Description

- r. SERPICO PROTECTIVE GUARD Filed Sept. 24, 1923 i ATTORNEY throws off small sharp metallic particles Patented -Mar. 3, 1925. I
UNITED STATES THOMAS SERIPICO, OF BROOKLYN, NEW YORK.
PROTECTIVE GUARD.
Application fi1ed September 24, 1923. Serial No. 664,642.
To aZZ whom it may concern Be it known that I, THOMAS Sunrise, a citizen of the United States, residing at Brooklyn, county of Kings, borough of Brooklyn, and State of New York, have invented new and useful Improvements in Protective Guards, of which the following is a full, clear, and exact specification.
My invention relates to guard devices and refers particularly to guard devices suitable for use with those machines which produce flying metallic particles.
lVithout limiting myself to the described use, I prefer to show it in connection with a routing machine, to which it isparticu- .larly adapted. Y
In the routing of electroplates, and similar metallic plates, it is necessary that the face of the operator be sufficiently near to the revolving router cutter to enable him to clearly observe the work which is frequently of a. delicate character.
The rapid revolution of the router cutter with considerable force, thus endangering the face, and particularly the eyes of the one operating the machine.
The object of my invention is a glass guard so constructed that it may be fixed into a desired guarding position and which can be readily removed for cleaning purposes and as easily replaced without change of operating position.
In the accompanying drawings, illustrating one form of my device, similar parts are designated by similar numerals.
Figure 1 is a perspective view of one form of my frame and connecting member.
Figure 2 is a perspective view of one form of my device in operating position with a routing machine.
Figure 3 is a perspective View of one form of my router-rod support.
Figure l is a section through the line H of Figure 2.
Figure 5 is a section through the line 55 of Figure 2.
The particular form of the device of my invention shown in the accompanying drawings comprises a frame having the channel sides 10, 11, 12 and 13. The frame is closed upon the sides 10, 12 and 13, but is open upon the side 11 to allow of the insertion of a plate of glass let, which rests upon the inner faces of the channel sides 10, 12 and 13 and is maintained in position by the cotter-pin 15. The corner between the sides and 13 is cut away as indicated to fit around the member 16 of the routing machine. The side 13 .is extended upwardly at right-angles into the frame-support 17 having a plurality of holes 18, 18, 18 there- 1n. Theframe-support 17 may be affixed to, and not integral, with the side 13 if desired.
A router-rod support comprises the member 19, having an opening 20 through which the router-rod 21 may pass the screw-bolt 22 acting asa locking means. The extended arm 23 of the router rod support has a recess, or split opening 24, for purposes described later.
A connecting member comprises the flat arm 25 having an opening therein and the three sided member 26 capable of placement over the member 23 of the rod support having a pin 27, capable of placemenewithin the recess 2% of the rod support member 23.
The method ofarranging and employing my device is as follows A The cotter-pin is withdrawn and a glass plate 14 is inserted within the frame, and the cotter-pin replaced to hold the glass from accidental displacement. The routerrod support is then placed by passing the router-rod 21 hrough the hole and is fixed or set, by means of the threaded binding bolt 22.
The connecting member is then fastened to the desired hole 18 of the frame support 17 by means of the bolt and nut 28.
The member 26 of the connecting member is then placed over the member 23 of the router-rod support and the pin 27 allowed to fall into the recess 24.
It is evident that the distance of the glass guard from the routing machine can be determined by the position of the router-rod support upon the router-rod, that the height of the guard from the table and its inclination be controlled by the bolt and hole connection between frame and the connecting member.
By setting the bolt 22 and the bolt 28 at the proper positions, the frames and glass guard can be easily removed for cleaning or other purposes and replaced without interfering with the proper adjustments of the several parts, as this can be accomplished by simply raising and removing the connected frame and connecting member from the router-rod support.
It is to be noted further that by means of the plurality of holes 18, 18, 18, the guard can be so positioned With respect to the router cutter 30, both as regards height and inclination, as to afford complete protection to the face of the operator, without in any way interfering with his sight of the cutter and the plate upon Which he is working.
The device of my invention presents a simple, accurate and efficient guarding means for the protection of operators of metallic particle producing machines.
I do not limit myself to the particular size, shape, number or arrangement of parts as shown and described, as these are given simply as a means for clearly explaining my invention.
lVhat I claim is 1. In a guard, in combination a rod support having a hole therein capable of receiving a rod, means for fixedly attaching the rod support to the rod, an extended portion of the rod support having an opening therein, a connecting member having an etitended member capable of being positioned in the opening of the extended portion of the rod support, a frame, means for attaching the frame to the connecting member in a plurality of removable positions and a removable transparent plate carried by the frame.
2. In a guard, in combination, a rod support having a hole therein capable of receiving a rod, an extended portion of the rod support having a recess therein, a connecting member having a portion capable of placement around the extended portion of the rod support and having a pin capable of placement within the rod support recess, a frame, a frame support having a plurality of holes, means for attaching the connecting member to the frame support by means of any desired hole therein and a removable transparent plate carried by the frame.
3. In a guard, in combination, a rod supporting member having a hole therein capable of receiving a rod, an extended portion of the rod support having a recess therein, a connecting member having a portion capable of placement around the extended portion of the rod support and having a pin capable of placement Within the rod support recess, a frame, aframe support at right angles to the plane of the frame having a plurality of holes therein, a bolt capable of attaching the connecting member to any desired hole of the frame support allowing of a desired inclination of the frame and a transparent plate removably carried by the frame.
Signed at New York City in the county of New York and State of New York this 21st day of September, 1923.
