WIRE-FEEDING MECHANISM FOR HAIR-PIN MACHINES.
Specification of Letters Patent.
Patented July 15, 1919.
Original application filed February 5, 1918, Serial No. 215,500. Divided and this application filed May 27,
1918. Serial No. 236,812.
To all whom it may concern:
Be it known that I, HOMER P. SMITH, a citizen of the United States, and resident of Appleton, in the county of Outagamie and State of lVisconsin, have invented certain new and useful Improvements in lVirc-Feeding Mechanism for Hair-Pin Machines; and I do hereby declare that the following is a full, clear, and exact description thereof.
My invention relates to new and useful improvements in means for feeding an endless piece of wire to any preferred operating mechanism, but is particularly directed to means for feeding wire in hair pin forming machines, such as is illustrated in my copending application Serial No. 215500, filed February 5, 1918. In fact the present application has been divided from said pending application.
This invention has for its object to provide mechanism which will be positive in action, efiicient and automatic in operation, and economical in use.
An additional object is to provide means whereby the wire may be moved different distances depending upon the length of the legs of the hair pin or other article to be formed therefrom.
A still further object is to provide simply constructed mechanism for carrying out the foregoing aims and one which can be. readily mounted upon various types of machines.
Various other obvious objects and advan tages which naturally arise from the improved structure are also contemplated, such structure being illustrated in its preferred form in the accompanying drawings in which:
Figure 1 represents a vertical transverse sectional view taken substantially on the plane of the line 1-1 of Fig. 3.
Fig. 2 is a plan view of the invention, and
Fig. 3 is a longitudinal vertical sectional View through the parts shown in Fig. 1.
Referring more particularly to these drawings wherein similar reference characters indicate like parts throughout the views, the numeral 1 denotes a portion of a work table of a hair pin forming machine in which the several operating and actuating mechanisms used in the formation of a hair pin are mounted, the present invention being limited to the wire feeding mechanism thereof.
In applying my invention to the work table 1 over which the endless wire lV longitudinally moves. the same is provided with an elongated longitudinally disposed opening 2, the opposite side walls of the same each having a track in the form of a channeled bar 3 secured thereto. Between these bars and slidable longitudinally thereof is a carriage 4, the same being in the nature of a block having laterally and oppositely ex tending ribs 5 for sliding engagement in the channels 6 of said guides.
The carriage 4 is provided with upwardly and longitudinally extending flanges 7 to form a channel through which the wire lV moves as indicated most clearly in Figs. 2 and 3, said carriage forming one element of a wire gripping mechanism, the cooperating element of which comprises a bell crank lever S pivoted between said flanges as at 9 and having one arm 10 positioned in said channel. The lower face at the free end of this arm 10 is serrated or roughened for engagement with the wire W, the latter being gripped between said face and a similar roughened face of a hardened contact mem her 11 disposed in the bottom of the channel of the carriage.
The other arm 12 of the bell crank lever S has an enlarged opening 13 formed therethrough adjacent the pivot 9 to receive said wire \V, and the free end portion is elongated and in the form of a cylindrical stem 14. This stem is slidably and rotatably disposed in the vertical bore of a head 15 that is pivoted at 16 on the outer end of a sleeve 17 This sleeve in turn is slidable and rotatable on a cylindrical crank arm 18, the latter being preferably formed integrally with and extended laterally from a collar 19 which is fixed on the lower end of a vertical rock shaft 20.
From the drawings it will be noted that the arm 12 of the bell crank lever extends below the table 1 and that the other clements, including the head 15, the sleeve 17, the crank arm 18 and the collar 19 are similarly located. The rock shaft 20 extends through the table 1 and is journally mounted in an elongated bearing housing 21 carried thereby; the upper end of this rock shaft has a collar 22, similar to the collar 19, fixed thereto from which an upper crank arm 23 projects.
A pulley wheel 24 having a convex periphery is slidably and rotatably mounted on the upper crank arm 23 and is designed to have the concaved periphery of an eccen trio '25 engaged therewith. This eccentric 25 is splined. on a shaft 26 located above the table 1 and positioned parallel thereto. It is obvious that as the eccentric rotates the crank arm 23 will be moved toward and away from the shaft 26, and that further, by moving the eccentric longitudinally of the shaft to dispose the pulley wheel 2 1 different distances from the free end of the crank arm 23, the shaft 20 will be rocked different amounts corresponding with the position of said pulley Wheel.
Inasmuch as the carriage 1 is connected with the rock shaft 20, the movement of the latter will cause the former to be shifted longitudinally between its tracks 3, such movement being from right to left when the machine is viewed from the direction indicated by Fig. 3. Said carriage is shifted in the opposite direction or returned toits original positlion by a plurality of contrac-- tile springs 27, one end of each of which is secured to the table 1 or any other stationary obj eet and the other endto the freeend of an arm 28 fixed to the lower end. of the rock shaft 20. A plurality of the springs 27 is provided in case one or more should break during the operation of the machine.
The gripping of the Wire V by the bell crank 8 and the release thereof takes place automatically upon movement of the carriage 4; in different directions. That is to say when the carriage is moving toward the right-hand end of the machine as viewed in Fig. 3, the gripping end of the horizontal arm 10 of the bell crank Sand the contact member 11 will be inactive and the wire will slide between the same; on the other hand when said carriage is moved'toward the lefthand end of the machine the wire is gripped and pulled in the same direction. This result is accomplished merely by the provision of said bell crank, this memberbeing so pivoted that any force which [is applied to the end of the arm 12 will cause the same to rock and therefore actuate the other or gripping \arm 10. Therefore inasmuch as the direction of force as applied to the arm 12 by the crank 18 is from one direction when the carriage is movingtoward the right and from the reverse direction when it is traveling toward the left, the proper movements of the gripping arm 10 will take place automatically. As hereinbefore indicated, shifting of the eccentric 25 on its shaft 26 will cause the rock shaft 20 to be oscillated diiferent degrees, this arrangement being provided so that hair plins or other articles of different lengths may be made on the same machine.
It being desirable to have the carriage stop at a predetermined point, especially when moved toward the right, the same is provided with a spning-pressed detent 29 which is adapted 'to cooperate with one or more notches formed in a locking bar 80.
the position of the notches. In this manner the carriage will always stop at the necessary point even though there is considerable freedom of movement between the parts which connects said carriage with the rock shaft 20. Said spring pressed detents 29 also yieldably opposing movement of the carriage inwardly from its limits of reciprocating movement, and thereby insuring actuationof the gripping member formed by the lever 8, prior to movement of the car riage.
Various minor changes may be made in the form and proportion of the several parts of the invention without departing from or sacrificing any of the principles and advantages thereof.
