May 9, 1933. D. P. MURPHY VALVE SERVICE RACK Filed July 29, 1932- Patented May 9, 1933 UNITED STA res rArNr VALVE SERVICE RACK Application led July 29,

My invention relates to novel and effective means to facilitate the operation of reco`n ditioning the valves of an engine and more particularly to racks for holding the engine 5 parts removed incidental to the operation and the materials used in theoperation conveniently in a position to facilitate the operation.

It is a Well recognized fact that in the op- 10 eration of valve grinding, more effective and satisfactory results are secured in a shorter time with less expense if the valves are kept free from foreign matter and in such order that they may bevreplaced in the same valve seats from which they Were removed With the expenditure of no Yother eort than that-re quired to partially disassemble the engine,- grind the valves and replace the parts.

Heretofore it has been almostimpossible for a mechanic to keep the valves in proper order, free from grit and foreign matter and conveniently separated due to the fact that no satisfactory means of holding the parts and materials incidental to the grindingop* eration has been provided Which Will be convenient to handle and mount upon the engine Y in an accessible position, which may bea part ofthe engine exposed incidental to the operation and Which Will stay in position Without the necessity of providing some special means for holding or securing the same in position.

A common device for this purpose Which mechanics have heretofore resorted to Without much satisfaction or success is a stick of Wood with a series of holes drilled therein or some such other contrivance for receiving the stems of the valves. However, these more or less make-shift devices have not proven '1 satisfactory for the reason that they provide no means of readilyfsecuring the device to any part of the car or motor in a convenient position with the result that they are continually being knocked onto the floor With r the result that the valves Will come in contact With foreign matter and may drop out or become damaged due to contact With the Vfloor surface or tools. w

Another difficulty often encountered in grinding the valves of an internal .combus- 1932. Serial No. 626,245.

tion engine is the loss of some ofthe parts removed from the engine incidental to the grinding operation such as valve keys or pins since they are usually left lying around on any Hat surface `which must be used'in the 5,5 absence of proper holding means.

Vith the above mentioned and other. difficulties and annoyancesv incidental to the Operation of grinding the valves o-f'an engine, it is a primary object ofthe present inven- 60 tion to provide a rack for holding the valvesy i in consecutive order which' may readily be mounted securely upon the engine' block itself, if desired Without the use of any special securing means Whatever. s

Another object of thel invention is to provide a `rack which Will be compact in conv .struction so as not to interfere With the movements of the mechanic in Working on the motor.

Still another object of the invention is to provide a rack Which Will hold a large number of valves and Which Will provide means for holding the valve keys and pins When they are removed. ,i775

A further object of the invention is to pros Y vide in said rack a receptacle for holding the valvevgrinding compound used in the grinding operation and which must usually be left lying around in a small can. 39

A still .further object of the invention is to'provide all of these features in a rack which is highly eifective,extremely simple in construction, cheap to manufacture and Which may be produced ata very loW cost. y

:Other objects and advantages of the invention Willbecome apparentY during the course of the following detailed description of the invention when read in conjunction With th-e accompanying drawing, Which forms 90 a part of this specification and in *Which Y i Figure l is a perspective view of a preferred embodiment of the invention, and

Figure 2 is a central vertical sectional vieW thereof. y f5 Referring now more particularly to the n drawing, wherein like numerals refer to like parts throughout the sam-e, l0 indicates the valve rack which is preferably formed from a single block of Wood although it could read- 1GO ily be formed from metal if desired. The rack comprises a substantially circular base portion 11, preferably several inches in height and which terminates in an inclined ledge 12 extending entirely therearound. The circular ledge 12 is terminated inwardly by a head or upper body portion 13 which is formed integral with the base or lower body portion but considerably less in circumference. This head portion has the sides thereof tapered outwardly from the juncture with the ledge 12 as at 14, and is formed on the circular edge of its upper face with an inclined ledge 15, which is of lesser inclination than the ledge 12. The flat top 16 of the head portion 13 is formed with a depression 17 in which is mounted a can 18 for holding valve grinding compound or the like.y

A series of sockets or holes 19are drilled into the base portion 11, said sockets opening` on the ledge 12and being disposed at such an inclination to the vertical that their axes are at approximately right angles to said ledge. Another series of sockets or holes 20 are 'drilled into the head portion 13, said sockets opening upon the ledge 15 and also having their axes approximately at right angles to said ledge.

It will thus be seen that the holes 2() more n-early approach the vertical than the holes 19 so that when the stems of valves are seated therein, the heads of the valves in the base sockets will clear the stems of the valves in i the head sockets.

The sockets will be numbered in consecutive order, in the embodiment shown, the head sockets being numbered from 1 to 10 and the base sockets from 11 to 24 so that this rack will accommodate the valves of any engine,

open end of the sockets which receive the valve stems, thus Afacilitating the positioning of the valves therein and also dispose the indicia placed thereon to identify the sockets by number at such an angle as to be conveniently read.

For the purpose of holding the valve keys which are so often temporarily lost or misplaced, I provide a draw-er 21 in the base of the rack, sai-d drawer preferably running entirely through from one side to the other so that it can be opened from either end thereof.

In order to provide for securely mounting the rack on the engine block 22, holes -23 are drilled in the bottom of the base to fit 'over the stud bolts 24 commonly carried by the motor block which are exposed incidental to the grinding operation. In the form of the invention shown the holes 23 are shown as being preferably spaced to t over two spaced studs but in case the'spacing of the studs varies, the rack can be held just as satisfact-orily on one stud.

For convenience in handling the rack when it is desired to carry the valves to a refacing lathe or to move the rack for any purpose, a bail handle 25 is provided, having the ends thereof pivot-ally secured in suitable ,openings on opposite sides of the head portion 13.

It will be noted that due to the angular setting of the holes 20, the valve heads will be disposed a suficient distance from the can 18 to permit ready access thereto to reach the grinding compound therein.

-From the foregoing description, it will be readily apparent that I have providedan extremely simple effective and inexpensive valve rack which will greatly facilitate the open ation of grinding motor valves and which overcomes'the difficulties theretofore encountered in the use ofk other'devices which have failed to accomplish the purpose for which they were designed. f

While -a preferred embodiment of the Vinvention has been shown and described, it will be understood that variousV modifications in the details of construction and in the selection of materials may be resorted to without departing from the spirit of the invention as definedin the appendedl claims.- "l
