SU16407A1 - Safety device for woodworking milling machines - Google Patents

Description

In the proposed safety device, two rulers are used, mounted on the wall, one relative to the other in the required position, by means of fixing bolts sliding in the drawstring, hinged to the rulers, with arched earrings fitted with caps covering the router. To cover the latter in front, there is a shield, supported by a adjustable stop and moved in the guide bars with a lever under the action on the last item to be processed. In the off position, the flap closes the router with an action on the lever of the spiral spring.

In FIG. 1 is a view of the proposed Device in the rear; FIG. 2 is a top view thereof, and FIG. 3 is a sectional view of FIG. 2

To the machine A (Fig. 1), bolts L, / Ci and Kg, press the earrings P, Pi, C, Ci, pivotally connected to the rulers D, d and. A,, with which the rulers rf and rfi are fixed on the rulers D, DI with sheep, which allow axial displacement of the rulers one in relation to the other (Fig. 2). Caps / and FI are attached to the earrings Q, C, covering the router M

The ruler is equipped with a guide slot for a carrier s, carrying a spring covering plate

(Fig. 2), supported by the adjustable stop L, and the link, and its associated bearing point 6, line D, d-lever s, and loaded with spring x (Figs. 1 and 2).

When operating, releasing the bolts K is set at the desired angle of the ruler and and the arc C Ci with the caps / FI entering into one another. Then, the guide bars d, d and the adjustable stop L are set to the required position. From pressing object B (Fig. 2) on, p1chag s, the latter, acting on the carrier s, moves the flap g /, thereby opening the working cutter N which is closed by the action of the spring .g as soon as the object to be processed 5 ceases to come into contact with the lever s

The subject of the patent.
