TIMING MECHANISM FOR SHOE-SHINING- MACHINES.
Specification of Letters Patent.
Patented Mar. 21, 1916.
Original application filed January 24, 1911, Serial No. 604,408. Divided and this application filed August 10, 1912. Serial No. 714,410. Renewed June 18, 1915. Serial No. 34,965.
To all whom it may concern:
Be it known that 1, CHARLES F. BURK- HART, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Timing Mechanism for Shoe-Shining Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to timing mechanism for shoe polishing machines and has for an object to present matter divided out of co-pending application Serial No. 604,408, filed January 24th, 1911.
A further object of the invention is to provide in combination with a reciprocating carriage a timing mechanism operated from a shaft which in turn is operated from the carriage, such timing mechanism controlling in various timed relations a dressing applying means, a device for holding a coin in circuit, an electric switch, and a changeable device to be observed by the operator giving directions for operating the machine.
lVith these and other objects in view the invention comprises certain novel constructions, combinations and arrangement of parts as will be hereinafter more fully described and claimed.
In the drawings :-Figure 1 is a perspective view of the timing mechanism. Fig. 2 is a top plan view of the timing mechanism with some parts of the reciprocating car riage structure. Fig. 3 is a view of the timing mechanism in elevation showing a part of the movable carriage in section. Fig. 4 is a sectional view through the timing mechanism. Fig. 5 is a view of the dash pot controlling the movements of the lever actuating the timing mechanism. Fig. 6 is a sectional view of the dressing discharging means operated by the timing mechanism. Fig. 7 is a view of the electrical switch actuated by the timing mechanism, such switch being shown closed. Fig. 8 is a view of the electric switch shown in Fig. 7, shown open. Fig. 9 is a view of the mechanism actuated by the timing device for exhibiting changeable direct-ions to the operator. Fig. 10 is a perspective view of the direction exhibiting member. Fig. 11 is a view in detail of the power transmission mechanism.
Like characters of reference indicate corresponding parts throughout the several views.
The improved timing mechanism which forms the subject matter of this application is fully disclosed in co-pending application Serial No. 604,408 filed January 24th, 1911, of which this application is a division, and is disclosed in operation in conjunction with a shoe polishing machine comprising a reciprocating carriage 20 upon which are mounted side brushes 21, toe brushes 22, top toe brushes 23 and a heel or rear brush not shown in the present drawings. The various brushes operating in the structure are not material to the present invention which embraces the timing device mounted upon a shaft 24 adjacent the carriage 20. The shaft 24 is rigidly secured to a lever 25 and is actuated between the extremes of its movement by stops 26 and 27 mounted upon the carriage 20. Springs 28 are provided for holding the lever 25 at either limit of its movement, such movement being restricted and limited by means of screws 29 and 30 by manipulating which the throw of the lever may be adjusted. Mounted also upon the shaft 24 is a sleeve 31 shown particularly at Fig. 4, carrying a ratchet wheel 32 engaged by a detent 33 which is in turn carried by an arm 34 rigidly mounted upon the shaft 24. To prevent return movement of the ratchet 32 and sleeve 31 a detent 35 is provided which engages the ratchet in the usual well known manner.
Upon the sleeve 31 are mounted a plurality of collars 36, 37, 38 and 39 each of which carries a cam respectively engaging levers 40, 41, 42 and 43. The several levers are mounted upon a common pivot 44 and are respectively connected with rods 45, 46, 47 and 48 which extend upwardly within the housing. The rod 45 extends upwardly and is pivoted to a lever 49 which carries a curved plate 50 exposed in the rear of a sight opening 51 and carrying various directions to be ob served by the operator while operating the machine. In one position the display device will exhibit direction for performing a certain operation while in another position it will indicate a different operation to be performed. The device is controlled by a spring 51 and also carries a link 52 which extends downwardly to a device indicated conventionally at 53 intended to exhibit the to tal number of operations of the machine.
The rod 46 controls a shaft 54: which carries an arm 55 which in turn controls a valve 56 to regulate the discharge of dressing from a reservoir 57, in accordance with the disclosure of an application filed on even date herewith for a dressing applying mechanism.
The rod 47 extends upwardly and is connected at 58 with a lever 59 which controls an electric switch comprising the contacts 60 and 61. The switch as shown is of an ordinary well known commercial type and is manually controlled by a push button 62 carrying a rod 63 to which is connected the collar 64 also actuating the lever 59 by which means the switch may be manually operated as well as mechanically operated. The switch is connected with line Wires 65 and 66 which take energy from the source of electrical energy 67 and operates the motor 68. At Fig. 10 a conventional means for reciprocating the carriage 20 from the motor 68 is shown, which will be more fully hereinafter described.
The rod 48 extends upwardly to and rocks the rock shaft 69 which in turn operates a link 70 connected with a lever 71 carrying upon its extremity a contact 72 spaced from the contact 73 positioned and proportioned to hold a coin therebetween as at 74:, in circuit with the motor and source of electrical energy 67. It will therefore be apparent that to supply current to the motor the switch shown at Figs. 7 and 8 must be closed, as also a coin must be between the contacts 7 2 and 73. The timing mechanism through the structure shown operates to open and close the movable contact 72 in timed rela tion to the operation of the machineso that at times the contacts are in position to receive a coin from the coin chute 75 and at other times to drop the coin from such contacts and thereby break the circuit.
The entire timing mechanism is actuated from the carriage 20, as above described, by the motor 68 through any convenient mechanism, as the worm gear 76 operating a sprocket 77 and sprocket chain 78 with other sprocket chains 79 carrying a roller 80 passing through a slot 81 in a bracket 82 carried rigidly by the carriage. It 1s apparent, therefore, that as the sprocket chain 79 is moved by the motor the roller 80 will move about the orbit of such chain and vertically in the slot 81 whereby the bracket 82 and the carxiage rigidly connected therewith will be reciprocated longitudinally of the sprocket chain 79.
To prevent the lever 25 from moving too rapidly under the impulse of the springs 28 a dash pot cylinder 83 is employed having a piston 84 reciprocated therein by a piston rod 85 pivoted to the lever 25. The cylinder 83 is preferably filled with a liquid supplied through a chamber 86 controlled by a screw plug 87. The piston is preferably provided with ports 88 extending therethrough and a valve 89 held against the piston by a spring 90. The cylinder is provided along one side, preferably the lower side, with a groove or furrow 91 tapering, as shown in the drawing, so that the piston may start upon its return movement, in the direction indicated by the arrow, rapidly but, owing to the decreasing capacity of the furrow 91 will lose its motion so that it is moving but slowly when it reaches the extreme of its movement. It will be apparent that on the return movement none of the timing mechanism is actuated as the lever is free to return Without engaging the ratchet wheel 32 so that no damage will be done if the lever 25 moves rapidly in that direction. Provision for such rapid movement is made by the port 88 and the valve 89. It will be apparent therefore that as the carriage 20 reciprocates, the stops 26 and 27 alternately engage the lever 25 to move it alternately to the opposite limits of its movement. When engaged by the stop 26 the lever 25 moves rapidly and without other resistance than 0 that of the springs 28. 'When engaged by the stop 27 the lever is moved against the resistance of the liquid contained in the dash pot 83 and therefore moves slowly so as not to break the mechanism which the device operates. As the lever 25 moves in the direction indicated by the arrow in Fig. 5 the sleeve 31 is rotated and rotates therewith the several cams forming a part of said'sleeves to actuate in proper timed relation the several levers 40, 41, 42 and 43. The actuation of the levers 40 to 43 inclusive will operate in timed relation the several parts of the structure as hereinbefore described.
I claim 1. In a shoe polishing machine, a reciprocating carriage, a shaft journaled adjacent the carriage, a lever mounted to be oscillated by the carriage and to advance the shaft with a step by step movement, a plurality of cams carried by the shaft and rotating therewith, a plurality of levers pivoted upon a common pivot and engaging the cams and operating mechanism controlled by the levers.
2. In a shoe polishing machine, a shaft mounted to rotate, cams carried by the shaft, levers engaging the cams, controlling mechanism actuated by the levers, an operating lever pivoted relative to the shaft, a recipro eating carriage, stops carried by the carriage adapted to move the operating lever alternately in opposite directions, a cylinder mounted adjacent the carriage, a piston mounted to reciprocate within the cylinder,
means carried by the piston to permit its movement readily in one direction but to retard its movement in the opposite direction, and a piston rod connecting the piston with the operating lever.
3. In a shoe polishing machine, a shaft mounted to rotate, a plurality of cams carried by the shaft, a reciprocating carriage, means for transmitting motion from the reciprocating carriage to advance the shaft with a step by step movement, movable parts engaging the cams, and mechanism operated by the movable parts for operating the mechanical parts in timed relation.
4. In a shoe polishing machine, a reciprocating carriage, a shaft journaled adjacent the carriage, a lever mounted to be oscillated by the carriage and to advance the shaft with a step by step movement, a plurality of cams carried by the shaft and rotating therewith, and operating mechanism movably engaging the cams.
In testimony whereof I afiix my signature in presence of two Witnesses.
