Definitions
- This invention relates to a method and appa ⁇ ratus for fastening together the frame elements of a picture frame or the like, and to a frame formed by the method and apparatus.
- the frame elements In the production of frames of the type used, to mount picture or mirrors and similar objects, and in the production of panel doors for kitchen cabinets and the like and the frames for the door openings, the frame elements usually are formed with end sur ⁇ faces oriented at 45° angles with respect to the lon ⁇ gitudinal axis of the frame elements with the grain of the wood extending along the length of each frame element and the angled end surfaces of each frame elements are matched together with a similar angled end surface of an adjacent frame element to form a 90° mitered joint, and the frame elements are con ⁇ nected together by a fastener.
- One process used for fastening mitered joints is to insert at least one nail into the outer edge surface of one frame element through that frame element, through the mitered joint, and into the adjacent frame element. - As the fastener is driven
- a second fastener can then be driven from the edge surface of the ad ⁇ jacent frame element through the mitered joint, and this usually forms a firm connection between the frame elements .
- Some disadvantages of this type con ⁇ nection procedure are that the head portions of the fasteners are visible at the edge of the frame when the frame is hung on a wall, or if the fasteners are counter sunk into the frame elements the holes or the putty covering the holes are visible, a multiple number of fasteners are required for each joint to form a stable frame, there is a hazzard that the fasteners will hit each other as they are driven into the frame, and if the frame is held in a jig and fasteners are driven simultaneously through both of the frame elements at the corner of . the frame, two fastener tools are required for the process.
- Another process for joining frame elements together in a mitered joint is to place the angled end surfaces of the frame elements together to form the mitered joint and then to insert a staple or similar fastener into the back surfaces of the frame elements at a right angle with respect to the sur- faces of the frame elements so that the fastener straddles and therefore connects together the frame elements. Since the movement of the fastener into the sufaces of the frame elements usually does not tend to draw the frame elements together, the fir - n ⁇ ss of the connection between the frame elements depends upon the operator ⁇ s technique, and if the operator is not diligent in pressing the frame ele ⁇ ments together during the fastening procedure, a loose joint is formed.
- OMPI together in a mitered joint is to form a kerf in each frame element adjacent the mitered joint on the unex ⁇ posed surfaces of the joint and extending outwardly from the inside surfaces of the joint and then inser ⁇ ting a clamp into the kerfs.
- a disadvantage of this process is that it requires additional labor and time, and therefore is expensive.
- the present invention comprises a frame fastener for connecting together the frame elements of rectangular frames such as - picture frame and the like to form mitered joints at the corners of a rectangular frame, wherein the frame elements are placed in and held by a right angle clamp assembly so that the 45° angle end surfaces of the frame elements are held in abutment with each other, and a fastener is inserted into the back or unexposed surfaces of the frame elements.
- the fas ⁇ tener straddles the joint between the frame elements at an angle from the unexposed surface near the outer corner of the joint and is sloped toward the inside of the right angle formed at the corner of the frame joint.
- the right angle clamp assembly includes sta ⁇ tionary clamp elements for holding the inside sur ⁇ faces of the frame elements and movable clamp ele ⁇ ments that move toward and away from the inside clamp elements for bearing against the outside edges of
- a brace is movable against the outside surfaces of the frame elements at the joint opposite the surfaces of the frame elements into which the fastener is to be inserted, and the fastener tool is positioned with its discharge opening at the plane where the frame elements are to be located when gripped by the right angle clamp assembly.
- the mov ⁇ able clamp elements are actuated by pneumatic cylin ⁇ ders, and a pressure responsive switch responds to the gripping by the movable clamp elements of the frame elements to actuate the fastener tool, so that
- the fastener tool does not discharge a fastener un ⁇ less the frame elements are properly gripped in the right angle fastener assembly.
- the fastener tool is tiltable with respect to the right angle clamp assembly so that the fas-
- 20 teners can be inserted at shallow angles into the frame elements formed from soft wood, or the fas ⁇ tener tool can be tilted to insert the fasteners at a steeper angle into the frame elements formed of harder woods.
- the frame elements are characterized by having their 45° angled end surfaces pressed together in a mitered joint as a fastener is inserted at an angle sloped with respect to the back surfaces of the frame elements toward the inside of the right
- Another object of this invention is to pro ⁇ vide a frame fastener which forms tight mitered joints in rectangular frame structures, with the fastener- for the joints straddling the. joints and ex ⁇ tending through the back surfaces of the frame ele ⁇ ments at an angle sloped toward the inside of the right angle formed by the frame elements .
- Another object of this invention is to pro ⁇
- a frame fastener for forming picture frames and the like including a right angle clamp assembly and a cradle for a fastener tool which locates the dis ⁇ charge opening of the fastener tool at the position where the mitered joint is to be formed by the clamp - ⁇ • 5 assembly, with the cradle being tiltable so as to tilt the fastener tool about an axis extending approximately through the discharge opening of the fastener tool so as to insert fasteners into strad ⁇ dled relationship about the joint and at variable 0 angles with respect to the surface of the frame.
- Another object of this invention is to pro ⁇ vide a frame fastener -for connecting together the mitered joints of picture frames and the like, where ⁇ in the movable clamp elements of a right angle clamp 5 assembly are urged against the frame elements of the picture frame by pneumatic cylinders, and in response thereto, a fastener tool discharges a fastener that penetrates the surfaces of the frame elements at the mitered joint to connect the frame elements 0 together.
- Another object of this invention is to pro ⁇ vide a method and apparatus for rapidly and reliably connecting together the frame elements of a picture frame or the like in a firm mitered joint so that the 5 fasteners are inserted through the back or unexposed surfaces of the picture frame and the fasteners are not visible when the frame is hung on a wall surface.
- Another object of this invention is to pro ⁇ vide a sturdy picture frame which has fasteners in- serted into the back surface of the frame and which, as they are being inserted, tend to draw the frame elements together in a tight mitered joint.
- Another object of this invention is to pro ⁇ vide a method of inserting fasteners into the mitered joint of a picture frame or the like wherein the fas ⁇ tener straddles the joint and is .inserted from the unexposed surface of the joint at an angle which uses the process of cutting through the wood grain to gather the frame elements tightly together.
- Another object of this invention is to pro ⁇ vide an improved means for fastening a miter joint of a frame by inserting the fastener into the joint from an"unexposed surface of the joint so as to avoid dam ⁇ aging any exposed surfaces of the joint.

- attitude of the cradle yoke 108 with respect to support 100 and 101 can be adjusted by loosening bolts 120 and 121 and ' sliding the slide straps 112 and 113 about the bolts and then tightening the bolts.
- OMPI _ are received in the U-shaped slot 28 of mounting plate 24.
- Support bracket 124 is located between the upper ends of side legs and 110 and 111 of cradle
- Fastener tool 13 rests in and is mounted to fastener tool cradle 12 by placing the head portion of the fastener tool in the cradle yoke 108 with the discharge opening 125 of the fas-
- the fastener tool usually is rigidly connected in the fastener tool cradle 12 by bolts extending through the support bracket 124 into the tool and by bolts extending through base 109 into the tool.
- the fastener tool can be pivoted substantially without moving discharge opening 125 with respect to the plane of the work surfaces 36, 37.
- the discharge opening 125 moves in a plane parallel to the plane of the work surfaces 36 and 37 since the cradle braces 29 and 30 and support arms 100 and 101 extend paral- ' lei to the plane of the work- surfaces 36, 37.
- Air under pressure is supplied to frame fas ⁇ tener 10 through a conduit from a compressor (not shown) connected to fitting 127, with the air com ⁇ municating directly with the plenum (not shown) with ⁇ 0 in fastener tool 13.
- the T-connector 128 communi ⁇ cates with fitting 127 and with air supply conduit 130 so as to supply the- pressurized air to one side of foot control valve 131.
- Foot control valve is lo ⁇ cated on the floor at the operator's position adja- cent frame fastener 10 and includes valve housing 132 and pedal 134 pivotally mounted to the housing 132.
- the valve spool (not shown) is positioned within valve housing 132 and controls the supply of air pressure from air supply conduit ' 130 to air control conduits 135, 136.
- air conduit 135 communicates with branch conduits 138, .139 and 140, and these conduits each communicate with one end of a pneumatic cylinder 74, 75 and 96, so that when 5 pressure is received in a . branch conduit 138-140, each cylinder retracts its cylinder rod 76, 77 and 95. This tends to close the movable clamp elements 54 and 55 toward the stationary clamp elements 50 and 51 and to move the brace foot 88 toward the plane of work surfaces 36 and 37 of the right angle clamp assembly 11.
- T-connector 128 is also connected to air supply conduit 145, and air supply conduit 145 is connected to branch conduits 146, 147 and 148, and air supply conduit is also connected to control valve 149.
- Branch conduits 146 and 147 each communicate through an opening 150 and 151 formed through movable clamp elements 54 and 55, respectively, while branch conduit 148 is connected to one end of air opening 152 formed through cylinder support arm 71.
- the arrangement is such that the air under pressure moving through air supply conduit 145 communicates with control valve 149, but the air is also continu ⁇ ously bled to the atmosphere through conduits 146, " 147 and 148.
- the frame elements 2 and 3 are rectilinear elements each having 5 their end portions 4 and 5 formed at a- 45° angle, and the angled end portions are placed in abutment with each other, causing the frame elements to form a 90° angle with respect to each other.
- the particular fastener 168 illustrated herein is approx ⁇ imately U-shaped in cross-section and is of a breadth sufficient to straddle the joint formed between the rectilinear frame elements.
- Fastener 168 includes 5 central webb 169 and side flanges 170 and 171, with openings 172 formed in central webb 169.
- the fas ⁇ tener is inserted into the back surface of the frame elements, from beneath the frame as the fastener is discharged from the discharge opening of the fastener 0 tool 13, with one flange 170 located on one side of the seam of the joint and with the other flange 171 on the other side of the' seam of the joint.
- the fas ⁇ tener 168 is inserted at an inclined angle with re ⁇ spect to the back surfaces of the frame elements so 5 that it is inclined toward . the inside of the right angle formed by the frame elements.
- the brace foot 88 also pivots toward the mitered joint so that the surfaces of- the joint- are further urged toward a common plane and the frame elements are braced against the impact of the fas ⁇ tener 168 as the fastener enters the frame elements. Since the flanges 170 and 171 of the fastener (Fig.7) are tapered, and since the fasteners 168 are inserted at an angle sloped toward the ' inside of the right angle formed by the frame elements (Fig. 8), the flanges 170 and 171 ' tend to be deflected apart from each other as they engage the grain 9 of the wood, thereby tending to draw the grain together. There ⁇ fore the frame elements are drawn together as the fastener enters the material of the frame elements, thus assuring firm abutment of the frame elements.
