The water jacket 1, which constitutes the casing and also the 'main outer member of my improved rai'liator. in the form of my invtmtion shown in Figs. 1, '2 and 3, cone prises an upper water chamber 2, water legs 5). which depend from the chamber 2', at the I sides of thewater jacket, and a lower water chamber l.

The upper ends of the water legs 3 connnumeate directly with the upper water chamberfl. The lower water chamber 4 is disconnected and spaced from the water legsJ-l. The inner vertical walls 5 of the water legs 3 other. The lowerwall (S of the lower water chamber is horizontal. The upper wall 6 are parallel with eael'r of said (.ihamber is also horizontal and is 1 parallel with the lower wall of the upper water ehan'ibe'r 2. The lower wall?- ofthe upper water chamber 2, is here shown as crowned or arched. Thesaid- Water eliann bers and water legs have a common front wall '8. Said water chambers also have a eormnon rear wall 9. The inner side walls 5 of the. water legs 3, merge into tlie bot'ttom wall? of the upper chamber 2, and the up per all 10 of said chamber-2 which is crowned or arched, merges into the outer walls 11 of the water legs 3, and is provided atv its (:enter with air-opening 1.2, and an-upwardly ext-ending circular flange 13 around the said openings. The said walls 11 are.

provided with outwardly extending lugs 14 which serve to support the radiator, An opening 15 extends through the water jacket from front to rear and forms a cam nected to the bottom and end walls of the reinforcing bead or flange 17, which extends around the same and also forms an ornament for the front of the water jacket. The outer walls 11 of the water legs 3, are con lower chamber 4, by curved walls 18, which form the lower corners of the water jacket and close the outer sides of the spaces or chamber 19' between the water legs 3, and the lower water chamber 4. Reinforcing webs 20 also connect the opposing ends of the water legs and the lower water chamber and extend from the frontside to the rear side of the water jacket. At the center of the rear 'wall ofthe upper chamber 2 is a water inlet opening 21, through which the heated water from the water jacket of the engine cylinders passes to the said chamber 2, and the lower water chamber 4 has in one side of its rear wall an opening 22'through which the water cooled in and by the radiator, passes back to the water jacket of the engine'cylinders- The said lower chamber 4 of the water jacket 1, is also provided in its upper side at its center, with an opening 23 which is provided in-its upper side with a counter-bore 24, whereby an annular supporting flange or shoulder 25 is formed around the said opening 23. A flange 26 extends rearwardly from the outer side walls, and the top wall of the water jacket, the said flange being provided atsuitable distances apart with openings 27. This water jacket which is also the outer and incasing member of my improved radiator is a single seamless casting, which may be readily manufactured at minimum cost, and is not liable to be injured by the vibration and mot-ion of the car in which the radiator is used.

In connection with the water jacket or outer ihcasing member of my improved radiator, I also provide a series of removable radiator sections 28 which are disposed one above another, and are placed in the chamber 15 of the water jacket 1. Each of the said sections 28 comprises a pair of header or end chambers 29, a center chamber 30, and a series of water tubes 31, connecting the said chambers together. -Each chamber of each of the sections is a casting which may be readily and very cheaply produced. The rear wallsof the water legs 3 are provided with openings 32 and with counter-sinks 33, the rear sides thereof forming flanges or shoulders 34, around the said openings. Each header or end chamber 29 of each detachable radiator section lS p1O\'1dQd on its front side with an opening 35 coincident with the opening 35 and on the rear side of which is a counter-bore 39 forming an annular shoulder or flange 40 around the said opening 38. The header or'end chambers of the detachable radiator sections are socured in place on the rear sides of the water legs, and against the inner sides of the outer walls 11 of the water jacket 1, by means of bolts 41 which pass through the

openings

38, 35 and 32 and engage threaded openings 42 in bosses 43 which are formed on the inner side of the front wall 8, and the heads 44 of which engage the counter-bores 39, suitable packing rings or gaskets 45 .being placed in the said counter-bores and bearing between the heads of 'the said bolts and the flanges or shoulders 40. The central chamber 30 of each detachable section is provided in its lower side with an opening 46, around'which is a depending annular flange 47. Each of the said chambers ex-' cept-ing that of the uppermost detachable radiating section is also provided in its upper side with an opening 48 which is concentric with the opening 46,,and in the upper side of which is a counter-bore 49, providing an annular flange or shoulder 50 around he said opening 48. The central chamber of the lowermost section bears on the upper side of the chamber 4, is disposed with its flange 47 in the counter-bore 24 of the opening 23,"a packing gasket 51 bearing between the flange 25. and the said flange 47, and effecting a water tight joint between. the chamber 4 and the center chamber of the lowermost section. The flange 47 of the central chamber of each of the other detachable sections 28 is disposed in the counterbore 49 of the next lower section so that all of the detachable sections are arranged in superposed relation and in communication with each other, and with the lower-chamber 4 of the water jacket 1, a packing ring or gland 52 of suitable material being disposed between the flange 50 of each section 28, and the flange 49 of the section thereon, so that water tight joints are effected between all of the said detachable. sections. Each of these joints comprises as will be noted, a counter-bore in one part, and an annular flange in the adjoini g part, disposed in the counter-bore, an a gasket in the counter-bore between the bottom thereof and the annular flange. Hence the gasket is surrounded on its outer sideby the counter bore and is compressed between the bottom of. the counter-bore and the flange so that there is no possibility of the gasket working jloose or getting out of its seat, and 'hencethe joints between the parts arerendered perfectly water tight. and prevented from.

being injured by the vibration occasioned by the motion oi. the car and of the engine. and leakage at'the joints between the parts of my improved radiator is prevented.

A bolt 53 extends through the openings which effect eomnumication between the cenlral chamliiers of the detachable sections 28, and the lower section at, of the water jacket, the head of the said bolt being seated in a counter-bore 54: in the bottom of the said chamber 4, and the upper threaded endof the bolt being engaged with a threaded opening in a boss which is formed with and depends from the upper side of the cen tral chamber of thenppermost' detachable section 8." A suitable packing gland or ring 56 bears between the head of the said bolt and the bottom of the bore 54, in which the same islocated, the counterbore forming a seat for the gland or ring, entirely sur-' roundin thesame and preventing the gland or ring trom working loose.

It will be understood from the foregoing that by first removing the bolt 53, and appropriate bolts bolts 41, anyone of the de- ..tachable. radiator sections may be removed from the chamber 15 in the Water jacket. .1, for the purposes of repair, or substitution. and hence in the event that any portion of the radiator wears out, or becomes broken,

the same may be very readily repaired at very small expense and in a short time, and hence. without the necessity of putting the automobile on which the same is used, out OfQOHIIHiSSlOIl for a considerable period of time, while repairs are being etl'eeted.

'It will be observed upon reference to the drawings, that the detachable radiator sections almost entirely fill the, chamber 15, there being a space left between the uppermost detachablesection and the top of the water jacket to permit of the slight vertical movement required to disconnect any one of the radiator sections from the one next below or from the bottom chamber 4.

it will be observed that by the provision oi. the lower water chamber tot the water acket, and byplaci'ng the detachable radiator-sections on the upper wall of said lower water-chamber, the weight of the radiator sections is imposed upon the bottom or lower water chamber of the water jacket, and hence the bolts 4l'and 53 are relieved of the weight of the radiator sectionsand are only required to securely hold the radiator sections together, and to also securely connect them to the water jacket.

' By the construction of; my improved water jacket as hereinbefore described, and arranging the radiator sections to be placed in the chamber 15, from the rear side thereof the finish of the front of the water jacket is not affected and remains the same Whether the radiator sections be in place or removed. Moreover, it will be understood. that the water legs .forln lateral arms in the water jacket which extend inwardly from the sides of the water jacket and that the end chambers .or headers of the radiator sections are immediately in rear of the said lat eral arms of the water jacket, so that their front ends are covered and hidden by said lateral arms of the ,water jacket, and more over, the end chambers of the radiator sections are thus disposed entirely out ofthe opening 15 which'eonstitutes the radiating space. j j

By making my .water jacket integral as a seamless casting, and providing it with a lower water chamber, to form a supportt'or the radiator sections, my improved rad-iator is made exceedingly strong and durable. There being no seams in the water jacket there is no liability of the same becoming leaky, there is no possibility of seams being opened by vibration, of the car, or

motor, and hence repairs of the water jacket are never required. Moreover, the water jacket being integral and constituting a single casting is practically inflexible, and

there is no danger of opening joints be-- tween the same, and the radiator sections connected thereto, and secured therein. Moreover, bymy construction of my water acket with the upper and lower water chamber,.tand the side walls which abut directly against, the sides and ends ofjthe detachable radiator sections, the radiatmsections are securely 1ncased In and protected by the water jacket.

Each detachable radiator section :28 is providcd with a series of radiating plates 57 which in practice are made of sheet copper or other suitable material. The said plates are in this form of the invention vertically disposed and are provided with opcnings'fih through which the pipes I'll extemhsodh'at- The sleeves and the plates are not soldered The ends ofthe pipes whlch pro ect beyond the outerto the pipes'or to one another.

most plates and sleeves are fitted .in openings in the opposing walls of the chambers of the sections, and soldered or sweatcd thereto, and the sleeves and radiating plates are clamped together and on the pipes by the chambers of the radiating I sections,

v by a nipple (37 which lower chambered header (35 is Since my radiating plates and spacing sleeves are unsoldered, it will be nnderstoo that they may be readily detached from the pipes, after first detaching the ends of the pipes from one of the sections of the radiator, and hence should any radiator plate become injured it may be readily removed from the pipes, and repaired or replaced. I

In the form of my invention shown in Figs. 5 and 6, the water jacket 1 is provided with an upper water chamber 2, a lower water chamber 4:, and vertical parallel sides which connect said water chambers together. The lower Wall of the upper water chamber and the upper all of the lower water chamber are parallel. From the lower side of the upper water chamber '2, at the front end thereof, depends a vertical 60 which forms a lateral oif-set from the said upper water chamber, which otfset extends across one side of the radiating chamber or opening 15 and at the front of the said chamber, and at the front of the water jacket, the said opening 15 being formed in the water jacket between its upper and lower water chambers. and its vertical side walls. The lower water chamber 4..is provided on its upper side at its front end with a chainbered arm 62, which also forms a lateral offset which extends across one side of the radiating chamber at the front end thereof. The front of the water jacket in this form also of my invention. is finished and is not affected in appearance by thedetachable radiator sections, which are inserted in or removed from the air chamber or 'adiating chamber 15,.through the rear side of the said chamber. Each of the detachable radiator sections 63 in this form of my invention comprises an upper chambered header Get, a lower chambered header G5, and a series of vertically disposed water pipes (36, the ends of which are secured in openinngs in the said chambered headers. so that the said water pipes connect the chambered headers together. lCach header 6+ is provided at its front end with. an opening titi surrounded fits in a counter-sunk enlargement of an opening 68 in the rear wall'of the arm 60 of the water chamber 2. Packing rings or gaskets (39 of suitable construction are placed in the joints between the said nipples and the said counter-sunk enlargements to prevent leakage. Each also provided at its front end with an opening 70. and a nipple 71 around the same which tits in a counter-bore enlargement 72 of an opening 73 in the rear wall of the arm 62 of the lower water chamber t, so that a joint is etleeted between each lower chambered headeand thesaid lower water chamber at, packing rings or glands H of suit-able construction being placed in the said joints to prevent leakage. Hence communication is estabchambered arm lished betweeneach lower chambered lieader of each detachable radiator section, and the lower water chamber 4; The said detachable radiator sections are secured in place in the central chamber 15 of the water jacket by means of bolts '75 which extend longitudinally through the chambered headers and throughthe openings between them, and the upper and lower water chambers of the water jacket, the said bolts being engaged with threaded, openings in bosses 76,

77, with which the front walls of the upper and lower water chambers are res ectively provided, the heads of the said bots hearing against the rear sides of the said chambered headers, packing rings or glands 78 which are placed in counter-sinks in chambered headers. In this form of'my invention also, it will'be understood the lower and: also against suitablev the rear sides. of said chambered headers of the radiator sections bear directly on the upper side of the lower water chamber so that the, weight of the radiator sect-ions is imposed upon the lower water chamber of the water jacket, and the bolts 7 5 are relieved of the weight of the" radiator sections and are only required to secure the headers of 'the radiator sections to the lateral off-set arms of the upper and lower water chambers of the water jacket.

The front ends of the headers of the detachable radiator sections are entirely covered by the-lateral otf-set arms of the water chambers of the jacket, and moreover, the headers of the radiator sections are disposed beyond the upper and lower sides of the radiating opening or chamber 15*, so that none of the space of the said opening or chamber is taken up by the headers of the radiator sections. In this form also of my invention, it will be observed that each joint between a header of a radiator section and a water chamber of the watcrjacket comprises a counter-sunk bore in one part. a packing ring or gland seated in and surrounded by said countersunk, bore, and-a nipple or annular flange on the other part so that the ring orgland which is seated in the counter-sunk bore and surroundtul thereby. is compressed between the bottom of the countersunk bore and .the

jacket etlcctually iuca es and ill('l0Si.S the detachable radiator sections and protects the latter. By so constructing myradiator the detachable 'adiator sections are removable. and insertible through the rear side of the radiating chamber or air chamber of i that j which the pipes 66 extend. Tubular sleeves 80 are'placed on the pipes (56 between the plates 79 and serve to space the plates apart.'

The platesand the sleeves which togetherwith the pipes are made of sheet copper or other suitable material, fit closely on the I pipes and are not soldered thereto, but are removable therefrom.- The ends of the pipes are soldered, brazed or sweated in the openings in the opposing walls of the chambered headers. The ou tern' ost sleeves 80 bear against the chambered headers and all the sleeves and radiating plates are held firmly vclampedtogether, andonthe pipes by the chambered headers as will be understood. By first removing the plpes from one of the chambered headers, the radiating plates and the spacing sleeves may be removed from the pipes to permit any of the plates to he repaired or renewed if necessary. The side edges of the plates 79 are bent at substani tially an angle of degreesto form flanges 80. The said flangesot' the radiating plates of each detachable radiator section engage the corresponding flanges of,tl1c*plates of the next adjacent 1 sections. If preferred, vertically disposed plates 81 may be arranged in pairs slightly spaced apart between the plates 79 of the detachable .radiator sections. 0 i

The water inlet opening of the water compartment or chamber 2 of the water jacket or outer casing, is indicated at 21*, the water discharge opening of the bottom or lower water compartment or chamber d. of the jacket is indicated at 22*, andrnear one. end of said chambers an overflow, pipe 81 leads from the upper wa'ter chamber. The overflow pipe, in each form of my invention here shown, comprises curved ,upper section 82, and a lower section 87. The curved section 82 is spaced in the upper water chamber of the water jacket withits upper end extend-- ingup into and opening at the water level opening or nipple 83 at a point above the normal water line in the upper chamber. The lower end of said curved section 82 bears against the rear wall of the upper water chamber and is provided with a sleeve 84 which extends through and is secured in an opening in said will The upper end of thedowersection 87 has a conical union 85 which is seated in a'similarly shapedseat in the rear end ot the upper section 82, and desleeve coupling 86 which is screwed to the,

sleeve84. The lower sect-ion 87 of the overflow pipe is attached to the water jacket at a point on. the rear side of the lower water charge point at one side of the radiator. In the event of an abnormal rise of the water level in the radiator, occasioned by the heating ofthe water or by other cause, the upper end of the overflow pipe will be submerged and the overflow pipe will carry oil the surplus water as will be understood. By thus constructing the overflow pipe of a lower section and an upper section with the latter disposed in the upper water chamber otthe jacket,- and the lower section of the pipe detachably coupled to the lower end of the upper, section thereof, either or both sections of the overflow pipe may be revmoved to enable them to be cleaned or to en able repairs to be effected therein.

The pipes of the detachable radiator sections are differently shaped in the forms of my invention here shown. The pipes 31, in the form of my invention shown in Figs. -1

@110 chamber thereof, and leadsjto a suitable disto 4, are cylindrical and theopenings 58 in the radiating plates on said pipes are cireular.

In the form of my invention shown in Fig. I, the pipes 31*, are oval cross SCtlOlially (as indicated in Fig. 9) so as to present comparatively long upper and lower surfaces the axes of theoval being horizontal, and. the openings 58 in, the radiating plates 57*. are of corresponding shape. This construction of the pipes'tlijf with flattened upper and lower sides incrbases the superficial area of the pipes, correspondingly diminishes the capacity thereof, and hence the said pipes present a greater extent of surface to the cooling action of'the air passing between them and increases-the efficiency of the radiator m lowermg the temperature of the water passing therethrough. The projecting front portions of the plates 57 are provided with alining openings 58", which are oval and through which is inserted a blind'pipe 31", which is similar tothe pipes 31, excepting that its ends, which are open, are not connected to the headers of the detachable radiator sections. The said pipe 31", of each detachablesection serves to brace and strengthen the projecting front portions of the radiating plates. The rear side of the water jacket ,1 is )rovided with a flange 26 which isfidentrwl with the flange 26 shown in the form of illustrated in Figs. 1 to 4. i

In each of the openings of the flange in either form of the invention, is placed the reduced inner end of 'aheaded studSS. The

my invention heads of the said studs lielo'n the outer-side of the said flanges, andthesaid studs are preferably made 0f*'fibe'r, btit may liii'mad'eof any other suitable material. The hood tact. This construction greatly increases the strength of the radiating plates and also improves the appearance of the front air or inlet end of the radiator.

In the operation of my improved radiator, the water circulates through the water chambers of compartments of the Water jacket or casing, and also circulates through the chambered headers, chambers and pipes of the detachable sections. The exterior surfaces of the said pipes are exposed to the air currents which sweep through the central chamber of the outer jacket or casing in which the removable radiator sections are disposed, and hence serve to cool said pipes and the water therein. The air currents also carry off the heat conveyed from the pipe,

and the water therein, by the radiating plates as'will be understood. As above indicated, in the-event of injury to any of the radiator sections or any part thereof, the said injured sections may be removed and either repaired, or replaced by a new one at a comparatively small cost, the said radiator sections being interchangeable. In the form of my invention shown in Figs. 5, 6, any one of the radiator sections may be removed and dispensed with if necessary or desirable as during a long run, without aflectiug the operation of the other removable radiator sec-- tion. Vv'hen any of the radiator sections is removed, the openings in the-arms of the upper and lower chambers of the water jacket or outercasing, uncovered by the renioval of the said detachable section, may be closed by means of the heads 90 of bolts 91, as shown indetail in Fig. 8.

I would have it. understood thatQwhile I have herein shown and described what I now regard as preferred embodiments of my invention, I do not limit myself as to the material of which any one or more of the parts of the same is constructed, nor as to the size or shape of any of the parts as modifications may be made therein within the scope of the appended. claims, and without departing from the spirit of my invention.
