Application May 29, 1950, Serial No. 164,998
, 4 Claims.
This invention relates to new and useful improvements in time signals and the primary object of the present invention is to provide a time signal, carried on ones person, and used in conjunction with a parking meter to indicate a warning that the parking period has expired.
Another very important object of the present invention is to provide a time signal of the wrist or pocket type wherein a bell will be rung for a predetermined period of time to indicate to the user that he must return to the parking meter adjacent which his car is parked.
A further object of the present invention is to provide a signal device that is quickly and readily applied to well known interval timers or time mechanisms without in any way harmfully affecting" the normal structure or operation of such mechanisms.
A still further aim of the present invention is to provide a time signal that is simple and practical in construction, strong and reliable in use, small and compact in structure, neat and attractive in appearance, inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.
Figure 1 is a perspective view of the present invention; I
Figure 21s a group perspective View of the present invention showing the cover removed from the case;
Figure 3 is a vertical sectional view taken substantially on the plane of section line 3-3 of Figure 4;
Figure 4 is a vertical sectional view taken substantially on the plane of section line 4-4 of Figure 3; and,
Figure 5 is a perspectiveview of the brake member used in conjunction with the present invention and the rack bar carried thereby.
Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed a' preferred embodiment, of the present invention, the numeral It) represents a wellknown interval timer or time mechanism having the usual spring driven shaft I2, a latch member 14 that is swingable about its pivot 16, and a substantially L-shaped brake member l8 that is swingable about a pivot 20 extending through its apex.
An extension 22 projects from the apex of the brake member l8 and receives one eye terminal of a coil spring 24. The other end of the coil spring embraces a hook 26 on the latch member l4 and urges the enlarged notched end portion 28 of the shorter leg 30 for the L-shaped member l8 against a lateral finger 32 on the latch member 14, as shown in Figure 3.
The spring 24 normally urges the end portion 28 against the finger 32 with the brake member l8 in its brake releasing position, but as the latch I4 is moved out of engagement with the end portion 28, the leg portion swings past the latch member [4, due to the function of the spring 24, and the member l8 isurged to its brake applying position. The brake member I8 supports the usual pawl (not shown) that will engage one of the driven gears (not shown) of the mechanism In to arrest operation of the mechanism as the brake member is moved to its brake applying position.
The shaft l2 supports a laterally projecting actuator finger 34 that will ride against an abutment 36 on a swinging arm 38 to impart swinging movement to the arm 38 after the shaft I2 has rotated a predetermined'amount. The arm 38 supports a lug 40 that will ride against the latch member M to move the finger 32 away from the end portion 28 as the arm 38 is swung in response to finger 34 riding against the abutment 36.
The above described mechanism I0 is mounted within a case 42 having a pair of anchoring loops 44 that receive the inner ends of complemental wrist-strap sections 46 and 48. The sections 46 and 48 are adjustably connected by any suitable means, to retain the case upon a users wrist. The case 42 includes a removable cover 50 having a window opening 52 in which there is mounted a pointer 54 that will register with an indicia bearing disk 56. The disk 56 is formed with a square central opening 58 that receives the square end 60 of the shaft 12.
The end 60 projects through an opening 62 in the cover and receives a finger knob '64 whereby the shaft [2 may be rotated to wind the main spring acting on the shaft l2 and to bring a selected number on the disk56 in registry with the pointer 54. V
The present invention does not attempt to claim the above known construction but is merely a signal device to be used in conjunction therewith. The signal device includes a shaft 68 on which there is rotatably mounted a gear unit composed of a large gear 68 and a small gear 18. The large gear 68 meshes with the small gear of an escapement mechanism 12 including an oscillating arm 14 having a striker 16 mounted thereon.
A bell 18 is mounted within the case 42 and more specifically the frame work of the mechation to wind the main spring acting on the shaft i 2 until the selected number on the dial 55 registers with the pointer 54.
As the main spring unwinds and rotates the shaft l2, the dial 56 and the finger 34, the finger 34 will move the arm 38 to release the latch member [4 with the brake member [3 and the spring will urge the brake member 13 to its brake applying position.
The movement of the brake member to its brake applying position is gradual and the rack bar 82 must travel its length during which the alarm will be sounded. The length of the rack bar 82 is such as to actuate the striker and sound the bell T8 for approximately minutes giving sufficient notice to the wearer to return to the parking meter adjacent his vehicle.
It is anticipated that the arm 15 be employed as a switch electrically connected to a signal whereby rocking of the arm 16 will alternately make and break the circuit to the signal.
In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art.
A more detailed description is accordingly deemed unnecessary.
It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same i susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.
Having described the invention, what is claimed as new is:
1. In a time mechanism including a spring driven shaft, a swingable latch member, a swingable actuating member, a spring joining said members and urging the actuating member into engagement with the latch member and also urging the actuating member past the latch member as the latch member is moved away from the actuating member, and an actuator rotatable with the shaft for moving the latch member out of engagement with the actuating member; and a signal device including a sounder mechanism actuated by the actuating member as the actuating member is moved away from said latch member by said spring, said mechanism including a reciprocating striker sequentially moved back and forth during movement of the actuating member away from the latch member.
2. In a time mechanism including a spring driven shaft, a swingable latch member, a swingmembers and urging the actuating member into engagement with the latch member and also urging the actuating member past the latch member as the latch member is moved away from the actuating member, and an actuator rotatable with the shaft for moving the latch member out of engagement with the actuating member; a signal comprising a bell, a reciprocating striker for the bell, and gear means actuated by the actuating member as the actuating member is moved by said spring past said last member for reciprocating said striker.
3. In a time mechanism including a spring driven shaft, a swingable latch member, a swingable actuating member, a spring joining said members and urging the actuating member into engagement with the latch member and also urging the actuating member past the latch member as the latch member is moved away from the actuating member, and an actuator rotatable with the shaft for moving the latch member out of engagement with the actuating member, a signal comprising a bell, a reciprocating striker for the bell including a pair of spaced parallel lugs, a gear having its teeth alternately engaging said lugs to oscillate said striker, further gears operatively connected to said first-named gear, and a rack bar carried by said actuating member engaging and driving said further gears during movement of said brake member past said latch member by said spring, said rack bar being relatively long to rotate said gears sufficiently to move the striker into and out of engagement with the bell several times.
4. In a time mechanism including a spring driven shaft, a swingable latch member, a swingable actuating member, a spring joining said members and urging the members into latching engagement and also urging the actuating member past the latch member as the latter is moved away from the actuating member, an actuator rotatable with the shaft for moving the latch member out of engagement with the actuating member, a bell, a reciprocating striker for the bell, an operating mechanism connected to the striker for reciprocating the striker and means carried by the actuating member engaging and activating said operating mechanism after the latch member has been disengaged with said actuating member.
