Specification of Letters Patent Patented Dec. 13, 1921.

Application filed November 16, 1918. Serial No. 262,915.

T 0 all whom it may concern:

Be it known that I, LOUIS T. FREDERICK, a citizen of the United States, and a resident of Wilkinsburg, in the county of Allegheny and State of Pennsylvania, have invented anew and useful Improvement in Heat-Regulating Attachments for Tube- Machines, of which the following is a specification.

My invention relates to heat-regulating devices for tube machines, and it has for its primary object the regulation of the amount of heat transmitted to sheet material which has previously been treated with an adhesive and is to be automatically wound upon mandrels to form tubes.

Heretofore, it has been customary, in heating. treated material which is being wound to form tubes, to employ a heating device in which heat regulation has been accomplished by varying the amount of heat delivered to the heating device, and, subsequently, transmitted to the treated material. This method, however, is subject to criticism on account of its inability to provide quick regulation and because of the constant attention required by it throughout the operation. In view of this, one object of my invention is to provide a heat-regulating device, for tube machines, which shall respond quickly to regulation and, therefore, require less attention while in operation.

A further object of my invention is the provision of a heat-regulating attachment, for tube machines and the like, which shall so efliciently cooperate with the machine to which it is attached that a more uniform and better product 'shall result.

A still further object of my invention is the provision of heat-regulating devices, for

tube machines, of great durablity and of such construction that all parts shall be easily accessible for repair work.

WVith these and other objects in view, my invention will be more fully described, illustrated in the drawings, in which corresponding numerals indicate like parts, and then particularly pointed out in the appended claims.

In the drawings Figure 1 is an end view of a tube machine having a heat-regulating device attached thereto that embodies my invention; Fig. 2 is a side view of the machine and the heat-regulating device shown in Fig. 1, and Fig. 3 is a longitudinal sectional view of the heating roll showing an electrical heating coil disposed therein.

A tube machine, of the well known Haefely type, has been employed to illustrate, in the drawings, the character and mode of operation of my improved heatregulating device and, on account ofthe well known construction of such machines, only-a brief description will be given herein.

In Figs. 1 and 2 is shown a tube machine 1 to which my improved heat-regulating device may be adapted. The tube machine 1 here shown, has a frame 28 the inner faces of which are provided with channels 29 to receive, and permit movement of, portions of a frame 30, which support a pressure roll 31. The frame 30 and the pressure roll 31 may be raised and lowered by any suitable means (not shown), and the right degree of pressure to be exerted may be delicately governed by adjusting a hand wheel 33. A roll 34, which may be driven by any suitable means, not shown, is journaled in brackets with which the frame 28 is provided and serves, with the aid of a heating roll 35, to support a mandrel 36. The heating roll 35' is mounted upon' brackets 37 pivotally fastened to the frame 28, the brackets 37 being provided with gear-segments 38. Pinions 39 are suitably disposed to mesh with the gear-segments 38, and gear wheels 40, which have a rigid and concentric relation to the pinions 39, mesh with gear wheels 41 mounted upon a shaft 42 having a hand wheel A3. A pawl 44 engages one of the gear wheels 11 to hold theparts' in their adjusted positions.

The operation and adjustment of the heating device, embodied in the machine shown in Figs. 1 and 2, involves the hand wheel 43 being so operated as to actuate the gear wheels 11 to impart movement to the pinions 39 through engagement with the gear wheels 40. The pinions 39,meshing with the gear: segments 38, tend to raise or lower the brackets 37 and the heating roll carried by them. according to the direction in which the hand wheel 42 may be turned. The heating roll 35 transmits a quantity of heat to treated material passed over it in accordance with the degree of engagement of the roll with the material. The roll 35 may be heated by any suitable means, such as an electrical coil 32, shown in Fig. 3. The heat imparted to the treated material may be controlled gear segments, pinions material passing over it engages it to a v the appended claims.

I cla1m as my invention? 1. In a heat-regulating device for tube machines andthe like a heating roll and ad justable su ports therefor.

. 2. In a eat-regulating device for tube machines and the like a heating roll, adjustable supports therefor and. means for ad'- justingsaid supports.

3. In a heat-regulating device for tube machines and the like, a heating roll and means for adjusting the position of the heat-' ing roll to vary the extent of its engagement with treated material passed over. it.

4. In a heat-regulating device for tube machines and the like, a heating roll, adjustable supports therefor provided with disposed in engagement with the gear'segments and means for rotating the pinions.

v5. In a heat-regulating device for tube machines and the like, a heating roll, adjustable supports therefor provided with gear segments, pinions disposed in engagement with the gear segments, means for rotatingthe pinions and means for maintaining. the pinions in-any adjusted position.

6. In a heat-regulating device for tube machines and the like, a plurality of movable brackets provided with gear segments, a heating roll supported by the brackets, a

plurality of pinlons adapted to engage the' gear segments, means for actuating the pin- 1ons and means for maintaining the pinions in any adjusted position.

.7. n a heat-regulating device for tube machines and the like, a plurality of movable brackets provided with gear segments, a heating roll supported by the brackets, a plurality of pinions adapted to engage the .gear segments, manually operable means for actuating the pinions and means for maintaining the pinions in any adjusted position.

In testimony whereof, I have hereunto subscribed my name this 26th day of Oct.,

' LOUIS T. FREDERICK.
