4 Claims.
This invention relates to tools, and more particularly to one which is adapted for rigidly connecting wire articles, such as bed-spring coils, etc., to `grooved border wires, although not limited thereto.
It is common practice, in the manufacture of bed-springs, to connect the outside edges, or 'convolutions, of spring units to a grooved border Wire, in which they are adapted to seat. The
grooved border wire is then upset, or deformed, making a rigid connection. The upsetting of the grooved border wire is only accomplished with considerable diculty when using the various devices of the prior art. Y
"515 In my Patent No. 2,017,039, dated October 15, 1935, `entitled Tools, I have disclosed a device l for upsetting grooved border wire in a very expeditious manner, The tool of this patent is one which is intended to be operated by hand, and
V20 is accordingly of relatively light construction.
It is among the objects of the present invention to provide a novel heavy duty tool for assembling elements of the type referred to in a very simple and easy manner.
Another object is the provision of a device of the class described which effects the upsetting of the grooved border wire without necessitating the use of the hands of the operator of the device.
These and further objects will be apparent after v `30 referring to the drawings, in which:
Figure 1 is a sectional elevation of the device of the invention.

Figure '7 is a sectional view on the line VII-VII of Figure 3.
Figure 8 is a view similar to Figure 7 but showing some of the elements of the device in other positions.
Figures 9 and 10 are enlarged sectional details.
Referring more particularly to the drawings, the numeral 2 designates a vertical sleeve which is supported by suitable legs 3, the latter being provided on their lowermost extremities with 'conventional casters 4.
. 55 The sleeve 2 has a central bore 5 at the bottom The housing 9 is dis-` posed at a height which is suitably accessible to a A workman and provided on its upper end with an outwardly extending flange I2, and two pairs of horizontal arms, as at I3 and I4, which extend in opposite directions.
The arms i3 on the housing 9 carry a pin I6 on their outer extremities. A pair oi cooperating upper and lower jaw members are pivotally supported by the pin i6, as at I'I and IB, respectively. The outermost ends of the jaws I'l and I8 are recessed on their adjacent faces, as at I9, in order that each may receive a die member 20. Each of the die members 29 is slotted at right angles to the axis of the pin I6, as shown at ZI, to receive a pin 22, which prevents its displacement.
The die members 20 are held against lateral movement toward the pin I6 by means of wedges 24, one of which is disposed in each of the recesses I9. The upper and lower jaws l1 and I8, respectively, are so shaped between the pin I6 and theiru outer extremities as to receive a bar 25, which is concaved on its outer face. The bar is secured to the outer ends of the arms I3 by means of capscrews 23.
A pair of links 39 are pivoted, as at 3|, to the ends of the upper and lower jaw members Il and i8, respectively, which are most adjacent the housing 9. The adjacent ends of the links are connected together by means of a pin 32, the ends oi which are sldably disposed in suitable slots, or grooves, 33 on the inner faces of the arms I3.
. A pin 34 is carried on the outer ends of the arms I4, and pivotally supports a lever 35. A link 36 is suitably connected on one of its ends to the pin 32, which connects the link 39, and on its other end to the lever 35 by means oi a pin 31. The pin 3l is disposed in alinement with the bore of the housing 9, and has connected thereto a downwardly extending operating rod 39. The link 36 carries an adjusting screw 40 for preventing its excessive downward movement toward the flange I2 on the housing 9, with which it makes contact, and is suitably maintained in adjusted position by means of a lock-nut 4I.
The outer ends of the arms i3 are horizontally slotted, as at 42, to receive a pin 43 between the upper and lower jaw members I'I and I8, respectively. To this pin 43 there is pivoted a pair of forwardly extending curved links 44, one on each side of the upper jaw member I'I. A bifurcated lever 46 is pivotally mounted on the pin i6 which carries the upper and lower jaw members Il and I8, respectively. Each of the arms i3 carries a pin 49 which extends into a curved slot 59 in each of the curved links 44. The offset portion 48 of the lever 46 has a curved slot 52 through which the pin 43 extends. It will be seen from Figures 5 and 6 that the backward and forward movement of the lever 46 causes the forward ends of the links 44 to register with the recesses I9 in the upper and lower jaw members I'I and I8, respectively. This permits the links 44 to effectively hold the outside convolution of a coil spring in a groove in a border wire which is disposed between the die members 20.
It will be understood by those skilled in the art that the operating rod 39 is readily susceptible to being vertically reciprocated at proper intervals by suitable power, or one of a number of manually operable devices which do not require the use of the hands of an operator. One form of such a manually operable device is illustrated as embodying a foot-control. According to this embodiment, the flange 6 of the sleeve 2 carries an attached plate 60 which is provided with downwardly extending arms 6I to which there is pivoted, as at 62, a suitable foot-lever 63. This footlever 63 carries on its end opposite its pivot 62 the usual pedal portion 64. A small-diameter tube 65 is connected to the foot lever 63 intermediate its ends, as shown at 61.
This small-diameter tube 65 extends into the bore 5 of the sleeve 2 and is screw-threaded on its upper extremity, as shown at 68. The lower end of the operating-rod 39 is screw-threaded, as at 39a, to cooperate with the screw-threads 68 of the tube 65. The pitch of the threads of the bore of the housing 9 and the cooperating threads 8 on the sleeve 2 is the same as the pitch of the threads 68 of the tube 65 and the cooperating threads 39a of the operating-rod 39, respectively. This provides for the adjustment of the housing 9 with respect to the upper end of the sleeve 2 without causing the disconnection of the operatingrod 39.
A nut 'Illa is carried on the threaded portion 69 of the tube 65. A spring II is carried on the tube 65, below the collar 19, and is confined from downward movement out of the bore 5 of the sleeve 2 by means of a plug l2, which is screwthreaded, as at 13, into the bottom of the flange 6. The plug 'I2 is apertured, as at 14, to receive the tube 65. The lower end of the spring 'II is held in the collar 12a.
In operation: A border wire A (Figures 9 and 10) having a deformable groove B therein is disposed between the upper and lower jaw members I'I and I8 and against the concaved face of the bar 25 with the groove B extending outwardly.
The outside convolution C of a coil spring is suitably disposed in lthe groove B of the border wire A, and the lever 45 is moved toward the housing 9, thus moving the links 44 to hold the convolution in this position.
The foot lever 63 is depressed, causing the small-diameter tube 65 to move downwardly against the spring 1|. The downward movement of the tube 65 causes the similar movement of the operating rod 39 to which it is connected. This moves the pin 3l downwardly and causes the link 36 to move the pin 32 toward the pin I 6 which is held between the arms I 3. This movement of the pin 92 in the groove 33 causes the links 39 to force apart the ends of the upper and lower jaw members I'I and I8, respectively, which are nearest the housing 9. This moves the die members 29 toward each other, and causes the border wire A to be upset around its groove B, as shown at X in Figure 10, whereby the outside convolution C of coil spring is securely held. Deformation of the groove B is continued until the adjusting screw 4D on the link 36 comes into contact with the flange I2 on the housing 9. The wedges 24 which hold the die members 20 in the recesses I9 are so constructed and arranged that the distance between them is equal to the diameter of the border Wire A when the upper and lower jaw members I'I and I8 are in closed position. It will thus be seen that if one die member 20 performs its function on the border wire A before the other die member, the border wire A engages the wedge and prevents further travel in that direction. This insures equal upsetting of the border wire A on both of its sides.
After the upsetting of the border wire A around its groove B is completed and the outside convolution C of the coil spring suitably secured therein, the foot lever 63 is released, which permits the spring 7| to expand. This moves the operating rod 39 upwardly, withdrawing the links 30, and forces apart the ends of the jaw members II and I 8.
The lever 46 is then moved away from the housing 9, causing the links 44 to move backwardly and away from the outside convolution C of the coil spring, consequently releasing the latter. It is to be understood that the present invention contemplates the provision of a suitable power unit for reciprocating the operating rod 39, in lieu of the foot lever 63.
While I have shown and described certain other specic embodiments, it is also to be understood that various modifications may be made Without departing from the scope of the invention, as defined by the following claims.
