To tlllfwhomz'z Concern:

lie Ait known that l, llonnr B. Woon-` resident of lizittsliixrggh,y in the connty of Allegheny and State of Pennsylvania, have invented certain new and useful improvements in Tug ,'Vlheel-Rims, of whichy the following is a specification.'

' `My invention relatesto the construction of wheel rims, and more particularly the construction of the tng'rims let the bullf wheels and band wheels well 'drilling rigs.v

Une object of this inventionl is to provide a tugrirn ot' novel'eonstrnetion which Vconiforming 4part of v.bines great strength and rigdity'witli a.

minimnnrweight and which is easily constructed and readily assembled and dismembered in the application and use of the rim.

A still further object of the invention is the provision oi' a wheel rim haring the novel details ot' vonstruetion and the ai rangement ot' parts shown in the drawings, more fully described hereinafter, and partirnlarly pointed ont in the appended claim.

Referringr now to the drawings, forming part oi' this si'ieeilieation, Figure l is a plan, partly in seetion, showingr the bull wheel of a well drilling rig having a seetional tup;

rim thereon einbmlyinpg'` the novel features ol' my invention.

Fig. 5 is a transverse seetion,` on a larger sealepshowing details in the ronstruetion 'oi a pressed steel tug wheel rim embodyingr myV invention, the sertion being' taken on the 'l2 and. rivets 1,3 to the rim sections.

l. In the accompanying drawings, the bull wheel and band wheel tu rims'embodying woirrrr, a citizen, of the United States, and

in Fig. .5, is made froiri a7. thin rolled Isteel l plate,l of substantially unitorzn thickness, which is pressed or stamped betweensuit able foi-ming guides so asto forni a transrersely fiat or straight peripheral snrfane 2 and haring integral flanges 3, 3 at theedges 7 0 defining' the width of the tug rin1, the flanges ,25 extending` inwardly, in substantial parallel planes. The rim l shownlis formed of four duplicate"sections or segments, (the number l oi sections being governed ordinarily by the,

diameter of the wheel rim) and eaclisee` d tion is curved I lengthwise to' a predetermined radins inorder to form a rim of the ilesired:"diarneter.` Two parallel encircling,r

` indentations are pressed` into the flat periphery :2 oi the rim 'sections to form rope 2grooves 4 and 5 for the ball ropes used in transinittiinif power from the band wheel to the bull wheel oi a Well drilling rig, and the grooves, 'which may be made semi-Cir- 85 enlar in cross sertion. preferably are formed with flat inwardly converging sides 6, 6 in the manner shown in Fig. 5. u

ln the hull wheel shown in Figs. l to l the ser-,tional tugr rim A is connected by conrerg'ii'igr spokes T to one vend of the tubular bnll 'wheel shaft l, this shaft having a. rnd- The 'gudgeons ave spiders S) whieh fit tightly into the ends of the shaft B and the spiders are provided :it 9b 'one end with a peripheral flange 10 which engages with the end of the bull wheel shaft to assistin locating and maintaining the gadgeons 8. 8in axial alinernent` with the shaft l.' (See Fig. 1..) Rivets 1l are used 4100 to sedare` the gndgeonsto the shaft, although any other approved fastening meansv may be employed.

Each `"section ot' the tugl rim A is provided with two oi the spokes 7, which are shown rigidly fastened at one end by gusset plates The inner ends of the spokes 7, which may b9 convenientlymade of rolled steel .channel beams7 extend between the parallel faces of the annular legs of the two flanges 14, 14, the flanges 14 being riveted to the shaft B,

vand bolts 15 `beingemployed to detachably fasten the spokes 7 to the flanges 14. The abutting ends of the rim section are detachably connected by splice plates 16 on the marginal anges 3, 8 thereof, which are fastened by rivets 17 to theflanges 3, 3 at one end of the rim sectionand which are secui'ed by bolts 18 to -tlie flanges 3, 3 at rim sections, the helpers which also eX- tend outwardly being riveted to the Spokes 7 of the tug rim. The helpers 20, 21, and `22 are positioned 'at successively greater distances from the periphery of the rimiA,'.the

dog and helpers being employed to assist in shifting the bull ropes in removingv and replacing these ropes onthe tug rim A of,

the bull wheel, as is frequently necessary in the operation of the bull Wheel.

That portion of the bull Wheel shaft B adjacent to the tug wheel is employed to store unused portions of the' well drilling cable and in order to provide sufficient storage capacity, a spool Ci is adjustably secured on the shaft, the spool being arranged to move toward and away from the tug rinil A. As shown, the arms of this spool are formed of rolled steel channels Q3 which are detachably connected to one another by suitable bolts 24 and which have a clamp .25

thereon by which the spool is frictionally held in adjusted position on the shaft.

The spool side of the tug rini A is provided With a series of turning pins 28 which are conveniently formed in this case of a short piece of wrought metal pipe and a bolt 29 which extends through the pipe and through suitable holes in the flanges 3 of the tug rim. The turning pins 28 are employed to rotate the bull wheel manually in renioving and replacing the bull ropelon the tug rim A i-n the usual and well known manner.

Secured on the turning pin side of the tug', wheel. is a series of cable protectors 30 having inwardly -bent ends, these 'protectors being made. of flat bars and being riveted to one end of the Z-sliaped knees 31, the other end of the knees'being detachably fastened to the spokes 7 by bolts 32. The edges of the cable protectors 30 are rounded to prevent cutting or fraying of the drillingl cable in Winding and univinding the cableon the shaft B, these protectors being provided on' alternate spokes 7 to prevent the drilling cable from fouling on the tug rim turning pins 28. L

1 it is supported in suitable bearings, the shaft rims to all metal wheels.

The bull wheel shaft B is also provided at one end with the usual brake wheel l), u which, as shown, is made in sections; and has a laminated wooden brake riui formed of wooden cants QG which are fastened to lthe outer ends of spokes Q7, the spokes being dctachably secured to the shaft B in the same manner as the spokes of the tug rini The :brake wheel also has cable protectors 3l() which are fastened on the spool side ofl the r bull Wheel in the `saine n'ianner as on the tu g i'ini and turning pins '29 which aril niadc of Wood,.are tightly driven in holes of suitable size in the gndgeon side of the brake wheel to provide means for manually turning the bull Wheel froin the brake wheel cud of the bull Wheel shaft. The brake wheel D, not forming part ofthis invention, its construction is not further desciibed.I

. In the band wheel construction shown in Figs. 6 and 7, the band wheel E is built up solidly of a series of boards or planks 35i so as to make a laminated wooden wheel. This Wheel is provided with a shaft 34 by which being keyed to the . i'netal hubs 35, 35 of which there'is one on each side of the web Q theiwheel'E, and the hubs are fastened lily through bolts 3G to the web of the wheel itself is an' old and well known construction. Secured on one. side of the band wheel lil so as to be concentric with the periphery of this wheel,v is a sectional nietal tug iiin A embodying the novel features of my invention. This tug rim is essentially the saine as has been described in eonnection'ivith Figs.y 1 to 5. In the case ofthe band wheel E there are no spokes, however, connecting the rini to the shaft for the wheel, and a series of brackets 37 and 38 are employed in fastening the tug rim A to the side of the wooden band wheel E. (See Figs. 6 and 7 l Similar brackets may be used to fasten these As shown, the brackets 37 are formed of short pieces of rolled steel channel bea-nis, one flange of the beams being provided with holes through which the bolts 36 extend in fastening the rim sections to the band wheel, 115

the bolts 3G, of which there'are two for each bracket, also extending through registering holes in the webof the band wheel E. A

l bracket 37 is provided on one end, and a sec- .ond bracket 38 at an intermediate point in 120 the length of each section of the tug riin A,

,these brackets being fastened by rivets to -the flanges 3 of the rim sections.

The brackets 37 at the ends of the riin sections have a short 4piece ofchannel beam 40 125 riveted thereto, the two pieces of channel beain 37, 40 being placed back to back so that the flanges of the shorter `section will proieet outwardly and these outwardly pro- Vfooting flanges are provided with holes 130 This wooden band wheel construction In 9 which register with similnrholes in one end Dit the langes 3 of the rim sections. Bolts 41 which 'extend through these registering holes detnohzibly fasten the abutting ends of 5 the rim. sections to one another.

The bull Wheels and band Wheels equipped 'with my improiied tug rim will be 'operated in itlieusuzil and wel] known manner.

The advantages of my .invention will be l oli 'ppnrent to those skilled in the art. My iinpl'oved pressed'steel tug rim provides a deineligible riin which` easily and quickly erected :ind disinemlierefil and' trzinsporteiil 'from place to place.
