3 Claims. (Cl. 29-89) This invention relates to work holding device, and more particularly deals with a novel device adapted to hold automobile fenders and the like in divers positions to facilitate work thereon.

It is well known that fenders or mudguards, radiator shells, engine hoods and other parts of automobile bodies are often bent out of shape due to collision or other accidents, and hitherto it has been diicult to repair them. On the one hand, if repairs were made without removing the damaged part from the body, the work often did not prove satisfactory; and on the other hand, if the part was removed from the body in order to repair it, it was difficult to handle and maintain in proper position, with the result that it took an unreasonably long time to make repairs and a helper was generally needed to hold the work in position.

My improved device .enables the mechanic to do better and faster work and makes unnecessary the use of a helper to assist in holding the work in proper position. These and other objects of my invention, as will appear hereinafter, result from the novel details of construction and arrangement of parts described and illustrated in the following specication and annexed drawings, in which- Fig. 1 is a front elevational view of my work holding device;

Fig. 2 is a front elevational View of the central adjustable work holding means thereof;

Fig. 3 is a cross sectional view along line 3-3 of Fig. 2;

Fig. 4 is a sectional view along line 4-4 of Fig. 1;

Fig. 5 is a front elevational view of the adjustable work holding means at either end of my work holding device;

Fig. 6 is a side elevational View of one of the adjustable arms of the work holding means of Fig. 5;

Fig. 7 is a side elevational View along line 'i-'I of Fig. 1.

Referring now to the drawings, and particularly to Fig. 1, I is a base supporting a member II telescopically associated with a tubular member I2, which associated members are held positioned with respect to each other by bolt I3 and are adapted to increase or decrease the height ofthe work holding device.

Tubular member I2 is associated at its upper end with a forked member I4 and swingably positioned with relation thereto by means of bolts I and I6. As more particularly shown on Fig. 7 a segmental member I1 provided with a plurality of apertures I8 is held in fixed relationship to forked member I4 by bolt I5 and adjustably positioned with respect to tubular member I2 by bolt I6, thereby permitting my work holding device horizontally to swing over an arc of substantially by removing bolt I6, swinging member I4 to the desired angle, usingV bolt I5 as pivot and replacing boltvIS. It will be understood that the degree of adjustability will depend on the number of apertures I8 on the segmental member I'I (the greater the number, the finer the adjustment) and that a still greater degree of adjustability may be obtained.

f' moving bolt 23, swingingv member 22 to the desired angle using bolt 2| as pivot, and replacing bolt 23. It will be understood, of course, that the degree of adjustability permitted by segmental member IS depends on the same factors hereinbefore stated with respect to segmental member Il. v

Tubular member 22 has attached at right angle thereto (as by welding) a horizontally dis,- posed tubular member 23 having telescopically associated therewith a member 24, which associated members are held positioned with respect to each other by bolt 25, said member 24 being provided with hanger 26 and bolt 2l, said bolt 2l serving as pivot for member 28.

Member 24 is -also provided near its free end with a slotted member 29 adjustably mounted on said member 24 by bolt 30 and segmental member 3I. Member 29 is provided at its upper end with a segmental member 32 held positioned with respect to member 29 by pivot 33 and bolt 34, said member 32 being horizontally swingable with respect to the axis of member 29 over an arc of substantially 180 described by slot 35.

segmental member 32 carries a plurality of mem- Y bers 36 adjustably mounted thereon as will be more fully described hereinafter when referring to Fig. 5.

Tubular member 23 has attached at right angle thereto a horizontally disposed member 3l (see Fig. 4) having telescopically associated therewith l tached'` to member 48 by. bolt Gil.

and being held adjustably positioned with respect l to member 44 by bolt 47. Members 44 and 45 are adapted to co-act in association with pivot i6-and bolt 4l for the purpose of gripping and holding the edge of a mudguard or the like being held positioned for the purpose of Workingon'it.

Referring again to Fig. 1, member 22 has attached thereto (as by welding or screwing) an elbow 4.8A provided with a horizontally disposed member 4s. Said member 4,9 is provided near its free end with a slotted member 25, adjustably mounted thereon by a bolt and segmental member 3 l Member 29, is provided at its upper end'wth a segmental member 32 held positioned with respect to. member 29 by pivot 33' a-nd bolt 3d','said, member 32 being horizontally swingable with respect to the axis of member 29." over an arc of substantially 185).o described by slot 3 5. segmental member 32' carries a plurality ot members 36. adjustably mounted thereon as will be more fully ydescribed hereinafter when referring to Fig. 5. i

It will be readily understood, of course, that elements 29.', 3d', 3i', 31', 33', 34', 35." and.3.6, are substantial duplicatesv of

elements

29, 30, El, 32, 33, 34, and .'ihereinbefore described.

Referring new toV Fig. 5, slot 48. is adapted for longitudinal adjustment of. member E-Sby means of bolt 3rd. Slot V4l1is. adapted to permit member 32 horizontally to. swing Ywith respect to the axis of-member 2,9. Slot is adapted to permit member. 3,6 horizontally tov swing with respect tothe axis thereof. Bolt.` 34 is adapted to hold member 31. in adjustableI relationship with member 2.9; Bolt 5l. is. adapted to hold member 36 in adjusts able` relationship. with member 32. Slot 52 is adapted for. longitudinal adjustment of member 35, and bolt 53 isadapted toA hold the desiredlposi.- tion. Pivot 54 is for the purpose of holding. mem.- ber \3.3 in swingable relationship. with member 32. Angle, 5.5. isr provided with a slot 55. andL bolt4 51: adaptedV to regulate its position` longitudinally, and is alsoprovidedwith an aperture. 5.8!through which. is passedA a bolt, (not shown) adapted to engage theA tapped` edge. of a mudguard or. the likefor the purpose of'securely bolting it in place, so that it may be positioned while beingrepaired;

Referring again to. Fig, 1, 59 isa platform at- Adjustably mounted on said platform is a frame 6|` held thereon by bolt 52.

Referring now to-Fig. 2, d3 are a plurality of pivot supports on which are mounted pivots 64. Pivoted thereonare a pluralityvofY tubular members. 65 telescopioally associated with members 6B, said associated members being adjustably positioned with respect to each other by. bolt 6.1.

Frame` di. is provided with stops 63. adapted to limit the horizontal movement of members within the limits shown in broken lines. Members GS areprovded with angle heads B9, said angle heads. having slots 'lill and bolts 'H adapted to regulate its position longitudinally, said heads also bei-ng provided with apertures 12 adapted to engage the tapped edge of a mudguard or the like for the purpose of securely bolting it in place, so that it may be positioned while being repaired. The construction and arrangement of parts of these pivoted adjustable elements is more particularly shown in Fig. 3.

Referring again to Fig. 1, member 28 is provided with an adjustable gripping head 13 substantially as shown on member 42 in Fig. 4, and its shank is provided with a plurality of apertures 'F4 for the purpose of adjusting its length. This member serves the purpose of gripping an untapped edge of a mudguard or the like for the purpose of bracing it and thereby permits proper positioning thereof while undergoing repairs.

As will be readily understood from the foregoing description and annexed drawings, the work holding device of my 1nvention is characterized by extreme flexibility of adjustment, and is thereby a valuable tool easily arranged for work and nevertheless olf, simple construction. In operation, the supporting members having tapped heads are bolted to the tapped (body) edge of the mudguard, for instance, and those having clawlike heads, are used: to grip the untrapped (outer) edge. Members l1 and i9, because of the unie versal; adjustment they permit, make it possible for the mechanicoj` operator to. position the work in the most favorable manner to, carry out the repairs. i

It will be understood that my invention lends itself to various modications within the scope thereof. I have described and illustrated` preferred embodiments of my invention, but it should be understoodthat I do not. intend to restrict myself to the particular details of' construction and arrangement of parts herein described and illustrated except as limited by the scope of the appended claims.
