MANGLE-APRON GUIDE.

Specification of Letters Patent.

Patented July 21, 1908.

Application filed August 28, 1907. Serial No. 390,437.

T 0 all whom it may concern:

Be it known that I, ELDIE P. Wool), a citizen of the United States, residing at Los Angeles, county of Los Angeles, and State of California, have invented a new and useful Improvement in Mangle-Apron Guides, of which the following is a specification.

My invention relates to an apron guide adapted for use on a laundry mangle provided with an apron adjusting roller and the object thereof is to provide an automatic device which will keep the apron in the center of the cylinders without any attention on the part of the operators using the mangle.

A further object is to provide a' device which in no way interferes with the usual operation of the mangle and which does not injure the apron by its action thereon.

A further object is to provide a device in sim le and economical form so that it is not liab e to become disordered and fail to perform its duty.

I accomplish these objects by means of the device described herein and illustrated in the accompanying drawings in which Figure 1,is a sectional elevation of a mangle to which my guide may be attached. Fig. 2,is a detailed perspective view of parts of the mangle with my automatic guide operatively mounted thereon. Fig. 3,is an enlarged sectional view of the friction reel mounted on the cylinder shaft. Fig. 4,is a viefv similar to Fig. 3 of a modified form of ree In the drawings 5 designates a laundry mangle of approved construction provided with cylinders 6 and aprons 7, the passage of which through the machine is shown in dotted lines. One of the aprons 7 passes over cylinder 8 at the discharge end of the mangle and the other passes over a similar cylinder 9. The apron which passes over cylinder 8 is adjusted and guided by means of a movable cylinder 10 which in usual practice is adjusted by means of a foot lever, (not shown). The apron which passes over cylinder 9 is similarly adjusted by a cylinder 11 over which it passes. As both of these adjusting cylinders are operated in precisely the same manner an illustration and description of one of the same will suffice for both.

In Fig. 2 cylinders 8 and 10 are illustrated with their operating parts and the same will be described, the illustration and description for cylinders 9 and 11 being exactly similar with the exception that they are further re- 4 be operated by a pivoted lever 16.

moved from each other. Adjusting cylinder 10 is mounted in bearings 12 which are mounted on pivoted arms 13 which pivoted arms are movable by means of levers 14. Levers 14 are pivotally connected between their outer ends by a shift bar 15 adapted to Whenever shift bar 15 is moved longitudinally it will be manifest that the ends of cylinder 10 will be moved transversely and in opposite directions. Thus if shift bar 15 is moved to the right in the drawing the right hand end of cylinder 10 will be moved forwardly while the left hand end will be moved rearwardly. From Figs. 1 and 2 it will be noted that apron 7 makes a considerable angle in passing over cylinder 10 so that if one end of cylinder 10 is moved forwardly apron 7 will tend to run squarely off of the cylinder and will consequently slowly run over to the other side of cylinder 8. My device is designed to keep the apron in a central position on the cylinder by automatically moving the adjusting cylinder to run the apron to the side from which it has first moved. In accomplishing this end I place on each end of shaft 17, on which cylinder 8 is mounted, and adjacent the ends of cylinder 8, a friction reel 18 which may be preferably constructed in either of two forms which are shown in Figs. 3 and 4.

In the form shown in Fig. 3 a sleeve 20 is loosely mounted on shaft 17 and carries on its outer end a spool 21 on which chain 22 is adapted to be wound. On its inner end sleeve 20 is provided with a cone pulley 23 whose inner face is placed close against the end of cylinder 8. Pulley 23 is provided with an internal conical friction clutch 24 against which the pulley is pressed by coiled spring 25 whose pressure is rendered adjustable by means of nut 26 in screw threaded engagement with sleeve 20. When apron 7 runs over to one side of the machine and its edge runs onto pulley 23 chain 22 is wound up on spool 21 and the outer end of lever 16, to which the chains are attached, is pulled toward the side to which the apron has run. This action results in moving forwardly the end of the adjusting roller on that side to which the apron has run so that the apron will run over to the other side of the machine. If the apron should run on pulley 23 longer than is necessary to move cylinder 10 to the fullest extent pulley 23 will slide on friction clutch 24 until the apron again moves to the other side of the cylinder.

In'Fig. 4 I have shown a modified form in which pulley 23 is directly secured to sleeve.

' friction clutch form gives better results in use with a new apron where the edges are very tight against the cylinders. Both ul leys are made slightly cone shaped so t at the edge of the apron will run up onto the same easily.

From the foregoing descri tion it will be observed that my device wil guide a mangle apron in a central position upon the cylin ders of the mangle, keeping the same automatically in that position without any attention on the part of the operators using the machine. justing rollers are not moved to their limiting positions as the aprons move from one side to the other very slowly and a very slight movement of the adjusting rollers suffioes to keep the same in a central position.

Having described my invention what I claim as new and desire to secure by Letters Patent is 1. An apron guide adapted to operate with a mangle aving an apron adjusting cylinder, comprising a conical pulley mounted on each end of a cylinder over which the apron passes, each of said pulleys adapted to receive the apron on its periphery, and said pulleys being operatively connected to the adjusting cylinder.

2. In an apron guide adapted to operate In practical operation the ad in connection with a mangle having an apron adjusting roller thereon, a pulley loosely mounted on each end of the mangle cylinder over which said apron passes, said pulleys being of approximately the same diameter as the cylinder and operatively connected to said adjusting-cylinder.

3. An a ron guide adapted to operate with a mangle having an apron adjusting cylinder, comprising a conical pulley loosely mounted on a cylinder shaft at each end of a cylinder over which the apron passes, said pulleys being of approximately the same diameter as the cylinder and being operatively connected to said adjusting roller.

4. In an apron guide adapted to operate on a mangle having an apron adjusting cylinder thereon, a spool loosely mounted on a cylinder shaft of the mangle over which cylinder the apron passes, a pulley frictionally connected with each of said spools, said pulleys adapted to be rotated by said apron, and connective means between said spools and said adjusting cylinder whereby upon the rotation of one of said spools the axis of the I adjusting cylinder is moved.

5. In a device of the class described, a revoluble cylinder, an apron adjusting roller, an

apron passing over said cylinder and said roller, a pulley of approximately the same diameter as said cylinder rotatively mounted on each end of said cylinder, and connecting means between said pulleys and said adjusting roller.

In witness that I claim the foregoing I have hereunto subscribed my name this 21 day of August, 1907.
