-5Claims. 1

My invention relates to clocks, and more particularly to a type of clock that may be constructed of a few parts assembled without the use of tools.

The object of my invention is to provide a clock, constructed of simple parts, assembled into a compact kit with simple instructions and directions for the assembly of the parts into a clock without the use of tools or mechanical skill.

A further object of "my invention is to arrange the parts comprising the device in a manner that they may be, when assembled, actuated by means of a weight and adjusted in a manner to keep correct time.

A still further object of my invention is to provide a disassembled device that is educational in its arrangement, and assembling of the component parts thereof, the parts being simple in construction, economical in cost and easy to assemble by following simple directions.

Other and further objects of my invention will become more apparent as the description proceeds when taken in conjunction with the drawings, in which:

Figure 1 is a plan view of the face plate and the actuating parts mounted thereon.

Figure 2 is an end view of the device, shown in Figure 1, illustrating the assembly of the various parts.

Figure 3 is a front view of the auxiliary plate t! forming a part of the assembly and showing the parts mounted between the auxiliary plate and the face plate.

Figure 4 is a plan view of the parts mounted on the rear of the auxiliary plate which is shown in phantom.

Figure 5 is a front view of the entire device with the various parts mounted onto the front face and with the parts behind the front face and auxiliary plate shown in phantom.

' Figure 6 is a front view of a modified governor bar provided with adjustment weights, and

Figure '7 is an end view of the governor bar and weights as shown in Figure 6.

Similar characters of reference indicate corresponding parts throughout the several views, and referring now to the same, the character III shows a face plate which is supported outwardly from the auxiliary plate H by means of spacers l2 which engage the plates ill and ii, and the auxiliary plate H is supported by spacers t3 extending at right angle thereto when the assembled device is suspended from a vertical wall.

A drive shaft l4 provided with a drive wheel 15 'on the front of the face 10 extends rearwardly 2 through the auxiliary plate H and supports a driven wheel l6 behind the plate II. There is a belt I! in the form of a rubber band leading from the peripheral surface of the driven wheel it over a pinion 18, which is disposed in direct alignment with the wheel l6 and which is mounted on a shaft l9 extending through both the plates Hi and H and journaled therein. The shaft l9 supports an escapement wheel 20 at its forward end on the front face of the plate 10. This wheel 20 is a part of the governing mechanism for regulating the speed of the clock as a unit and has a plurality of outwardly extending pegs 2'] engaging its front face and extending outward at right angle therefrom. In direct vertical alignment with the shaft l9 and supported by a lower bearing 22 is a vertical shaft 23 guided .near its upper end b a bearing 24. The

bearings

22 and 24 extend outward from the face 10 for a sufficient distance to place the vertical shaft 23 ahead of the pegs 2| on the wheel 20 and a pair of

vanes

25 and 26, attached to the shaft 23 at a pre-determined angle, extend inwardly toward the face of the wheel 20. The extreme upper end of the vertical shaft 23 supports a governor bar 21 which acts as a pendulum or governor by reciprocating back and forth. It is fastened to the upper end of the vertical shaft 23 and its motion turns the shaft 23 enough to allow the pegs 2| to escape the vanes 25 and 2 6 one at a time, thereby arresting the revolving -o the wheel 20. I

In Figures 6 and '1, I illustrate a manner in which the governor bar 27 may be provided with a plurality of notches 28 on its upper face on each side of the shaft 23. The weights are shown in the form of annular washers 29 suspended from the notches 28. These Washers may be moved to Ward and away from the central mounting of the bar 21 on the shaft 23, thereby causing the reciprocating motion of the ,bar 21 to be slowed. up whenv the washers 2B are moved toward the ends of the bar :21 and sped up when the washers 25 are brought inwardly toward the center of the bar 21.

I show these washers as a means of control bu the peripheral edge thereof. This cord 33 extends in looped fashion over a drive wheel I and from it extends downward over the periphery of a pulley 34 and from it to an idler pulley which is journalled on a shaft 36 and extends outward from the face plate III.

The cord 33 is fastened at its other end to a pulley frame 31. The pulley assembly consisting of the pulley 34 and the frame 3'1 which supports it suspended on the cord 33 in the manner shown and are urged downward by means of a weight 38 which is disposed over the spacer on the frame 31 at 39 by means of a hook 40. This weight 38 ohviously may be a solid mass of metal or the like or may be constructed in the form of a cylindrical bucket, which may be filled with sand'or lead pellets, the weight of it acting as a means for driving the entire mechanism.

The shaft 30, which is journalled through both plates ID and II, supports a pinion 4I which in turn actuates a large wheel 42 mounted on a shaft 43, the actuation being accomplished by means of a. rubber band 44 acting as a belt. On this same shaft 43 is a pinion which is connected to a dial wheel 46 which is mounted to a shaft 41 by means of a rubber band 48. This dial wheel 48 mounted to the shaft 4? actuates and turns the indicator 49 on the face Iii of the clock, and acts as a hand or pointer to indicate the time on an annular dial which may be in the form of a sheet of paper adherently attached to the face plate ID or may be directly inscribed into or onto the face plate ID. The numerals on the dial 50 are spaced into .twelve hours and each hour period is divided into four periods.

In operation, the device is assembled and functions as follows:

The two plates l5) and I I are placed in parallel relation to one another and held in spaced relation by means of the spacers I2. The spacers I3 are next placed into the apertures provided in the auxiliary plate 9 I to keep the assembled device supported away from a vertical wall or the like from which it is suspended. The wheel 3I on the from contact with the periphery of the wheel I5. This will cause the entire weight 38 and pulley assembly 34 to be brought upward toward the face 'plate. When this weight is brought up to the top, the cord is looped over the wheel I5. weight is released, it will cause a downward pull- As the ing action which will cause the wheel I5 to revolve in'a clockwise direction taking the cord from the reel or reservoir 3 I, and due to the idler pulley 35 it will permit the entire weight assembly to move downward. As this cord 33 is pulled downward, it will cause the wheel I5 to move in a clockwise direction, thereby turning the shaft I4 and the large wheel I6 mounted to the shaft I 4 between the plates ill and I I. A belt I! in the form of a rubber band engages a wheel I8 mounted on a shaft I9 and this shaft I9 has the escapement wheel 20 mounted to its forward end and outside of the face plate Ill.

The lower bearing 22 and the upper bearing 24 guide a vertical shaft 23 which is in direct These vanes are in direct alignment with pegs shown as 2I. In the illustration, there are seven of these pegs extending outward from the face of the escapement wheel 20 and the angular relation of the

vanes

25 and 26 will permit a peg 2I to pass and the rotation of the wheel will be arrested by the other of the vanes. Thus, due to the belt H, the wheels IS will cause the shaft I9 and the escapement wheel 20 to rotate and the rotation will be controlled by this escapement movement. The top of the shaft 23 is supplied with a governor bar 27 which is of a weight and size to coordinate its movement with the weight 38 at the bottom of the cord 33.

In Figures 6 and '7, I show a pair of washers suspended in notches on the bar 21. These washers, acting as weights, control the reciprocated action of the bar 21 allowing it to move faster when they are near the shaft 23 and slowing up the action when they are far apart on the bar 21 and away from the shaft 23. The speed that the escape wheel 29 will travel will determine the revolution of a large wheel 3! mounted on a shaft 30. This wheel 3|, as stated before, is the reel for the cord 33 and as the shaft 30 revolves, it will revolve a pinion 4| which in turn will revolve a large wheel 42 mounted on a shaft 43 due to its contact with the rubber band acting as a belt 44. The wheel 42 will turn the shaft 43, and a pinion 45, mounted on this shaft 43, will rotate the dial wheel 46 which is mounted on a shaft 4?, which shaft is journalled in both plates I 0 and II.

On the face of the face plate If] is a printed dial, shown as 50, spaced off, as described, into quarter hour periods and the shaft 4'! has at its forward end an indicator hand, shown as 49, which indicates the time by quarter hour periods. It will be manifest to anyone that is familiar With the art that the component parts constituting the device can be made of wood or of any other suitable material, that the wheels and pulleys can be grooved at their periphery or can be made of sections of plywood or laminations to provide the groove for rubber bands or cords. By using simple directions and instructions, these parts can be assembled by anyone without the use of tools. Obviously, all shafts and apertures adopting the shafts and acting as bearings are to be of the proper dimensions and the spacers I2 and I3 would have their ends engaging the plates If! and II by means of a press fit.

In the description of the device, I have shown and portrayed a single arrangement of the component parts constituting the device and show their methods of operation. I am fully cognizant of the fact, however, that in constructing this device it is possible to make many changes in the form and configuration of the parts that will in no way affect their operativeness, and I reserve the right to make such changes as I may deem convenient or necessary without departing from the spirit of my invention or the scope of the appended claims.
