MITER BOX FOR CORNER BEADS AND THE LIKE.
Application filed April 9, 1928.
This invention relates to miter boxes for corner beads and the like.
Objects of this invention are to provide a novel form of miter box which is particularly adapted for. cutting mitered ends in corner beads, coping, or other metal strips folded, shaped, or formed from sheet metal.
It is a diflicult thing to out by hand the desired angle for theends oi these beads, as has been found by those skilled in this line of work, and theresult has been a rather ragged joint between these beads, as a general rule, or else a conside able loss of time in, the fitting operations.
This invention is designed to overcome the defects noted above and objects oil? such invention are to provide a novel form of miter box which is particularly adapted for cutting the corner beads and which is so constructed that it will hold the corner beads in a tilted or angular position while the miter is being cut, and a further object of this invention is to provide a novel form of clamp for rigidly holding the beads in position during the cutting operation.
In view of the fact that it is desirable to carry these devices in the suitcases or other cases carried by the plasterers and slim ilar workers, it is apparent that it is dosh able to form the miter box of very light material, and this invention has, therefore, for a :liurther object, the provision oil? a miter box which is formed of very light material, although equipped with means for preventing the metal saw from cutting the side walls of the miter boX.
Further objects of this invention are to provide a channel-shaped miter box for corner beads or the like which is provided with adj stable supports mounted. within the channelled body portion, and in which these supports may be moved vertically to ac commodate different shapes or sizes of the corner beads so that exact angular tilting of the corner bead may be readily secured in addition to the plate or means for holding the saw at an angle to the axis of the bead.
An embodiment of the invention shown in the accompanying drawings in which:
Figure 1 shows a plan view of the device with a corner head in place and with one oi. the clamps opened;
Figure 2 is a side elevation of the device;
Figure 3 is a transverse sectional view showing the relative position of the supports and a corner bead.
Serial No. 268,717.
Referring to the drawings, it will be seen that the miter box comprises a body portion oil. channel shape having a bottom 1 and sides 2 and These portions are preferably cast from aluminum or of other light material. Th slots, however, for guiding the saw will soon wear, it formed in this aluminlun or other light material, and consequently, a pair of hardened steel plates 4 are secured by means of screws to opposite sides of the body. portion and approximately centrally thereof, as shown in Figures 1 and 2. These plates are provided with diagonal and transverse slots 5 and 6 adapted to receive the saw and the slots, of course, are also termed in the sides 01? the body portion.
/Vithin the channel-shaped body portion, a pair o'li supports 7 and 8 are positioned. At least one of these supports is adjustable, for instance, the support 8. This is secured by providing wing bolts 9 which are carried by the support 8 and which project through slots 10 :tormed in the side wall. 3. These wing bolts are provided with wing nuts 11. so that the adjustable support 8 may be clamped at any desired vertical position. The other support 7 may or may not be adjust-able. It may be made adjustable in, the manner indicated tor the support 8. llowever, it has been found satisfactory to rigidly secure this support 7 in place by means of screws, as indicated in Figure 8. These supports 7 and 8 are formed. of wood or other similar material so as to prevent injury to the saw and also so as to nmintain the lightness of the device.
A pair of clamps 12 are carried by hinges 13 adjacent one end and have projecting headed ends 14: at the other end. llhese headed portions let are adapted to be engaged by the-looped upper end of springs 15. The springs 15 have their lower ends attached to the body portion, as shown in Figure 3. In this manner, a yielding pressureis imposed upon the corner bead carried within the miter box.
The corner beads are usually provided with a rounded head 16 and with a pair of diverging wings 17. The edge of the head is adapted to rest upon the support 7 and one oil? the wings 17 is adapted to rest upon the support 8. The upper portion of the head is engaged by the curved or cam-shaped face 18 of the clamp 12, shown in Figure 3, and thus the marginal edge of the uppermost wing 17 is forced into contact with the the supports 7 and 8.
inner face of the Wall 3. The other Wing 17 extends downwardly into the space between fere with the operation ofthe yieldingly held clamp 12.
It is also to be noted that inasmuch as the corner beads go onthe corners of the walls with their central planes at an angle to each Wall face, that-it is necessary to hold the corner beads tilted, or in other words, angularly, While the miter is being cut. This is readily secured by this miter box.
Although the invention has been described in considerable detail, such description is intended as illustrative rather than limiting as the invention may bevariously embodied and as the scope of'such invention is to be determined as claimed.
1. A miter box for corner beads and the like, comprising a channel-shaped body portion' having vertical slots in its side walls and adapted toreceive the corner bead, a support for the head of the corner bead, and a support for one of the arms of said corner head, said supports being spaced apart to provide a space for the other arm of the corner bead and clamping means for looking said bead in place.
2. A miter box for corner beads and the like, comprising a channel-shaped body portion having saw receivingand guiding slots in its side walls and adapted to receive a corner head, a air of spaced supports carried within the c iannelled body and in contact with the side walls and adapted to support the corner bead, and fasteners for holding the supports in place, the fasteners for one of said supports being adjustable, whereby the last mentioned support may be adjusted up or down to vary the angular setting of the corner bead and clamping means for locking said bead in place.
3. A miter box for corner beads and the like, comprising a channel-shaped body portion having saw receiving and guiding slots in its side walls, adjustable means located within the channelled body portion upon which a corner bead may rest, and a yielding clamp carried by said body portion for holding the corner head in place upon the support.
4. A miter box for corner beads or the like, comprising a channel-slmped body portion having side walls, said body )ortion being formed of light weight material, a pair of hardened plates secured to the side walls and having saw receiving and guiding slots therein, means carried within the body portion for supporting a corner bead in an angular position, and clamping means for locking said bead in place.
In testimony that I claim the foregoing I have hereunto set my hand at Racine, in thecounty of Racine and State of IVisconsm.
