It is Well known that a fin or tube type ot radiator in which the tins are crimped or i'ormed into different shapes possesses a number oi ladvantages over a. similar type ot rmiliator in which the tins are straighnbut the assembling' or" radiators with crimped tins has caused considerable difficulties7 particularly when the adjacent tins ot' the radiator are not provided with interlitting surfaces, but Contact only at points or lines ot contact.l and t-he formation et inter-fitting si'irtaces is undesirable since this reduces the radiating capacity of the tins. The apparatus embodying thisinif'ention may be used equally Well in connection with the assembling ot radiator cores in which the fins are formed or crimped in such a manner that they contact only along points or lines ot contact. or in connection With the assembling of radiator cores in which the tins are of other construction or form.

The apparatus embodying my invention is so constructed that the fins required for a radiator core ot' a certain size are placed in Correct"` relation tov each other so that the holes tor the tubes oit the radiator are alined, and the apparatus also supports the tins in such a manner that the tubes may be inserted endivise through the holes in the tins while tl'iey are held on the apparatus. The apparatus is preferably also so constructed. that. the radiator core when completely assembled is released from Some of the guide or positioning means tor the tins, so that the assembled cores can easily be removed Yfrom the apparatus. In the particular construction shown I provide a support which may be in the form of a plate or platform against which the edges oit the .tins may rest for alin- LII ing either the front or rear edges of the fins of a radiator core, and a plurality of guide members which the faces of the fins engage for holding the fins in their correct relation to each other while the fins are positioned on the apparatus and while the tubes are inserted through the holes in the fins. The support for alining the edges of the fins may, if the apparatus is used inA connection with formed or crimped fins, be provided with parts engaging with the crimps or contour of the fins. Since these crimps or contours are in fixed relation to the holes in the fins, these parts serve to aline the holes in the fins.

In the apparatus illustrated the support or platform is movable to .strip the assembled core from the guide members.

In the particular embodiment of the invention illustrated the frame of the apparatus includes a fixed top platel A which may be suitably'supported in any desired mar.- ner, for example bv means of upright legs or supports a, and the fixed top plate or member A is provided at its edge portion with downwardly extending flanges a to which the legs a are secured. The guide members for use in positioning and spacing the radiator fins relatively to each other are secured to the top frame member A, these guide members in the particular form illustrated being a series of upright pins or posts B having' enlarged heads at their lower ends and being secured in holes in the fixed plate A, for example by a drive fit. C represents the plate, platform or support on which the edges of the fins of the core rest during the assemblingl of the core, and this support is provided with holes or openings through which the upright guide members or pins B pass. The guide pins or posts B are arranged in rows extending both longi tudinally and transversely of the apparatus, the radiator fins being positioned between transverse rows of guide pins and the tubes being' passed through the alined holes in the fins between longitudinal rows of guide pins. The En supporting plate C is movable vertically, in the particular construction shown, relatively to the upright pins or guide meinbers Al?) so that the assembled or finished radiator core can be readily moved out of engagement withv the pins or guide members B.

Any suitable or desired means maybe used for moving' the support or platform C relatively to the pins to strip the assembled core from the pins or posts B it being obvious that many different devices could be used for producing' this relative movement. In the construction shown.y the support or platform C is slidably mounted on the frame of the apparatus by means of a plurality of upright slide rods or bars l5 secured to the support C and guided in suitable bearing lugs 16 in the top plate A of the apparatus,

side flanges a of the top plate or member A.

Two shafts 2O are shown, each of which is provided with two pinions ISL and means of any suitable kind may be provided for simultaneously turning the two shafts 2Ol so that all of the four gui de rods l5 of the movable support C may be raised and lowered'v simultaneously. For this purpose one or two sprocket chains may be employed which mesh with sprockets QG mounted on the shafts 20, so that rotary motion on either shaft is transmitted to the other shaft in the same direction. Either one of the two shafts may be turned by means of crank or handle Q7 secured on one of the shafts and adapted to be turned by hand for imparting rotation to the sluifls.r and vertical movement to the slide rods or racks 1.5.

The crank or handle 27 is preferably pro vided with an arm 28 provided at its end with a spring pressed. latch or bolt see Fig. 3, adapted to engage in a hole or recess 30 formed in one of the side walls or flanges d of the stationary top plate A, a spring 3l normally holding' the holt 29 in its locking position in the hole 30, as shown in Figs. 2 and 3. 32 represents a knob or enlargement of the bolt 2f) by means of which the bolt may be pulled by hand against the action of the spring 3l to permit the crank 27 to be turned. The object of the incl-:ing bolt is to hold the fin supporting' plate or platform C in its upper position while the core is being renuived` the plate C ren'iaining normal-ly in its lowered position by gravity, as shown in Fig, l. This lockingdei'ice for the c 'ank or handle 27 may be entirely omitted or replaced by auv other suitable type of locking' or holding' device.

The pins or guide members B muv he of any suitable or desired shape, depending entirely upon the nature of the Vins .of the ra'- diator core in connection with which this apparatus is to be used)` and a larger or smaller number of guide members or pins may be employed depending upon the number of radiating fins to he used in a core. In the particular construction shownn the apparatus is intended to be used in connection with ns such as illustrated in El to l2. which fins D are formed` or crimped so that the front edges thereof forni diamondshaped openings through which the air enters into the radiator core. For this purpose the front edge f7 of each pin is. of anguv lar zig-zag form as shown in Fig. .l2 and the l D fl fins are so assembled that the points or angles of the edges of one tin lie against or approximately meet the points or angles ot an adjacent tin to form the diamond shaped air inlet passages in the radiatm', and in the particular construction shown the rear edges d of these fins are substantially straight. Parts of the intermediate portions Z2 of the radiatorfins are bent approximately into the same plane as the straight back edges thereot so as to engage the sides of the pins or guide members B. T he radiator tins are also provided with the usual holes (.73 through which the water tubes E of the radiator extend. A radiator of this kind described in my Patent No. 1,014,816but it will be understood that the apparatus may be used in connection with radiators having: tins of many different forms or construction, and the holes d for the water tubes may be either round as shown, or in case tubes ot elongated cross section are used. the holes d should correspond to the shape of the water tubes.

In case a 4radiator assembly apparatus is used in connection with straight or hat fins, the pins or' guide rods B may be placed closer together so that only one lin may be inserted between each pair ot rods or eui de members B, and in such a case the holes in the tins can easilybe alined by aliningr the sides of the `fin by any suitable straight edge or surface. However, if the t'ront edgesv of the radiator fins are formed or crimped to produce air passages at the front of the radiator of such shapes as diamonds, squares. hexagone or others, a pair ot is placed between each transverse row ot guide pins or devices B, and other means are provided for correctly positioning the fins relatively to each other so as to aline the holes therein. ln the particular 'form shown a plurality of comparatively short studs F are provided on the support or platitorm C, whichare so arranged that the studs tit into the bent front edges of the tins and thus assure the correctV alining ot adjacent tins, the upperends of the studs F beine' preterably tapered so that. the edges of the tins .will readily slide into their correctpositions. These studs are arranged in rows extending,- both transversely and longitudinally oin the support C and these rows are arranged be-V tween the rows of guide members or posts B. The .studs or projections F are comparatively short and are below the holes in the tins that the studs do not interfere with the placing of the tubes into the holes in the fins.

In the use of the apparatus described. the tins D are placed into their correct positions between the upright posts -or guide members B; two tins of the construction shown being placed between each post and the tins beine; oppositely arranged to Jform air passages between adjacent fnsl The tins are preferably placed on the apparatus with their front faces downwardly, so that the front zig-Zag edges of the tins will cooperate with the studs F to correctly position the fins as shown in Figs. 8 and 9 and to aline the holes therein. After the required number ot tins hare been so positioned on the apparatus, the holes d3 thereol will all be alined so that the tubes E can be inserted endwise through the fins, this beingdone either by hand or by some implen'icnttor forcing a group of tubes in the direction of their length through the alined holes (Z3. It' the tubes are placed into the tins by hand, ay spacing' plate G, Fig. el, is preferably em ployed which may be placed between two transverse rows ot' guide posts or pins B and against which the ends ot the tubes E may abut to stop the further moiv'ein-ent of the tubes through the tins. A'lter all the tubes have been placed into their operative positions in the tins. thc crank 27 Vis released by drawing out the knob 3Q and disengaging;` the bolt '52.9. whereupon the two shafts 20 are turned by means of the crank 2T, thus causingthe tour sli( e rods Yl5 and the moyable support C to be `aised to strip the assembled core trom the posts or ,guide members B. VUpon returning the crank 27 to its origiiial position, the ai'iparatus is ready tor the assembling of another core. It will be understood that during; the vertical movement of the edge supporting platform or member C. the upright guide posts or members l slide through the holes in the menr ber (l. Fie'. (i shows the position ot the parts when the edge supportithe` platform or member C is in its upper posit-ion in which position the core is ready to be lifted from the apparatus.
