2 Claims.
This invention relates to a marking device for marking various articles.
It has been primarily designed for marking selected portions of quartz plates that are suitable for use as piezo crystals although it is susceptible of being used for a large variety of other purposes. In obtaining piezo crystals, sections of quartz plates are first carefully inspected under polarized light to determine which portions of the plate are suitable for use as piezo crystals. The locality of these portions on the plate is suitably marked for identification purposes and it is thereafter desired to properly apply a boundary marking around the locality. When this locality is thus bounded the remainder of the quartz plate that is unsuitable is removed therefrom.
The present invention contemplates a simple, convenient, and easily operable construction for applying the boundary marking, although as above stated the invention may be employed wherever it is desired to apply a suitable marking to an article.
More specifically, an object of the invention is to provide a supporting means on which the article that is to be marked may be positioned, a marking means, and a mechanism for moving the marking means into engagement with an ink Figure l is a top plan view of the marking device embodying the present invention, this being the embodiment of the invention in its preferred form;
Fig. 2 is a view in front elevation of the same; and
Figs, 3, 4, and 5 are partial vertical sections,
.taken substantially upon the line 3-3 upon Fig.
2 illustrating various positions assumed by the marking means.
Referring to the accompanying drawings wherein similar reference characters designate similar parts throughout, the marking device comprises a suitable box or container l0 within In the top of the box there is ing I l that is covered by a translucent window I i5. .tion of ground or sandblasted glass in the center 7 Which is disposed a light source, such as a fluo- *rescent tube I I that may be supplied with electric current from any suitable source of supply, such as through a cord l2. I3 indicates aswitch that is manually operable for turning oil and on the light source II.
formed an open- For this purpose I prefer to employ a secof which there is a depression [3 conforming in shape and size to the boundary marking that it is desired to be applied to the article to be marked, such as a section of quartz plate, indicated at P. The window it is attached to the top of the box Hi by corner brackets i1. On the back of the box there is an upright supporting arm 18 which in turn carries a support it for an ink pad 20 which is disposed above and rearwardly of the top of the box. 7

A pair of links 22 and 23 are provided. These links are pivotally connected to the marking means for rotation relatively thereto about nonaligned axes. Thus the upper end of the link 23 is pivotally connected to the top of the holder 24 for therubber stamp 2i while the upper end of the link 221s pivotally connected to the bottom of the holder 24 as viewed in Fig. 3. The 1 lower ends of the links are pivotally connected to the support It? for rotation relatively thereto about non-aligned axes. Thus, as viewed in Fig. 4, link 23 is pivotally connected to the upper rear corner or" the support 18 for rotation relatively thereto about a horizontal axis at this location. Link 22 has its lower end pivotally connected to the support it for rotation about a horizontal axis disposed downwardly and forwardly of the axis of rotation of the link 23. Link 22 carries a crank 25 which in turn may be connected to an operating wire it slidable through a cable housing 21. This operating wire may be operated by a foot treadle 29 hinged as at 36 upon a base 3|. A spring 32 may urge the treadle into uppermost position. One or more springs 33 may connect either or both of the links 22 and 23 to the support It. These springs serve to urge the marking means into a normal initial position as illustrated in Fig. 3 wherein the stamp 2i is in engagement with the ink pad 20. In this position it will be noted that the space vertically above the window I5 is unobstructed which will facilitate the positioning of the plate P properly with respect to the depression It. When the plate P has been properly positioned pressing on the treadle 23 causes a pull to be transmitted by wire 26 to the crank 25. This causes the links 22 and 23 to swing downwardly and forwardly about their respective non-aligned axes of rotation relative to the support it. During the start of this movement the marking means swings from the horizontal rearwardly directed position shown in Fig. 3 through the position shown in Fig. 4, and into the position shown in Fig. 5 wherein it engages the top surface of the plate P directly over the depression E6. The ink that is picked up by the stamp is thus transferred from the ink pad 29 to the plate P. When the treadle 29 is released the springs 32 and 33 cause the marking means to be returned from the downwardly directed vertical position shown in Fig. 5 through the intermediate position shown in Fig. 4 and back into the initial position shown in Fig. 3 leaving the space above the window entirely unobstructed.
In marking the plate P the plate is first carefully inspected under polarized light and the suitable locality or localities thereof are temporarily marked or identified. As the quartz plate is capable of transmitting light on being positioned under the window it and having light from the light source ii transmitted therethrough the selected locality can be readily positioned with reference to the depression l6. Consequently, when the stamp Ed is swung downwardly it applies to the plate a bounary marking vertically coincident with the edges of the depression it which are discernible through the plate P. While any suitable source of light might be employed within the box ill, I prefer to use a fluorescent tube so as to have a distributed light for eliminating the Window and the plate. Any other mechanism might be employed for operating the crank such as for example an electrically operated solenoid might be employed for causing the crank 25 to swing downwardly and forwardly against the action of the spring 33.
From the above-described construction it will be appreciated that the improved marking device is of relatively simple construction and has few moving parts. When the marking means is in its initial position it is completely removed from the vertical space above the window and above the article that is to be marked, leaving this space unobstructed, thus facilitating the application and removal of the articles to be marked and viewing the articles with reference to the depression i6.
Various changes may be made in the details of construction without departing from the spirit or scope of the invention as defined by the appended claims.
I claim:
1. A marking device comprising a horizontal support on which articles to be marked may be positioned, an ink pad arranged in an upright position above and to the rear of the support, a standard arranged between the support and the ink pad, a stamp, crossed links of substantially equal length pivoted to opposite sides of the stamp and to the standard at spaced points on a line between the support and the ink pad, and means for turning one of the links so as to cause the stamp to swing from engagement with the ink pad into engagement with an article on the support.
2. A marking device comprising a horizontal support on which articles to be marked may be positioned, an ink pad arranged in an upright position above and to the rear of the support, a standard arranged between the support and the ink pad, a stamp, crossed links of sub-stantially equal length pivoted to opposite sides of the stamp and to the standard at spaced points on a line between the support and the ink pad, means for turning one of the links so as to cause the stamp to swing from engagement with the ink pad into engagement with an article on the support, and spring means urging the other of the links into a position swinging the stamp into engagement with the ink pad.
