THREE-SPEED ROTARY DRALW WORKS.
Application filed June 25, 1923.- Serial No. 647,549. i
To all may concern:
Be it known that we, EDWIN \V. Gonssn and VILLIAM DfDAvinsoN, citizens of the United States, residing at Los Angeles, in
i the county of Los 'Angeles and State of 2 for the-highest driving speed for the drum and in order toobtain a third speed, that is, the highest speed used, it has been necessary to drive the engine at an excessively higli speed. The general oh- I ject of this invention is to provide a simple construction applicable to the draw works mechanism as now used and without necessitating an increase in its length, but which will adapt the same for developing three driving speeds for the drum with one engine speed. 7
Further objects of the invention will appear hereinafter. The invention consists in the novel parts and combination of parts to be described hereinafter, all of which contribute to produce an ellicient three speed rotary draw works.
A preferred embodiment. of the invention is described in the following specification while the broad scope of the invention is pointed out in the appended claims.
The drawing which consists of one figure is a side elevation and partial section showing the frame partially broken awav with portions of the mechanism broken away and in section.
I Th'e'rot'ary draw works mechanism coinprises a. drum shaft carrying a drum opv osite to which there is mounted a riving shaft. In applying our invention, We provide a low speed driving connection between the shafts including a member rigid on one of the shafts and a loose member on' the other, with a clutch. for driving through the low-speed connection at will; we also provide an intermediate-speed driving connection between'the shafts including a member rigid on one of the shafts and a# loose member on the other shaft, with its corresponding clutch for driving through the intermediate speed at will; we also pro vide a high speed driving connection between the shafts including a member rigid on one of the shafts and a loose member on the other shaft with its corresponding clutch for driving through the high speed connec tion, and we provide-means corresponding to each clutch for operating the'same independently.
;\Ve shall .now describe this mechanism more in detail, and refer to the drawing in which 1 represents a drum shaft carrying'a drum 2 rigidly keyed to it, said shaft being mounted on bearings supported on' three posts, comprisingtwo end posts 3 and 4 and an intermediate post 5. In the upper part of the. frame a line shaft or driving shaft 6 is rotatably supported, and between these shafts 6 and 1 we provide three driving connections, any one of which may be em loyed at will to drive the drum shaft. n the driving shaft we provide a rigid low speed driving member which may be in the form of a driving sprocket wheel 7 wln'ch is connected by a sprocket chain 8 with an alining low speed sprocket wheel 9 which is loose on the shaft l and which is rovided with its own clutch 10 adapted to e opened and closed at will by means .of a lever 11. This low speed clutch l0 issiinilar in construction to an intermediatespeed clutch 12 which is located at .the other end of the shaft 1 between the posts 4: and 5 and which operates to connet-t aloose driven sprocket Wheel 13 on the shaft 1, to the shaft when it is desired to drive the drum at an intermediate speed."
This sprocket wheel 13 is in alinement with a driving sprocket wheel 14 on the shaft 6 and is driven from it by a sprocket chain 15. The movable member 16 of the clutch 12 may be shifted at will by means of a lever 17 fulcrumed at 18 and actuated bya foot lever 19 at the left of the frame. A 5 ring 20 attached to the lever 17 normally olds this clutch 0 'en. -The construction of this clutch 12 an the clutch'lO is substantially the same and these clutches are preferably one way drive clutches,that isto say, the
*mOvaIilecIutch member of each clutch is roclutc es will be inafter.
vided with a str'ai the face or 'shoul' ht driving face,-suc as The urpose of these beveled faces'on'thcse I I In order td enable the drum 2 tobe driven at a high speed we provide a high, speed driving memberzin the form 'ofa sprocket wheel 23 which is loose on the driving shaft 2 (Sand this sprocket wheel is connected b a chain 24 with in the .form is the same to stood, however, necessarily. do sprocket I a suitable clutch 28 with square jaws so rods 26 :of the drum may sprocket the drum and if desired the longitudinal tie be extended through the. sprocket wheel 25 'and' provided with nuts 27 which seat against the outer face .ofthe" sprocket. wheel and secure It should be underthe drum.
that these tie rods 26 do not any driving wheel is keyed to through the shaft drives the drum. Thespr'ocketwheel 23 is driven through that it will not release automatically once it has been closed.
"The clutch member'29 may be closed at lever 30 at the left or floor' 31, which operates a horizontal link 35, the fork of which connects with the movmembers and when posts 3 and): and carry able clutch member:
The shaft 6 -is driven This lever is fulcrumed at 36 an the spring. 37 is attached to it and normally. holds'the clutch open.
continuously by means of a chain. driven by an engine and running over the sprocket keyed to the shaft.
The ends of the shaft 6 project beyond the the usual continuously driven nigger heads 46.
With the organization of parts described above it w'rlhbe evident that the chains 8 and 15 will be continuously driven but if the,
two clutches 10 and 12 are open the sprocket wheels 9 and 13 will'rotate idly on the drum shaft. By' 'cIOSing'either of these clutches the drum ma befdriven at lowv or intermedlate spee er .21 illustrated -on the clutch 12; and'an inclined or beveled face 22:
described more fully herean alining driven mem -r' of asprocket wheel 25. Th s wheel is keyed to theshaft 1 withbecause the h fl by placing the sprocket'wheel-25 between.
the post 5 and the adjacent end of the drum which is constructed or sleeves 44 at of the clutch 40 is splined chain 24 thendrivesl:
When it desiredfto drive the drum the two clutches 10 and. 12 are the drum through the sprocket wheel 25.
1 It will-be evident that if the high speed clutch 28"should no harm will be reason of the beveled faces 22 of the clutches be closed while the clutch I 10 or the" clutch 12 is in a closed condition,- done to the mechanism by 10 and 12; the result lwouldmerely be that I the shaft 1 would commence ables such a two-speed drive to be readily transformed into a three-speed drive simply and atthe same time placing a'correspondingsprocket wheel and clutch on the drivin it should be understoo drivethe clutch posts 4 and 5 shaft 6. ,I-HOWGVBI, that with such a two-speed which is locatedbetween the to rotateyat a higher speed and this would throw open low speed clutch or the interme is a square jaw clutch,'and for'this reason it is necessary to move such clutch up onto the shaft 6 to drive the new sprocket wheel 23, and to substitute a'beveled jaw clutch 12 between the postsA: and 5, as the driving connection at this point will now become an intermediate speed and mustbeconstructed so as to throw out automatically in case the third or high speed is thrown in without throwing out the intermediate speed.
Where a two speed rotary draw worksis transformed in this way the shaft 6 will have a key slot just to the left of the post 5 at square jawwhich the loose sprocket wheel 23 must be placed. As the slot in the shaft at this point isa disadvantage, we provide bushin -s this point which provide continuous cylindrical surfaces or hearing contacts for the hub of the sprocket wheel. It is understood that the embodiment of the invention described herein is only one of the many embodiments this invention may take and we do not wish to be limited in the practice of our invention nor in our claims to the particular embodiment set forth;
\Vhat we claim is: 1. In a rotary drawworks mechanism; the combination of a frame having end posts and an intermediate post, a drum-shaft, a
the drum shaft, a driving connection and its another speed located between the interme.
diate post and the other end post and a third speed driving connection inchi di'ng a driven sprocket on the drum-shaft between the intermediate post and the adjacent end of the drum and a drive sprocket aligned relative thereto on the drive shaft. and a clutch on the drive shaft for said drive sprocket.
' 2. In a rotary drawworks mechanism, the combination of a frame having end posts and an intermediate post, a drum-shaft, a drum carried thereby with one end disposed adjacent to the intermediate post, a driveshaft mounted on the frame parallel with the drum-shaft, a low speed drlving connection and its clutch located between one end of the drum and one of said end posts, an intermediate speed driving connection and its clutch located between the intermediate post and the other end post, and a high speed driviii'g connection including a driven sprocket on the drum-shaft between the intermediate post andthe adjacent -end of the drum and a drive sprocket aligned relative thereto on the drive shaft, and a clutch on the drive shaft for said drive sprocket.
