Serial m. 4510,G8019 My invention relates to working heads for windmills, pump jacks and the like; and the object is to provide simple and economic construction of devices for. use as windmills,

and the like and to provide the construction and devices with automatic lubricating means. The advantage of the improved construction is that-"it is simple and compact and easily installed'and easily opera center lift of the load is obtainedr Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims. 7 Reference is had to the l accompanying drawings which form a part of this applica-r indicate the same 1 V eral views.

Similar characters of reference are used-to parts throughout the sev- The'pump head is provided with a housing in two 'parts,the upper part 1 cooperating with the lower part 2 which forms thelubricating reservoir and both parts inclosingthe operatingparts. The main driving shaft 3 is journaled in bearings 4 and 5. The bearplace by the cap ,6 which is attached to the horizontal reservoir housing 7 by means of screw bolts 8. The bearing 5 is held in place by the cap 9 which i's'attached to the housing member 2, and by screw bolts 10.

A pinion 11 is rigid withshaft 3. and is driven by this shaft. The pinion 11' drives the cog wheel 12 which isrigid with the crank shaft 13, shown in'Fig. 4c. The crank shaft 3 '13 is journaled in bearings 14 which are at- V tached to housing member 2. See Figs. 2 and 3. .The bearings 14 are held'in place by'caps 15. The shaft 13 actuates the piston rod 16. Pitman bar 17 engages the crank. shaft 13 9 and is pivotally connected to" a driving-r .16.

- What I claim, is,

1. A working head for windmills, pump jacks, and the like, comprising a housing in upper and lower'parts, a driving shaft and gearing. actuated by said driving shaft for driving said crank shaft, said lower part or iaid housing serving as a lubricant reservoir,

a piston rod adapted to move vertically in said housing, aguide bearing forsaid piston rod, a driving head rigid with said piston rod and actuated by said crank,sh af;t,-alubricant distributer carried by said driving head for delivering lubricant to said guide bearing and totlie working parts of saidjworking head, and means actuated by said di'stributer for delivering lubricant from said reservoir 10 said distributer.

2. A working. head for windmills, pump jacks and the like comprising a housing in upper and lower parts, a guide bearing rigid with said upper part and pro ecting-.within he housing, a protecting cap rigid with said housing for a-pisto'n rod, a piston rod movable vertically in said housingfand in said cap, meansfor operating said piston rod; a distributer rigid with said piston rod and wrovided with a cavity in its upper face, said lower part of thehousing constituting an oil reservoir, a cylinderprojecting'down in said reservoir and made stationary therewith, a

hollow plunger'rod carried by said distrib 'ter andprojecting-down in said stationary cylinder and carrying a hollow, plunger, said cylinder having intake ports and. said rod forcing oil upwardly intofsaid distributer 7 when said plunger is forced below said ports, M and means for preventing oil from following said pistonrod down into a well.

3. A working head for windmills, pump? jacks, and the like' comprising a housing in upper and lower-parts, the latter forming an oil reservoir,*aguidebearing'rigid with said upper housing and constitutingin part means forlubricating afpiston rod, a plston rod moving vertically 1n said housmg; and

through said guide into said cap, means for rotuating said piston rod, adistributer rigid with said piston rod and prov ded with a I cavlty'inits upper face for supplying oil to '1 said guide, means actuated by said distributer for supplying oilthereto, and means for pre-. enting 011 from' followingsald piston rod down into the well consisting ofan upstandmg tubular pipe rigid with 'said lower housing and proJecting above the oil in said resertent oil from entering said upstanding pipe. In testimony whereof, I setmyhand, this 21st day of March, 1930.
