8 Claims.
This invention relates to an improvement in sheet metal stretching vises and is particularly adapted to be used in the straightening of badly damaged dOOls and particularly those of automobile doors which have become bent or damaged due to collision or other accident.
Another object of the invention is to provide a device that will relieve the pressure from the door exerted by the bent portions therein in order to facilitate the return of such doors to their original shapes when straightened by application of a mallet or hammer.
Another object of the invention is to grip and stretch the door as much as is possible while the straightening operation is taking place.
And another object of the invention is to provide a tool which will absorb the pressure normally incurred when a highly resistant object is being straightened.
A further object of the invention is to provide means that are adjustable to accommodate various sizes of doors or other material to be straightened.
Other objects and advantages will become apparent during the course of the following description.
In the accompanying drawings, forming a part of this specification,- wherein like characters. of reference denote like partsthroughout:
Figure 1 is a perspective view of the invention as applied to a bent door;
Figure 2 is a side elevation of the improved tool, with certain parts being shown in section;
Figure 3 is a transverse vertical view taken substantially on line 33 of Figure 2, and
Figure 4 is a transverse vertical sectional view, taken substantially on the line 4-4 of Figure 2, as seen in a direction opposite that of Figure 3.
The difiiculty occurring in straightening badly bent doors of highly resistant material appears to be due to the fact that the pressure exerted by the bend in the door resists the efiorts of a hammer or other tool used to straighten out such hump. In order to overcome this objection, it would appear to be desirable that pressure exerted by the door be relieved so that there will be considerably less resistance to the hammering effect during the straightening process. In order to achieve these ends, the instant invention has been devised.
Referring to Figure l, the tool of the invention is indicated generally by numeral and is shown engaging the end of a door or other damaged object 12. l
As is best illustrated in Figure 2, the tool consists of a sectional housing l4 and Hi. It is to be noted that housing member [4 is tubular and of considerably greater length than housing 16.
Housing I4 is hollow in construction and is open at each end. A suitable bushing l8 threadedly bored along the axial length thereof, is welded or otherwise suitably mounted on the outer extremity of housing member l4. Housing section [6 is open at one end thereof and is closed at the outer extremity by means of a suitable plug 22 welded therein. Housing member 16 is a sleeve and hollow in construction in the manner of housing l4. A screw shaft-24 is rotatably seated within bushing l8 and extends into'housing 14 for a short distance. A suitable actuating crank handle 26 is secured to screw 24 for actuation thereof. Secured to the inner end of actuating screw 24 is an elongated steel shaft 28, shaft 28 being of a diameter closely fitting the inner periphery of housings l4 and I6 and extends through both housings l4 and [6 as is clearly illustrated. It will thus be seen that the shaft 23 and the housing [6 considered together constitute a member-slidingly received within and extensible from the tubular housing l4.
Mounted on housing members [4 and 16 are jclamps 3ll.- Two clamps are used, and as they are identical in construction, a descriptionof one will be applicable for "the other. As is best illustrated in Figures 2 through 4, clamp 30 isof two separate members 32 and 34 arcuately grooved on the inner surfaces thereof and in complementary relation at 36 for retention in non-slipping relation on the respective housing pipes. Clamp members or jaws 32 and 34 are retained in locked position by threaded bolts 38 extending through suitable bores therein. Bolts 38 include headed stops 40 on one end thereof and mount on the opposite extending end a clamping plate or bar 42. Door' I2 is adapted to be placed between plate 42 and the adjacent surface of jaw member 32 and is gripped by suitable teeth 44 mounted in opposed relation on the facing surfaces of plate 42 and jaw 32, teeth 44 being retained in position by bolts 46.
In use, the ends of a suitable object such as an automobile door are inserted between plate 42 and jaw 32, the teeth 44 or the ends thereof gripping the outer extre'mities of door I2. Bolts 38- are then rotated to insure non-slip engagement with the door while the stretching operation takes place. When crank 26 is rotated, screw 24 travels in bushing is until steel shaft 28, extending therefrom, abuts plug 22 or housing [6. Continued r tation of. crank 26 in'the same direction, produces further separation of the housing members with the attendant stretching longitudinally of door member I2. Plug 22 absorbs the pressure on shaft 28 by screw 24 and the bent portions of the door are then readily hammered straight.
When door 12 is to be released, rotation of crank 28 is reversed, and the door is released from engagement by plate 52 and member 32. One of the clamps 30, preferably the one on housing I4, is slidably adjusted to accommodate different sizes of objects to be straightened.
While a preferred embodiment of the invention has been shown and described, it is to be understood that various changes in size, shape and arrangement of parts may be made without departing from the spirit of the invention or the scope of the appended claims.
