OILER.

Application filed October 6, 1922.

T0 all cti/tom t may concern:

Be it known that l, THOMAS SMITH, aV

citizen of the United States, residing at the city of St. Louis and State of Missouri, have invented a new and useful Oiler, of which the following is a specification.

rl"his invention relates to improvements in oilers, and consists in the novel construction hereinafter disclosed.

An object of the invention is to provide an oiler adapted to be applied to a mechanism having a stationary and a reciprocating nieniber, which oiler delivers intermittently measured quantities of lubricant to selected parts of the mechanism.

Additional advantages of the invention will be apparent from the following detailed description thereof, taken in connection with the accompanying drawing in which- Fig. 1 is a front elevation of a. punch press showing the invention applied thereto.

Fig. 2 is a detailed view, in plan, of a part of the oiler mechanism.

' F ig. 3 is a cross section taken on the line 33 of Fig. 2 illustrating further details of the construction.

As illustrated in the drawing the invention is shown as applied to a punch press, although it will be understood that its application is not necessarily limited to such a machine, but that it may be applied to any mechanism having a stationary and reciproeating part that requires lubrication at sc lected points of the mechanism.

As illustrated in the drawing 1 is a portion of the frame of the punch press having a bed 2 and a die block 3. Above the bed plate is a reciprocating head l of the punch press supporting the punch members 5. T his mechanism is of usual construction and is simply illustrated for the purpose of showing application of the oiler of the present invention.

The oiler mechanism consists of a casing G adapted to be secured by straps 7, or other suitable means, to the reciprocating head of the punch press, in the embodiment shown the casing being of sutiicient length to extend fully across the head of the punch press so that more than one punch member may be lubricated by the device, although it will he understood that the device may be used l'or a single punch only.

For cleaning or turning the casing 6 it is provided with an opening 8 through its under face which is closed by a screw 9, and at Serial No. 592,701.

one end there is an opening 10 closed by a screw 11. Depending from the casing 6 near each end are valve cases 12 which are in the form of tubular members having one end threaded to connect into a passage 13 through the casing 6, and the 'other end rounded so that the inner surface forms a valve seat for a ball valve 14. Nozzles 15 are screwed into the lower ends of theJ valve cases 12, said nozzles being dellected so that the discharge ends thereof may be brought in proximity to the punch members. The valve cases l2 constitute reservoirs in which lubricant is delivered from the casing 6. rlhese reservoirs are constantly filled from a source of supply such, for instance, as a container 16 attached to some stationaryA part of the mechanism and connected with the casing 6 by a liexible conduit 17, the end of which is provided with an elbow 18 connected to a threaded nipple 19 at the end of the casing 6.

As the machine reciprocates the vibration raises the ball valves 14.- to permit the passage of a measured quantity of lubricant to the nozzles 15 upon each stroke of the punch press. The lubricant is carried through the nozzles 15 by gravity and discharged on the punch members of the mechanism upon each stroke of the mechanism.

It will be understood that the vibration of the reciprocating head of the punch press lifts the ball valves 111- intermittently so that there is not a constantl flow of lubricant to the punch members, but only sufficient quantity of the lubricant is delivered to maintain the punch and die members in proper condition for effective operation.

From the foregoing the operation of the device will be readily understood and it will also be understood that the principle of the mechanism may be readily applied in other reciprocating` machines in which there is a vibration su'llicient to operate the ball valve.

I do not limit myself unessentially, but what claim and desire to secure by Letters Patent is 1. An oiler adapted to be applied to a machine having a stationary and reciprocating part, comprising al conduit supported by and moving with the reciprocating part, and a valve inV said conduit operated solely by the vibration of the reciprocating part of the machine, and a nozzle leading from said valve to deliver measured quantities of lubricant to a selected part of the machine.

2. An oiler adapted to be applied to a machine having a Stationary and reciprocating part, comprising a casing carried by and moving with seid reciprocating part, a nozzle leading from said casing for delivering lubricant to a selected part of the ma-V chine, and a valve between said casing and said nozzle operated intermittently and solely by the reciproeation of said reciprocating part to deliver measured quantities of lubricant to the nozzle.

3. An oiler adapted to be applied to a ma-v chine having a stationary and reciprocating part, comprising a casing carried by and moving With said reciprocating part, a nozzle for delivering lubricant to a selected part oi"- the machine, a 'valve between said caising'and said nozzle operated intermitv tently Vand solely by the reciprocation of the machine to deliver measured quantities of lubricant to the nozzle, a container supported by said stationary partof the machine7 ing a stationary part, a reciprocating part,V and a plurality of selected elements supported and reciprocated by said reciprocating part, of an oiler comprising a. easing supported by and moving with said reciprocating element7 a plurality of nozzles in connection ivith the casing, a valve between each olf said nozzles and said easing, each coniprising Ia tubular valve case connected into said easing and having a lvalve seat therein, a ball valve member on each Seat adapted to be operated solely by the vibration of said reciprocating part ot' the machine to deliver measured quantities of lubricant to said nozzles upon each reciprocation of said reciprocating part.
