UNITED] STATES v THOMAS W. MILTON, OF EAST LOUIS, ILLINOIS STACK POLING AND GUY-PAINTING DEVICE.

Application filed January 12, 1925. Serial No. 2,051.

To all 'wlz-omit may concern:

Be it known that I, THOMAS W. -MILTON, a citizen of the United States, residing at East St. Louis, in the county of St. Clair, State of Illinois, have invented certain new and useful Improvements in Stack Poling and Guy-Painting Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in devices used in connection with thepainting of stacks, and the guy wires thereof.

In painting a stack, and especially the ordinary high metal stack, it is necessary to suspend a block and tackle on the upper end of the stack, to which tackle is connect' ed the seat or boatswains. chair for the painter. To suspend the block and tackle it is necessary to engage a hook over the upper edge of the stack, and in the ordinary method now employed, light poles, to which is connected the hook, are pushed up along the side of the stack until the hook is above the stack, when the operator lowers, the poles to permit the hook to engage the edge of the stack. This method requires the services of several men, and approximately an entire day. It is to overcome this difficulty that the present device has been designed. Thedevice has for itsobject to carry a pole, on which is disposed the hook, up a guy wire of the stack until the hook is sulficiently high above the stack to engage thereon when the polefis lowered. ,The pole is carried on a motor propelled carriage, which is driven up the guy wire, said carriage also being provided with means for distributing oil, grease, or paint on the guy wire as said carriage moves upwardly and downwardly on the guy wire.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawings.

In the drawings:

Figure 1 is an elevation of a stack and guy wire, showing the invention in the act of applying the hook.

Figure 2 is an enlarged vertical longitudinal sectional view through the carriage.

Figure 3 is a vertical transverse sectional view through the carriage, on the line 33 of Figure 2.

Figure 4 is an elevation of the stack and invention showing the hook engaged withthe stack. V g F igure 5 is a fragmentary detail of-the upper end of the arm 20, showing the hook 21. 1

Referring particularly to the accompany ing drawing, 10 represents the upper por-'- tion of a stack, and 11 the guy wires thereof.

Arranged to travel up and down on' the guy wire 11 is a carriage 12, which consists of the upper and lower hinged sections 13" and 14,.arranged respectively above "and below the wire, and having therein the wire:

engaging wheels 15 and 16, the latter of which are driven by the electricmotor 17 also mounted in the casing. On the rear" portion of the top section of the casing there is formed a pivot support 18 in which is pivotally mounted the angle-portion of the pole 19, the longer arm 20 ofwhich has means, such as the laterally directedhook 21, for supporting the hook 22, which is to be engaged over the upper edge of the-stack 10, while the shorter arm 23 is provided with a weight 24 which maintains the'pole' in an approximately vertical position, .while the carriage is traveling upwardly on the guy wire, and whereby said pole will be in no danger of striking the stackand dislodging the hook from the pole. On the other side of the pole, at a short distance abovethe weighted arm 23, is a short-arm 25, to which is connected one end ofa cord or wire 26, and which is arrangedtorock. thepole:

upwardly to' position the hook 22 over-the upper edge of the stack, when the cordonwire 26 is pulled. After such disposition of the pole and hook, the carriage is permitted to slide down the guy wire to a sufficient distance to release the hook 21 from the hook 22, and permit the hook to remain suspended or engaged on the stack. Engaged over the lower portion of the hook, which hook is substantially S-shaped, is a cord or cable 27, to one end of which the workman attaches his block and tackle, and

upon pulling on the other end of the cable 27 the block and tackle may be elevated to the upper end of the stack, after which the pulled end of the cable is anchored to some point at the base of the stack. The workman then pulls the boatswains chair up to the desired height. The motor of the carriage receives current from any suitable source, over the conduit 28.

The upper portionof thecarriage carries a receptacle or socket for receivlngja paint or grease container, which discharges its contents on the guy wire, as the carriage is moved upwardly and downwardlythereon.

The socket is shown at 29.

The pintle ends 15 of the wheels 15 are supported in the vertieal slots 81, of the vertical side walls of the upper section of the marriage; Slidably supported on the saidwsiderwalls, imstraddling relation tothe upper wheels 15, are the U-shaped members :or gyokes 533, the, lower ends of thelegs of whichwrest or bear on the; said pintleends of the wheels. Pivotally supported in each endsofgthenpper ;portion of the carriage, and eextending longitudinally toward the @center; thereof, are-the-j-a-rms 34,-the free ends of. which support the cup 36, in which is disposed theilower end of a coil spring 35.

On the upper end ofthe spring is a similar 0111336, on the upper side of which bears thertensiontscrew :37 engaged through the uppernwallwof the carriage, and by means of .which said armsmay be swung clownwardlyito causethe-Wheels l5 tobear firmly on thexiuppersi'de ofithe guy 11, in cooperation :with thedrive wheels 16, therebelow,

to permitmore efficient traction on the guy, and theIcfiective-movement of the carriage upwardly on ,the guy. By means of this arrangementit is possible to use the carrrageonguys of different diameters.

:Theipivotalrportion'of the pole 19 is arrangedflto engage with :a stop lug 30, on; the carriage, to :prevent the pole from sw nging outwardly beyond a vertical position,

under the-influence of the weighted ,arm 23,

thereby: preventing engagement of the hook with ithe: side ofrthe stack and possible dislodgement of the hook from. the pole, while the carriage .andpole are. moving upwardly. NV-hile 11 have shown and described the carriage as'being drivenxalong a guy wire by meanstofuan;electric.motor, I wish it understood :that, in :the event electric .cur-

rent is not available, any suitable and well known means may be used for propelling the carriage.

What isclaimed is: '1; A device for placing'a suspending hook onthe upper end a ofia stack to be painted comprising a carriage arranged to be driven upa guy wire of ay-stack, a pole on the carriage arranged to supporta hook, and means for moving the pole into such position with relation to the stack that the hook'will be engaged with the stack 'whengthe carriage and pole are withdrawn therefrom.

2. Adevice for placing a painters hook; on 1 a stack compris ng a motor drlven car riage arranged to move upwardly wanddownwardly on a guy wire of a stack, a pole pivotally mounted on the carriage it and having gravity means for maintaining the pole in upright position, means on the pole for supporting ahook inpositiontobe engaged on a stack, and means for moving the pole againsti-the force of the gravity means for placing the hook on the stack. a

3. A device for placing a suspending hook on the upper end of a stack comprising a track extending fromthe ground to a point adjacent the top of thestacln a self-propelled vehicle arranged to run onthe track,

urgingsaidzfriction means into engagement with'the guy, and a :tensioning means engaged with the arms for :movingathe ilatter.

In testimony whereof, I aflix my signature. a V
