This invention relates to splining devices for pressing splines into grooves. It is particularly adapted to framing screens, and will be described, for illustration only, as applied to that.
One of the objects of the invention is to provide an improved simple, effective and economical machine for applying splines.
Another object is to provide a splining device which can easily be operated by unskilled and in experienced persons.
Another object is to provide a splining device which will simultaneously insert a screen cloth in a groove and apply a spline to the groove.
Other objects and advantages will be evident from the following description and accompanying drawings,
In the drawings:
Fig. 1 is an isometric view of a screen framing machine embodying one form of my invention;
Fig. 2 is a fragmentary sectional view, on an enlarged scale, showing the splining roll in elevation;
Fig. 3 is a section on the line 3-3 of Fig. 2;
Fig. 4 is a side elevation of the principal parts of the machine;
Fig. 5 is a view partly in section on the line 5-5 of Fig. 4 and partly broken away, indicating diagrammatically three positions of the splining roll;
Fig. 6 is an end elevation of the driving motor, two positions being indicated diagrammatically; and
Fig. 7 is a plan of the apparatus shown in Fig. 4.
As shown in Figs. 1 and 2, a screen frame H) has frame members [2 each having a groove 14 into which the edge of a sheet of screen cloth I6 is pressed and secured by a spline [8. The spline is usually an elastic round rod of rubber or suitable synthetic plastic material which is deformed slightly as it is pressed into the groove. The spline wraps the screen cloth around it, and expands against the sides of the groove to hold the screen cloth in place. So much is known.
The invention provides improved means for pressing the spline into the groove. It includes a support having a sufficiently extended surface to hold conveniently a screen frame, such as a screen door. The supporting surface may include the top of a table or bench 20, with or without an additional surface such as 22 of an attachment 23 secured to the table. An antifriction roller 24 is mounted on an axis below the surface of the support and parallel to it. The periphery of the roller projects slightly above the supporting surface at the point where the roller is located. Thus in Fig. 2 the surface of the roller is slightly 2 Claims. (01. bill-109) above the surface 20 of the attachment 23, and both the roller and the table top form supports for the frame.
A splining roller disk 26 having its plane perpendicular to the screen frame and parallel to the groove I4 is arranged so that it can be pressed against the spline, as shown in Figs. 2 and 3, and can be rotated as shown by the arrow in Fig. 3 to force the spline progressively into the groove. As the spline enters the groove it wraps the screen cloth around it, stretches the cloth over the frame and wedges the cloth and itself in the groove. In this operation the splining roll clamps the frame between itself and the roller 24, and as the 'splining roll turns it moves the screen from right to left as seen in Figs. 1 and 3.
The invention includes improved means for supporting and driving the splining roll. A driving motor 30 and motor support 32 are mounted entirely outside the supporting surface 20 or 22. That is, geometrically speaking, the motor and its support are located outsidethe projection of the frame-supporting surface in the direction perpendicular to the plane of the supporting surface. The motor may, if desired, include any suitable reducing gear, mounted in the housing 34. If so, the reduction gear is included within the term motor as used herein. The motor carries an elongated shaft 36 which projects over the screen-supporting surface 20 or 22, that is the shaft projects within the projection of the surface parallel to the plane of thesurface. At the free end of the shaft the splining roll 26 is mounted, so as to rotate with the shaft. With the parts in the position shown in Figs. 2 and 3 the shaft 36 (the axis of the splining roll 26) is parallel to the axis of the supporting roll 24, and the two rolls are in alignment in the direction perpendicular to the table.
As shown in Figs. 4, 6 and 7 the motor is mounted on the support 32 by pivots 36 so located that the weight of the motor, shaft and splining roll normally tends to tip the motor to the dotted line position 38 (Fig, 6). When in this latter position the splining roll is raised from the table, to the dotted line position 40 in Fig. 5, out of operative position, leaving the table clear for the placing or removal of a screen frame.
Near the end of the elongated motor shaft, and adjacent the splining roll, is a shaft bearing 50 mounted on an arm 52 secured to the motor support 36. A gooseneck 54 is pivoted at its upper end to the bearing, passes around the edge of the table, and is pivoted at its lower end to an operating rod 55 adjustably secured to a pedal 58 (Fig. 4) by which the splining roll is brought into operative position against a spline on the screen frame. The lower end of the gooseneck is in vertical alignment with the bearing 50. The force applied by the operator to the pedal 58 acts at a point as near to the splining roll as possible, and acts along a line adjacent and parallel to the line of motion of the splining roll. This force presses the spline into the groove. As the splining roll is brought into operative position the motor pivots on its support, the splining roll successively reaching the positions Eli and 6! shown in Fig. 5. In position (it the roll first contacts the spline; in position M the spline is seated in the groove. When the splini'n'g roll reaches posi tion 64 a switch 82 (Fig. 6) starts the motor and the roll progressively rolls the spline into the groove. By the arrangement of the invention all force required to press the spline into the groove is transmitted to the apparatus closely adjacent the splitting roll. This permits light pivot bearings and a light motor shaft to be used.
The supporting surface for the screen frame is unobstructed to its edges to facilitate insertion and removal of screens and movement of the screens by 'tlresplining roll. Preferably an act-- justable guide W is secured to the edge of the supporting 'sucfa'ce by any desired means, as by set screws H which fasten it to the frame members 23. The'cffset on the gooseneck is wide enough to permit screens having very wide mar gins to be framed, such as doors, the guide being set to tiring the spline groove of any particular frame under the splining roll. Adjustment of the operating rod 56 adapts the machine to screens of different thicknesses, and adjustment of the screw stop "Hi (Fig. 6) insures closing of the switch 62 at the proper instant. I
In operation, the screen is placed against the guide on the table with one end of the spline groove of one side'or frame member on the roller '24. The screen cloth and ispiine are placed in position and the pedal 58 depressed. as far as it will go. The motor is thus tilted, the spline roll is brought against the spline and seats the spline in the groove, the motor is started, and the spline is rolled progressively into the groove. The rotation of the splining roll movesthe screen along the table until the spline is rolled into the entire length of the groove. The pedal is then released, automatically stopping the operation to permit the'corner to be turned for insertionof the spline in the next side. The motor may be provided with a mainswitch it in series with the switch it. and may also be provided with-a reversmg switch it by which the screen rail may be rolled back and forth if desired.
Conveniently the entire apparatus may constitute an attachment which can be securedreadily to any suitable table or bench. As shown screw clamps 82. Adjustable legs 84 support the motor base 36.

A framing device comprising in combination a support having an extended fiat surface adapted to support a screen frame, a tiltable motor disposed outside of the perpendicular projection of the supporting surface, an elongated drive shaft carried by the motor and rotatable by the motor, the shaft extending within the perpendicular projection of the supporting surface, a splining roll on the shaft, the roll being movable by tilting of the motor toward and away from the supportmg surface along a line intersecting the surface, a bearing on the shaft adjacent the roll, an offset 'l'inl: connected to the bearing, and means on the side of the surf-ace opposite to the bearing connected to the link for tilting the motor and urging the roll toward the surface, said link and last mentioned means being adapted to exert force on the bearing along :a line passing through the surface and adiacent the line of motion of the roll.
