Feb. 12, 1935. J. B. M CORKLE FORMING TOOL FOR METAL TAPE Filed July 29, 1952 INVENTOR Jame-.5 5. Mc foe/0.5
ATTORNEY Patented Feb, 12 I935 UNITED "STATES PATENT#OfFFlCE1.; Y 1,991,328," l r FORMING TOQIIFOR METAL James B. McCorkle, Atlanta, a., assignor to United, States. Gypsum Company, Chicago, Ill.,, a corporation of lllinois I Applicationzjuly 29, 1932, Serial 626,081" 10 Claims, (01. 153-1 1 This invention relates to forming tools, and has reference more particularly to tools of the class described for forming-fiat metal foil into angular shapesfor use in reinforcing the. corners ofrooms 5 to prevent cracking'of plasticpaint.
In the construction of the walls of buildings in which plaster board or fiber board is 'used as' a base for plastic paint, it is the preferred practice to apply over the joints between adjoining boards,
a perforated metal foil which is adhesively at:
tached to theboard joint bymeansfof a cementitious joint plaster. Thesort of construction-to which reference is made is particularly described inthe patent to'E. Green No. 1,703,667, entitled Wall board joint system, granted February 26,-
1929. In the corners of the-room,'it is necessary to form the metal foil tape into angular form with the wings of the angle lying in a plane without waves or corrugations; It isa difiicult operation .to accomplish this forming ofthe metaltape by-hand and secure the best resultswith a minimum of labor. v
An object of" this invention, therefore, is to provide a forming tool for metal tape, which will quickly and easily form the metal tape into angular cross-section form.
Another object of the invention is to provide a forming tool for'metal tape, which will be economicalto construct and which may be used from a "day to day without appreciable wear or loss of parts; also to improve formingtools in other respects hereinafter-specified and claimed.
' Reference is to be had to the accompanying drawing forming a part of this specification, in which Fig. 1 is a side elevation of the forming tool,
Fig. 2 is an end elevation of the forming tool,
Fig. 3 is another end elevation of the forming tool,
Fig. 4 is a plan view of the forming tool,
Fig. 5 is a sectional elevation through the forming tool with a roll of metal tape removed, taken on line 5-5 of Fig. 2,
Fig. 6 is a face view of a portion of fiat metal perforated tape, and
Fig. '7 is a perspective view of a section of tape formed into angular cross-sectional shape.
A resilient roll carrier 15 is provided Witha pair of spaced resilient arms 16 which are connected at one end by a web 17. The outer ends of the arms 16 are provided with catches 1 8 which serve to engage the outer endof the hub 13 and preventaxial-movement of the roll 12 during the.
unwinding of the tape 10. The web 1''? is secured,
as by spot welding, tothe web of a channel 19, the outer ends of said channel having trans versely extending flanges 20 which extend throughslots formed in upstanding arms'21 and 22 of a.
supporting frame, the lower ends of said arms being connect'edb'y-a base'member 23. The base 23 has an outstanding section 24 which is engaged by the foot of the workman so asto' hold the forming tool in position floor while in Operation; A
The upper end of theleg '22 is provided with an outstanding flange 26 upon which is mounted an angularly shaped die 27 provided with-a doglegged, angular forming slot-'28 through which the tape 10 is causd to'pa'ss. The die -27 has outstanding base flanges 30 which are secured to the frame flange 26 by. rivets or bolts 31.
I to approach the die 27 perpendicularly regardless of the diameter of the roll 12. "As 'thegtape 10 passes through thedie 27, a longitudinal 901fold is formedin'the tape so thatthe tape will fit a board joint at the corner of the room by a suit- I ableadhesive compositionandthe tape is-torn the corner of i a room. The-tape is applied to the off at the upper-edge of the forming die 2'7. The
top of the die 27 is preferably slightly less than 8" from the floor which is the customary height of a standard base board, thus insuring that the torn bottom end of the tape 10 will substantially register with the top of the baseboard. An aperture 21a is formed in the frame leg 21 to form a handle to be grasped by the workman in carrying the tool from place to place. a
I would state in conclusion that while the illustrated example constitutes a practical embodiment of my invention, 1 do not wish to limit myself precisely to these details, since manifestly, the same may be considerably varied without departing from the spirit of the invention as defined in the appended claims;
Having thus described my invention, I claim as new and desire to secure by Letters Patent:-
