To all 'whom it may concern." i
Be it known that I, ARz'ENo J. DILLEY, of Muir, in the count of Ionia, in-theState of Michigan, have lnvented new and useful Improvements in GreaseGuns, of which the l following, taken in connection withthefaccompanyin drawings, is a full, clear-, 'and exact descrlptron.
This invention -relatesfto certain improve-V a eating purposes, and particularly as applied to the various bearings of-motor vehicles,l
is usually put upin cans A'or receptacles of convenient size for delivery to the user, and One of the objects ofl my presentinvention is to provide a pump which may be easily and quickly attachedto-the outlet of the can and used in connectionv therewith in lubricating bearings', thus permitting the Ypump to be used as-the relling medium fortransferring the greasedirectlyrromthecan to the bearing, and avoiding the inconvenience of separate meansV for filling of the pump.
Another object is toenable the valve-which controls the inletand outlet ports 'to be operated at will by the piston operatinghandle at the end of each stroke of the-piston so that the communication between the inlet and cylinder may be opened, and that be tween the outlet and cylinder closed lat the end of the compression stroke, while -communlcation between the outlet and cylinder is opened, and that between the inlet and cylinder is closed at the end of the suction stroke 'of the piston. l l
Other objects and uses relating to specific arts of the grease gun will be 'brought out 1n the ollowlng description. v
" In the drawings- Figure -'1' is'a side elevation, partly in I. section, and partially broken away, of a lu- -bricating apparatus, showing the various l f/eatures of Vluy-invention.
Fig. -2- is an enlarged sectional view through the lower portion of the pump and Y valve case, showing more particularly the Y coupling connection between the can and delivery pipe. Fig. 3
is an enlarged horizontal sec;
tional view taken Pl of `ig. is 'an enlarged transverse s e'ctional v1ew through the `:upper portionVVV of the pump cylinder taken the'plane of line Figs. -f and side elevations' partially insection of the same pump applied in different ways to the exterior and interior ofa grease-containing'pail. y y In Flg. -1- is shown an ordinary Agrease contalnmg can 1, arrangedn an inverted position and provided with an outlet --2- for connection with 'a piston pump 3-. ofY the reciprocatory typefthe base of the pump provided with anjL shaped plate '1-, having oneV end secured thereto 'in' a substantially horizontal positionand its other end deflected upwardly at '-4=to rform a rest for vthe can at avpoint some distance rom'the outlet v If Vdesired the `upper endof the pump cylinder may. be'provldedwith a tubular nipple 5- secured in 'an opening' inthe adjacent side of the can -'l-f to "connect the tinterior of the pump -eylinder'with'the interior of the can above the grease line, when'thecan 1s inverted,so thatV when the piston is elevated to draw the grease intothe bottom of the pump case a certain amount. of airpressure wlll beexertd from the top `of the grease bodyto force the latterdownwardly,
and thereby `assistiits passage into the pump. The pump comprises an upright cylinder -6-' anda reciprocatory piston movable therein', said piston beiuggprovided with a tubular' stem -8 '-,1extending-upwardly through a'gland"-'-;9.- onathe'upper end of the cylinder, and carrying; at -its external (ind a handle 10., shown more clearly'in i.-l. .v valve case-.lle-'is removably secured by` screw threads -to fthe lwer end of the c linden-6F, and is provided withan uprightvalve chamber coaxially and commumcatingwithfsaid cylinder for receiving a rota case
cup-shapedvalve 'said valve ing also providedzwithdiametrically -at its upwardjend and 'communicates with opposite mletf and outlet ports -14-' -15- leading from '-thegl valve chamber l with the ing and c osin commixnication. between said and the lnteriorof the valveand cylm er.
The valve 13% is provided with an upwardly projecting( stem 17 preferably of angular cross section, shown in Figs. -3-' ani 4hlooselyhfit in a corresponding s a e len wise -18- mythe tulbularstegnti '-8, so that when either stem is rotated similar motion willbe imparted to the other stem, as will be hereinafter more fully-explained.
The valve 13- is interposed between the lower end of thecylinder 6'- and bottom of the valve case 12-, and is thereby held against axial movement but free to move rotarily about its axis.
The valve stem -17--extends upwardly aV suficient distance to maintain connectlon with the tubular stem -8- in all positions and adjustments of the piston.` Y Y The passage 16- in the valve 13-,` is
\ of substantially the same area as that of either of the ports -14- or -15- so that when r red with one port the opposite side of t e valve will close the other port.
Suitable couplings, consisting in this instance of elbows -19- and -20-, are provided for connecting the inlet -14- and outlet -15 to the outlet -2- of the can v--1`-, and to a deliverytube -21- respectively, saidV couplings being removably secured from the valve case by screwV threads,
, shown in Fi -2, the coupling -19- being remova ly secured by a union 22- The delivery tube -21, which is flexible, is detachably secured at one end to the coupling 20- by means of a clamp -23, and its other end is provided with a nozzle -24- for directing the discharged grease to the' bearings to be lubricated, or to any other receiver7 the open end nozzle being normally closed by a--cap -25- through the medlum of a spring One of the bjects in making the couplings -19- and .-20- removable from the valve case is to permit the pump to be used in connection with grease pails as -1--- in au upright position, as shown in Figs. -5- and For example Fig. the coupling -19- is removed and the inlet nipple is projected through an opening in one side of the pail near the bottom and secured in place Y by a nut -27-.
In Fig.- -6- the pump is arranged' on the inside of the pail to rest upon the bottom thereof, and its outlet nipple is passed through an opening in the adjacent side of l'ts 14rand -15- for openopening which also controls the angular movement of the valve .-13- simultaneously with the angular movement of the piston. Y
The operation is as follows Assuming that the piston is at the limit of its downward movement, as shown in Fig. 2, and that it is desired to draw the grease from the can -1- into the interior of the valve 13- and pump case 6-',
then the operator will simply rotate the handle -10, which in turn will cause a similar rotation of the piston -7-, and valve -17- until the passage -1'6 is registered with the inlet 14-. g y
The piston is then raised to draw the grease from the can lthrough the open port -lland passage -16- into the interior ofthe valve and lower end of the pump case until the piston reaches the limit of its lpward movement, whereupon the han le lO- is turned a-half revolution to register the port -16- with'the outlet-15-, and close the inlet -14-, at which time the piston is forced downwardly to expel the grease previously drawn into the pump 'In order that the angular vmovement of the piston rod and valve may be limited to approximately a half revolution the piston rod and gland -9- are preferably angular in cross section to estabhsh a turnin connection between them, so that when t e rod voperated means for impartmg a reciprocal motion and angular motion around the axis of the pump to the piston, a valve controlling thepassage of grease to and from the pump,
and means actuated'by the angular movement 125 of2thiiston, for operating said valve.
operated means for imparting a reciprocal a grease gun, a piston pump, hand .of grease to and from the pum motion and rotary motion to the piston, a valve controlling the passage of grease to and from the pump, and means actuated b the rotary movement of the piston -indepen ently ot the reciprocatory movement for operating said valve.
3. In a grease gun, a piston pump, hand operated means for imparting a reciprocal motion and angular motion around the axis of thepump to the piston, and including a hollow rod, a valve controlling the passage and provided with a stem telescoping Wit in the hollow rod and splined thereon to turn therewith for o erating the valve.
4. n a grease gun, a piston pump, a valve case having an inlet port andan exit port, a valve communicating with the piston chamber and having means for alternately opening andv closing each port, hand operated means for reciprocating the piston and for moving it about its axis independently of its reciprocatory movement, and means actuated by the movement ofthe piston about its axis for o erating said valve.
5. n a grease gun, a piston pump, a valve case secured to the lower end of the pump cylinder and having its valve-chamber coaxial With said cylinder and provided with radial inlet and exit ports, a lcup-shaped valve turnable in said chamber and provided with a port-adapted to alternately register with the first namedv ports as the valve is rotated,fmeans for imparting independent reciprocatory and rotary movements to the pis-l ton, and means actuated by the rotary movement of the piston for operating the valve. 6. A piston pump provided with a handle turnable about the axis' of and relativelyto its cylinder, a valve case secured to the other end of the cylinder and provided with a valve.
chamber coaxial with the cylinder, said chamber having an inlet port and an exit port, a valve turnable in said case and controlling said ports, and means actuated by the turning of the handle for operating said valve.
