Specification of Letters Patent.
Application tiled May 5, 1908. Serial No. 430,917.
of syringe used for handling oils and grease to enable oil cups and grease cups on machinery to be readily filled. It is particularly useful in the automobile industry Where gear cases and cups are to be" filled with heavy lubricants such as grease, and the object of my invention is to enable these heavy lubricants to be quicklyhandled with the hand oiler and to avoid the difiiculty heretofore experienced in filling the hand oiler with the-grease. I attain this end by a peculiar construction which enables me to plunge the cylinder of the-hand oiler into a body of grease and withdraw the cylinder and with it the mass of grease inclosed thereby. 1
My invention also involves a novel device by means of which the hand oiler may be instantly converted from a straight piston motion under direct pressure to a screw feed piston or vice 'versa.
The invention involves various other fea-' tures of importance and all will be fully set forth hereinafter and particularly pointed out in the claims.
Reference is had to the accompanying drawings which "represent one'of the variousforms in which my invention may be practically embodied, in which drawings,
Figure 1 is a side elevation of the device; Fig. 2 is a. central longitudinal section of the same; and Fig. 3 is a top view of the barrel of the hand oiler with the piston or follower rod in section. V
10 indicates the inner barrel or cylinder proper and 11 an outer barrel which is spaced from theinne'r barrel and has a tapering portion 12 at thedischarge end ,which is engaged by the beveled lower edge 14 of the inner cylinder 10. The end wall 15 of the outer cylinder 11 carries the-usual discharge spout 16. At the outer end the inner cylinder 10 is screwed into an internally threaded flange 17 on the head 18 and said head is provided'with two or more pins 191 inner cylinder.

The inner cylinder,'when withdrawn, may beplunged into a body of grease and withdrawn therefrom bringing with it a full charge of grease which may be readily expelled upon reassembling the parts as shown in Figs 1 and 2. 21 indicates a vent opening in the inner cylinder which is covered by a check valve 22 opening outward. When the inner cylinder 10 is plunged into the grease the check valve 22 opens to allow the air to pass from the inner cylinder and upon withdrawal of the inner cylinder the check valve closes preventing the air from reentering the cylinder and insuring the removal of the grease with the same. The check valve 22 is not absolutely essential and may be dispensed with if desired, the operator then holding his finger over the opening 21 during the withdrawal of the The outer cylinder is provided to furnish a conveniently arranged outer or" discharge end wall for the inner cylinder and also to prevent soiling ones hands by the necessity of grasping the inner cylinder after the same has been plunged into the grease. Upon the withdrawal of the inner cylinder from the grease a certain quantity thereof will necessarily adhere to I the outer wall of the inner cylinder but this is covered by the outer cylinder when the parts are reassembled so that the device may greasing the hands of the user.
The inner cylinder is provided with the usual piston ,or follower 23'for forcingout the oil or grease and this is connected with a rod 24 having a square or V-shaped thread thereon. Said rod passes through a small an openingguide boss 25 formed around central in the top 18. Coactin with the threaded rod 24 is a substantial y semi-circular,nut-section 26 which may be made to engage or disengage the screw 24 at will.
When disengaged, the follower may be ac- 26 toward and from the screw 24. The said guide 28 has at each side thereof a projecting, overhanging flange 30 which flanges form finger pieces for the manipulation of the hand oiler. The nut section 26 may be operated back and forth by any desired means. I have'here shown an elbow lever 31 articulated to a lug 32 on the nut section and coacting with two spring catches 33 which hold the lever in either one of its I two positions.
In the operation of the device, therefore, manipulation of the elbow lever 31 throws the nut section 26 in and out of action at will and converts the hand oiler from one type to another, thus adapting'it for use with heavy; oils and greases as well as light lubricating oils." The vent orifice 21 being immediately below the innermost position of the follower will not interfere materially with the action of the follower in. sucking into the cylinder light liquid lubricants. The operation of filling the hand oiler with grease may be very easily and quickly ,performed, the operator grasping the outer cylinder 11 in one hand and the handles 30 in the other and by twisting the outer cylinder freeing the pins 19 from the bayonet slots 20, thus allowing the inner cylinder to be withdrawn and plunged into the grease as explained. Upon reentering the inner cyllnder into the outer cylinder and locking it by the pins '19 and slots 20, all danger of soiling the hands of the user by the grease which may be spread over the outer surface- .and piston cylinder from injury due to blows tending to'indent or fracture the inner cylinder.
Preferably the innercylinder 10 is provided at its lower portion with outwardly projecting lugs 34 which serve two important functions; first, to guide the inner cylso that when such cylinder is withdrawn air may pass down these channels to break the vacuum at the base of the inner cyllnder.
Various changes may be made in the form,
proportions and .details ofthe device without departin from the spirit, of my invention since I ho not consider myself limited to the precise details shown in the drawings, 'but am entitled to all variations thereof as may fall within the scope of the claims.
Having thus described my invention, what I claimv as new and desire to secure by Letters Patent of the United States is:
l. A hand oiler having an inner and an outer cylinder separable from each other at will, the inner cylinder being open at one end and constructed of metal sufiiciently rigid to enable it to be plunged into a mass of stiif grease to fill the same when removed from the outer cylinder, a follower for ej ecting the grease from thelopen end of sa 1d inner cylinder, and an air outlet for permitting the escape of air from beneath the follower during the plunging of the open end of the cylinder into the grease, the grease.
being prevented from passin therethrough durin .the major portion 0 the travel of the'fo lower.
2. A hand oiler including two concentric cylinders, the inner cylinder having an open end and a closed end. and the outer cylinder having an open end and an outlet-or deliverv end means for detachably securing the cylinders together with the open end of the inner cyl nder closed by the outlet end of the outer cylinder to prevent the passage of grease from theinner cylinder to the space etween the cylinder, an air outlet from the inner cylinder to the outer cylinder adjacent the closed end of the former an outwardly opening =valve controlling said air outlet and a piston movable'within the inner cylinder to a position between the closed end and the air outlet.
3. A hand oiler having innerand outer cylinders, a head at the upper end of the inner cylinder, means for releasably fastenin together the upper ends of the two cylin ers, and a piston or follower operating in the inner cylinder, the outer cylinder having at its lower end a wall engagm with the lower end of the inner cylinder an forming a bottom therefor and preventing the passage of grease to the space between the cylinders when the parts are in assembled relationship. Y
4. A hand oiler having inner and outer cylinders of which the inner has an open 'two cylinders together, said means exerting a downward thrust on the inner cylinder to engage its lower edgefirmly with the adjacent end of the outer cylinder.
5. A hand oiler having separable inner and outer cylinders, a piston operating in the inner cylinder and an exterior lateral lip on the lower portion of the inner cylinder adapted to guide the inner cylinder in its movement in and out of the outer cylinder and to form a channel in the ease when the inner cylinder is plunged t erein to be filled to permit air.to pass to the base of the cylinder to break the vacuum upon the withdrawal of the c linder from the grease.
-6. A'hand oi er including a cylinder havtubular ing a head, a follower in the cylinder,
guide on the head and havin opening in the side thereof, a threade rod connected to the follower and extendin through said guide, a nut section in sai opening and a lever pivoted to the head and to the-nut-section for moving the latter into or out of engagement with the rod.
In testimony whereof I have signed my 5 name to this specification in the presence of two subscribing witnesses.
