FASTENER Theodore Packard, East Orange, N Jt, assignor to B. Packard Co., Inc., New York, N. Y., a corporation of New York Original application March 10, 1952, Serial No. 275,830,
now 'Patent No. 2,715,71i0, dated August 2;, 1 955,. Divided and this application June 13, 1955 Serial No. 514,857: Y
1 Claim. (Cl. 85-13) This invention relates to wood fasteners and is a division of my copending patent application Ser. No. 275,830, now U. 5 Patent No. 2,715,730.
In U. S. Patent No. 2,596,181 there is described and illustrated a wood fastener for fastening a wooden miterjoint, the fastener being characterized in that some of the teeth are so arranged that as the fastener is forced into the wood the two portions of the wood to be joined are drawn together. Subsequently it was found that by a further alteration of some of the teeth .a fastener of substantially improved characteristics could be made and of a type readily adapted for counte-rsinking by various forms of a. simple and especially designed tool. Y
It is an object of the instant invention to provide a fastener that will more thoroughly draw the parts of a miter-joint together than heretofore possible.
An additional object is to provide a fastener that will become locked in the wood while drawing the parts of the miter-joint together.
It is also an object of the instant invention to provide a fastener that will substantially reduce crushing and splitting of the wood as compared with known similar devices.
A further object is to provide tools that will both guide the fastener during insertion and countersink the fastener after insertion so that the fastener will not bend during insertion and by countersinking will permit the wood to be finished.
Still other objects of the instant invention will become apparent in the course of the following specification.
In the attainment of the aforesaid objectives, the improved wood fastener is constituted of a substantially fiat body divided by the vertical center line into two similar portions forming a right angle with each other. Each similar side of the fastener adjacent the free end is turned laterally inwardly at a right angle to the side.- Along the bottom edge of each side of the fastener and adjacent the vertical center line is one-half of a central tooth, each half of the central tooth being bent outwardly to more thoroughly draw the portions of a miter-joint together as the fastener is inserted. At the free end of each side of the fastener is an end tooth, a portion of which is turned laterally inwardly at a right angle to the side to form a virtual anchor across the grain and to further minimize splitting and crushing of the Wood. The angular design of the fastener is utilized in providing a tool for guiding the fastener into the wood and for countersinking the fastener in the wood. The tool is made in four forms, in one form it is constituted of a holder of square cross section suitably dimensioned so that the top or upper edge of one of the fasteners can be slip-fitted over the end of the holder. An impeller is slidably inserted on the holder and in operable engagement with the upper edge of the fastener. By making the length of the impeller greater than that of the holder and equipping the holder with a handle, the fastener can be guided into the wood and countersunk by striking the protruding end of the im- 2,782,673 P tent dr b. 26, 1957 peller. The tools of the second, third, and fourth forms differ from the first primarily in the holder. The holder of the secondform is a resilient cap having an integrally formed handle. In the third form, the holder and handle are made from a single flat strip while in the fourth form the holder and integrally formed handle are die stamped from a sheet of resilient material.
The invention will appear more clearly from the following detailed description when taken in conjunction with the accompanying drawings showing by way of il lustration the preferred embodiments of the inventive concept.
In the drawings:
Figure 1 is a plan view of the fastener constructed in accordance with the principles of this invention;
Figure 2 is a View of the fastener taken along 2.2 of Figure 1;
Figure 3 is a perspective view of the fastener shown in Figure 1; v
Figure .4 is a perspective view of the fastener shown in Figure I inserted across a wooden miter-joint; and
Figure 5 is a section along the line 5-5 of Figure 1.
Referring now in greater detail to the fastener shown in the drawing, where like reference numerals indicate like parts, reference numeral 10 indicates the fastener, and 11 a miter-joint.
The fastener 10 is constituted of a substantially fiat body portion made from any suitably rigid material. However, by using the later described tools, the fastener 10 can be made from less rigid material than that .now used for making similar fastener but of different design. The aforementioned body portion is turned laterally along the vertical center line 12 until the included angle between the sides is a right angle. Of course, each turned side is of equal length and adjacent the free end one side is turned laterally inwardly along the line 13 and the opposite side along the line 14, and the turned end extremities forming a right angle with the respective sides. Thus, the sides between the vertical center line and the lines of turning 13 and 14 form two sides of a square. The fastener has an upper edge 15, a central tooth 16, an outer tooth 17, and an intermediate tooth 18.
The outer edge 19 of each half portion 16 of the central tooth is substantially vertical or parallel to the vertical center line 12 while the inner edge 20 extends upwardly from a point on the outer edge of each portion of the tooth to a common point on the vertical center line 12. The tip or point of each half of the central tooth is curved outwardly relative to the plane of the side as illustrated. The shape of the edges of the central tooth portions draw the two parts of the miter-joint together along one line while the outwardly curved surface of each portion of the tooth draw the joint together along other lines. Either could be used separately but in combination provide a miter-joint of high quality.
Each outer tooth 17 is of V-shape withthe point of the tooth on the line of turning 13 or 14 as the case may be. The inner edge 21 of each outer tooth is inclined inwardly and upwardly from the line of turning to a point on a line 22 parallel to the center line 12, the line 22 forming the remainder of the inner edge of each outer tooth. The outer edge of each outer tooth extends outwardly and upwardly (Fig. 4) from the bottom of the edge 21 to intersect the edge 23.
Intermediate each portion 16 of the central tooth and outer tooth 17 is an intermediate teeth 18 of V-shape but having a height less than that of the central and outer teeth. Each intermediate tooth 18 serves to part the wood and thereby facilitates the entrance of the web 24 of the fastener into the wood.
What is claimed is:
