the arm to be shifted to the position indicated in dotted lines in Figure 4 when the transfer clutch 15 is raised and moved inwardly into operative engagement for releasing and transferring thetube frame from the carrier chains 16 the chain when in the position shown in Figure 3 which is the position both for removing the tube frame from the chain and for re-inserting it by, means of 'transfer clutches 15. In that position the actuating slide 12 has been pressed to its inmost position, leaving the head or hook portion 8 of member 7 extending lengthwise in the direction of the chain. Upon the outward movement of the transfer clutch 15, the tension spring 14:, turns the member 7 through an arc of 90 so that the head or hook portion overhangs the chain link to prevent ;its withdrawal. This outward movement of the slide 12 is limited by the abutting of the arm 12' against the inner end of the bearing block 6. 1

The simplified construction and .arrangement embodying the same principle of action is illustrated in Figures 6 to 9 inelusive.

In thismodified form of the invention the her 12, may be dispensed with and the transfer clutch 15 will act directly upon clutch-engaging means located at the lower formed is partly cut away on either side edge to form a narrow connecting portion or neck 20 leaving side wings or members 21 to be folded in as indicated. by dotted lines to lie in parallelism and to project downward to form flanges when the upper end is bent outwardly at right angles along the transverse dotted line of Figure 9 to form a supporting plate 22, which is really an ofl"-' set support for the cooperating chain looking member 7. These downwardly projecting side flanges 21, have their interior portions cut away to leave projections 23 for retaining a bottom bearing plate'24 in position to form a supportlng or positioning I bearing for the lower end of the member .7, said bearing plate 2 1 being centrally perforated in alignment with the bearingperfora-tion formed at 25 in the horizontal extension 22 of the arm. 1.

To the extreme lower end of the swivel member 27 is secured an actuating arm 26, whose forwardly exposed face is in line with an upwardly projecting pin 15 on the trans fer clutch with exposed edge, as will be seen, is laterally oifset from its central axis of rotation a distance equal to the offset distance of the pin a from the middle line of the transfer clutch. moves in on a straight line until the pin 7 reaches the position shown in dotted lines at the left of Figure 7 in which position the actuating arm 26 will be turned just as indicated in dottedlines in Figure 7. This quarter turn of the member 7 brings the longitudinal axis of the head into alignment with the carrier chain linkto permit with- The transfer clutch drawal of the locking member 7 from the.

chain or to permit its insertion therein.

A tension spring 27, engaging the opposite end of the lever 26, tends to draw itin a contraclockwise direction so as to restore the locking member 7 to locking position and keep it there until the arm.. 26 is swung around by the transfer: clutch {into releasing position. The pivotedvlocking member7 is provided with a projecting collar or shoulder 7, 90 apart to engage an up wardly projecting stop-pin 29 was to limit the rotative movement ofthe member 7 to. the desired arc of movement and prevent thetension spring from pulling it beyond its proper locking position, b

2. Tube frame suspension means embracing in its construction an upright arm firmly secured to the carrier bar of a tube frame, a swivel locking member mounted at the upper end of said arm in position to overhang the tube frame-carrier chain when in looking position, and means connected with said swlvel member arranged to be operated by the loom transfer clutch to 7 shift said swivel member to'position to permit withdrawal of the tubeframe from its carrier, substantially as described.

3.. Tube frame suspension means embracing in combination with a carrier chain, a

suspension member adapted to form a suspending connection between the chain and the tube frame, a spring-actuated slide member acting to maintain said suspension member against movement from its operative suspending position, said slide member being arranged to be shifted against the action of its spring by approaching transfer mechanism to permit release of the suspending connection in order to allow transfer of the tube frame from the chain to the loom, substantially as described.

4. The combination with a tube frame carrier chain, a tube frame transfer mechanism, of tube frame suspending means forming a releasable suspending connectionbetween the tube frame and thechain, a spring-actuated slide bolt normally acting to prevent release of such suspending connection while adapted to yield under pressure of the transfer mechanism to permit the transfer mechanism to withdraw the tube frame from its suspended connection with the chain and transfer it to the loom, substantially as described.
