This invention relates to a 'clock tomobile instrument board.

In "placing a clock upon an instrument board a difficulty has arisen in that the location of the clock movement in close proximity to the board positions the winding stem so closely to the board as to be diflicult of manipulation.

It is an object of this invention to conveniently locate the winding stem away from the instrument board.

A further object is to arrange for the use of a thin clock movement and a spaced dial the arrangement beiner intended for the lofor an aucation of the dial adJacent the instrument board whilel the clock movement with its winding stem is considerably removed from the board. A further object is to et `a clock assembly of variable depth, an one which makes use of but very few special parts lto secure the variability;l and another advantage to be attained is the possibility of puttin any shape or size of bezel projecting throug the instrument board on the same clock assembly whereby the final appearance of the clock is determined.

With these and other objects in view, the invention has been embodied in certain structures as herein shown and described in the accom anying drawings.

In the rawing: y Figure 1 is a front elevation looking to- .i ward' the instrument board from within the car. Figure 2 is a vertical section on line 2-2 v`Figure 1. Figure 3 is a horizontal section on line 3-3 in Figure 1. Figure 4 isa section through the spindle.

Referring to the drawing, referencenumeral 1 is usedto represent the instrument board of a car. Numeral2 shows a base member, Vin a recess 3 of which is placed a comparatively thin clock movement 4. 'I2-his clock movement is held 'in position -by screws 5. Projecting from the base is an apertured lu 6 carrymg an extended sleeve 7. Through t issleeve projects a winding stem 8 having at its`outer and a handle 9. Different from the usual. clock construction the dial 10 is spaced from the clock movement by means of a plurality of sleeves 11. Passing through the dial and sleeves 11 and threaded into base 2 are fastening screws 12. For the purpose of driving the hands of the clock, 13 two tubular driving spindles 14 and 15 are made use of. YThese spindles en- To complete the clock case a cylindrical casing membery 18 is secured to the base 2. This casing member extends to a point somewhat beyond the dial where it is provided wlth an annular outwardly projecting flange 19. A plate 20, circular in shape, is depressed between its outer portion and its central portion, and thc central portion is cut out as at 21 to 4form with the dial a clock face of appropriate .size and shape. It will be seen that the opening is out of the plane of the major part .of the plate and the. connecting portion is formed as.` a ledge 22 to engage the glass '23. Cooperating with the plate 20 is a plate 24. This plate 24 has its central portion cut out andis formed with a bead 25. This' bead engages the glass/.Q

around the opening, theopening correspondmg in shape and size with theopening in plate 20. Plate 24 is ofl greater extent than the plate 2O and its outer wall is bent over to form an annular ocket. Within this an-' nular pocket are t e flange of the member 18 and the outer portion of the plate 20. An annular spacing member 26 may also bemade use of between the flange of casing member 18 and plate20. This member 26 is refrably a gasket to seal the assembly om ust. v f

For securing the clock case to the instrument board, clamps are made use of comrising` threaded bolts 27 and U-shaped mem# -ers 28. l One of the larms of the U-'shaped member engages the instrument board and the other enga'ges the turned over edge of plate 24 as will be readily understood from examination of lthe drawlng.

By the mechanism described above it is possible to use a thin clock movement in a relatively deep case. The clock movement being` at the bottom of the case and its winding stem projecting therefrom considerably removed from the instrument board. In

so positioning the clock movement the dis-v curing the clock case on the board is such as to obtain the desired position of the dial and cooperating therewith is the novel means for holding the clock glass into position.

By the use of the parts, as described, assemblies of varying depths are provided for use upon different instrument boards.

But few special parts are needed to accom- I plish this-purpose, i. e., the casing 18, spac- 18 ing members 11, screw 12 and sleeves 14 and 15. These parts are all simple and cheap to manufacture.

The essential parts of the clock, such as the clock movement 11', dial 10 and hands 13,

would be the same in each case. In this Way it would be possible to have one model of clock manufactured in several depths, thev any shape or size of bezel projecting throng the instrument board on the same clock as- 30 sembly. This is made possible by using a plate 24, having a bead 25, the shape of which controls the final appearancelof the clock from the outside. It is obvious that very many different sizes and shapes of bead 25 can be had and still the circular plate 24 will fit the same flange 19 on the casing It will be, also, readily seen that these features make this type of construction an important improvement from the manufacturing standpoint.

Modifications of the specic structure shown and described above are possible and are Within the contemplation of the inventor.

I claim:

In` combination, a clock movement having a frame, a removable coaxial casing in extension of the frame, a dial in the end of thel casing remote from the frame, means for fixing the dial to the frame and casing, a'

removable extension shaft connecting the movement with the dial hands, and means for securing the casing to an instrument board. p l

In testimony whereof I aflix my signature.

JOSEPH ZUBATY.
