AUTOMOBILE-RADIAT R.

Application filed December 26, 1918.

; being had to the accompanying drawings,

forming a part hereof.

The present invention is directed to improvements in automobileradiators, the special object sought being to construct a radiator provided with a removable core which may be of any standard type and kept in stock, said core being made attachable to and detachable from, a radiator tank section or frame permanently mounted on the car As radiators are now generally constructed.

, the core and tank section or frame are practically integral, and when occasion arises ,for the driver to work on the engine the entire radiator must be taken off to make room for the operator and permit access to the engine, Again, the provision of a detachable core makes it comparatively easy --to repair leaks-and make any other necessary repairs to either the outer frame or the core. \Vhere the core is of the cellular or tubular type the cells or tubes preferably terminate in hollow heads which may be readily coupledto or uncoupled from the tanks oft-he radiator frame or outer section,

and this without entailing any material loss ofthe water usually employed as the circulating cooling medium, and which often can not well be spared. The advantages of the invention will be fully apparent from the following detailed description in connection with the accompanying drawings in which- L Figure 1 represents a iront elevation of the impro ed radiator; Fig. '2 is a side elevationthereof; Fig. 3 is a vertical middle. section on the line 3-3 of Fig. 1; Fig. t is an enlarged horizontal section through-the upper head of the core on the line 4-4 oi ,Fi r. 1 a art bein broken away Fig. 5 is a horizontal sectional detaii through the upper tank of the outer frainc on the line 5-43 oi :lf'ig. 1; and Fig. 6 is a vertical. transverse sectional detail on the line 6 6 of Fig.1.

.Referring to the i'lrawings, 1 represents 'an outer frantic provided with upper and lower terminal hollow conunirtnienis or Specification of Letters Patent.

tanks 15 and t respectively, the upper tank serving as the intake and the lower tank as the discharge for the circulating cooling medium (water), the rear wall of the tank t being tapped by the teed or supply pipe '2 and the corresponding wall of the tank If being tapped by the discharge pipe 3 leading from the engine as well understood in the art. The bottom wall in of the tank 6 and the upper wall w of the tank t are made sloping, the same converging rearwardly as shown (Fig. 3) to facilitate the mounting of. the detachable core of the radiator. The core-body C is herein shown as of the conventional cellular type, the opposite open terminals of the circulating cells being provided with the usual slotted plates 4, the slots s whereof terminate near the opposite. edges of the plates, e marginal imperforate portions of the plates bearing against the ledges or slwulders a formed respectively on the inner walls of the upper and lower hollow circulating heads 5 and 5 terminating the core-body and coininunicating with the passage-ways or cells thereof through the slits s as well understood .in the art. The top and bottom walls of the core heads 5, 5', respectively are made sloping to conform to the pitch of the walls in, an, of the tanks f, t, the front walls of the said hcads having i'ornicd integrally therewith the hollow bcnds or goose necks 6, 6, respectively, the free uppcr'or intake terminal of the bond 6 bcing inscrtible into an opening in the .l'ront wall oi the tank I, and the free lower discharge terminal of the bond (3 being inscrtible into a corresponding opcniiv of the front wall oi the tank t, the inner laces of said front walls on cithcr side of the openings receiving the tree terminals oi" the bcnds or goosonocks, being formed with hollow bosses in for receiving the screw studs 7, the said studs being drivcn into the bosses with a tight iii the studs 7 are scicw-threaded, the threaded portions being freely passed throu h openings in die side lobes or checks formed integrally with the circulating bonds or goosenocks (5, G.

Disposed on opposite sides of the center oi: each head 5, 5, of the core are pockets or depressions [L which receive pads or blocks 8 a shock absorber; and being yielding, it fa- The outer ends of cilitates the insertion'of the core body and its heads into the outer frame 1. \Vhen the parts are assembled, suitable blind nuts 12 passed over the outer threaded ends of the studs 7 clamp the core to the outer frame, it being understood that the core herein includes the core-body C and its heads 5, 5, and as shown constitutes the removable or detachable unit of the radiator. The outer faces of the shock absorbers 8 (four being shown in the present example, though I am not to'be restricted to any special number) engage the sloping walls w, w, of the tanks 25, t, of theouter frame and take up any shocks incident to the travel of the vehicle. Between the lobes d and the outer faces of the tanks t, t, are preferably interposed suitable packing strips or gaskets 9 to prevent leakage, the gaskets being of course formed with openings registering with the bores of the bends 6, 6, (Fig. '3).

\Vhenever it becomes necessary to detacl the core for any purpose, all that the driver need do is to unscrew the nuts a (four of them) when the entire unit C, 5, 5-, including the pads 8, S, and goosenecks 6, 6, slips off the studs 7 (see dotted position in Fig. 3) the open frame 1 affording access to the working parts of the engine. To restore'the core, the same is reinserted into the'frame, the parts so fitting that while the core is being inserted, the openings in the lobes (Z will register or come opposite the' studs 7, the latter passing freely through the openings, after which the nuts n are placed back on the studs clamping the parts together and the radiator is again ready for service. To prevent loss of any material quantity of water as the core is being detached, the bottom hole of the frame or that formed in the tank t to receive'the free end of the bend 6' may be plugged up with a cork or block of wood or anything handy. It is of course rare that the loss of the water can cause serious inconvenience, water being usually obtainable on the road. In the present embodiment of my invention the ledge r by which the forward end of the hood H is supported is formed on the frame 1. In the present embodiment of my invention I provide pockets or depressions h for preventing displacement of the pads or shock absorbers 8 but obviously I am not to be restricted to this specific construction. So too, any equivalents of the construction here shown for establishing circulation between the core and the frame tanks are contemplated by the present invention. Features shown but 1.. In a radiator, an outer frame provided 1 with water circulating compartments or.-

tanks, a detachable core inserted in and extendlng the width of the frame, water c1rculatlng connect1ons between the coreand not alluded to are well known in the art and compartments, and suitable shock absorbing devices between the core and frame.

2. In a radiator, an outer frame provided with top and bottom tanks,a core comprising a body terminating in top and bottom hollow heads extending substantially the width of the frame and insertible into said frame, the bottom and top walls of the top and bottom tanks respectively being made sloping and converging rearwardly, and the corresponding walls of the heads of the core being pitched to conform to the sloping walls of the tanks, means for establishing circulation between the frame tanks and core'heads through the front walls of the tanks and heads r spectively, pockets disposed on the sloping 'alls of the core heads, suitable shock absorbing elements mounted in said pockets and engaging the sloping walls of the tanks aforesaid, inlet means for the circulating cooling medium formed in the rear Wall of the top tank, and outlet means in the corresponding wall of the bottom tank. I

3. In a radiator, an outer frame provided with top and bottom tanks, the bottom and top walls respectively of which slope and converge rearwardly, a core compr' ing a body terminating in top and bottom hollow heads insertible in said frame, the heads having sloping and converging walls to conform to and engage the corresponding-slopaforesaid, and means for establishingcirculation between the frame tanks and core heads through the front walls of the tanks and heads respectively.

In testimony whereof Iaffix my signature in presence of two witnesses.
