UTILITY DEVICE Filed Feb. lO, 1930 Patented Mar. 15, 1932 l ERNEST BERNITZ, JR., OF LA MESA, CALIFORNIA UTILITY DEVICE` Application filed l1 `e`bruary 10, 1930. Serial No. 427,404. l

My `invention relates to utility devices and particularly to such devices the use of which areassociated with the reconditioning of motor or cylinder heads and the like, a particular object being in providing a convenient means for supporting in an adjustable manner cylinder heads during the process of grinding valves, reconditioning'valve seats and removing valve springs and pins. j It is purposely intended for use with shop equipment in automobile repairing. In some instances where the rocker arm is not removed from the cylinder head a special auxiliary attachment is used. While not being used the attachment is advanced to a. forward position so as not to vinterfere with the operation of the remaining equipment.

Fig. 12 is a perspective view showing an alternate construction of the adjustable compresser toolV fulcrum.

Referring in detail tothe drawings, the invention comprises a main supporting frame composed of a base plate 1 containing screw or bolts holes `a, and two end frames 2, which are of like construction, adjustable thereupon. Said end frames 2 contain a slotted hole 3 atone end through which is shownextended an inter-connecting rod 5 running athwart the frame. Said inter-connecting rod 5 isadjustable within the slotted holes 3 and .has an anchor rod nut 6 on the inside 'of the end frames, and an anchor rod wing nut 7 on the outside of the end frames for rigidly holding the aforementioned inter-connecting rod in position, as well as bracing the end frames 2. t j

There is similarly located, and adjustable as to width, a second rod 8 inter-connecting theend frame 2,. AIt likewise has an anchor nut 9 bearing on the inside of the end frames and an anchor wing nut 10 bearing on the outside of the end frames, and serving a purpose similar to that of the anchor rod 5. l

To the anchor rod 8is rotatively fastened a pair of straps 11 containing slotted holes-14 anda loop hole l5. Said` straps, in turn, being adapted to be fastened to a `detachable motor head 16 by means of a bolt 12 and a wing nut 13'. The straps 11 are shown in Fig. 11. i' .Y f

There :are two distinct positions of the motor head shown in the drawings-one in Fig. 1 when the component parts are assembled, another in Fig. 3 Where the)T are disassembled. In Fig. 1 is noted means for dismantling the motor head preliminary to re-conditioning it, while in Fig. 3 the component parts. are removed as they will beto enable a mechanic better .to perform his work. In this-view the motor head is also shown plac( d in a position that will properly afford access for performing the re-conditioning work.

The loops l5 permit the straps 11 to slide upon the rods 8 whereby they may be made to accommodate the various sized motor heads.

There is similarly attached to the rod 8 a pair of supporting beams 2l, which are adapt ed to carry the weight of the motor head. Said attaching means consists ofan eye loop 2l@ through which is projected the rod 8', the free ends of the beams2L being in turn supported by the inter-connecting rod 5. These beams are. also slidable upon the rod? 3 for the same purpose. as that of the straps ll.

Said beams 21 are shown inl Figures l and 3 apart therefrom inl Fig., 7. The sectional view of the beams shown in Fig. 8 will now be described in conjunction with the view appearing in Fig. 7.

As aforementioned the supporting beams 2l are adjustable athwart the. frame so as to accommodate various sized'V cylinder heads upon the-anchor rods 5. and 8.

Tn detail theI beams 21 comprise a substantially channel shaped section having` a. pair of flanges 22, the web portion of which is ef;- tended" in a loop 21a, said loop providing an adjustable attachingv means for the beam upon the anchor rod. 8.1

The flanges 22 are out away at 23 to form al gap, and occupying a portion of said gap` is a ledge-supporting plate 25. The remaining portion ofthe gap formed' by cutting away the flanges 22 permits the flanges 29 and 30 f ofthe ledge, later to be described, to rest upon thesupporting plate 25. The. supporting plate 25, see 8, may be varied relatively in height. It isv supported u-pon a. thumb screw 25 extending through a threaded hole 24 and sustained in proper position by means of a wing nut 27.

When the cylinder head I6' rests upon the. faces ofthe flanges 22 ofthe beams 2l it will' be obvious that, in order that the valves in different depth compression. chambers may always rest upon the valve bolsters 32 it will be necessary to have an adjustable supporting means as outlined in the preceding paragraph.

ln Fig. 7 the plate 25 is shownY resting upon. the web portion ofthe beam'. Such position takes care ofthe most shallow compression chamber. Elevating plate'25 will cause' said holsters Co-take. care of any greater depth compression chamber.

The ledge hereinbef'ore' referred to is detachably supportedY in the gap 23. lt. comprises' a pair of angle supports 29 and 30 connected together by a splice plate` 3l riveted or welded to the angle members at 28. Slidably mounted upon said' angle* supports arey a pluralityv ofbol'sters 32' adapted for lsupporting the valveibod'ies 17.. Theyv are made of suliicentV thickness to` accommodate any depth compression' chamber and. are adjustable for more shallow conditions by operating wing nut 26 which in turn lowers or elevates plate 25.

By referring to Figs. fl, 5 and 6 a clear conception of the different parts composing its assembly may be had. Further reference to said views discloses a reduced portion 36 of the bolster 32 which rides Within the space between the

angles

29 and 30. A stove bolt 34 inter-connects the bolster 32 with the angle supports 29' and 31 by means of the nut 33 and the washer 35. lVhen the 'holsters 32 are placed on the cylinders they are so arranged as to accommodate both valve bodies and keep them from falling through.

The ledge is made of sufficient length to accommodate the longest type of cylinder head so that a sufficient amount may project therebeyond as shown in Fig. l so that that portionmay be grasped by thehands tomanually rotate the cylinder to the positionshown in. Fig.. This scheme insures the valve bodies from dropping out of the cylinder head. After the cylinder head is rotated in the latter position the ledge is detached until.` the reconditioning work is performed after which it is again placed infits former position` and the cylinder head is again man` uaily rotated in a position for the assembling.

of the component parts.

Cylinder heads range in size according to the number of cylinders. They are variable in length and breadth as well as height. The present invention: is universal inrespect to its adaptation for the different sizes. Means to accommodate cylinder heads of various lengths and breadths have been outlined.. A. means for accommodating those of variable thickness will now be outlined. Such a4 means is shown in Figures 1 and 3, Fig. 3 illustrating more clearly why adjustment is necessary, since a correct angle for the application of tools for re-conditioning makes the job easier and simpler.

Therefore upon further observation of the latter' view it will be seen the adjustment comprises a rest bar 72 to carry the inverted cylinder head.. lt is supported by a pair of levers 67 and 7l similar in construction eX- cept that lever 67 is provided with an adjusting stud 68. Said levers are keyed to a shaft 66 by means of a key 66a..

The adjusting stud 68 is provided with. a knurled hand wheel 69 having a handlev or knob 70 with which to operate the same. The end of the screw 68 rests upon the base l and by turning the stud will elevate or lower the rest bar 72 as described in the following` operation.

Afterv the cylinder head is swung outwardly shown. in Fig. 3 so as to rest uponl bar 72, in order to adjust the level thereof, for grinding valve seats and the like, handle 'ZO-is rotated and the stud resting on the base plates l elevates or lowers resty bar 72. by

il Ll levers 71 and 67. Said levers are keyed to shaft 66 at 66a, adjustment being carried back from handle through crank- 67 to shaft 66, it being keyed `on opposite sides will elevate or lowerlever 71 thereby adjusting rest bar 72 which will in'turn establish a correct position for re-conditioning the cylinder head.

In the re-assembly and disassembly of the component parts preparatory to re-conditioning the cylinder heads I employ the use of a compressor bar of unique construction to facilitate this part of the procedure.

Itis shown in operative position in Fig. 1, in inoperative position in Fig. 3 and separately shown in Fig. 9 with a section thereof appearing in Fig. 10.

The compressor bar consists of a left hand bar member 37 anda right hand bar member 38 which are joined together Aby a grip 52. At the opposite end from the grip and in each of the respective bar members are holes 53 which are adapted to contain a wrist pin 53a for pivotal movement thereabout. Said pin being j ournaled in 'a connecting link later to be described.

Upon the forward end of the compressor bar is mounted a stirrup 39 containing a recess for clearing the rocker arm when the rocker arms are in place. In Fig. 1 is illustrated the manner of 'removing the pin 18 from the valve 17.

Said stirrup further comprises' a pair of lips 4,1.and 42 flanged outwardly and inwardly from the sidesthereof to form 'a sliding guide on the bar members 37 and v38. It is adjustably joined to the compressor bar by uniting it with a U-shaped plate 43 by means of a tie bolt 44 to which is screwed a wing nut 45. f

As before mentioned, the use of this stirrup is limited to cylinder heads where-the rocker arms remain integral with the cylinder head, and when not in use can remain in the kposition shown in Fig. 9 without obstructing the use of the principal functioning members now to be described in conjunction with Figures 2, 9 and 10.

Valve springs as shown in Figures 1 and 2 are variable in diameter therefore a pair of adjustable clamping jaws 46 is essential to accommodate all conditions. They are oppositely opposed having a tapered front edge 50 extending outwardly from'a downwardly projecting guide lip 51 which limits the side motion of the spring washer, while the tapered edge portions 50 bear down on the top thereof. Said jaws are held in spaced relation on the top edge of the bar members 37 and 88 by inter-connecting them with a bottom strap 47 by means of a stud bolt 48 and a wing nut 49. The latter construction is clearly shown in Fig. 10.

The compressor bar is pivoted to swivell operate from a fulcrum link 56,. The fulcrum link is furthermorethreaded and a nut 54 provides adjustment in height 'for the compressor bar to make it adjustable for different height cylinder heads. The lower link portionl 54 is radially and slidably movable upon the inter-connecting rod 5.

The illustration of the different positions of the compressor bar shown-in Figures 1,-2 and 3 clearly sets forth its function inthe removal of valve pins. A brief operation consists of placing the cylinder head upon the frame as shown in Figure 1, over the valve support, compressor arm is rotated over valve springs, tapered jaws are made to engage valve washer as shown in Fig. 2 and finally by manually depressing the handle p 52 the valve pin 18 may beeasily removed.

Since certain types of automobile engines necessitate an arrangementwhere it is necessary'to use the stirrup member, and although these are being replaced until its use may be eliminated entirely, the use of this adjunct makes the device universal.

In Fig. 12 is shownan alternate supporting link 59 for the compressor bar. It differs from that shown in Fig. 1 by having a ratchet adjusting 58 which is engaged by a pawl 60 screwed to the knob Vportion 59 thereof by means of a screw 61. Ahole 65 in the lmob permits partial rotation of the same. The

upper terminals

62 and 63 of the link containing holes 64, and the lower terminals 54a and 54?) containing holes 5a are similar in construction to that shown in Fig. 1 and will not be described again. Such a modification is thought to come well within the scope of the appended claims.
