SPRING-FORMING MACHINE.
Original a'pplication filed October 9, 1924, Serial No. 742,598. Divided and this application filed December 16, 1925. Serial No. 75,745.
My present invention relates to spring forming machines of the general class or type set forth in Letters Patent of the United States No. 1,275.377, granted to Samuel S. Riegel and myself, August 13, 1918, and Nos. 1,428,626 and 1.459.045, granted to me September 12, 1922. and June 19, 1923 respectively and is a division of my copending Patent No. 1,572,639, granted February 9, 1926, for spring-forming machine. The object of my invention is to turther improve the means for holding the formation plate and regulating the *ariation of temperature of the spring plates.
The improvement claimed is hereinatte fully set forth.
In the accompanying drawing: Figure 1 is a partial plan or top view of a spring forming machine, illustrating an embodiment of my invention; Fig. 2, a view, partly in elevation and partly in section. of one of the presscr blecksthereot; and. Fig. 8, a similar View. taken at a right angle to Fig. 2.
In the practice of my invention, referring descriptively to the specific embodiment thereof which is herein exemplified, the leading" and characteristic features of the means for bending or shaping the plates are substantially similar to those of the several Let ters Patent hereinbefore specified. Said bending means are located on the top of a table, 1, which is supported on, and overlies a portion or" an oil tank. They comprise, as heretofore. a rigid abutmentmember, 1*. sup porting abutment members, 9, a flexible resistance member, 7, and a cross-head, 3, ac t-uated bv piston, working in a cylinder. 2, fixed on the tahle. the outer end of the rod, 2". of said piston. being secured to the crosshead. The specified forming mechanism noted is notthe efore claimed as of my pres ent invention, and any other suitable and preferred term may i he applied without departure therefrom.
In accordance with my present invention, an improvement is made in the presser blocks, 4. through which pressure is transmitted from the crosshead, 3. to the spring plates 5, in bendin them to the proper forms against the formation plate 6. As most clearly shown in Figs. 2 and 3, cylindrical seats, 4, are formed on the presser blocks, around which are wound coils of wire, 38, whereby they may be converted into electro-magnets. The circuit, 39, of said coils, is connected to an automatic switch, 40, located in position to be opened and closed by the cross-head, 3, in its reciprocating movements, the circuit being closed when the cross-head moves back after forming a spring plate, whereby the magnetizcd presser blocks draw back with them, the relatively cold formation plate, leaving the spring plate, if atthe requisite temperature, on the relatively cool movable table section.
Should the spring plate be at a temperature below that required for its proper hardening in the oil bath, itwill also be subject to the magnetic attraction of the presser blocks, andbe withd mm with them and the foundation plate instead of being dropped into the oil tank. A valuable check is provided upon the degree of heating of the spring plates. I1" desired, the magnetic circuit may be maintained during the operation of the machine,
subject to manual control, and the automatic switch may be omitted.
I claim as my invention and desire to se cure by Letters Patent:
' 1. In a spring forming machine, the combination of a flexible resistance member; a formation plate; presser blocks, cooperating with said plate; and means for converting said presser blocks int-o electro-magnets to prevent release of formedsprings at other than tempering temperature.
2. In a spring forming machine, the combination of a flexible resistance member; a. formation plate; presser blocks, cooperating with said plate; and intermittently operative means for converting said presser blocks into olectro-magnets to prevent release otformed springs at other than tempering temperature.
3. In a spring forming machine, the combination 01: a flexible resistance member; a formation plate; prcsser blocks, cooperating with said plate; and magnetic coils on said blocks, for converting them into electro-magnets to prevent release of formed springs at.
other than tempering temperature,
THOMAS F. BUCKLEY.
