UNITED STATES JOHN H. WARE, OF LOS ANGELES, CALIFORNIA.
SWAGE.
Application filed August 16, 1923. Serial No. 657,753.
To all whom it may concern:
Bel it known that I, JOHN H. 1WARE, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and St-ate of'California, have invented a new and useful Swage, of which the following is a specification.
The device forming the subject matter of this application is a casing swage, of that general form shown in Patent No. 980,079 granted on December 27, 1910 to Ryland W. Eames.
Sundry improvements are proposed in the structure shown in the patents above identified, one of these improvements being a means for preventing the base and they anvil of the swage from swinging with respect to Vcach other, during; the operation of the swage, and during the insertion of the device into the article which is to be swaged, as well as during the removal of the device therefrom.
Another object of the invention is so to construct the device that a conve-nient and l strong place of attachment may be provided for the operating member whereby the swage is introduced into the tube which is to be'swaged.
Another object of the invention is to strengthen the construction of the base portion of the swage.
The foregoing objects, having been ystated generally above, will be understood ,better when the following description is read in connection with the drawing. Y
lt is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains. v
TWith the above and other objects in view, which will appear as the description proceeds, the invention resides inthe combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that within the scope of what is claimed, changes in the precise embodiment of the inventionvshown canY be made without departing from the spirit of the invention.
In the accompanying drawings Figure 1 shows in side elevation, a casing swage constructed in accordance with the invention, parts being broken away; Fig. 2 is a longitudinal section; Fig. 3 is a transverse section on the line 3-3 of Fig. 1,
the line 2-2 in Fig. 3 indicating the cutting plane on which Fig. 2 is taken; Fig. 4 is a transverse section on the line 4--4 of Fig. v1; Fig. 5 is an elevation illustrating the operation of the swage with respect to a casing.
Since the device forming the subject matterof this application is an improvement on the casing swage shown in Patent No. 980,079, the description will open with an enumeration of the parts common to the two devices, reference numerals being taken, so far as pos'sible, from Patent No. 980,079, and notice being given when the description no longer alludes to that which is old, but refers to that which is new and characteristic of the present application.
The device forming the subject matter of this application comprising cooperating members, one of which is in the form of a trough-shaped base .1 having a cylindrical intermediate bearing surface 3, and inclined yend surfaces 4'. The base 1 is supplied with an internal radial projection 9, reinforced by longitudinal webs 11 which are joined to the base 1. The base 1 has cross walls 25 equipped with projecting ears 16 wherein a first shaft 17 -is j ournaled, the shaft carrying a worm 18. The shaft 17 is adapted, as indicated at 26, to receive a crank 19 or other means whereby rotation may be iml parted to the shaft. A second shaft 12 is provided, and is disposed at right angles to the .first shaft 17, the shaft 12 being rotatably mounted in the projection 9 of the base 1, and carrying a worm wheel 111 resting on the projection 9, the worm wheel meshing with the worm 18 on vthe shaft 17.
The swagepembodies an anvil2 having a cylindrical intermediate bearing surface 5 and inclined end surfaces 6. The Vanvil 2 has an internal radial projection 7 reinforced by webs 11a. One end of the second shaft 12 is threaded at 13 into the projection 7 of the anvil 2.
The description of the operation of the device may be dismissed briefly,- the numeral 21 denoting in Fig. 5, a casing .or tube which has a dent 20.` It is obvious that if the swage is introduced int-o the tube 21, and that if relative movement between the base 1 and the anvil 2 is brought about, through the instrumentaliy of the shaft 17, the worm 18, the worm wheel 14 and the screw shaft 12, the dent 20 will be pressed outwardly.
Having thus set out with suflicient eXactness, those parts which are old, it remains to discuss the features which characterize the CFI structure forming the subject mattei' of this application.
Thus, it is proposed to strengthen the trough-shaped base 1, and, with this end in view, the webs l1 are joined to the cross walls 25. The base 1, further is strengthened by the provision of longitudinal buttresses 27, extended outwardly from,V the walls 25 and joined to the walls and to the base 1.
Passing to a more important improvement, it may be that in the operation of tie casing swage as shown in Patent No. 980,979, coi'isiderable difficulty has been experienced, by reason of the fact that the base 1 and the anvil 2 do not always stand in parallel relation. l-l'aving this objection in mind, the trough-shaped base 1 is provided with an internal projecting arm 28, carried byone of the buttresses 27, the arm being received between inwardly projecting flanges 29 on the anvil 2. lt will be obvious that the interengaging elements represented by the parts 28 and 29 prevent the base 1 and the anvil 2 from swinging out of parallel relation, without, however, in,- terfering-with the relative transverse movement between the members 1 and 2, when the dent 20 is removed from the casing 21 in the manner hereinbefore set forth. The flanges 29 have an additional function, in that they form a place of attachment for the means whereby the swage is moved longitudinally within the casing 21. Thus, a securing element 30, such as a bolt, is mounted in the flanges 29, an operating member 31, sometimes in the form of a rod, extending between the flanges 29 and being mounted pivotally, as at 32, upon the securing element. By means of the operating member 31, the swage may be moved lengthwise in the casing 21, in order to place the swage properly with respect to the dent 2O and to provide for a removal of the swagc.
The arm 28 on the base 1 must operate with the flanges 29, the flanges 29 carry the operating member 31, the operating member must be located closely adjacent to one end of ther swage, the arm 28 is carried by one of the buttresses 27, and the said buttress is connected, for reinforcement, to the adjoining cross wall 25. ln view of all of the foregoing, it is obvious that the cross walls 25 must be spaced apart more widely than are the corresponding cross walls in the patent mentioned. Since the cross walls 2,5, and consequently t-he ears 16, are spaced more widely apart than are the corresponding elements in patent No. 980,079, the ends of the worm 18 do not engage directly with the walls 25, to hold the shaft 17 against longitudinal movement, sleeves iXi-3 being jonrnaled on the shaft 17 and being located between the ends of the worm 1,8 and the ears or bearings 16, to hold the shaft '17 against longitudinal movement, and in the position shown in Fig. 2 of the drawings.
W' hat is claimed is 1. A device of the class described comprising cooperating members; means for moving said members apart; interengaging lements on said members coacting to prevent. said members from swinging'on said means, and to hold said members in parallelism; and means for moving the device bodily, said means being connected to one of the aforesaid interengaging elements.
2. ln a device of the class described a trough-shaped base provided with an internal projection and having cross walls, the base being equipped with longitudinal webs connecting the projectionV with the walls, and being' supplied with a buttress extended outwardly from one wall, the butti-ess having an arm; an anvil cooperatingwith the base; means for moving the anvil and the base apart, said means comprising a part mounted in the projection; and an element on the anvil wlierewith the arm cooperates to prevent relative swinging movement of the base and the anvil on said part.
A. device of the class described, constructed as set forth in claim 2 and further characterized by the provision of a member for moving the device, said member being connected to said element on the anvil.
4. A device for swaging dents out of tubes, comprising cooperating members which are transversely curved on their outer surfaces to conform to the internal cross section of the tube to be swaged, the length of said members vbeing appreciably greater than their width; mechanism located between said members for forcing them apart, said mechanism comprising a screw shaft rotatable in both of said members and disposed approximately at rightangles to thv length of said members, said members be-V ing provided with. inwardly projecting parts which cooperate to prevent said members from swinging with respect to each other on the screw shaft and getting out of alineinent wit-h each other.
ln testimony that l claim the foregoing` as my own, I have hereto affixed my signa ture in the presence of two witnesses.
