2 Claims.

This invention relates to improvements in machines for rolling rugs and applying thereto a wrapper for the purpose of protecting them while they are in storage or while being handled or shipped.

A further object is to provide an improved machine of this character by means of which the rug may be wrapped or rolled about stick or core, which latter is allowed to remain Within the rug to prevent the rug from bending or crumpling.

A further object is to provide an improved machine of this character in which the rug as it is rolled is supported by positively driven rollers, and a positively driven floating roller engages and rests upon the top of the roll and cooperates with the supporting rollers to cause the rug to be rotated and compactly rolled.

A further object is to provide improved means for counterbalancing the floating roller, and improved means for raising or lowering the floating roller.

To the attainment of these ends and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty in substantially the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawings illustrating this invention and in which Figure 1 is an elevation taken from one side of a machine of this character constructed in accordance with the principles of this invention.

Figure 2 is an elevation of a portion of the machine taken from the other side thereof.

Figure 3 is a front elevation of Figure 1, with parts broken away.

Figure 4 is a detail vertical sectional view taken on line 4-4, Figure 3, on an enlarged scale and with parts omitted.

Figure 5 is a detail sectional view of some of the parts shown in Figure 4, showing them in different positions.

Figure 6 is a perspective view of a rolled rug having a wrapper applied thereto.

Referring more particularly to the drawings, the numeral 10 designates generally a supporting structure which may be of any desired height and of any desired width, and the supporting structure is provided with spaced uprights 11. Between the uprights 11 are arranged parallel rollers 12-13, which extend substantially across the space between the uprights 11. The roller 12 is journaled at one end as at 14 in a bearing, preferably formed in the upright 11, and at its other end in a removable bearing 15. The roller 13 is preferably journaled at one end in a bearing in one of the uprights 11 and at its other end in a removable bearing 16 to form a support for the shafts of the rollers beyond the frame.

1932, Serial No. 638,732

Arranged adjacent the front of the roller 12 is a table or platform 17 for supporting the rug it is into the machine, and arranged adjacent the rear face of the roller 13 is a support 18 which preferably inclines downwardly and is provided with a stop 19 so that when the rug has been completely rolled, it will pass out of the machine on to the support 18 to be conveyed away from the machine.

Connected to the roller 12 on one end thereof is a sprocket wheel. 20, over which a sprocket chain 21 passes and this sprocket chain also passes over a sprocket wheel 22 secured to the adjacent end of the roller 13. Secured also to the roller 13 is a sprocket wheel 23 which is preferably of a diameter considerably greater than the diameter of the sprocket wheel 22, and the sprocket Wheels 20 and 22 are of such a diameter with respect to each other that the desired speed of rotation of the rollers 12 and 13 will be obtained.

Passing over the sprocket wheel 23 is a sprocket chain 24, which in turn passes over a sprocket wheel 25, to which latter is connected a gear 26 preferably in the form of a worm gear. This worm gear meshes with a worm .27 on a shaft 28 and which shaft is driven by a motor 29, suitably located so that the rollers 12 and 13 will be rotated.

The motor 29 is connected with the shaft 28 in any desired or suitable manner, preferably by means of a belt and a clutch 31 controlled by a hand lever 32 is provided for connecting and disconnecting the motor 29 to and from the shaft 28, so that the operation of the machine may be controlled by the operator standing in front of the platform or support 17.

Pivotally supported by one end, preferably by the shaft of the roller 13, is a link 33, which link may be of any desired length and to the free end of the link is pivotaliy connected as at 34, one end of another link 35. J ournaled in the free end of the link 35 is a shaft 36, one end of which passes through a slot 37 in one of the uprights 11, and the other end of the shaft passes through a similar slot in the other upright 11. Carried by this shaft 36 is a roller 38 which may be of any desired diameter, but is of a length substantially co-extensive with the length of the rollers 12 and 13, and the roller 38 is so positioned that it, will stand above the space between the rollers 12 and 13.

The shaft 36 at one end is journaled in the free .end of the link 35 and connected to the shaft in proximity to the link and for rotation with the shaft is a sprocket wheel 39, over which a sprocket chain 40 passes. This sprocket chain also passes over. another sprocket wheel 41 journaled preferably upon the pivot 34, and to which sprocket wheel 41 a sprocket wheel 42 Hit is connected for rotation therewith. A sprocket chain 43 passes over the sprocket wheel 44 and also over a sprocket wheel 45 secured to the adjacent end of the shaft of the roller 13.

Thus it will be seen that when the motor is operated motion will be imparted to the shaft 28 and from the shaft 28 the sprocket wheel 23 will be rotated. This in turn will rotate the roller 13 and through the medium of the sprocket chain 31 rotate the roller 12. At the same time the sprocket wheel 45 on the other end of the roller 13 will, through the medium of the sprocket chains 43, sprockets 42-41, sprocket chain 40 and sprocket wheel 39, rotate the floating roller 38. The links 33 and 35 being pivotally connected together in the form of a toggle, will permit the roller 38 to rise and fall with respect to therollers l2 and 13 and at the same time will maintain the centers of the sprocket wheels supported by the links, an equal distance apart so as not to interfere with the driving of the respective sprocket wheels.

The floating roller 38 is supported by the carpet 46, as the latter is being rolled and is counter balanced preferably through the medium of a counterbalancing weight 4'7, to which is connected rods 48, and to the ends of these rods is connected one end of sprocket chains 49, each of which passes over a sprocket wheel preferably adjacent the top of the uprights 11 and on the outside thereof, and the free ends of the sprocket chains 49 are secured to collars 51 which encompass the shaft 36 of the roller 38 so as not to interfere with the rotation of the roller.

It will thus be seen that when the floating roller 38 is lowered to contact with the carpet 46 as it is being rolled, and when the diameter of the roll of carpet increases, the roller 38 will be automatically raised, the counter-balancing weight 47 permitting the roller to remain in contact with the carpet roll at all times during the operation of the machine.

Any suitable means may be provided for raising the roller 38 at any time and to that end the sprockets 50 may be connected to a shaft 52 which is journaled preferably in the uprights 11, and extends across a space therebetween. A handle or operating wheel 53 is connected to the shaft 52, and arranged in any convenient position. By the operation of this hand wheel 53, it will be manifest that the roller 37 may be raised or lowered at will.

A platform 54 is provided which is preferably iarranged adjacent the top of the uprights 11,

and supports the wrapping paper 55, preferably in the form of superposed sheets.

A support or table 56 is preferably provided adjacent the support or table 17 and is spaced i therefrom to permit the operator to stand therebetween. Upon this table or support, 56, the carpet or rug is initially and partially rolled about a stick 5'7, as shown in Figure 1. i

It is thought that the operation of the maichine will be clearly understood from the foregoing, but briefly stated it is as follows.

If the rug is of any considerable size, two op-.

erators will be necessary, but if the same is of a smaller size, one operator will be able to manipulate the machine.

The floating roller 38 is first raised by means of the operating handle or wheel 53. The operators then partially roll the rug upon the table 56, either with or without the use of a stick as a core, as shown in Figures 1 and 4. The partially rolled rug is then placed upon the rollers 13 and the floating roller 38 is lowered to contact with the top of the roll. The rug is then rolled to any desired extent, after which a sheet of paper is taken from the supply and one end is inserted in the roll on top of the unrolled portion of the carpet. The rolling operation is then continued (see Figure 5), causing the remaining portion of the carpet or rug to be rolled and at the same time rolling the paper wrapper around the roll, with the forward edge of the Wrapper wound within the lays or wraps of the carpet. The free end of the paper is then sealed in any suitable manner, such as by means of the use of glue. The rollers 12 and 13 are stopped by the manipulation of the control lever 32. The ends of the wrapper which project beyond the ends of the roll are then folded as at 58 and sealing tapes or strips 59 may be fastened over the folded ends of the roll. After the ends of the wrapper have been sealed the operators remove the wrapped rug by pushing or rolling the same off of the rollers 13 and on to the platform or support 18.

While the preferred form of the invention has been herein shown and described, it is to be understood that various changes may be made in the details of construction and in the combination and arrangement of the several parts, within the scope of the claims, without departing from the spirit of this invention.

What is claimed as new is:

1. A carpet rolling machine comprising a frame, a pair of fixed and parallel supporting rollers journaled in the frame, a floating roller arranged above and parallel with the first said rollers and between all of which rollers the carpet is rolled, driving mechanism connected with all of said rollers for positively rotating them, a receiving platform on one side of the rollers for the carpet to be rolled, a delivery platform on the other side of the rollers for the rolled carpet, and a platform above the said rollers for holding a supply of superposed flat wrapping sheets in a convenient position for the operator of the machine and with its delivery end adjacent the operator, the receiving platform projecting for a considerable distance in front of the delivery end of the last said platform.
