PATENT 'OF UNITED STATES TOI-IN BERNARD DOERR,
OF ORLANDO, FLORIDA.
WIRE STRETCHER.
Application filed September 1, 1925.
T all whom it may concern.:
Be it known that I, JOHN BERNARD Donau, la citizen of the United States, and a. resident of Orlando, in the lcounty of Orange and State of Florida, have invented certain new and useful Improvements inVVire Stretchers, of which the following is a specification.
This invention relates to wire stretching machines and has for its object the provision of a device for pulling wire screening taut when applying the wire to such frames as are used for windows and doors.
A further object of the invention is the provision of a device for stretching wire screening when being applied to frames and in which a pair of rollers are employed, one being adjustable relative `to the other and mounted for positive rotation, said rollers being adapted to be locked against movement when the wire has been stretched to a predetermined degree.
This invention will be -best understood from a consideration of the following detailed description, in view of the accompany ing drawings forming a part of the specification; nevertheless it .i-s tovbe understood that the invention is not confined to the disclosure, being susceptible of such changes and modifications which shall define no material departure from the salient features of the invention as expressed in the appended claims.
In the drawings:
Figure 1 is a view in perspective of a wire screen stretching device.
Figure 2 is a vertical longitudinal sectional view of the device shown in Figure 1.
Referring more particularly to the drawings, a frame is provided in which designates a pair of standards made of metal and a pair of inturned ears 11 to receive the ends of a head block 12. These ends are secured to the ears in any approved manner as by screws or bolts. Each of the lower ends of the standards are provided with inturned flanges 13 which are secured to the under face at the ends of a base 14.
Angle iron guides 15 are secured to the base 14 and are spaced from the standards to receive alined pairs of bearing blocks 16 and 17. The adjacent ends of the blocks are provided with lugs 18 to receive the opposite ends of springs 19 which tend to maintain the block separated and also a pair of rollers 20 and 21. Rigid with the upper end of each bearing block 17 v,is ,an operating rod Serial No. 53,941.
22 which is inserted through a passage 23 in the ends of the head block and terminates at a point above the block. The passages are of slightly larger diameter than the rods to permit ofa slight play of said rods laterally therein.
A pair of inverted U-shaped brackets 24 are secured to the upper face of the head block and in which are pivoted levers 25. The outer ends of the levers are pivotally connected to the projecting ends 26 of the rods 22. The inner ends of the levers have elongated slots 27 which receive a pin 28 carried by the inner end of an operating lever 29. This lever has a curved portion 30 located in a guide 31 and normally resting on a base 32 of the guide which acts as a fulcrum for the actuation of the lever 29 when the outer free end, 33-y is depressed. The free end 33 of said lever is adapted tov be held in depressed position by a catch 34 secured to the head block 12.
A pawl 40 is pivoted on a standard 10 adjacent the ratchet wheel 38 and engages said wheel to lock the shaft 36 and roller 21 against rotation when the wire screen has been suiliciently stretched. The rollers are covered with any suitable material to provide sufficient friction to insure stretching of the wire. i
The operation of my device is as follows:
The lever 29 is released from the catch 34 and the free end raised whereby the lever 25 will be rocked so that the outer ends of levers 25 will be elevated and raise rods 22 when roller 21 will be displaced relatively to end .of thcf'trame and the endet-theA ra'me'is blocked against movement 0n a workbench. After the wire hasy been stretched said wire is nailed to the endo-t' the 'trameadjacerit the stretching device.
lVhat I claim is:
l. A wire screen stretchingdevice coinprising a trame, a roller mounted for rotation in the frame, a second roller mounted for rotation inthe trame, movable bearings tor the second roller, Ameans -tor positively rotatingl the s econdjroller, an'dmmeans for adjusting the bearingstormoving the sec ond roller towards or away from the irst roller, saidadjustifng means consisting of 'rods connected tothe bearings, pivotally mounted levers, lever being connected vto an end ot a rod, andnieans oscillating the levers whereby thel rods are oscillated.
2. A wire screen stretching 'device comprising 'a trame, a rollermo'ungted `tor rotation inthe trame, a second-roller mounted for rotation in theA t'rame,1novable bearings for the second roller, means for positively rotating 'the second roller, and means for adjusting thebeafrings for movin-g the tsecond roller towards or away from the first roller, said adjusting means consisting of rods connected to the bearings, pivotally mounted levers, a lever bei-ng'connected to an endvota rod, the other ends of the levers lbeing fp'rovided "with Aelongated slots, a pin ins'ertedthrougli the slots, and-an actuating lever -pivo-ted on th'e pin and havinga fulcrumon the frame. A
3. .A wire screen stretch-ing device comprising a frame, `a 'rol/ler mounted Jfor'rotation in the frame, a second-:roller 'mounted for rotation in the tra-me, movable bearings lforwthe second roller, means for positively frtatingthe E'se'cbnd roller, and means for adjustingthe bearings for moving the second 'roller towards or away trom the first roller, said adjustingmeans consisting ol rods connected to Athe bearings, pivotally mounted levers, a lever being connected to an end ot a rod, the other endsot the levers being providedwith elongated slots, a pin inserted through the slots, an actuating lever pivoted on the pin and having a bent portion, a guide on Ithe trame to receive the bent portion andcooperating with the bent portion toliprovidea fulcrunrfor the actuating lever.
ll. A wire screen stretching device comprising a trame, aroller mounted for rotation inthe frame, a second roller mounted for rotationjin the frame, movable bearings tor the second roller, means for positively rotating'tlie second roller, and means Iior 'adjusting the bearings for moving the fsecond roller towards or away fromthe 'irst roller, said adjusting means consisting Aof rodsv connected to the bearings, lpivotally mountedl levers, a lever ybeing connected to anend of a rod, the other, ends of ythe levers being provided with elongated slots, a pin inserted through the'slots, an actuating lever pivoted on the pin and having a l'ulcrum on the ftrame, and a catch on the Vtrame adapted to engagey thefree end ofthe 'actuating lever and Vretain the lever infp'osition when maintaining tlre rollers inoperative position.
