ADJUSTABLE CLOTH ROLL ARBOR 2 Sheets-Sheet Filed April 5, 1956 mw 9v I wml? U @maze BY "d 3M@ Unite This invention relates to an adjustable cloth roll rod and more specifically comprises an adjustable arbor for rotatably supporting a roll of material, and especially a roll of cloth for spreading machines.
The principal object of this invention is to provide an adjustable arbor whereby a roll of material such as cloth may be readily journaled for winding or unwindmg the same.
A further object of the invention is to provide an adjustable arbor in conformity with the preceding object which may be readily inserted into a crushed or distorted spool upon which a roll of material is wound for journalling the same.
Yet another object of the invention is to provide an adjustable arbor in conformity with the preceding objects which will automatically center itself in a spool whereby to support the latter for rotation.
Still another object of the invention is to provide an adjustable arbor in conformity to the above mentioned objects having an improved means for manually expanding the arbor into tight centered supporting engagement with a spool of a roll of material.
And a iinal important object of the invention to be specifically enumerated herein resides in the provision of an adjustable arbor for rolls in accordance with the above mentioned objects wherein the highly advantageous and improved means is provided for selectively expanding and retracting lingers from the arbor whereby to center the latter in a spool; together with means for limiting the extent of the expansion and contraction of such fingers.
These, together with other objects and advantages which will become subsequently apparent, reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein4 like numerals refer to like parts throughout, and in which: I
Figure 1 is a perspective View showing the manner 1n which the improved arbor `of this invention is associated with a cloth spreading machine for supporting a roll of cloth thereon;
Figure 2 is a view in vertical longitudinal and central section through a roll of cloth showing the manner in which the expansible arbor is centered and secured therein, a part of the arbor being broken away and shown in section;
Figure 3 is an enlarged detail view showing in vertical section a portion of a spool in which the arbor is secured, and showing certain details of the arbor construction including the expansible fingers and their mounting and actuating means;
Figure 4 is a horizontal sectional detail View taken substantially upon the plane indicated by the broken section line 4 4 of Figure 3 and showing, in particular, the mounting of the ngers upon the arbor;
Figure 5 is a detail view in vertical longitudinal section v of an end portion of the arbor; and
tates Patent Figure 6 is a detail view in vertical longitudinal section of the other end portion of the arbor and of the adjusting handle thereof.
Shown in Figure 1 is a conventional form of cloth roll spreading machine indicated generally by the numeral 10 and by means of which-a roll of cloth 12 is adapted to be unrolled. As shown best in Figure 2, the roll of cloth is provided with a central spool 14 upon which the material is wound, while indicated generally by the numeral 16 is the adjustable arbor in accordance with this invention for engagement in the spool for rotatably supporting the spool and the `roll of cloth.
Although the invention has been specifically illustrated in connection with a cloth spreading machine for handling a roll of cloth, it is to be understood that it is also useful as to certain of its principles and features of construction for rotatably supporting the spools upon which other materials may be wound.
Referring now more particularly to the accompanying drawings, it will be seen that the adjustable arbor of this invention consists of a hollow tube 20 of any suitable material and which constitutes the major and central portion of the arbor. As shown in Figures l and 2, the opposite ends of the tube 20 are provided with diametrically reduced extremities or end portions 22 and 24. These end portions constitute journal or bearing means whereby the arbor and the roll of material carried thereby may be rotatably mounted upon supporting rollers such as the rollers 26 of the spreading machine 10. Conveniently, one of the end portions, such as that indicated at 24, may be provided with a circumferential or annular groove 28 for reception in one set of rollers 26 whereby to retain the arbor against axial movement upon the spreading machine during rotation of the arbor and roll 12 thereon.
As shown best in Figure 5, the end portion 22 may include a cylindrically enlarged body Sti received within the end of the tube 20 and removably secured thereto as by fastening screws 32. The reduced end portion 22, with its conical surface 34, constitutes a guide means whereby the end of the arbor may be inserted into a the end 22 in Figure 5 to the end portion 24.
Referring now especially to Figures 2 4, it will be apparent that the tube is provided with longitudinally spaced sets of circumferentially spaced longitudinally extending slots 40, three such slots being illustrated for each set, and two such sets being shown. From Figure 3, it will be seen that each of the slots is provided at one longitudinal end thereof with an inclined cam surface 42 for a purpose to be subsequently set forth. A fastener means comprising the cylindrical body 44, having an axial bore 46 therethrough, is slidably received by means of this bore upon a rod 48. A setscrew 50 or similar means may be provided for securing the body 44 rigidly upon the rod in axially adjusted position thereon. Projecting inwardly from an appropriate portion of the tube 2li is a pin or screw S2 adapted to engage one end of the body 4d and thus limit axial travel of the body and of the rod in one direction within the tube. A plurality of radially extending bifurcated ribs 54 are formed upon the body, there being provided one such bifurcated rib for each of the slots itl in the tube. By means of pivot pins 56 the inward ends of blades or fingers 58 are pivoted to the bifurcated ribs. These fingers have upon their radially inward edge a cam surface 60 which is adapted to be slidably engaged to the cam surface 42 of the Slots, while the outer ends of the fingers are provided with terminal portions 62 which, when the lingers are extended radially as set forth hereinafter, are adapted to securely engage the interior surface of the spool 14 to thus center and anchor the arbor thereto.
By means of tension springs 64 the fingers 58 are resiliently urged radially inward into their collapsed position, causing the cam surfaces 60 of the lingers to press against the cam surfaces 42 of the slots.
As so far described, it will now be understood that when the rod and the bodies 44 which constitute fastening means for the lingers 58 are moved towards the right, the sliding engagement of the cam surfaces 60 and 42 will cause the lingers to be projected or extended radially from the slots of the tube and into centering and anchoring engagement with the interior of the spool 14. As the rod and associated members are moved towards the left, the spring 64 will cause retraction of these lingers, such axial movement being limited by the stop pin 52 previously mentioned.
It is to be understood that any desired number of sets of the bodies 44 and of the pivoted lingers 58 may be provided. Two such sets are found satisfactory for most purposes, although for longer spools three or more sets of lingers and fasteners 44 may be desirable.
An actuating means is provided for imparting axial movement to the rod. As will be readily apparent, the engagement of the lingers in the slots will prevent relative rotation between the fingers, rod, fasteners 44, and the tube.
Referring now especially to Figure 6, it will be seen that the end portion 24 of the rod 20 is provided with an integral annular liange 70. A split gland 72 surrounds the portion 24 and is adapted to abut the flange 70 and is detachably secured, as by fastening bolts.74, to one end of a cylindrical handle 76. The latter is provided with an internally threaded bore 78 which, at one end, terminates in an enlarged counterbore 80 receiving the flange 70 for free rotation thereon but preventing relative axial movement of the handle with respect to the extremity 24. Integrally formed upon the end of the rod 48, or otherwise lixedly secured thereto, is the externally threaded portion 82 which is received in the screw threader bore 78. It will thus be seen that upon rotation of the handle 76, axial movement will be imparted to the rod 48, since the latter is held from rotation by the above mentioned association with the fastening means 44 and the fingers 58.
The end of the bore 78 is closed by a handle 84 which is detachably secured thereto, as by bolts 86.
It will thus be seen that by means of the handle, axial movement may be imparted to the rod 48 to thereby extend or retract the fingers of the arbor, thereby facilitating the application of the same to the spool of a roll of material, and the removal of the arbor from the same.
The foregoing is considered as illustrative only of th principles of the invention. Further, since numerous modications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modilications and equivalents may be resorted to, falling Within the scope of the invention as claimed.
