CHARLES H. JOHNSON, OF SALISBURY, NORTH CAROLINA, ASSIGNOR 0F ONE-THIRD TO GEORGE O. LIIE AND ONE-THIRD TO PAUL KI DRY, BOTH OF LANDIS, NORTH CAROLINA.
DRAWING-ROLL MECHANISM FOR SPINNING-FRAMES.
T01 all whom it may concern:
Beit known that I, CHARLns H. J OHNSON, a citizen of the United States, residing at Salisbury, in the county of Rowan and State of North Carolina, have invented certain new and useful Improvements inDrawing- Roll Mechanism for spinning-Frames, of which the following is a specification.
This invention relates to spinning frames and has for-an object to provide a drawing roll mechanism embodying new and imvide a drawing roll supporting mechanism wherein the bar may be raised bodily from its operative position upon the stand carrying therewith the top. rolls without disturbilig the tension.
A further object of the invention is to provide a drawing roll mechanism wherein the top rolls may be raised together with the bar from their engagement with the bottom rolls without removal from the bar or the relieving of the tension therefrom. It is well known that in drawlng roll mechanis'msfof the :usual and ordinary type the top rolls are carried in'a bar hinged to the stand and tension is applied thereto from a weight hinged to the stand by a leverand with connecting means extending upwardly throughthe structure engaging the bar. I To raise the bar and the top rolls therewith it is therefore necessary to disconnect the tension' weight or transmission mechanism in many instances to remove the top rolls from the bar to prevent their falling and being damaged when the bar is lifted backwardly. The "present'invention involves means for maintaining the rolls in their journal bearings inthe bar whenthe bar is raised with the tensi'oning mechanism employed to main-" tain the rolls in such position and to restore the exact adjustment of tension when the bar is again returned to operat ve relat on to the stand.
Withthese and other objects in viewthe invention comprises j certain novel units,
parts, elements,,combinations', arrangements, mechanical moijtements and functions, as disclosed" in the draw ng, together Wltlrmchanicalequivalents thereof, as will be hereinaf'ter more fully described and clalmed.

Patented Nov. 8, 1921.
Application filed May 28, 1921. Serial No. 473,552.
In the drawing:
Figure l is a transverse sectional view through a spinning frame drawin roll mechanism showing the parts in full line in operative positionand in dotted lines with the bar turned backwardly.
Fig. 2 is a plan view taken somewhat at an angle, as indicated by the arrow 2 at Fig. 1, said figure also showing line 11 as the plane of Fig. 1. l
Fig. 3 is, an enlarged detailed sectional view taken on line 3-3 of Fig. 2.
Fig. {l is a perspective view of the tension spring.
Like characters of reference indicate corresponding parts throughout the several views.
The improved drawing roll mechanism, which forms the subject matterv of this ap plication, comprises a stand indicated as an entirety at 10 of substantially the usual and ordinary type with'tlie bottom rolls 11 jour naled thereon and therein in substantially the usual and ordinary manner.
Pivoted upon the stand 10 is the top bar 12 which in general shape is substantially similar to the usual and ordinary top bar and in which is journaled the to) rolls 13, also of substantially the usual an ordinary y In the usual top bar of a drawing roll mechanism the top rolls 13 are journaled by slots are closed, as indicated at 14, whereby the trunnions 15 may engage the bridge piece 14 spanning the-lower part of the slots 16 so that when the top bar is raised the trunnions will engage this bridge piece and will raise with the top bar. It will be noted especially from Fig. 3 that this bridge piece 14 is so positioned that when the device is in operative positionwith the top rolls in engagement with the bottom rolls the trunnions do not engage this bridge piece but are free to float in the slots 16 as in the ordinary construction and that the bridge piece is employed only to prevent the .dis-
raised. To maintain the bar in operative position relative to the stand a latch 17 is employed in the form of a spring which is secured to the stand and extends upwardly between the rolls, both the lower rolls and upper rolls, and hooks over the top of the bar when the bar has been moved downwardly to operative position.
Tension is applied to the top rolls by the use of the saddles 18 and 19 of substantially the usual and ordinary type but instead of applying the tension thereto by means of a weighted lever, as is ordinarily done, a spring-2O is employed having a bifurcated end 21 engaging over the adjusting screw 22, ordinarily found in the saddle construction. To effect a tension upon the spring a bent finger 23 is rigidly attached to the bar at the rear of the bank of rolls under which the spring passes to engage the extremity of-an adjusting strut 24:. This engagement may be in any approved manner but is preferably produced by providing the spring 20 with a perforation ,25 to pass over the threaded extremity'26 of the strut 24: and bear upon the shoulder 27 ,A keeper in the form of a nut 28 is preferably employed for upon the threaded extremity .26 simply for the purpose of retaining the spring 20 against displacement. The strut 2 1 is carried by an ofiset 29, preferably, though not necessarily, cast integral with the bar 12 and is :adjustedin any approved manner, as by the nuts 30 and 31. It isobvious that if the strut 24: is raised by the manipulation of the nuts 30 and 81 the tension of the spring 20 will be increased, which will be trans mittedto the top rolls 13 through the saddles 18 and 19. A tension so acquired will, of course, be maintainedby employing the nuts 30 and 81 as lock nuts, each stressing against the other.-
It will be obvious, therefore, thatthe tire combination applied to the top rolls is carried by the bar which may be disengaged by manipulating the latch 17 and lifted and V swung backward as, for instance, to the dotted line. position shown in Fig. 1, without displacing the top rolls or interrupting the tension so that when the bar'isagain returned to operative position and forced downwardly and latched the acquired tension-will be available. g
This arrangement eliminates the necessity of removing all of the top rolls from the bar when the bar is to be raised and maintains all of the parts, including the saddles, in position during such raising and any operation which may be performed uponthe;
' lower rolls or to the thread between the rolls.
In operation the device will function exactly as an ordinary drawing roll mechanism, as when in operative position the re; lation and function of the parts do not differ in any particular from the usual and ordinary drawing roll mechanism.- The is included economy in that it is a saving of time as well as a saving of rolls, as they are not damaged by removal and engagement with extraneous matter, as-is usually the case.
I claim: 7 1. A drawing roll mechanism comprising the combination with a stand and a bar hinged thereto of means to support the top rolls in the bar and means carried wholly by the bar for exerting tension on the rolls.
2. In a drawing roll mechanism the combination with a stand and top bar pivoted thereto of journal bearings'formed in the bar proportioned to support the top rolls therein and-atop roll tension mechanism carried" wholly by t'he bar.
3. A drawingroll mechanism comprising in combination with a' stand and a bar pivoted thereto, a plurality of top rolls,
means carried by the bar to support and journal the top rolls and means carried by and movable with the bar for exerting'tem sion upon the top rolls.
4;. A drawing roll mechanism comprising the combination with a stand, a top bar pivoted thereto, and top rolls carried by the bar, of journals carried by the baradaptecl to maintain the top rolls in journaledrelation'theretoaa' spring carried by the bar and movable, therewith, means employingthe stress of the springas a tension upon the top rolls 'and means to'vary the tensional efii ciency of the spring. l
