BLANK-FEEDING DEVICE FOR WIREYVORKING MACHINES.
Application filed March 13, Serial 1%. 15,375, and in Germany March 31, 1924.
This invention relates to blank feeding devices for wire working machines of the kind including one or more rotating teed screws, and it has for its object to providea device of t iis kind in which the feed screws have a plurality of threads on the station where the blanks ted by them are operated upon, these threads being connected with each other by a recess which extends transversely to the axis of the screw and within which the blanks are held against movement with relation to the operating tools during a partial revolution of the screws.
The present feeding niecliamszn oi simple construction and is of such a nature that only the blanks which have reached the working station are brought to a standstill with respect to the tools, while all other blanks of the row of blanks ted by the screws continue their forward movement.
The invention will now be described with reference to the'accompanying drawing in which:
The figure is a plan View of the feeding device.
The device includes two parallelly' arranged feed screws (6 and b of the same construction. These screws rot with the same angular speed and in the sa ne sense in such a direction, as indicated by arrows on the drawing, that the wire blanks cl placed them are moved from the left to the right. A bar 0 serves to guide the blanks (Z which bear by one end against that bar. The portion 0 of the screws lying near the station where the blanks are operated upon, is double threaded while the other portions of the screws are single threaded. The bottoms of the two threads 01 each screw are in communic tion with each other by a recess 7 extending transversely to the axis of the screw. As soon a blank coming from the left has entered the recess f it remains at a standstill therein during a partial revolution of the screws. During this time the blank is worked upon by the tools. According to the embodiment shown in the figure, the blanks 6Z1, (Z (Z (Z moving towards the working station and the blanks having already undergone its operation are conveyed from the left to the right, while the blank (Z under operation is at a standstill. The device described is more particularly designed for use in connection with mato the other end of the screw. The'other thread 1 is similarly arranged, its first turn y beginning not at the recess but at a certain distance ahead of the recess 7. It would of course be sutlicient to have the two threads extend only up to' the recess 7. The. blanks are held in the positions indicated by using two parallel teed Screws of the same kind. As the blanks (Z extend in the same direction as the recess f, the blanks conveyed by the thread 00 towards the recess 7 will not pass across the recess into the turn but they will enter the recess 7 and move from the same directly into the thread y. On the portion 6 of the screws those turns of the threads w and 3 which exert a feeding action on the blanks are marked by arrows. The thread turns 00 and 2y do not take part i the feeding operation. As will be seen in the drawing, the distance by which a blank (Z is moved on between the positions (Z d at every revolution of the screw, corresponds to a thread pitch- Butbetween the positions (Z cZ the distance by which the blank is fed on during one revolution of the screw corresponds to only hall. thread pitch, because in passing through the recess f the blank remains at rest for the time which the screw takes for executing halt a revolution. This means that, in the embodiment illustrated, the threads as and y are staggered with relation to each other by 180 degrees.
It would notin any way influence the operation of the device it the feed screws were multiple threaded throughout and it one or certain of the threads were utilized for the feeding operation. There may also be arranged along the feed screws'a plurality of working stations. At the working stations the threads may be recessed so that during the working the blank remains at rest for any desired part of a revolution of the feed screws.
The tools and any other parts of the machine are not shown and described because they do not form any part of this invention versely to the screw axis and connecting the 10 several threads With each other; the said recess being adapted to temporarily receive the blanks fed by the screw and hold them against further movement for a time corresponding to a partial revolution of the screw.
In testimony whereof I have signed my name to this specification.
JACOB RODERBURG.
