LUBRICATOR.
SPECIFICATION forming part of Letters Patent No. 745,435, dated December 1, 1903. x i Application filed April 11,1903. Serial No. 152,107* A(No model.)`
To cult whom, t may concern: Beit known that I, BENGT MV. HANSON, a citizen of Sweden., residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful lmprovements in Lubricators, of which the fol lowing is a specification. y My invention relates to lubricators of the oil-cup variety, and has for its object the provision of an improved oil-cup composed of few parts and one that may be cheaply manufactured either by hand or by machinery, as may be desired. y
A further object of the invention is the provision of a closure for the cup containing the lubricant and in connection with said lclosure improved means for normally causing it to cover the mouth of said cup, and thus eX- clude grit, dust, and other foreign matter.
In the accompanying drawings, Figure 1 is an enlarged view, inlongitudinal vertical section, of my improved lubricator with the parts in normal position; and Fig. 2 is a view similar to Fig. 1 with the closure raised to open the cup and a web ofm wicking in place in the bore of the bolt upon which said closure is mounted.
Like numerals designate similar parts in the several views.
Referring to the drawings, the numeral 5 designates in a general way the cup part of my improved lubricator, which comprises a receptacle 5 for oil or other lubricant and a tubular stem 52, which may be either plain or threaded, as shown, to enable it to be seated in an opening leading to the part to which the lubricant is to be supplied. This cup part is preferably formed from an integral piece of metal and may bc readily made from a rod of brass or other material by what are known as automatic metal-working machines, but the mode of its production is immaterial, for it maybe made either integral or sectional, and the tubular stem may be externally threaded or have aplain periphery, if desired, as above stated. In the base of the cup and upper part of the tubular stem 52 is formed an internally-threaded seat the latter being an enlargement of the bore 53 of said stem.
Designated by 7 is a bolt having a bore 7 and a port 7 2, through which wicking S, tted in the bore, may extend and dipinto the lubricant in the cup 5', as indicated in Fig. 2, when the lubricator is employed as a reservoir-cup. Then said lubricator is employed as an ordinary oil-cup, the position of this port will be changed to a point near the bottom of the cup, as shown by dotted`lines 9 in Fig. l. At its lower end the bolt 7 is reduced and threaded externallyV at 10 to engage the seat 6 and at its upper, extremity is provided with a hanged head 12, preferably having a kerf or slot 13 for the reception of a screw-driver, although said head maybe of other shape to be readily engaged by a tool for inserting and vwithdrawing the bolt without departure from the invention. Surrounding the upper part of the bolt is a spiral spring la for a purpose hereinafter described.
Designated by 15 is a cap or closure having 'a central bore 16 and at 'its lower end a circumferential inwardly-extending flange 15'. This cap is provided with a horizontal ila-nge 17, knurled or roughened ,upon its periphery to form a convenient grasping-surface, and with a circumferential shoulder 1 S, s uch shoulder fitting within the upper end of the cup 5 and the fia-n ge serving to prevent the entrance of dust, grit, or other foreign substances to the lubricant in the cup. Preferably the edge of the flange 17 is rounded or beveled at 17 to enable the nose of the oil-eau spout to be readily inserted between the Iiange and upper wall of the cup.
Like the body portion of the lubricator, the cap just described is preferably made of but one piece of metal and can be shaped and bored from stock of suitable proportions in the common automatic machines. As shown, the tubular part of the cap above the flange 17 is of conical shape to present a symmetrical appearance, but it may be of a different form, if desired.
In assembling the parts of my improved lubricator thespring 14 is slipped lupon bolt 7, and said bolt isthen inserted inthe bore 16 of the cap 15, and after this has been done the assembled cap and bolt are respectively placed over and within the cup 5', and the bolt is turned to cause its threaded stem to engage the internally-threaded seat 6 of the cup, and thus secure the parts in place.
Should it be necessary to replenish the supply of lubricant, the closure is raised either ICO by hand or by the spout of the oil-can to the position illustrated in Fig. 2, thereby compressing the spring 11i between the flange l5 and the under side of the head 12 of bolt 7, and after the cup has been filled said spring will react and immediately close the cap upon the top of the cup, as shown in Fig. l.
From the above description it will be seen that my improved lubricator is composed of but few parts, any and all of which may be readily made by the usual automatic machinery, that it is not only simple in construction, but is also efficient in action, and that it can be produced and its elements assembled at minimum expense.
My invention is not limited to the exact devices shown and described, nor to parts of the proportions and contours illustrated, nor is it limited to any specific kind of spring for closing the cap upon the cup.
Having thus described my invention, what I claim is-- A l. A lubricator comprising a cup having' an outlet a headed bolt projecting from said cup, and having a bore; a cap loose upon the bolt, and surrounding the head thereof; and means for forcing the cap to close the mouth of said cup.
