Claims. (Cl. 219-1053 This invention relates to a door casing machine.
The object of this invention is to provide a machine for setting thermosetting adhesive, that is, adhesive requiring heat after its application for its setting in the joints in said casing, by applying heat generated by radio frequency waves in said adhesive.
Another object of this invention is to provide a heat applicator which in addition exerts considerable pressure on the joint in a door casing during the application of heat to the same, so that the adhesive setting operation is done under considerable pressure on said joint. Another object of this invention is to provide a device of the type described which is easy and convenient to operate, and which is simple in construction and etficient for the purpose intended.
Another object of this invention is to provide a device of the type described which is cheap to make and inexpensive to maintain.
Other objects and advantages will appear as the specification proceeds and the novel features of the device will be particularly pointed out in the claims hereto annexed.
In this specification and the annexed drawings, the invention is illustrated in the form considered to be the best, but it is understood, that the invention is not limited to such form; and it is also to be understood that in and by the claims following the description, it is desired to cover the invention in whatsoever form it may be embodied.
This invention is illustrated in accompanying drawings forming a part of this specification in which:
Fig. 1 is a plan view of the device.
Fig. 2 is a side view of the same, some parts being broken away to show the inner parts thereof.
Fig. 3 is an enlarged side view of the applicator shown as applied to a decreasing.
Fig. 4 is a front view of Fig. 3, and
Fig. 5 is a plan view of a door casing.
In detail, our machine includes a table 1 having a top 2 and supported by suitable legs 3. The table 1 supports a radio frequency generator 5, which may be of any type capable of producing enough energy for the purpose as hereinafter shall be described in detail. A tuner 8 is connected with said generator 5 by wires 9 and 10, which tuner is used to regulate the impedance of the radio frequency generator to correspond with the load involved in the operation.
The table 1 also carries a pressure and heat applicator 15. The latter is secured to the free end of a lever 16, the other end of which is fulcrumed to a pair of standards 17 with freedom of swinging. A long shaft 19 pierces said lever, the top 2 of said table and connected to a foot pedal 20, one end of which is fulcrumed to the table legs 3 and the other free end 21 extends beyond the front of said table. A coil spring 23 is interposed around the shaft 19 between the lever 16 and the top 2 of the table 1, which spring urges said lever upwardly and away from said table top. Another coil spring 25 connects said foot pedal with a table shelf 26 provided under the top 2, which spring pulls said pedal upwardly.
The pressure and heat applicator 15 consists of an electrode 30 which is preferably made of copper or aluminum in form of a comparatively long bar 31, having a flange 32, located in the middle of the top of said bar and extending longitudinally over the central portion thereof.
The electrode 30 is secured to a triangular plates 34 secured to the of bolts 33. The latter The angles 40 are securely attached to the lower surface of the lever 16 at its free end. The pivot 36 may swing between said plates in a plane transverse to the electrode 30. Hence, said electrode may swing forward and backward about the bolt 35 and to the right and to the left about the bolt 41. i
The electrode 30 is connected by a wire 43 secured thereto by a screw 44 to the tuner 8. Directly under said electrode 30 is another metallic electrode 48 in form of a plate located in the top of the table 1 and covered by a sheet 49 of special adhesive 'repellant plastic. by a wire 50.
A push-button switch 53 connected to the frequency generator 5 by wires 54 and 55 is provided in the front of the table. The switch is secured to 'a stand 57 attached to the shelf 20, and operated by a lever 60 the lower end of which is hinged to said shelf in close proximity to said stand 57.
' An operator by pressing moves the heat applicator shaft 19 and the lever may deem desirable he the foot pedal 20 downwardly 15 downwardly through the 16. At any time as the operator may press by the knee the lever 60, and thereby put the frequency generator'into operation. Thus, this machine may simultaneously apply pressure and heat on the joining portions of planks forming a door casing.
Figure 5 shows a corner of said casing consisting of two planks 65 and 66 joined at the right angle to each other, the visible line 67 of junction being at the 45 to the outer sides of said planks. The front side of the planks 65 and 66 is bevelled from the outer side thereof toward the inner side, as shown in Figures 3 and 4.
The planks are joined by a joint 68 denoted by said line 67, a dotted line 69 denoting the continuation of the inner side 70 of the plank 66, and the outer side of the plank 65. This joint is made by cutting a piece off the top of the plank 66 parallel to the bottom leaving a bottom piece 71 and a corresponding piece of the bottom portion of the plank 65 leaving a top piece 72 and placing the latter piece over the piece 71. A layer of thermosetting adhesive is placed between the pieces 71 and 72 before the same are joined.
In order to assemble said planks at the right angle correctly, abutments 75 and 76 are provided on the table in front of said electrode 48. When the planks 65 and 66 are placed against said abutments they form the right angle and their joint 68 is between the electrodes 30 and 48.
The device operates as follows: the ends of the planks 65 and 66 are fashioned to make the joint 68, and
The electrode 48 is connected to the tuner 8 3 theme-setting adhesive is applied to both surfaces of the joint. The planks 65 and 66 are placed against their respective abutments 75 and 76 so that their ends meet. The applicator 15 is-brought down and placed carefully on the joint as shown in Figs. 3 and 4. The applicator 15 will take an angular position in respect to the top 2 of the table 1, due to the position of the planks in relation to the applicator and also because the incline of the front side of the plank forwardly.
After the applicator 15 has been properly set on the joint 68, the operator presses with his foot the foot lever 20 and thereupon pushes with his knee the lever 60, thus turning the switch 53 on and sending the radio frequencies through the electrodes 30 and 48 and the joint 68. The tuner 8 permits the operator to select the proper impedance so that a proper amount of heat is applied to the joint. The adhesive sets within a few seconds.
This machine is simple in operation, cheap to make and very efficient, reducing the cost of labor to a small fraction of the manual operation.
In "some cases the joint 68 may be on the right side of the line 67, in which case the applicator 15 is swung to the right from its neutral position and over said joint 68. This is made possible by the arrangement of the electrode 30 for swinging in two transverse directions as has been explained in detail heretofore.
