Specification of Letters Patent.
Patented Nov. 5, 1918.
Application filed February 23, 1917. Serial No. 150,369.
To all whom it may concern:
Be it known that I, AUGUST ANDnnsoN, a citizen of the United States, residing at Seattle, in the county of King, and State of Washington, have invented certain new and useful Improvements in Saw-oiling Devices, ofwhich the following is a spec1fica tion.
This invention relates to devices for applying oil and, more particularly, a, mixture of lubricating and kerosene oils to cross-cut saws which are utilized by loggers in felling trees containing pitchy substances.
Its principal object is to provide an oil receptacle having a relatively small discharge orifice, that will be of light weight to be handled conveniently of inexpensive construction, and made sufliciently durable and strong to withstand rough usage in the woods.
A further object is to rovide tree-engaging appliances for reliabl y retaining the receptacle in upright or in reverse positions, as may be required.
An additional object is to arrange said tree-engaging appliances So that they will not interfere with or endanger the operator in the use of the oiler.
These objects I attain by the devices illus trated in the accompanying drawings and hereinafter described.
In said drawings, Figure 1 is a side elevation of an embodiment of my invention shown hung in upright position from a tree. Fig. 2 is a similar view of the same in reverse position and shown as applied to feeding liquid to a saw blade, the spur attaching means being shown in section. Fig. 3 is a fragmentary front elevation of the receptacle when in reverse position to illustrate th spur and the preferred manner of attacping the same to the bottom of the receptac e.
The receptacle or oil-can is desirably formed of sheet metal having a body 5 and a contracted neck 6 which is formed to provide a screw-thread 7. 8 represents a cap having a screw-threaded portion 9 engageable with the threads on said neck and hav ing a tapering extremity 10 which terminates in relatively small outlet 11. A vent hole 12 is provided in the threaded portion of the can neck, and, on occasion, is exposed by partially unscrewing the cap.
13 represents a hook having a shank 14 which is clamped against the can-neck by means of a collar 15 and a clampin screw 16. Secured to the bottom 5 of tie can body and adjacent to its periphery is an attachment which is desirably formed of a single piece of sprin metal. As shown, said attachment is provi ed with arms which are looped, as at 16, and is bent therebetween to afford lugs 17 which serve to support a spur member 18. The latter is pivotally connected near one of its ends to said lugs by a pin 19 and at o posite sides of said pin the spur is forms with straight edges 20 and 20 which are arranged to be selectively held by the power of said attachment arms to bear against the base portion 21 of such attachment.
The can is supplied with a liquid which is composed of about equal quantities of lubricating oil and kerosene, the latter being utilized to cut, so to speak, the pitch from a saw and the oil for the purpose of allowin the saw to be easily drawn through the ker Ordinarily, the sawyer would use the device by grasping the can-body 5 in one hand and shaking the can so as to cause a small amount of the liquid to be ejected onto each side of the saw. Under such conditions, the spur 18 wouldbe laid against the can bottom, as represented in Fig. 1, so as not to lace'rate the arm or sleeve of the operator.
After being thus used, the can is then hung up by employing the hook 13 to engage in the bark of a tree, represented by T, and within convenient reach of the saw [yer from his station upon the socalled chopping board. When the tree being sawed is very pitchy, it is requisite that the saw should be supplied almost continuously with the liquid containing kerosene during the sawing of the tree and hitherto this has been accomplished by an attendant pouring the liquid onto the saw while two sawyersone at each end of the saw-efi'ected the reciprocation of the saw.
Inasmuch as such procedure requires the employment of an attendant and furthermore from the practice of sawing large trees at a considerable distance above the ground, the application of the liquid has hitherto been accomplished with difiiculty and unsatisfactorily. To overcome such objections, the spur 18 is turned about the pin 19 so as to rotrude laterally from the can, as shown in Fig. 2, and then engaged in the bark of the tree, indicated by T so that the can will be held in an inverted position above the saw S Without removing the same from the kerf K.
By then unscrewing the cap 8 to expose the vent hole 12, the liquid falls upon the saw either in a small stream or in the form of drops, according to the extent of the vent hole opening which is regulated by adjusting the cap. Other than adjusting the cap to regulate the liquid delivery, the apparatus requires no attention and Which may be done With one hand of a sawyer, Who continues to drag the saw With his other hand and Without interrupting the sawing, and obviating the danger of the saw becoming stuck in the kcrf.
From the foregoing, it will be seen that the present invention furnishes a liquid receptacle having devices Which serve (1) to afiord means to conveniently hang it to atree in upright position, or (2) in inverted position, and (3) is provided with devices for regulating the liquid delivery When in such inverted position.
What I claim, is
1. In combination with an oil can having a discharge opening at one end, of an attachment secured to the other end of the can and in proximity to the periphery thereof, said attachment being constructed of spring metal, and a spur pivotally connected to said attachment so as to be swung against the adjacent end of the can or in position to protrude laterally therefrom, said spur being provided with surfaces engageable with the can to yieldingly hold the same in either of the aforesaid positions.
2. In combination with an oil can, of a spring attachment secured to the bottom of the can, a spur pivotally connected to said attachment whereby the spur maybe turned up under the can or directed laterally therefrom, said spur being provided with means rendered operable by said attachment to yieldingly hold the same in either of the aforesaid positions.
