FEEDING DEVXCE FOR THE WORKPIECE 0N PLANING MACHINES Filed April 25, 1955 1:762 ELECTRQMAGNET ii 3 6 I ELECTROMAGIVET F WH- Ambelang ATTYS United States Patent FEEDING DEVICE FOR THE WORKPIECE 0N PLANING MACHINES Friedrich Wilhelm Hermann Ambelang, Flensburg, Germany Application April 25, 1955, Serial No. 503,618
Claims. (Cl. 144-114) It is known in connection with planing machines to fit in front of the cutter spindle a device by which the workpiece is held between rollers provided with chamfers. This device can certainly prevent thin workpieces from pulsating over the cutter spindle at the commencement of the feed, it is, however, not suitable for preventing timber resting concave on the horizontal planing table from altering its position relatively thereto during the feed, and it cannot influence the direction of the workpiece running through.
The invention relates to a feeding device for workpieces on planing machines. This feeding device has at least one straight guiding surface for resting on a table plate of the planing machine and in the case of a planing machine working on two sides, a straight guide surface on each side for resting one against an upright side and the other against a flat side of the table plate and which is provided with teeth, known per se, for engaging in the rear end of the workpiece. Thus reliable guiding of the workpiece during the feed is obtained in a simple manner with the aid of the device, preventing twisting and rocking movements and, as soon as it comes near the cutter spindle, the feeding device can be easily detached from the workpiece by withdrawal.
Another feature of the invention in the construction of the feeding device for planing machines working two sides in combination with magnetic adhesion, known per se, consists in that the feeding device acts by magnetic adhesion simultaneously on two of its guiding surfaces, namely on the guiding surface facing the flat side and that facing the upright side of the table plate.
Finally the feeding device has a handle which is constructed as a buffer cooperating with an abutment provided for limiting the feed of the device.
A preferred embodiment of the invention is illustrated by way of example in the accompanying drawing, in which Fig. 1 is a side elevation, and
Fig. 2 a top plan view of a feeding device on the table top of a planing machine;
Fig. 3 shows the feeding device alone in side elevation;
Fig. 4 is a top plan view, and
Fig. 5 an end view thereof.
The feeding device 1 consists substantially of a body slidably arranged on a table plate 8 of a feed table of a planing machine: On the side facing the flat side of the table plate 8 the feeding device 1 has a straight guiding surface 13 bearing against the table plate and on its side facing the upright side 9 of the table plate 8 another straight guiding surface 14 bearing against this upright side 9. At its front end the feeding device 1 is provided with sharp teeth 2, points, pins or the like, which as the feeding device is moved forward against a wooden workpiece to be fed for the purpose of working, force their 2,771,920 Patented Nov. 27, 1956 "ice way into the rear end face of the workpiece after which the position of the workpiece is dependent upon the guiding of the feeding device. During the feed movement, during which the feeding device is moved by the hand holding a handle 15 or can be moved by known mechanical arrangements, and is steadily presed with its guiding surfaces 13, 14 against the flat side and the upright side of the table plate respectively, the workpiece 10 is simultaneously worked on two sides by a horizontal cutter spindle 11 and a vertical cutter spindle 12. The feed of the workpiece 10 by the feeding device 1 is carried out to within a short distance in front of the horizontal cutter spindle 11 where a buffer 3 provided on the handle 15 of the feeding device and which may be made of rubber, comes into contact with a stop or abutment 5 provided for limiting the feed. By withdrawal the feeding device I can easily be detached from the workpiece 10 at this point, after which the workpiece covers the short remainder of its travel alone being guided by hand or by a mechanical drive. The reliable bearing of the guiding surfaces 13, 14 of the feeding device 1 is ensured by the provision of electromagnets 6 and 7, of which the magnet 6 facing the flat side and the magnet 7 facing the upright side 9 of the table plate 8 are simultaneously efiective. Known permanent magnets might also be provided instead of electromagnets.
From the above detailed description of the invention it is believed that the construction will at once be ap parent, and while there is herein shown and described a preferred embodiment of the invention, it is nevertheles: to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.
1 claim:
1. A feeding device for workpieces on planing machines comprising in combination with a table providet with a planar surface located in one plane and anothe1 planar surface located in a second plane substantial!) transverse to said first mentioned plane, a first guiding surface bearing against the first mentioned surface of salt table and a second guiding surface bearing against tht second mentioned surface of said table, teeth means pro vided on the front face of said device for engaging tht rear portion of the workpiece, stop means on said table and a handle on said device provided with buffer mean: for engaging said stop means so as to limit the feedin; stroke of said device.
2. The combination as set forth in claim 1 includim electromagnetic means on said device for maintainin continuous contact between said table surfaces and sait device during the feeding of a workpiece along said tablt surfaces.
