I I 31e/7625 6.' 7255226 BY Q M,% VQQ Patented Mar. 11, 1952 UNITED STATES PATENT FFICE SCISSOR TYPE ELEMENT FR REMOVING DENTS FROM BODY AND FENDER PANELS Francis G. Forster, Ecorse, Mich.
Application April 12, 1948, Serial No. 20,414
(Cl. 153-39) v 2 claims.
Thisinvention relates to metal working tools,
and particularly to a tool for drawing out and straightening panels when disposed adjacent to each other.
-Various means have been provided heretofore in the art for drawing and straightening panels,. such as those of automobile bodies when de# pivoted arms, the unpivoted ends of which are disposed in close adjacent relationship to each other and capable of being spread apart by power means applied between the two arms for forcing one panel outwardly from another. The arms are so constructed as to permit the use of stand? Accordingly, the main objects of the invention are: to provide a pair of arms pivoted at one end, with means for supporting a pressure applying element therebetween for moving the unpivoted ends apart; to provide a pair of pivoted arms with an abutment for a pressure applying device spaced from the pivot to provide a moment arm capable of moving the unpivoted ends of the arms apart for performing work on a panel to be straightened when force is applied thereto; and, in general, to provide a pair of pivoted arms for straightening panels which is simple in construction and economical of manufacture.
Other objects and features of novelty of the invention will be specifically pointed out or will become apparent when referring, for a better understandingV of the invention, to the following description, taken in conjunction with the accompanying drawing, wherein:
Figure 1 is a View in elevation of a device for straightening panels embodying features of this invention;
Fig. 2 is a plan view of the structure illustrated in Fig. 1; and
Fig. 3 is a view of structure, similar to that illustrated in Fig. 1, showing a modified form thereof.
Referring to Figs. 1 and 2, a panel straightening device ID of the present invention is illustrated, embodying an arm II made of two parallel side bars I2 and I3, the working performing ends 2 of which taper toward each other at I4 where they are connected by a threaded nut orboss I5. The arms are connected centrally of the ends by a plate I 5 and at the end opposite from that con--4 nected by the nut I5 by a cross bar I'l welded thereto. 'The bar il has an element I8 welded or otherwise secured thereto, having a head VI9 for a purpose which will be explained hereinafter.
A second arm 2l is made of Ytwo parallel sideA bars 22 and y23 which nest within the bars I2 and i3. along the parailel portion and which areA tapered at 24 to nest within the tapered portion I4 of the bars I2 and I3. The arms are inter` connected at the tapered ends by threaded nuts or'bosses 25 adjacent to the middle 'portion by abar 23 having a boss 2l thereonv containing an aperture 28 and at the opposite ends by a bar 29. A bolt 3l extends through the arms at a point remote from the head I9 so that the distance between the head I 9 and the bolt 3l provides a moment arm for a pressure element 32 which applies a force between the head I9 and boss I1. This forces the free ends of the arms II and 2| away from each other.
The element 32 is of conventional form, embodying a cylinder 33 having an aperture 34 in the end which extends over the head I9 and having a piston 35 projectable from the opposite end and having a stud 36 thereon which projects within the aperture 28. The device 32 is retained in position by the engagement of the head I9 in the aperture 34 and the engagement of the stud 36 in the aperture 28. Any means may be provided for applying a fluid to the cylinder 33, a hand-operated pump 31 being herein illustrated as being connected to the cylinder by the fiexible conduit 38.
Universally movable heads 39 have a ball and socket connection with a stud 4I and are threaded into the threaded apertures in the nuts or bosses I5 and 25. A plate 42, having a stud 43 therein, may be threaded into the head 39 to enlarge the surface thereof when it is desired that a larger surface than that of the head be employed for pushing out the panel to prevent it from being further distorted. The arms, when in collapsed position, have the heads 39 on the unpivoted ends disposed in close relation to each other so as to fit into a narrow space. When using the device, the head 39 is inserted between the panel to be pressed out and an adjacent panel, brace or other rigid element, and pressure is then applied to the device through the introduction of iiuid pressure into the cylinder 33 to force the head 39 on one 3 arm outwardly of the other to move the distorted panel outwardly to its original position.
A further form of the invention is illustrated in Fig. 3 which is somewhat similar to that illustrated in Figs. 1 and 2, with the exception that the pressure applying means is disposed beyond the length of the arms Il and 2l instead of therebetween as described. One arm 45 is made up of two` side plates 46, interconnected by suitable bracing elements 41 and 48, the latter of which is provided with a head 49 for receiving the apertured end of the device 32. The forward end of the plates 46 taper toward each other to engage a threaded nut or boss 5l which is welded to. be understood that the plates 42' may be applied to the head 39, the same as'on the head or heads 39 of the device illustrated in Fig. 2.
A bolt 6| extends through the plates 46 and 53remote from the aperture 51 so as to provide a lever arm equal to the distance between the bolt and aperture. The device is operated in the same marmer4 as that described for the device i1 lustrated in Figs. 1 and 2, the arm 52 being collapsed against the arm 5|` withthe heads 39 disposed adjacent to each other so as to be insertablefin a narrow space between a distorted panelA and a rigid element against which pressure may bel applied to move thev panel outwardly to its original position. This is accomplished by applying uid pressure to the cylinder 33 for moving the piston. 35 outwardly to cause the arm 52 to` move outwardly from the arm 45.
The nuts or bosses 5| and 59. receive the threaded studs 4| for supporting the.kv heads 39 for universal movement thereon. It is;
What is claimed is:
1. In a device for pushing and straightening panels, a pair of channel-shaped arms of substantial depth near one end, a pivot for securing the two arms together at said end near one edge thereof, anchoring means on one arm at said end near the other edge thereof, and anchoring means on the other arm remote from said end of greater depth, said anchoring means being disposed to receive a pressure applying device for applying a force longitudinally of said arms for moving the unpivoted ends of the arms outward- 1y relative to each other substantially at right angles to the direction of said applied force.
2. In a device for pushing and straightening panels, a pair of channel-shaped arms of substantial depth near one end, a pivot for securing the two arms together at said end near one edge thereof, anchoring means on one arm at said end near the other edge thereof, anchoring means on the other arm remote from said end of' greeaterdepth, said anchoring meansbeing disposed to receive a pressure applying device for applying a force longitudinally ofv said arms for moving the unpivoted ends of the arms outwardly relative to each other substantially at right angles to the direction of said applied force, and universally mounted plates secured to the unpivoted ends of said arms.
