mass PREVENTER. I

. Application filed April 29, 1926. Serial No. 105,461.

This invention relates to smash preventers for looms of that type not equipped with brakes, and has for one of its objects the provision. of a device of this character which shall be adapted to effect the throwing off of the shipper and the stopping of the lay whenever the respective shuttle boxes simultaneously contain a shuttle.

A further object of the invention the provision of a device of the character stated which can be readily applied to the breast beam and lay of a loom without making any alterations in these or the other parts of the loom.

With the foregoing and other objects in View, theinvention consists of the novel construction, combination and arrangement of parts hereinafter fully described and claimed, and illustrated in .the accompanying drawings, wherein: u i r Figure 1 is a top plan view illustrating the application of the smash preventer to the breast beam and lay of aloom,

Figure 2 is a sectional view taken on the Figure 7 is a sectional view taken on the vertical plane indicatedby the line 7-7 of Figure 1. i

Corresponding and like parts are referred to in the following description, and designated in the several views of the accompanying drawings, by similar reference characters. I

In the drawings. 1 designates the breast beam, 2 the lay and 3 the shuttle boxes of a loom. vThe rear walls and swells or binders of the shuttle boxes 3 are designated 4 and 5,

respectively. .As these parts are of v well known construction a further description thereof is deemed unnecessary y In accordance with my invention, a shaft Storming a part ofthe shipper controlling mechanism of the loom, is supported from p the breast beam by bearing brackets 7 i arm 8 extending "a' rearward direction therefrom,'is secured: tothe shaft 6 by set screw 9 and has 'an'arcuate rear endportion "8. ,AlJOISlOIl spring 10 s mounted on'f the shaft 6 and is connected at its ends to one of ]-the bearing brackets 7 and a collar 11 mounted onthe shaft and secured thereto by a set screw 12. Thespring 10 tends to rotate the shaft 6 in a direction to exert a constant upward pull on the, arm 8. i A bracket 13 having a rearwardly extending horizontal member 13) and a vertical member13 is sec-ured to'the breast beam 1 for vertical adjustment with respectthereto by screws 14-. which engage the breast beam and passwthrough vertical slots in the bracket member'13". A vertically disposed arcuate lever 15'isconnectejd at itslower end to the bracket-member 13. for movement about a horizontal axis 16, and is provided intermediate its ends with a horizontallydisposed pinjl7 which'conta-c-ts with theupper convex edge of the [curved endportion8 of the lever 8. Thelever 15 is limited'in its upward movementby a stop 18 and in its downward-movement by a stop 18 the stops being carried by and extendinghorizontally from the bracket member 13. Alatch 19 is pivoted intermediate its ends as at 20 to 'the upperportion of the lever 15, and its upper free end is yieldingly supported above the upper free end of the lever 15 by a spring 21. The movement ofthe latch 19in an up ward direction under the influence of the spring 21 is limited by a shoulder 21 'formed on the lever 15 in position for engagement by the lower free end, oflthe latch.

A shaft 22 carrying rearwardly extending daggers 28, is supported from the breast beam 1 by bearing/brackets 24. A rear- 7 wardly directed arm 25v is secured to the shaft22 by a set screw 26, and is connected to the lever 15 by an elbow lever 27 and a link 28, ,The lever 27 is mounted upon the pivot'16 offthe lever 15, and an arm thereof is provided with a head 29 having an arcuate slot30 through which passes abolt 31 carried by the lever 15. The levers 15 and 27 are arranged in; parallel relation, andthe stated connection between the same permits their angular relation to be varied. The link 28 is engaged with one of a series ofopenings 32 in the lever 27 and passes freely through the free end ofthe arm 25, and a spring 33 is mounted on the link between a nut'34 on the latter and between the arm 25; The

I ositions in which the i are shown in Fi ures openings 352 permit the link 28 to be ad 2 and? lVhenthe lever is'actua't edin a downward and rearward direction it will,

due to the connection established between it and-the shaftb by means of the arm 8 and pin 17, and due'to the connection established between "it and the shaft 2'z2by the lever'27, link QS and arm 1'25, roclrtlie shafts in directions tothrow off the shipper and raisethe dagge'rsQZlinto operative position, with the result that the loom will stop and the lay held against forward movement. lVhen the fleve'r15 released, the spring 10 and daggers'23 will'rturn'the parts to their normal positions.

i Means for actuating the lever 15 whenever the respectiveshuttleboxes 3 simultaneously contain a shuttle, is carrietl'by theilay 2 and comprises a lever 35 extending forwardly and rearwardly of thelay and connected to the under side thereof at a point intermediateits endsby movement about a horizontal axis36. The pivot 36 is carriedby a bracket 37 which isprovi'ded at the rear side of the lay2 in a vertically disposed boss'38. A vertical rod, 39. is slidably supported by the boss 38. spring 40 exerts a constant downwardpressure on the rod 39, and the downwardmovement of the'ro'd is limited by anut ll. The-rod'39 is. pivotally connected as at liZ'to the rear end of the lever '35, and due thereto the latter is normally helfd in a-suhstantially horizontal position. When the lever 35 is in this position, a'hook 43 carried by theforward end of the'lever is supported out of the,path of the front end'of the latch 19. A bar 44c extending longitudinally of the 'lay 2-is pivoted intermediate its ends to the rod 39 as at 45. The ends-of the bar M: pass through ertical .slotsttl in'brackets 47 which are. secured to ib elow the ends of the bar's It. Upwaiidly and rearwardly extending arms'5l are secured at anddepend from the lay 2. Shafts 48 are supported at the front side of-the-lay 2-by brackets 49. Downwardly and rearwar'dly extending arms 50' fixed attheir front ends .tothe shafts d8 have their rear ends disposed their lower ends to the shafts4l-8 and are provide d with angular upper terminals 52 which contact with the swells or binders 5 of-the shuttle boxes 3. Springs 53 mounted on the shafts 48; connected to collars 5% on the shafts and contacting with the under side -of the lay 2, exert constant downward pressure on the arms 50 and constant rearward :grcrstops 55. 'from the lower e'dggesof the bracket members '56" and sem'e to guide the-free ends of 105 P essure -'on the arms "51 in :order to maintain the former out of contactwith the bar 44 and the latter in contact with the swells or hinders "of the shuttle boxes 3.

When the arms 51 are simultaneously moved forwardly, as will occur whenever a shuttle is in each of the boxes 3, the arms 50 a're'swung; upwardly. As the arms 50 are leverin a direction to depress'the front end thereof and carry the hook 43 into the path of the fr'ont'end of the latch 19. with the result thatthehookwill contact withthelatch during the backward.movement of the lay 2. This actuatest-heshipper throwing off mechanism of wliichthe shaft '6 forms apart and as the @result'stopsthe-operation of theiloom.

At the same time the daggers 23 are raised into active position so'asto enable them to contact with stops 55 during the forward movement of the lay whereby to effect the V stopping of'the motion of the lay. The dagger stops55 are removably secured mbraclr ets 56'by means of set screws'57. The brackets56 are of angular formation presenting horizontal members 56 contacting with the under side of the lay 2 and constitutingwear plates. brackets 56-contact withthe "front side o'f'the lay 2. Thebr- acket members 56 and 56 are conne'cted with their adjacent edges in relatively space'd relation by strap'lugs58 which are of angular formation and which in conjunction with theifront edges of the bracket members 56 constitute supportsfor theTdag- Guides 59 extend forwardly the dangers 23 intoongagement with the stops'55-when the dangers are in raised or active position. The' brackets 56 are secured inplace by screws 60.

From the foregoing description, taken in connection with the accon ipanying drawings, it-should be apparent'that the smash preventer will not stop'the loom duringthe normal operation thereof, that it will imme- -diately'throw olfthe shipperwhenever the respective shuttle boxes simultaneously contain a shuttle. and that it will at the same time stop the movement of the lay. lVhile I have described the principle of operation of the invention. together with the structure 129 whichI now consider to be the' best embodinent thereof, I desire to have. it lunderstood that the dev1cesh0wn1s merely illustrative and that such changes may be made when (lBSlIQd as are within the scope of thejinvention asclaimed.
