R. MONSCH HAND MITER Filed June 15, 1946 Patented Mar. 22, 1949 UNITED STATES PATENT OFFICE 4 Claims.
This invention relates to a hand miter or a device wherein a shears may be employed to cut a length of material accurately on a predetermined angle with relation to its length.
An object of the invention is to provide a device that can be utilized advantageously to quickly cut material such as for example picture frame moldings so that miter joints at the corners of the frame may be easily and neatly formed.
More specically, an object of the invention is to provide a device in the form of a hand shears in which there is a relatively sharp blade movable into direct opposition to a relatively broad fiat faced dull blade, the dull blade being equipped with a platform arranged at right angles to the plane of the sharp blade and disposed on opposite sides thereof and having adjustable guide plates suitably indexed so that the material to be cut may be positioned on the platform against one or both of the guide plates and cut accurately at a predetermined angle to its length.
Another object of the invention is to provide a mitering guide means that may be readily applied to a conventional type of hand shears to convert it into a hand miter.
With the foregoing and other objects in view, which will be made manifest in the following detailed description and specifically pointed out in the appended claims, reference is had to the accompanying drawings for an illustrative embodiment of the invention, wherein:
Figure 1 is a partial view in side elevation of the improved hand miter;
Fig. 2 is a horizontal section taken substantially upon the line l2 2 upon Fig. 1; and
Fig. 3 is a view in front elevation of the hand miter and may be regarded as taken in the direction of the arrow 3 upon Fig. 1.
Referring to the accompanying drawings wherein similar reference characters designate similar parts throughout, the improved hand miter is preferably made from a conventional type of hand shears consisting of a relatively sharp and comparatively thin blade I movable in opposition to a relatively thick dull blade II having a substantially flat surface I2 opposed to the cutting edge of the blade I0. These blades are equipped with handles I3 and I4 by which they may be operated and are pivotally connected together such as by a rivet or bolt I5.
The above-described shears is a conventional construction readily obtainable upon the open market. The device utilized to convert the shears of a hand miter consists of a section of sheet metal I6 forming a platform extending transversely across the top of the face I2 of the blade Il. At the forward end of this section a pair of ears Il and I8 are bent downwardly so as to embrace the sides of the dull blade Il. These ears have apertures therein and a single hole is drilled through the blade II to accommodate a bolt I9 that is extended through the ears and through the drilled hole to thus attach the platform to the lower blade. The platform provided by the section I6 is preferably longitudinally grooved with a central shallow groove 20 adapted to slightly receive the cutting edge of the blade I0 so that when a section of material M is placed on the platform the sharp blade IU will completely cut through it and pass slightly through the groove. At equi-distant points from this groove upstanding pintles 2| and 22 are secured to the platforms which serve to hingedly mount guide plates 23 and 24 so that they may swing over the platform. Adjacent the marginal edges of the platform there may be holes 25 or recesses adapted to receive the lower ends of indexing pins 26 that are vertically slidable in knuckles 2l on the outer ends of the guide plates. The holes 25 are preferably so arranged that when the indexing pins are therein the guide plates will assume positions that are either to the groove 20 as in the case of the guide plate 23 as illustrated on Fig. 2, or at 120 to the groove as in the case of the guide plate 24 as illustrated in Fig. 2 or if the indexing pin is positioned in the third hole '25 the guide plates may assume positions at 135 from the groove 20.
If it is desired to cut the end of a stick of material M at 90 to its length either or both of the guide plates may be positioned in positions 90 to the groove. The shears is then manually operated causing the sharp blade I0 to cut therethrough. On the other hand if it is desired to cut the end of the material at to its length one of the guide plates such as the guide plate 24 is positioned as shown and the shears operated. If it is desired to cut the material with its end at 45 to its length the guide plate is positioned so that its indexing pin 26 is in the third or last hole and the shears operated While the material is pressed against the platform and against the guide plate as thus positioned, By having two opposed guide plates each of which is swingable about its pintle material such as picture frame molding can be easily and quickly cut with opposed angles of adjacent sections that can be properly assembled to form a neat corner.
From the above-described construction it will be appreciated that the improved hand miter is of relatively simple and highly durable construction and that the shears employed may conform to a conventional shears readily obtainable on the open market.
Various changes may be made in the details of construction without departing from the spirit and scope of the invention as dened by the appended claims.
