MEANS FOR CLEANING AND OILING THE SKIDS OF SKIDWAYS.

Specification of Letters Patent.

Patented May 4, 1915.

Original application filed June 20, 1914, Serial No. 846,411. Divided and this application filed November 2,

To all whom it may concern:

Be it known that I, Fnnonnron W. KoLB, a citizen of the United States, residing at La Conner, in the county of Skagit and State of Washington, have invented certain new and useful Improvements in Means for Cleaning and Oiling the Skids of Skidways, of which the following is a specification, reference being had to the accompanying drawings.

This application is a division of an application filed by me for skid cleaners and oilers, on June 20, 1914, Serial No. 8%,411, and this invention relates to devices for cleaning and lubricating the skids of skidways which are used in lumber camps and upon which logs are drawn to railroad sidings or to banks of streams.

In the use of skidways of the character above stated a train of logs is drawn along the skidway by any suitable means, these logs being connected to a carriage and traveling one after the other in line with each other. It isnecessary as the logs are'drawn along the skidway that oil or other lubricant be applied to the skids on a line with the logs so that the logs may travel easily over the skids. If bark, chips or like extraneous matter has accumulated upon the skids, and then if oil be applied to the skids, it will be applied upon the chips or bits of bark and the first log of the train striking these chips will knock them off, and as a consequence the skid will not be oiled. It is the primary object of my invention to provide a skid cleaning and lubricating device which will act first to clear away chips or dirt from the middle of the skid log and then immediately thereafter apply oil thereto, the oil being applied automatically as the oiling device arrives over a skid log, the oiling mechanism being held inoperative between the skid logs so that no oil may be wasted.

It is a further object of my invention to provide a carriage having the form of a sled with runners of such length as to bridge the space between the skid logs, this carriage supporting the cleaning mechanism and the oil applying mechanism and being also provided with means whereby a train of logs may be drawn behind it in the usual manner.

Other objects will appear in the course of the following description:

WVith this and other objects in view as Serial No. 869,905.

will become more fully apparent as the description proceeds, my invention consists in the novel construction, combination, and arrangement of parts, to be hereinafter more fully described, claimed, and illustrated in the accompanying drawing, in which- Figure 1 is a side elevational view of my device; Fig. 2 is a vertical sectional view of the air pump on line 22 of Fig. 1; Fig. 3 is a detail view in plan showing the air pump; Fig. 4c is a fragmentary elevational view showing the manner of connecting one of the lift bars of the cross head for operating the air pump to the cylinder of the pump; and Fig. 5 is a vertical sectional view of a portion of the cylinder and piston of the air pump showing the location of one of the valve openings therein.

Referring more particularly to the drawing, the numeral 1 designates the skids of a skidway, upon which my improved device is adapted to slide, the device including a pair of spaced parallel runners 2 upon the upper edges of which, at their forward ends, is secured a plurality of cross bars or timbers 3 which connect therunners together, and mounted upon the bars 3 is a platform 4. Secured upon the platform 4, adjacent its forward end, is a base 5 which is provided with an upstanding internally thread ed neck 6, the neck receiving the lower threaded end of the air pump cylinder 7 and the base having a discharge opening 8 formed centrally therein. The cylinder 7 is provided with a removable cover 9, the cover having depending spring catches 10 connected thereto which are adapted for engagement with outwardly extending lugs 11 formed on the cylinder adjacent its upper end, whereby the cover is removably con nected to'the top of the cylinder. 1he cover is provided with a central opening 12, and a guide plate 13 is arranged across the top and is also provided with an opening therein which communicates with the opening 12 in the cover, and a piston rod 1a is passed through the registering openings, the lower end of the piston rod being threaded and having a piston 16 detachably mounted thereon. Connected to the upper end of the piston rod which projects above the cylinder, is a cross head 17 the opposite ends of which project beyond the cylinder at diametrically opposite points, and pivotally connected to the opposite ends of the cross ends of the levers are pivotally connected at head are vertically disposed lift bars 18 which extend downwardly through slots 19 in the opposite ends of the guide plate 13, and are slidably disposed through guide boxes 20 connected to the periphery of the cylinder at diametrically opposite thereof, intermediate of its ends.

Secured to the upper face of the platform 4, forwardly of the cylinder 7, are spaced bearing members 21 in which the opposite ends of a supporting rod 22 are mounted, and pivotally supported upon the opposite ends of the rod between the members 21 are the forwardly and upwardly extending arms 23 of a pair of angular levers. These forwardly extending arms 23 extend downward to a point below the runners so as to be disposed in the path of the skids and the levers then extend upwardly and rearwardly so as to provide the rear arms 24 which are, operatively connected to the pump, as will be later stated. lhe arms 23 of the levers are 7 each provided adjacent their forward ends with a plurality of openings 26 so that the levers may have the rod 22 which forms the pivotal support of said levers. passed through any one of said openings and thereby regulate the distance to which the levers shall project below the runners. The forward and rear ends of the levers project through-slots in the platform, and the inner their extremities to the lower ends of connecting rods 27 ,the upper ends of the connecting rods being pivotally mounted upon studs 28 which project from sleeves 29, the sleeves being mounted upon the lift bars 18 and being secured thereupon in adjusted position-by the set screws 20 which project through the sleeves into engagement with the lift bars. It will be seen that when the arms 23 are raised, due to their engagement with'a skid, the cross head 17 is also raised,

thereby moving the, piston 16 upwardly within the cylinder. -To return the piston to its lowermost position and'to normally hold the same in the lower end of the cylinder, any desired number of weight disks 31 may be secured upon the pistonrod above the piston. V

The cover 9 is provided with a plurality of air openings 32 and the piston 16 also has openings 32 formed therein, the piston haV: ing flapvalves 33 secured to its under face, the valves 33 normally closing the openings 32 in the piston, and being forced away from the openings as the piston is raised within the cylinder to allow air to pass through the piston into the space between the upper face of the base of the. cylinder and the lower 7 face of the piston. It will be seen that as the piston 16 is lowered, thefiap valves 33 are forced against the lower face of the piston to close the openings therein, and the air found in the' compression space between the points base 5 and the under face of the cylinder is forced through the opening 8 against the upper faceof the skid to clean the same. A raised ring 34 is formed on the upper face of the base, the ring having a groove 35 formed therein to receive a rubber or other flexible ring 36, against which the piston will strike at the limit of its downward movement, this ring forming an air tight chamber between itself and the cylinder, thus alleviating the jar which would otherwise be imposed upon the base. Mounted on the platform 4, rearwardly of the air pump is an oil pump generally designated by the numeral 37 which is operated by a lever 38, the lever, pump, and the intermediary mechanism being fully described in the application. filed by me, Serial No. 846,411.

The operation of. my device is as follows :The draft animals are driven forwardly to move the logs over the skids in the usual manner, the platform upon which my improved mechanism is mounted being connected to the draft animalsforwardly of the foremost log. It will be seen'that when the arm 23 engages a skid, the lever is raised, which operation raises the piston 16 in the cylinder 7' of the air pump, thereby drawing air into the chamber below the piston, andthat when the lever passes over the skid, the weights 31 force the piston; downwardly, thereby discharging air from theopening 8 against the top of the skid to blow any dirt which might be upon the skid ofi thesame.

From the above description, taken in connection 'with'the accompanying drawing, it will be seen that I have provided a simple mechanism for cleaning the skidways, and that this mechanism used in connection with the oilpump 37 serves to provide a mechanism which will thoroughly. clean and oil the skids in advance of the logs, so that the logs may easilv slip along the skidway with minimum resistance.

' It is to be noted that the cleaning device is really part of the oiling mechanism, for the reason that there would be no object in cleaning the skids of chips and dirt were it not thatoil was to be applied thereto and were it not that if oil were applied to the chips and dirt the following log would scrape the foreign matter from the log and leave the log unlubricated.
