Description
Um. 25,, 193%.. M. BRETH CLOTH UNWINDER Filed Oct. 22, 1957 INVENTOR M/lXlM/Z/AW 618E777 BY l j y ATTORNEY Patented Oct. 25, 1938 UNITED STATES PATENT OFFIQE 14 Claims.
This invention relates to cloth unwinders.
An object of this invention is to provide a cloth unwinder in which a roll or bolt of cloth rests on a plurality of parallel rollers during the unwinding operation, thus eliminating necessity for core support.
A further object of this invention is to provide a cloth unwinder of the character described, on which there may be unwound a roll of cloth which is wider than the table on which the unwinder is supported, and in which there is provided adjustable end stops to accommodate rolls or bolts of cloth of various width.
Still another object of this invention is to provide a cloth unwinder of the character described which is collapsible and in which projecting parts may be removed for packing and shipping the machine in compact form.
Another object of this invention is to provide a compact, strong and rugged machine of the character described which shall be relatively inexpensive to manufacture, on which cloth may be very easily unwound, and which shall yet be practical and efiicient to a high degree in use.
Other objects of this invention will in part be obvious and in part hereinafter pointed out.
The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which will be exemplified in the construction hereinafter described, and of which the scope of application will be indicated in the following claims.
In the accompanying drawing, in which is shown one of the various possible illustrative embodiments of this invention,
Fig. 1 is an end view of a cloth unwinder with a roll of cloth thereon in position for unwinding the cloth from the roll;
Fig. 2 is a front elevational view of the structure shown in Fig. 1, with parts in cross section;
Fig. 3 is an enlarged cross-sectional view taken on line 3-3 of Fig. 2;
Fig. 4 is a side elevational view of the screw thread extension bar;
Fig. 5 is an elevational cross-sectional View of an extension bar, illustrating a modified construction, and
Fig. 6 is a cross-sectional view taken on line 6--6 of Fig. 5.
Referring now in detail to the drawing, Ifl designates a cloth unwinder embodying the invention, and l l designates a roll of cloth mounted on said unwinder and showing the cloth l2 from the roll being unwound therefrom. The unwinder it, comprises a pair of similar parallel vertical side frames or stanchions l4.
Each frame M has an upwardly and rearwardly inclined straight portion l5 from which there extends a downwardly and forwardly curved portion l6. Extending from the bottom end of said straight portion I5, is a downwardly and rearwardly inclined leg ll, which may carry a rubber .shoe Hi to contact the top of the table [9.
Extending downwardly from the front end of the curved portion I6 is an ear 2!), and extending from said ear, is a forwardly and upwardly curved portion 2! having substantially the same curvature as said portion I6. Extending from said portion 2i of the frame I4 is a downwardly and forwardly inclined leg 22, carrying a rubber shoe 23, engaging the table IS. The portions 2&1 of the side frames M are interconnected by a horizontal connecting bolt 25. The upper ends of the portions 15 of said side frames are also interconnected by a horizontal rod 26. The upper ends of curved portion 2| are also interconnected by a horizontal rod 21. The frames i l are thus rigidly held together in vertical planes, by the members 25, 26 and 21.
The curved portions 16 and 2! of the frames it are provided with pairs of aligned bosses 23, formed with screw threaded through openings carrying threaded pins 29, having conical inner ends 30. On each pair of pins 29 there is rotatably supported a roller 3|, comprising a sleeve 32 within the outer ends of which are fixed plugs 34, formed with central openings 35, receiving the conical portions of said pins. =1The two rollers 3! are paralled and spaced from one another and are at the same height. The plugs 3 3 are made of metal so that the rollers may easily rotate on the conical ends 30. Lock nuts 37 are provided on said pins to hold the same in adjusted positions.
The roll of cloth II is placed on the roller iii, the cloth I I passing upwardly from said roll over the rod 26. Upon pulling the cloth l2, the roll ll will turn easily on the rolls 3! to permit unwinding of the cloth.
Screwed within the ends of the rod 26 are extension bars 40 to be used when unwinding rolls of greater width than the width of the bar 25.
Adjustable stop means is furthermore provided for the ends of the roll of cloth I I. To this end the ears 20 of the frames M are formed with through openings 42. Slidably mounted within each opening 42 is a horizontal rod 43, formed at its outer end with an upwardly extending portion 44, terminating at the top in a circular portion 46. Slidably mounted on the rod 25 are a pair of circular disks M, each formed with a through opening 48, through which said rod passes. The disks 41 are also formed with through openings 50, parallel to the openings 48, receiving the inher ends 52 of the rods 43. Said ends 52 of the rods 43 may be fixed to said disks ll by tapered cotter pins 53, or in any other suitable manner. The disks 4'! may also be provided with setscrews 55, adapted to engage the rod 25 for holding said disks in'adjusted position on said rod.
By loosening the set-screws 55 the rods 43 may be moved in or out to accommodate rolls or bolts of cloth of various width. The portions 44, 46 of the rods 43 are adapted to act as stop means to prevent side movement of the roll II. It will be noted that with my improved machine rolls of cloth may be unwound which are wider than the table i9. When shipping the machine the rods 43 are pushed inwardly toward each other and the extension rods 40 may be unscrewed. The unwinder may thus be shipped or stored in compact form.
As illustrated in Figs. 5 and 6 of the drawing, the rod 26 may be replaced by a tubular rod 26a and the extension bars 40 may be replaced by tubular bars 48a, telescoping within tube 26a. ihe tube 26a may be formed with elongated slots 60 and telescoping tubes 48a, provided with lugs- Gl, disposed within the slots and adapted to engage the portions [5 of the frame to limit outward movement of said telescope tube. For the purpose of packing or shipping, the tube 48a need merely be pushed inwardly within the tube 26a. so as not to project therefrom. It will be noted that with my improved unwinding machine, no centering cores are necessary to support the roll or bolt of cloth.
While the drawing illustrates the unwinding device used for unwinding cloth from a roll of cloth, it will be understood that other bolts of cloth may be unwound on said device, for example, bolts in which the cloth is rolled on flat boards.
It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.
As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiments above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
Having thus described my invention, I claim as new and desire to secure by Letters Patent:
