UNITED STATES PATENT OFFICE LINOLEUM COILING DRUM Frank E. Maxwell, Delhi, La.
Application September 21, 1949, Serial No. 116,933
This invention relates to assemblies for handling sheet material and rendering it possible to more -easily cut the same into 4desired predetermined lengths and to coil the cut portion into a Aneat roll in confined spaces and in an eiiicient and rapid manner.
Those who have had experience handling sheet material, particularly linoleum, rugs and the like, are well aware of the fact that the cutting operation thereof `and vthe ceiling of the same into a roll for later 4use for storage or for transportation, is a somewhat difficult task because of the bulkiness of the sheet material itself. Linoleum must be handled carefully to prevent tearing and other damage thereto kand in the absence of mechanism to facilitate the cutting and rolling action', a tremendous task is presented.
Another important object of this invention is to provide an elongated drum for receiving and coiling a length of sheet material thereabout, the drum being rotatably mounted and provided with a specially formed clamp 4that releasably holds the sheet material to the drum when theV coiling action takes place.
A further object of the lpresent invention is to provide a drum having a rotatable shaft, the shaft and the drum being relatively rotatable and the shaft in turn being provided with a clamp disposed adjacent the outermost surface of the drum for movement to and from a position grasping the sheet material to be rolled as the shaft is rotated relative to the drum.
A still further object of this invention is Ato provide a sheet rolling assembly having a hollow drum provided with at least one opening therein and a clamping member swingably mounted within `the opening, there'being linkage interconnecting such clamping member with the drum shaft for movement of the clamp to and from an operative position as the shaft is rotated relative to the drum.
Other more minor objects will be made clear or become apparent as the following specification progresses, reference being had to the accompanying drawings, wherein:
Fig. 1 is a top plan View of a linoleum measuring and cutting table made in accordance with my present invention, parts being broken away and in section to reveal details of construction.
Fig. 2 is a side elevational View thereof.
Fig. 3 is a substantially central, transverse, cross-sectional View taken on line lII-III of Fig. 1 looking in the direction of the arrows.
1 Fig..4 is an venlarged transverse, cross-sectional view-taken online IV-IV of Fig. l. -V
2 Claims. (Cl. 242-74) Fig. 5 is an enlarged fragmentary, detailed, cross-sectional View taken on line V--V of Fig. 4.-; and l Fig. 6 is a transverse, cross-sectional view similar to that shown in Fig. 4 but illustrating a modied form of drum assembly.
In Figs. l, 2 and 3 of the drawings, there is illustrated a table broadly designated by the numeral I0, which may take any form desired differing from that chosen for illustration.
Table I D is provided with a plural-ity of legs I2 supporting a top I4 that constitutes a pair of substantially identical sections I6 and I8. A continuous, down-turned flange 20, depending from r the top I4 and connected with the 'legs I2, serves as additional supporting means and as supports for certain of the parts hereinafter to be described.
'The proximal edges of the sections I6 and I3 of top I4 are spaced apart and the uppermost marginal edges adjacent such space are provided lwith metallic cutting plates or strips 22 and 24, respectively. The proximal longitudinal edges of strips 22 and 24 are, likewise, spaced apart, and such strips are held in place upon the top -I4 through the medium of a vplurality of screws or the like 26.
An elongated cutter blade 28 has its lowermost longitudinal edge sharpened and extends transversely across 4the top I4 for movement to and from a position between the proximal edges of strips 22 and 24. Flange 20 carries an upstanding bracket 30 adjacent one end of the strips 22 and 24 that has a pair of spaced, transverse pintles 32 for slidably receiving a vertical bar 33 having a slot 35 therein. Bar 33 is disposed between the legs of -bracket 3), and the pintles 32 pass through slot 35. The uppermost end of bar 33 is provided with a pin 3l for receiving bifurcated end 39 of the cutter blade 28. The opposite end of blade 28 extends .beyond the proximal edge of the table I 0 and is swung to and from the operative position in a manner illustrated by dotted lines in Fig. 3 through the medium of a handle 34 pivotally secured as at 36 to an upstanding bracket 38 on'the flange 20 in opposed relationship to bracket 30.
A short link 39 pivotally interconnects the handle 34 intermediate the ends of the latter and the proximalend of the cutter blade 23.
A coiling assembly for linoleum 40 or like sheet material, is broadly designated by the numeral 42'.'V 'Assembly 42 vincludes an Velongated drum 44 that in turn constitutes a pair of spaced-apart, elongated sections that are substantially identical andarcuate in cross-section. -Suchsections are:
designated by the numerals 46 and 48 respectively. Accordingly, a -pair of diametrically opposed, elongated slots 58 and 52 are formed in drum 44 and extend longitudinally the entire length thereof.
The two link sections 45 and 48 are held together by a plurality of spaced transverse partitions 5G that are rigidly secured to the innermost faces of sections 45 and 48 by welding or other suitable fastening means. Each partition or reinforcing member 54 is provided with a pair of diametrically opposed, semi-circular notches 55 and 53 that register with the periphery of the disc-like partitions 54. As is clear in Fig. 4 of the drawing, the notch 56 registers with the slot 5f! and likewise notch 58 is in direct registering relationship with the opposed slot 52. Each partition 54 is also provided with a centrally dis'- posed opening 68 for loosely receiving an elongated shaft 62 that extends entirely through the drum dit and projects therebeyond at each end of the latter. One of the projected ends of the shaft 52 is in turn provided with a manually operable crank 64.
The coiling assembly 42 is supported by the table i in spaced relationship above the top lll thereof at either side of the cutter blade 28 as desired by two pairs of opposed up-standing arms 13 and 58. The four arms S6 and are identical and have one end thereof pivotally secured asat 'it to the ange 20 of table |5 and are supported in an inclined position as shown in Fig. 2 by a stop 'i2 on flange 28.
The uppermost end of each arm 56 or 53 is notched as at-lll for receiving the projected ends of the shaft 62. It is thus seen thatV with shaft 52 resting loosely in the notches l, the same may be rotated freely through manipulation oi crank 5d and it is further seen that the drum l may be rotated relative to theA shaft 52.
A pair of elongated clamping members 'i5 and i8 respectively, of identical character are provided for slots 5|) and 52` respectively. The elongated clamps. 'l' and i8 are each provided with a dat, innermost face 8B and a transversely arcuate uppermostv face 82, faces si? and 82` converging into a relatively thin marginal edge portion 84 that is disposed in direct underlying relationship to the marginal edge of drum section i3 adjacent slot" 5ft or 52, as the case may be. Such edges t?, of' the' clamps l5 and i8 are swingably secured to the drum section d8 through the medium of any' suitable hinge, broadly designated by the numeral 66. It is preferable that the hinge 85 extend the entire length of the clamps it or i8 and the drum section 158.
The shaft 52 is* provided with a number of brackets 88 rigidly secured thereto and in spaced relationship throughout the length thereof. Each bracket BS-has a laterally extending arm 9i] that is radial with respect to the shaft 62 and arm 5% is in turn joined to both clamps t and i3 by links e2 and- 94 respectively.
One end of the links 92 and 8d is pivotally secured as at- S6 to the arm- Si! and the opposite outermost ends of links 52 and 95 are pivotally secured to the corresponding clamps '|6 `and 'i8 as at 98. The marginal edges of the sections t6 and 58 adjacent the slots Eil and 52 are 4preferably reinforced to prevent bending when Yplaced in use and to more rigidly support the clamps lt and 'i8 at` hinges 85".
A horizontallbrace |98 underlying the table top Ui has a pair of depending arms |52 and me, theffor-merpivotallyv receiving as at |05 an elongated-lever |88. A link H0- is pivotally secured 4 to the arm m4 as at H2. Link HD is provided with slots H4 and H6 adjacent each end respectively thereof for receiving pivot pins H8 and |20.
Pin H8 serves to connect lever |08 and link H5, while pin |20 joins arms 33 with link H0. A spring |22 holds the lever |08 biased toward the uppermost end of its path of travel, said spring interconnecting brace and lever |08.
I Assuming the assembly 42 to be in operative position within the arms 68 as illustrated in Figs. l and 2 of the drawings, the operation is as follows:
The strip of linoleurn 4i) is laid upon the section I5 of top ill and threaded below the cutter 28 when the latter is in the raised position shown by full lines in Fig. 3. That end of the linoleum i8 adjacent the assembly ft2 is thereupon laid upon the uppermost clamp 'i6 and extended into underlying relationship with respect to the marginal edge of section 58 adjacent the hinges 86 for clamp l5. The operator thereupon grasps the crank @ai and rotates shaft 62 relative to drum :it to move the clamp 'i5 outwardly and to thereby grip or pinch the end of linoleum strip di) in place between a portion of the uppermost arcuate face cf clamp it and the drum section 13S, all as illustrated in Fig. e. Such relative rotation between the shaft 52 and the drum lil will, also, move the clamp 7S inwardly to the full-line position shown in Fig. 4. After the strip liti has been thus secured to the drum 4, continued rotation of the shaft 62 will cause rotation of the entire drum lili, and the strip of material lltwill be pulled along the table top I4 below cutter blade 2e and will be coiled about the drum de.
As soon as the desired amount of linoleum it is coiled upon the assembly 2, the operator steps upon the lever |03 to cause downward movement of end 39 of cutter blade 23. Such action commences the severance of linoleum 50, whereupon the operator grasps handle 34 to swing cutter blade 28 downwardly and to complete the transverse cutting thereof.
Through use of the lever |88 and its associated parts, it is possible to normally dispose the entire blade 23 above table Hi where the linoleum can be easily inserted below cutter blade 23Y for attachment to the assembly d2.
When it is desired to remove the roll of linoleum from the drum 45, the operator merely removes the entire assembly 42 from the support` ing arms 58, rotates the shaft 62l slightly in a counter-clockwise direction with respect to the drum d4, thereby pulling the clamp 'it to a position for releasing the inner end of the linoleum The operator may thereupon grasp crank G4 and draw drum M from the roll.
it is seen that when the assembly i? is used in connection with the supports 53', the direction of rotation of drum lili during the ooiling operation is as indicated by the arrow in Fig. 4. If the operator is in a position where it is morey desirable to utilize the supporting arms GS for receiving assembly 32, then the rotation of the shaft 62 relative to the drum lid and the rotation of drum le itself is anti-clockwise. Whenv so used', clamp 15 is used in lieu of clamp TG', and the operation is identical to that just above enumerated.
It is, also, apparent that the assembly 42 is capable of many changes and modifications. In this respect, the length of the' drum 4t will determineA whether or not the single, elnogated clamps 'I5 and i3 are used or a number of spaced-apart clamps in lieu thereof. The length of the shaft 62 and of the drumv 44 will,. alsoI determine the 'with respect to assembly 42.
number of assemblies 88-90-f-92-9t that are needed. u
It is noted in Fig. 4 that outward movement of the clamp 78, when it is desired to release clamp TG, is limited by the coiled material 28 on assembly d2, and while sufficient space has been provided to permit such removal of the roll, Fig. 5 shows how such problem may even more effectively be met.
A drum 200 is made precisely as above de scribed with respect to drum M. A pair of arcuate, elongated sections 202 and 294 are held apart by partitions, one being shown in Fig. 5 and designated as 296. These partitions are provided with notches 208 and 210, registering with slots 212 and 2M respectively of drum 299.
Partitions 296 rotatably receive a shaft 215, having a crank on one end thereof (not shown) and one or more pairs of clamps 218 and 222 are hingedly joined to the section 294.
A bracket 222 has a short link 224 pivoted thereto and pivotally receiving the proximal ends of links 22E and 228. The opposite ends of links 225 and 228 are pivotally joined to clamps 218 and 220 respectively.
It is seen that the clamping action of members 2|8 and 220i is the same as above described However, when shaft 216 is rotated with respect to drum d in one direction to move link 224 from the full line position to the dotted line position shown in Fig. 6, both clamps 218 and 229 will move outwardly though but one of the clamps is actually used to hold the sheet material. Shaft 218 may then be rotated in either direction to withdraw clamps 2I8 and 220.
The inoperative clamp will prevent tight rolling of the material on the drum 205 and when the clamps are simultaneously released, drum 294 can easily be withdrawn from the coiled material.
Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:
1. A linoleum rolling assembly comprising an elongated drum having a slot therein; an elongated, rotatable shaft on the longitudinal axis of the drum and secured thereto for rotation with respect to the drum; a clamp normally disposed in the drum, said drum having a marginal edge adjacent the slot thereof partially overlapping the clamp, said clamp being secured to the drum therewithin adjacent said marginal edge for swinging movement toward and away from said shaft, said clamp being disposed for movement through said slot beyond the outermost surface of the drum when the clamp is swung away from the shaft toward the outermost end of its path of travel toward said marginal edge; and means interconnecting the clamp and the shaft for swinging the clamp toward said outermost end of its path of 'travel when the shaft is rotated in one direction relative to the drum, whereby to grip one end cf said linoleum between the clamp and said marginal edge during rolling and to render the roll of linoleum readily removable from the drum upon swinging of the te ward said shaft.
2. A linoleum rolling assembly comprising an elongated drum having a slot therein; an elongated, rotatable shaft on the longitudinal axis of the drum and secured thereto for rotation with respect to the drum; an elongated clamp normally disposed in the drum, said drum having a marginal edge adjacent the slot thereof partially7 overlapping the clamp; a hinge along one longitudinal edge of the clamp, securing the clamp to the innermost face of the drum adjacent said marginal edge for swinging movement toward and away from said shaft, said clamp being disposed for movement through said slot beyond the outermost surface of the drum when the clamp is swung away from the shaft toward the outermost end of its path of travel toward said marginal edge; a link pivotally secured to the clamp adjacent the opposite longitudinal edge thereof; and means pivotally coupling the link with said shaft for swinging the clamp toward said outermost end of its path of travel when the shaft is rotated in one direction relative to the drum, whereby to grip one end of said linoleum between the clampy and said marginal edge during rolling and to render the roll of linoleum readily removable from the drum upon swinging of the clamp toward said shaft.
