LUBRICATOR.

Specification of Letters Patent.

Patented Sept. 5, 1916.

Application filed July 7, 1915. Serial No. 38,612.

'To all whom t may concern Be it known that I, ROBERT M. AKIN, a citizen of the United States, and a resident of Ossining, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Lubricators, of which the following is a specication.

This invention relates to and has for an object to provide improved means for applying lubricant to bearing surfaces. It is peculiarly adapted for use in car axle boxes for applying a limited but constant supply of lubricant to the axles.

rllhe cotton waste and other fibrous materials generally employed in the axle boxes mats down and becomes soggy, which requires frequent stirring up because such material possesses no inherent' capability of recovery from compression, particularly that due to the vibration and j ar incident to the running of the car. The present lubricator, however, provides a mass of material which is of an absorptive character containing'cell spaces and capillary spaces of various sizes closely interrelated in such manner that the lubricant will be received and stored in sufficient quantities for use and conveyed in limited qualities, but constantly, to the bearing surfaces. It is preferably composed of absorptive fibrous strands and smooth surfaced unabsorptive resilient strands bundled together in a tangled mass in constant relative proportions. The ratio of the constituent elements remains constant while a particular mass is in use, and also remains constant in the general supply mass from which the individual or unit masses are taken from time to time, so that as the workman has occasion to take this material from the supply, whether he takes it when the bale is first opened or takes the last remnant, the predetermined andV original ratios will be found to exist.

In the drawings accompanying this specication, the invention has been depicted illustratively, in which drawings- Figure 1 is a perspective view of a mass of material intended to represent a mass of my improved lubricator. Figs. 2, 3 and 4 are perspective views of portions of combined material prior to being massed together, the characteristics of these being referred to below.

The mass, as for instance, the mass represented in Fig. 1, is preferably made up of a cord 5, or a plurality of cords, bundled together in a tangled mass. Before describing the mass which constitutes the lubricator it will be well to analyze its constituents. Briefly stated the cord 5 is made up of fibrous strands, and resilient material, the resiliency of which is not aected by a more or less liquidvlubricant.

The enlarged fragments of cord represented in Figs. 2, 3 and 4 are intended to be illustrative of the manner in which the cord is formed. In Fig. 2 the cord 52 is formed of a twisted cord 62 of some absorptive material. Linen or cotton will furnish a good absorptive fibrous material for this purpose. Around the cord 62 `is shown loosely wrapped a strand 7 2 of resilient non-fibrous material. In the present instance this latter is a very thin ribbon of bronze-a thin flat metal wire. In Fig. 3 the cord 53 is formed of a twisted cord 63similar to the twisted f cord 62 of Fig. 2, and a resilient non-fibrous strand 7 3, lthe cord 63 and the strand 73 being equally twisted together. The metallic ribbon is preferably of a smooth surface with smooth regular edges, initially polished and shiny.

The looseness o-f the original construction of the absorptive strand and the tightness or looseness of the resilient strand are determined by the use to which the lubricator is to be put and also by the quality and condition of the lubricant which is to be applied thereby. In some instances a compound cord or cable will be desirable. This is illustrated in Fig. 4. The cord 54 is shown composed of two cords 54a twisted together. Each of these cords 54a is shown having its fibrous strand 64 composed of two tightly twisted strands 64a tightly twisted together, around which is wrapped the resilient strand 74. In the illustration it is sho-wn wrapped in a reverse direction to the twist of the cord 64. In this instance the combined structure is resilient in addition to the resiliency of the metallic ribbon 74.

As before stated these are given as illustrative instances of what I have found to be the preferable form of construction at the present time for the uses to which I have applied the lubricator. For cheapness and uniformity of product, suitable machinery is employed in the manufacture of the cord 5. A quantity of this cord after being fabricated is bundled together in atangled-mass and the relative proportions of the iibrous absorptive material and the unabsorptive resilient material remain constant in that mass both during the time that the mass is drawn upon by the various workmen to supply the demands and also while such material is in use.

TWhat I claim is l. The herein described lubricator comprising cords formed of iibrous strands wound around with and held together by metallic ribbons, said metallic ribbons lying entirely on the outside of the cords respectively thus formed. v

2. The herein described lubricator comprising` a cord formed of librous strands wound about with a flat metallic ribbon, one face of said ribbon being always against said fibrous strands and the other face always turned outwardly to resist abrasion.

3. The herein described lubricator comprising a cord formed of fibrous material wound around with a flat metallic ribbon, one face of said ribbon lying always against the iibrous material and the other face thereof projecting radially of the cord beyond the brous material.

4. The herein described lubricator comprising a cord formed of librous material having a flat metallic binder wound helically n therearound, said binder projecting beyond the fibrous portions of said cord.

5. The herein described lubricator comprising a cord formed of fibrous strands armored by winding helically therearound a lat metallic ribbon.

The herein described lubricator coniprising fibrous material spun into a yarn and wrapped helically with a iiat metallic strand, one face of said metallic strand lying always against the iibrous material.

7 The herein described lubricator comprising fibrous material formed into a twisted yarn and wrapped helically with a flat metallic strand in a direction opposite to the direction of twist in the yarn, one face of said metallic strand lying always against the fibrous material. 8. The herein described lubricator comprising fibrous material formed into a twisted yarn and armored with a helically wound flat metallic ribbon.

Signed at New York, in the county oi New York and State of New York, this 1st day of July, 1915, before two subscribing witnesses.
