Description

L drawing mecha SQ n'sm of u spinning "mme that embodies my nventon.

The nwnupis shown in drawing; as appli/ed o a dymvng mechanism provided with @ndi/ess b2 @mum-y the roving, bu 0nd tina: it may be applied wa.; to any syS-zm of gyn will,

standard ik@ :md mf sbe 7@ easily i and the Weight 25 and hook 24 in the cyl* inders 5 and l7 being removed. lt will he understood that when these two cylinders are removed the pressure plate 8 may slip down thus permitting the lever 16 to fall upon the adjacent parts of the frame. This action is increased hy the presence of the weight 25. The end 17 of the lever is downwardly curved and reduced so as to receive a pivot upon the screw eye 18, while projections 19 and 20 extend respectively upwardly and downwardly from the end 17 in order to engage the sides of the eye 13 to prevent accidental displacement of the lever end from the eye when the same. is allowed tc fall. The projections 19 and 2O are such, however, as not to interfere With the removal of the lever lrfrom the fulcrum eye when this is desired The removal of the lever may loe4 :accomplished hy swinging the same forwardly about the eye'V in acountercloclwise direction which causes Athe lower projection 20 to swing througlrthe lower portion 'of the eye. The loop llon the lower end of the tie rod 13 engages ahoutthe curved portion of the lever 16 and at the opposite side of this curved portion lis a lug 22 extending downwardly from the lever and forming with the downwardly curvedend 17 a recess 21 from which the loop le may not escape even when the tie rod 13 falls down loosely. The lug is of greater length than the opening of the loop 1.43. which prevents the loop from sliding'L alimg' the lever.' rlhe free end of the level' 16 is enlarged at the point where the hook 24e engages it so that the free end of the hook may not engage the plate 26 so as to avoid the 4likelihood of the weight'Q becoming detached from the lever. lt canl be seen therefore that with the use of the present invention the removal .of the upper-,cylinders 5 and 7 is greatly eX-v pedited, and furthermore the pressure Ine/chi anism is always retained in instance,l a

.recess serving as a .guide and vrcleaning cylinder; a tie rod Signed at Barcelona,l ,Barcelona and Kingdom of Spain, this 9th,

positionftojct in 'itsnorinal capacity when these cylinders are replaced. v

In the drawings the feeding cylinder 3 is shown to be of comparatively great diameter in order to exert a pressure upon the companion cylinder 2; however, it will be understood that a cylinder of smaller size could also be employed and he weighted by proper pressure mechanism7 such as, for

tension piece 1/0 of the pressure bar 8.

rlhe pressurehar 8 may be arranged as shown in the drawings to provide a circu- 4 part bearing upon the cylinder" 3 which receives its pressure from thel exl' same manner a second fitting might he pro# vided to receive a second cleaning cylinder for the cylinders 3 and 5. n

lt is obvious that various changes-and modifications .may he made in the details .of construction and design of the above specifically' described embodiment of this invention Withoutl departing-` from lthe spirit thereof, such changes and modifications loe-v ing restricted onlyl lowing claim.

l claim: ln a drawing mechanism having upper and lower pairs of drawing cylinders, a pressure bar hearing upon said upper cylinders to fulcrum about either of such cylindersvto permit of the removal of the other cylinder, said press-ure bar provided with a handle forming at the same time a circular support for'a pivotally conneet-edv to the .pressure har, and Weighted means connected'to the lower portion of the by the scope of the foltierod 'and eX tine a ressure on the res an P sure bar.
