HAROLD W. SABOLD, OF PORT CARBON, PENNSYLVANIA.

INDICATOR.

Specification of Letters Patent.

Patented Mar. 30, 1920.

Application filed November 12, 1918. Serial No. 262,238.

To all whom it may concern:

Be it known that I, HAROLD W. SABoLD, a citizen of the United States of America, residing at Port Carbon, in the county of Schuylkill and State of Pennsylvania, have invented new and useful Improvements in Indicators, of which the following is a specification.

The purpose of the invention is to provide an indicator for attachment, prefer-' ably on front doors, by means of which the occupant of a house may indicate his or her wants to a tradesman or other person without the necessity of having to open the door to watch for such tradesman.

A further purpose of the invention resides in the provision of a neat and efficient form of indicator for this purpose.

As shown and described, a specific embodiment of the invention is adhered to but to this embodiment it is not to be restricted. The right is reserved to make such changes or alterations as the actual reduction to practice may suggest, in so far as such changes or alterations are compatible with the spirit of the annexed claim.

In the accompanying drawings:

Figure 1 is a view in front elevation show ing a portion of a door with the improved indicator attached.

Fig. 2 is a view in side elevation of the structure of Fig. 1.

Fig. 3 is a section on the line 3-3 of Fig. 1.

Fig. A is a section on the line H of Fig. 1.

As shown in the drawings, the invention comprises a circular casing 1 which is attached to the front of the door 2 by means of appropriate screws 3 which pass through its back a and enter the door. This casing is formed so as to be open at one side in or der that the indicator elements may be ex posed to view or hidden within the casing.

The casing is closed on the front by a removable cover 5 held frictionally in place one edge to the casing.

In order that a housewife or occupant of a house on which the device is used may indicate that she is not at home, there is provided a slide 6 on which is imprinted the word Out. This slide enters the guide 7 carried by the cover 5 on the rear thereof and reaches the outside of the cover through an appropriate slit formed therein. It is obvious that moving the slide in one direcmay tion will cause its indication to be hidden behind the cover 5; the reverse of this movement will of course expose its indication to view.

Mounted in the casing 1 there are the indicating blades 8, 9 and 10, the latter being carried on a shaft 11 pivotally mounted in the cover 5 and extending through the back 4 and the door 2, carrying at its inner end a knurled head- 12. The indicator 9 is mounted at the end of a hollow shaft 13 which loosely surrounds the shaft 11. This shaft 13 also projects through the door 2 but terminates short of the end of the shaft 11, so that its head 14 which is also knurled stand between the door and the head 12. The indicator 8 is mounted on the shaft 15 which being hollow loosely surrounds the shaft 13, this shaft also extending through the door 2 but terminating short of the head 14:, so that its head 16 may stand adjacent the inner face of the door.

A finishing plate or escutcheon 17 is mounted on the door beneath the head 16, to give a proper finish to the device from the inside.

The shaft 11 carries a collar 18 and the shaft 13 a collar 19, the former collar abutting the indicator 9 and the latter the indicator 8, both the indicators 8 and 10 carrying integral collars abutting the back 4: and cover 5 respectively. By this construction the several indicators are held in spaced relation to each other and the shafts which carry them are precluded from longitudinal movement.

It is obvious that any one or all of the indicators may be raised to indicating position where they stand exterior to the casing or lowered to non-indicating position where they stand within the casing, the handles or heads 12, 1A and 16 provide the means for turning the individual shaft of this indicator to effect the performance of these functions.

From the foregoing description and the accompanying drawings, it is believed that a clear enough understanding of the invention will be had to render further description unnecessary.

The invention having been described, what is claimed as new and useful is:

. An indicator for the purpose set forth comprising a circular casing for attachment to a door or partition, the said casing being provided with a removable cover on its front face and being open on one side, a shaft having one end pivotally mounted in the cover of the casing and extending through the back thereof, the center of said shaft being eccentrically exposed with reference to the center of the casing, tubular shafts in surrounding relation to the first said shaft, segmental indicators connected to all of said shafts, spacing collars carried 10 by the shafts and interposed between the HAROLD W.
