SWAGE OR DOLLY BLOCK.
Application led January 3,1922. Serial No. 526,754.
To all whom t may concern.'
Be it known that l, JOHN J. lVALKown, a citizen of the United States, residing at De-v troit, in the countyk of Wayne and State of Michigan, have invented certain new and useful Improvements in clivage or Dolly Blocks, of which the following' is a specification. y
My invention relatesv to swage or dolly blocks used for' bending' or straightening sheet metal articles in general but more particularly for use in connectionwithautomobile work for removing dents and bumps on hoods, radiator casings, fenders, etc.
One object of my inventionv is tol provide such a dollyblock combining a considerable number vof different shaped sides and edges, in order to make it useful for correcting fiat as well as bent surfaces and straight as well as curved edges. The dolly block is intended to be held against one side of the work with the portion thereof that coincides with the shapetowhich the plate has to be finished, and a hammer is used to apply light blows on the other side of the work.
Another object of the invention is to construct the device in a convenient size so that it maybe comfortably held in one hand, while using a hammer with the other hand.
In the accompanying drawingthe dolly block is illustrated in approximiately full size, `and Figure 1 shows a top plan view thereof;
Figure 2 a front elevation of Figure 1; and
Figure 3 a cross section along lines 3 3 of Figure 2;
This block` which is preferably solid and made of hard wood or metal has a fiat bottom 1() and one fiat side 11 forming right angles with the bottom and a sharp corner therewith as at 12. The top 13 is convex or turtle shaped and joins the flat side 11 with a sharp edge 141, see .Figure 3, while at the opposite side and front and rear ends it is curved so as to join the bottom with a sharp edge 15 at the right hand end, 'see Figure 2, an elliptical.. curve 16 blendlng with the bottom and running' tangentially therewith at the other end of the block.
The two ends together with the remaining side of the contour, as seen in horizontal projection in Figure 1, is formed of curved and straight lines which terminates large radius commencing at the point 17 and i at 19 running tangentically into va smaller curve to point 20, whereitforins a straight' line Vto point 21 then turns into a circular arc of smaller radius to 22 and finally terminates with a fairly rlarge arc up to point 1 8. The side having this compound contourruns into the bottom of the block and forms a sharp edge 24 therewith 20, whereas between 17 and 2O nofedge 'is formed butthe side is. curved yinto thebottom as already described. Between points 18 and 22 and for about half an inch up on this end to line 23 in Figure 2the side is flat between lines 15 and 23.
It willnow be evidentthat the flat side 11 has a sharp edge all around it.
In order to forma 900 edge in a plate, the dolly block should be held in onevhand and the edge 12 pressed against the plate where the right angle edge is to be formed, while blows are delivered from a hammer on the other side ofthe plate until the edge is gradually formed. Similarly if a rounded bead is to be formed in a plate, the rounded edgel is vheld under the plateand, accord ing to whether the curvature in the longitudinal direction should be short or long, the proper portion, as between 19 and 20 or between 17 and 19, is selected to press against the plate, while blows are delivered on the other side thereof.
To take out dent-s in a plate, if it has a narrow surface, the flat side l1 is pressed against it or if it is a wider surface the bottom side 10 is pressed thereto and blows similarly delivered on the opposite side of the plate. F or large dents and bumps on curved surfaces, the top portion 18 of the dollv block is used.-
aving thus described the invention what is claimed as new is:
1. A dolly block having a convex top, a fiat bottom, and a at side forming a straight edge therewith, the opposite side and both ends emerging in horizontal projection into la contour composed of one straight and several curved lines.
2. A dolly block having a convex top, a fiat bottom, and a flat side forming a straight between points 18 and edge therewith; the opposite side and both ends merging in horizontal projection into a contour composed of rone straight and several curved lines, the angle between said bottom and flat-side being 90.
3. A dolly block having a convex top, tiatvr bottom, a flat side forming a straight edge therewith and the opposite side running parallel with said flat side, and curved ends merging with said opposite side, the edges otl said flat side all being sharp.
4e. A dolly'blocl'havinga convex top, a ilat bottom and a flat side forming a straight edge therewith and the opposite side and both ends nierginginhorizontal projection into a contour composed of one straight. `and several curved lines, the straight part ot saidc-ontour being shorter than said Vflat side and running parallel therewith;
5.' Ado-lly bloelrhaving alconvexV top, a
latbottoin, and a flat sideft'orminga straight edge therewitlrandthe opposite siderand both endsmerging in horizontal into a con-` tour composed of one straight and several curvedlines,`the straight 'pa-rt of said contour` being. shorter .than saidl Y[iat .side and runningparallel therewith and the. curved endsrof the contour forming respectively acute and obtuse angles-'with said flat side,
said ends from said obtuse angle to the remote end ot said straight opposite side.
7. A dolly block having a convex top, a ilat bottom, a fiat side forming a straight edge therewith, vthe opposite side being straight' in horizontal projection, curved ends merging with said straight side, said straight opposite side being shorter than said hat side and running parallel therewith, the curved ends forming respectively acute and obtuse angles with said fiat side, a sharp edge being formed with said bottom'along said opposite side and one 'ot said ends from said obtuse angle tothe remote endfot said straight opposite side, and the remaining oneot said ends being curved to lblend smoothly into'saidftopand bottom inperypendieularv planes of the latter.
8. A dolly bloclrhaving aconvex top, a hat bottom, a flat side yforming astraight edge therewith, the yopposite side .being straightin horizont-al ,projectiom curved ends merging with said straight side, the angle between said bottom and said iiat side being 90o, the edges of sa-idftlat side all'be ing sharp, said straight opposite sidebeing Vshorter than said flat sideand runningparallel therewith andthe curvedends tormf ing respectively acute and `obtusey angles with said vflat side, a sharp edge being formed with said bottom along said .opposite side and one ot said endsv Jfrom saidobtuse angle to and including said `straight. opposite side, and the remainingone of said-ends being (-urved to blend smoothly intosaid'top and bottom in perpendicular planes of the latter. y f
