LOGGING DEVICE.

Specification of Letters Patent.

Patented Aug. 11, 1908.

Application filed May 15, 1906. Serial No. 317,020.

To all whom it may concern:

Be it known that I, IhnnoNYMUs Znou, a citizen of the United States, residing at Wilburton, in thecounty of King and State of \Vashington, have invented new and useful Improvements in Logging Devices, of which the followingis a specification.

My invention relates to logging devices in which a car is equipped with locomotive means and a stationary cable, said cable being made of wire, Manila rope or any composition adapted to the handling of heavy weights and which is possessed of good wearing qualities.

The objects of my invention are to construct a logging device which is adapted to haul logs from the woods and may operate on very steep grades without relying on the weight ortractive power of the locomotive as a means for applying the power in hauling the logs. I do not wish, however, to be limited to logging only as I may wish to use my device as a locomotive means where it is desired to haul heavy weights and where speed alone is not the most important factor. In my device the rope is preferably rigidly secured at one end and adjustably secured at its other end and lies substantially midway of the rails when the holding down pieces are used and slightly toward the inner rail on curves in the road-bed of the railway on which I may operate my device.

I have shown in the accompanying drawings a portion of the track in which the holding down pieces are not used. This construction is preferred in temporary installations of my device and it is obvious that when the car is traveling in a depression as would occur in a gulch or a ravine running transversely of the road bed of my device the rope will be forced downwardly toward the tics and as the car advances from the said doression the said rope wi l become slackened. It may be desirable to take up this slack rope and I have here shown a weight attached to one end of said rope and adapted to keep a tension on said r0 )e. In this case I have shown the aforesaid weight as hung from the limb of a tree but I do not wish to be limited to this specific construction within the scope of my intent.

ton heads attached to the said pistons which will take up any slack there ma be in the aforesaid cable. The shaft which is nearest the slidably mounted snaft is provided in this case with a single drivin sheave and having on each side of the said driving sheave one or more loosely mounted sheaves adapted to co-act with the said sheaves on said slidablymounted shaft in taking up the slack in the said cable; the third or remaining shaft is provided with a double grooved sheave rigidly secured to the said shaft and adapted to receive the cable from one of the said loosely mounted sheaves on the second named shaft and to permit the said'cable to travel around the said third mentioned shaft having the said grooved double sheave and thence on to the sheave on the second named shaft which is rigidly secured to the said shaft and from thence around the second groove in the third named shaft and then on to one of the loosely mounted sheaves on the second named shaft and thence around one of the loosely mounted sheaves on the first named or slidably mounted shaft. I do not wish however, to be limited to one driving sheave on the second named shaft nor to a double grooved sheave on the third named shaft as it may be desirable to increase the number of driving sheaves to prevent the aforesaid cable from slipping on the said driving sheaves.

I do not wish to be limited to a winch consisting of three shafts and have here shown one having but two and with this construction the cable passes around both shafts- 1 UNITED sTATEsPATENTOFFIGE from under to over the several sheaves as shown, one of the said sheaves being rigidl The ocoinotive car is here showtiwith a. l secured to the shaft having the gear. This and ravines and when the said holdin down pieces are used I may deem it advisabl e to do away with the weight. heretofore described as being secured to the end of said cable and which is supported to the limb of a .tree, as with the use of these holding down pieces and curve pieces the slack in the cable will be reduced to a minimum making it possible to take all of the slack up by separating the slidably mounted shaft from those having a driving sheave attached thereto. The engine or engines of my device are rovided with a reverse gear which enables t ie aforesaid car to run in either direction as may be desired.

1 attain these objects by the mechanism illustrated in the accompanying drawings in which Figure 1 is a transverse section showing the disposition of the ports in the tightening drum cylinder throttle. Fig. 2 is a side ele vation of my device with a portion of the car and two of the wheels removed.

sheaves. The reference numerals refer to that portion of the cable which rests on the sheave corresponding to the reference nu preferred construction of my meral in the Similar reference numerals refer to similar parts throughout the several views in the' accompau 'ing drawings.

- I have s rown the motive power for revolving the several shafts as being a single or double cylindered engine preferably the latter adapted to drive a crank shaft 3 havin a pinion t adapted to mesh with a gear wheel 5 being adapted to mesh with a similar gear wheel 5' the said gear wheel 5 is rigidly secured to a driving shaft (0) and which also has a double geared sheave 50 having grooves 51 and 52 on its periphery. The cable 8 first asses between the guiding idlers 30 and 31 t ienee half-way round the sheave 53 thence on to the sheave 54 and from the sheave 54 the said cable 8 then travels on a portion of the sheave 55 and thence on to the driving sheave 50 in the groove 5'2 and nearly around the said driving sheave 50 on to a second driving sheave 56 passing nearly entirely around the said drivmg sheave 56 and from thence returning to the said driving sheave 50 in a groove 51 passing nearly entirely around the sheave 50 and from thence on to a portion of the sheave 57 and from thence on to the sheave 58 passin halfway around the said sheave 58 on to a 5 leave 59 passing half-via around the said sheave 59 and on to a sheave 60 and passing halfway around the said sheave 60 on to a sheave 61 and passing half-way around the said sheave 61 and thence on to a sheave 62 and thence the said cable 8 asses from the said winch between the guiding idlers 2S and '29.

The sheaves 54. 58, 60 and 62' are loosel mounted on a shaft (0) the said shaft (0) 1S slidabl mounted by means of journal boxes 11 ant 11' and guides 12 and 13 the said journal boxes 11 and 11 have attached thereto one end of piston rods as 14 which are attached to pistons as 65 said pistons 65 are fitted in sheave tightening cy inders 16 and 17 which are supplied with steam through a steam pipe 19 and a three-way valve 20 said threeway valve 20 is adapted to admit steam to the said sheave tightenin cylinders 16 and 17 and to exhaust the sai steam from said cylinders 16 and 17 when desired. and 61 are mounted on a shaft (1)). In Fig. l, I have shown a section through the center of the aforesaid valve 20 showing the valve in the exhaust position, the steam as shown passing through the exhaust port 23 and shows the steam port 22 as being shut off.

It is obvious that: when the valve 21 is turned to a position which will allow steam passing through the said port 22 and a passage 19 which is in communication with the substantially stationary and adapted to journal-the aforesaid shaft (b), gear wheel 5, the driving sheaves 5G and tightener sheaves 61 59 57- 55 and 53, the said journal boxes 11 are slidably mounted in the framework 10 and are adapted to be operated as heretofore described by means of the aforesaid valve 20.

I have shown a reversing lever 25 adapted to operate the reverse link motion 70, thus affording a means for reversing the several parts here shown in both directions. The said link mot-ion is of the usual type common to which construction. I have also shown as projecting above the car deck of my device a lever 73 adapted to operate a brake 72 which preferably bears against the internal surface of the brake rim 71 which is rigidly secured to the aforesaid gear wheel 5. I do not wish however to be limited to this particular form of brake nor do I wish to be limited to brake 72 as being the only brake means for stopping the said car of niv device as I may wish to apply air brakes of the usual type on the wheels of the car of my device or in fact any form of brake common to railway equipment.

I have provided a protection plate 31 adapted to cause holding down pieces 32 and 33 to beforced in a depressed position shown by broken lines in F ig. 5', the said holding down pieces are preferably mounted in de- I supplied with steam from a boiler 18, said pressiuns of the road bed of my device and are adapted to hold the said cable 8 from being raised from the track as shown in Fig. S) when a strain is applied thereto. The guiding idlers 28, 29, 30, and 31 are so disposed as to cause the said cable 8 to be forced toward the ties as shown in broken linesin Fig. 5, and when said cable 8 is in its lowered position, viz: when the car of my device is passing the portion of the track having the said holding down pieces 32 and 33, the said holdmg down pieces 32 and 33 will be thrown apart as shown in broken lines in Fig. 5.

The said protection plate 31 as the car advances will enter the opening between the open or hooked end of the said holding down pieces 32 and 33 and cause the said holding down pieces 32 and 33 to be separated and depressed by the said protection plate. the said holding down pieces 32 and 33 remaining in this depressed position until the said car device as shown in Fig. 8. guiding idlers :23 and 29 which are carried by adapted to operate upon 'a lag on the lower end of the said holding down pieces 32 and 33 and cause the said holding down pieces to return to their normal position as shown in Fig.

5, when the aforesaid car of my device has passed the above named portion of the track or roadbed of the said holding down pieces 32 and are depressed. In Fig. 6, I have shown curve pieces as 35 adapted to prevent the said cable from being thrown toward the inner rail of the curves in the roadbcd of my The aforesaid the car of my device will cause the said cable 8 to be thrown toward the center of the track as shown in broken lines in Fig. 6, thus allowing the said cable to travel between the guiding idlers28, 29, 30, and 31, and over the several shafts carried bv the car of my device as heretofore describet I do not wish to be limited to the construction shown in the accompanying drawings but wish to make such changes as are within the scope of my patent.
