Dec. 21, 1948. A. R. CHEEK ENGINE HEAD LIFT ING TOOL Filed Oct. 23, 1946 INVENTOR. C H E E K ALVIAH R BY Patented Dec. 21, 1948 f UNITED. STATES ENT OF FICE '1 I I 235E917 ENGINEIH'EAD :LIFTING' 'roor; Alvah RI. ohek; Thurman; Idwa Application octoteiasjism, sesame-705mm s'ciaimsf (oi; 294 -1 5y This invention relates 1 a cylinder headlift ing tooland more particularly to a tool for lifting the cylinder headsof engin'es ofthe" valve-in head typeysuch as of the engines used" at present in Buick' m'otor' car's.

It 'is"l"an "object of this invention to provide a" cylinder head lifting'tool which is simple'and inexpensive in nature and 'can' be attach'edto the cylinderhea'd to beremoved 'fr'om itscylinder block in a simple and rapid manner. I l

It is a further object of the invention to 'pro'-" vide a cylinder 'head liftingtoofwhich"can be attached to the cylinder head with the "aid of such" fastening means only as'are present'on th'e'cylin der head anyhow. I

It is another object of the invention to provide" a cylinder head lifting toolinthe' form "of a rectangular frame which has'a central portion that serves as a carrying handle and'which' can" be rigidly spaced from the top surface'of the cylinderhead.

Still another object of the invention resides'inthe provision of a cylinder head lifting tool com? prising a rectangular =frame whose'length is *ad; justable ma symmetrical manner relative to-the aforementioned "central carrying handle so that the weight of thecylinder head remains sym-i metrically distributed relative tosa'id carrying? handle regardless to what length of cylinder head the tool hasto be adjusted. v I

Still anotherobject of the inventionis the pro vision of'a cylinder head lifting tool comprising'a frame composed of'a rectangular frame which; while adjustable at least in the longitudina'ldirec tion, is rigid when so adjusted and tWQ links which can be tightly fastened toone ofthetwo: longitudinal sides of said rectangular frame'and'; to one side.;of the cylinder 'head to format rigid support for the cylinder head also when the frame is used to serve as a stand for the cylinder head in upside-down position. When the tool is removed from the cylinder head these links may be folded down upon said frame so that they-do not protrude beyond. the height of the latter.

Other objects of theinvention will appearas the description proceedsyreference beinghad to the accompanying drawing,in which- Fig. 1 is a perspective view of a cylinder head lifting tool accordingto the invention, showing this tool attached -to a cylinder head belonging to a motor car engine of the valve-in-head'type';

Fig; 2 shows the arrangement of Fig? l'ina side elevational view;

Fig -3 shows in a perspective view the cylinder head lifting tool of Fig. 1 in upside-downposition;

wherein thetool' serves 'as'asupport'or standfor' the cylinder head; and I 4 Fig. 4 is aplan vi'ew,"at a slightly reduced scale,

1 to 3 the lifting" tool is shown attached'to the cylind'erh'e'ad, this tool consisting basically of a rectangular'framed I, two linkslZ'ahd l3, and a central handle member l4.

Therectangular frame ll is'compose'd of six r.parts',".namely two T-shaped' elements M", M,

forming-together an H-shaped central member l4, an'dgfour'L-sha'ped members I5, l6, l7 and I8. The members i5and l6 form together'a U-shaped' frame portion which is slideably mounted on the legs 19 and '20 of the H-shapecl central v, member l4, whereas the two other L- shapccl members I! and 18 form together another U-shaped frame portion which is slideably mounted on the legs 2| and "22 ofthe H-shapedt centralmembe'r l4. Set

screws

23, 24, 25 and 26 serve to secure the U-shapedframe portions on the central member 14. When" the set screws 23' to 26 are loosened theltw'o Ur-shaped frame por tions of the frame II, can be shifted lengthwise ,on the legs l9 to 22 of the H-shaped central mem her ill for, adjusting 'the frame to any desired length; whereupon said setscrews are tightened to keep the frame at the chosen length. It will be seen tlrat the two u-shapeddrame portions are adjustable relative to'the central member l4 independently of one another, and that regardless of the length of the frame to be used theyalways can be adjusted so as'to extend symmetrically relative'to the'central member It,

The frame ll isialso adjustable in thetrans verse'direction. Forthis purpose one 1eg'21 of the L-shaped member IB'fits slideably into a tubular leg 29 of the'L sh'aped member 15, whereas a leg 28 of the'member l8 slideably fits into a tubular leg-3001 the member I! and'leg" l at the adjusted width.

3f of the T shaped'element l4" slideably fits into the 1eg'3l' of'the other T'-sh'aped element M of thecentral member l4. Set screws 32, 33 and 34s are provided for keepingthe frame ll Figi4 shows in-ruu'nnes the frame as adjusted'to its'snial'lestsize 'iri'th-e longitudinal direction as well' as 'in"thetransvr'erse direction; whereas it shows in d'ot' andda'sli line's ma ame" adjusted 'to'a' larger size "'inthej lo'ngiti'idinal as the passage of stud bolts 36- which in the type of cylinder head shown are part not of the tool but of the cylinder head and extend out from the top thereof. Nuts 31 which are also part of 4 work on the cylinder head, e. g. on the valve seats. is to be performed, the tool together with the cylinder head is turned upside-down into the position shown in Fig. 3 in which position the tool forms a rigid stand for the cylinder head while work is done upon the latter.

When it is desired to place the cylinder head back upon the cylinder block, the cylinder head together with the tool is turned back into the position of Fig. l, the handle I 4 is grasped and the cylinderhead is carried by means of thetool to thecylinder block and properly positioned there- 'on'.-'-Then, the nuts 31 and screws 4! are taken the car engine are screwed on the top end of the stud bolts 36 to limit movement of the frame ll away from the cylinder head.

While the 1 slots are arranged :inthe one longitudinal side of the frame lLthe links l2 and i3 are fastened at one end to the other.-

longitudinal side of the frame by meansof screws 38 passing each through a hole 39 in the frame members It and i8. There are several holes 89 provided in the frame for each link I2 and I3,- five such holes 39 being shown for each link in secured to the side of the motor. may be chosen In the example by selecting two of the screw holes present in the manifold base usually found on conventional engine heads. The screws ll are screws which on the cylinder head are ordinarily used to fasten the manifold. The length of the links I2 and I3 is conveniently chosen so that when these links .are attached to the engine head and the'frame in the manner shown in full lines in Figs. 1' to-'3, that is to say, the screws 4! are passed-through the lowermost of the holes '40 in the links I2, I3

and the screws 38 through the outermost of the holes 39 in the frame II, with the length of the frame being adjusted so that the links l2 and [3 are in a vertical position, even the longest studbolts 36 used on conventional machines will extend above the frame il substantially only for the length which is necessary to take the'nuts 31. For shorter stud bolts 36 the active height of the links I 2, l3 can be reduced by passing the screws through another of the holes 40 and by using to the other of said two longitudinal sides of said vided atthe free endof each linkforthe attach I ment-of the'latter to theside of the'cylin'derli'ead the links l2, I3 in an inclined position such as indicated in an exemplifying manner in dot and dash lines in Fig. 2.
