SPECIFICATION forming' part 0f Letters :Patent N0. 681,196, dated August 27, 1901. Application filed November 5, 1900. Serial No. 35.459. (No modeld t ToalZ whom t may concern:
Be it known that I, ERVING I). CLARK, a citi cuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Tubular Metallic Frames,
of which the following, taken in connection with the accompanying drawings, is a full,
y y clear, and exact description. n j lo1 The object of this invention is to more se- 1 curely and permanently unite in their requij site relative positions the members of a med tallic tubular frame, more especially members of bicycle-frames or other vehicle-frames :and to that end the invention consists in the novel means for uniting said members, as hereinafter described, and set forth in the `claims.
In the accompanying drawings, Figures l `and 2 are vertical longitudinal sections of two frame members united by my invention and showing said invention embodied in the j so-called iiush joint and lap-joint of said members. Fig. 3 is a fragmentary side `view of the connection of the crank-hanger tube of a bicycle-frame. longitudinal section of said part of the frame,
Fig. Il is a vertical and Fig. 5 is a vertical transverse section on line X X in Fig.v 3. y
Referring to Figs. l and 2, a and b designate two steel tubes or tubular frame members disposed with one to extend laterally y from the side of the other. 3y 3 `permanently unite said members, I employ a t.
` j the tube a. adjacent to the tube b, which dam To rigidly and tubular. dam c, `which I insert into the end of is of suiiicient smaller diameter than the inand closed at its inner end by an outward The outer end of said wall c2, which closes the interior of the dam.
Into the cavity d I insert a core e, formed by casting therein a molten metal, which I spe- `ciallyl prepare for that purpose and whichgreadily amalgamates with the cold steel of t which the tubes a. and b are formed. Thel i `5e metal of the core eectually fills the cavity d, and in order to further anchor the core in the tube a I provide the latter with an orifice f through its side or with some other suitable key-seat extending laterally fromthe interior of the tube. The cavity d extends beyond said orifice and allows the molten metal of the core to run into and completely fill the orifice or key-seat. The outer end of the core is formed with a suitable brace, by which the member b is firmly tied to the member a.
When said members are to be united by the so-called flush joint, as shown in Fig. l of the drawings, I provide the side of the tube b adjacent to the tube c with an opening t' and insert into the member b a tubular dam or bushing g, which is flanged at its ends, as shown at g', to closely it to the interior of the tube b. The main portion of the dam gis of a smaller diameter than the interior of the tube to form a cavity hbetween them. This cavity is directly opposite and communicates with the cavity CZ, formed between the dam c and tube a, as hereinbefore described, and thus the molten metal of the core is allowed to flow into and fill both cavities h and d. For introducing said molten metal into said cavities I provide the side of the tube b with 'an aperture j and place the two members ct and b in a suitable mold @provided with the necessary gate O', communicating with the aperture j. The mold embraces a sufficientwportion of the member a to cover the orifice f and prevent the molten metal from escaping from said orifice. The molten metal is poured into the gate O', from whence it flows through the aperture j into the cavity h and thence into the cavity d, and by completely filling the two cavities it forms the core e, which rigidly and permanently unites the two members o. andi?.
The mold is obviously to be removed from the tubes a and h after the aforesaid casting of the core e is completed. y
In uniting the members d and b by a lap-v joint, as represented in Fig. 2 of the drawings, I use only the darn c in the tube a and dispense with the dam g and aperturesj and i in the tube b and employ a mold D, formed with the cavity D' around the exterior of the member b. rlhe end of the member ct is sufficiently remote from the side of the member ,b to allow the molten metal to iiow from the roo.
cavity D to the cavity d, in which latter the said metal is allowed to enter the orificesf and f', and thus forni on the core integral lugs filling said orifices and forming a secure lock between the core and tube. Themetal which fills the cavity C forms a band e around the tube b.
In practicing my invention in fastening the usual tubular members B B B2 to the crankhanger tube of a bicycle-frame I employ a tube l, which is formed with circumferential outward flanges Z on its ends. I place this tube, with the tubes B B B2 in their requisite relative positions, into a suitable mold O, as indicated by dotted lines in Fig. 4 of the drawings, which mold is formed with a cavity n around the tube Z and,if desired, also with a cavity'o around the end of the tube B. The tubes B' and B2 are provided with orifices p in their sides, and into the ends of said tubes I insert dams r, similar to the dam c hereinbefore described, which dams extend ,beyond the orifices p, as shown in Fig. 4t of the drawings. The orifices p,f, and f are each located remote from the end of the tube to form a positive and secure lock with the metal entering the same. The ends of the tubes B" and B2 are sufficiently remote from the tube Z to allow the molten metal to flow from the cavity n into the cavities surrounding the dams r. The mold O is provided with a suitable gate through Whichto introduce the molten metal, which in fiowing into and completely iilling the aforesaid cavities forms the tie t, which permanently unites the tubes B B' B2 with the tube Z. The uniting metal being deposited on the exterior of the tube Z forms the hanger-tube proper.
I claim- 1. In a tubular metallic frame the combination ofa tube disposed to extend laterally from the side of another tube and provided with a key-seat extending laterally from the interior of the tube and remote from the end thereof, and a core inserted in said tube and formed in one piece with a key anchored in the keyseat and with a brace tying the two tubes rigidly together.
2. In a tubular metallic frame, the combination of a tube disposed to extend laterally verse wall closing the interior of the dam, and
the inner end of said dam formed flaring to close the inner end of the aforesaid cavity, and a metallic core inserted into the said cavity and formed in one piece with a lug lling the orifice in the side of the tube and with a brace tying the tubes rigidly together.
3. In a tubular metallic frame, the combination of a tube disposed to extend laterally from the side of another tubeV and provided in its side with an oriiice located remote from the end of the tube to form a positive lock, and a core in Said lateral tube formed in one piece with a lug iilling said orifice and with a sleeve on its outer end embracing the companion tubes as set forth.
4. In a tubular metallic frame, the combination of a tube disposed to extend laterally from the side of another tube, a tubular dam inserted in said lateral tube and of smaller diameter to form around said dam a cavity extending lengthwise thereof, the inner end of said dam formed Haring to close the cavity thereat and the outerend of the dam formed with a transverse wall closing the interior of 'the dam, and a core inserted into the aforesaid cavity and formed at its outer end with a transverse extension tying the tubes rigidly together. y
5. In a tubular metallic frame, the combination of a tube disposed to extend radially from the side of another tube and provided with an orifice in its side, and two cores formed in one piece and inserted into the respective tubes and one of said cores formed with an integral lug filling the aforesaid orifice as set forth.
