Specification of Letters Patent. Patented NOV. 12, 1918.

Application filed May 23, 1918. Serial No. 236,223.

To all whom it may concern:

Be it known that ADAM I. Knocx, deceased, late a citizen of the United'States, and a resident of St. J ohnsville, in the county of Montgomery and State of New York, invented new and useful Improvements in Machines for Applying Coatings, and that LIBBIE M. Knows, the duly constituted administratrix of the estate of ADAM I. KLocK, deceased, does hereby declare the following to bee full, clear, and exact description of the said invention of said decedent, ADAM I. KnooK, and such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to that class of machines designed primarily for'applying amalgam to mirrors although the use thereof is not limited to any particular lines.

The principal object of the invention is to provide a machine of the class specified which may be constructed and operated at comparatively little cost, yet one which will be rapid and efficient in operation. Other objects of the invention will appear as the description proceeds with reference to. the accompanying. drawings which form a part of this specification and in which:

Figure 1 is a side elevation of the improved machine with parts of the upper and lower tracks broken away and in section;

Figs. 2 and 3 are detail vertical transverse sections on the planes of the lines '22 and 3-3 of Fig. 1;

Fig. 4 is an end elevation partly in section, the two sets ;,of tracks being swung to a horizontal position Fig. 5 is a horizontal section on the plane of the line 55 ofFig. 1 but showing the tracks in a horizontal position for the sake of clearness; 9

Fig. 6 is an enlarged side elevation of the brake actuating lever and Fig. 7 is a horizontal section thereof on the plane of the line 77 of Fig. 6;

Fig. 8 is an enlarged vertical section of the amalgam tank and the car which carries the plate to be coated;

Fig. 9 is an enlarged side elevation of the amalgam tank; and,

of being held in any position by screws 6 I which are received slidably in the longitudinal slots 7 with which the bars 4 are. provided. It is the function of the rod 3 to limit the tilting movement of the upper and lower tracks .yet to be described.

Each side frame 1 is provided with a horizontal plate 8 disposed about midway between its upper and-lower ends and secured to its side bars, said plates revolubly supporting a horizontal transverse'shaft 9 upon which bearings 10 are clamped by set screws or the like 11 (see Figs. 4 and 8), said bearings being carried rigidly between the upper and lower tracks 12 and 13 and disposed midway the lengths ofsaid tracks. Both sets of tracks are thus mounted for tilting movement and are adapted to move between the positions shown in Figs. 1 and 5.

The tilting of the tracks toward the vertical is limited by the rod 3 which may be adjusted to any required extent, whereas stops 14. (see- Fig. 1) prevent the movement of the'tracks beyond a horizontal position.

The upper and lower pairs of tracks are spaced apart by blocks or the like 15 and although said tracks could well be of any preferred formation, they are preferably constructed of angle iron. Upper and lower cars 16 and 17 travel respectively on the tracks 12 and 13, said car 17 serving only as a weight for overbalancing 16, the two being connected by a cable 18 passing around pulleys 19 carried by transverse bars 20 which i connect the upper ends of the several tracks. Another cable 21is connected to the lower end of the car 16 and passes around the pulleys 22 mounted on transverse bars 23 by which the lower ends of the tracks are connected, said cable being wound at its other end on a drum 24 which is mounted rotatably on one end of the shaft 9. It will thus be seen that when cable 21 is wound on said drum, the car 16' will be moved toward the front of the tracks 12, whereas the car 17 will travel in the reverse direction to return 16 to its initial position, when the driving means of the drum are released.

Any suitable arrangement of parts could well be employed for rotating drum 24 but one end thereof is preferably provided with a spur gear 25 meshing with a similar gear 26 on a short transverse shaft 27 which is supported rotatably by one of the plates 8, a two-part clutch 28 being provided for driving said shaft, one part of said clutch having a suitable operating handle 29 (see Fig. 3 for details). By the provision of the clutch 28, the shaft 29 may be rotated to so turn the gears 26 and 25 as to rotate the drum 24 to wind cable 21 thereon, thus moving the car 16. toward the front end of its tracks 12. When, however, the clutch is released, the weight of the car 17 comes into play to return car 16 to its previous position, the tracks being then inclined as shown in Fig. 1. This return movement of the car 16 takes place after the plate to be coated has been placed thereon, and in order to prevent the parts from moving too rapidly, a brake 30 is provided to control the drum 24.

Brake 30 may be of any suitable construc tion but is preferably in the form of a short vertically disposed lever having a lateral offset 31 by means of which it is fulcrumed on a longitudinal rod 32 which is supported by one of the side frames 1, immediately above the plate 8 (see Figs. 1 and 2). Brake 30 is applied by a coiled spring 33 which exerts its tension outwardly on the upper end thereof, and for the purpose of releasing said brake, a link 34 extends outwardly therefrom and is pivoted to a horizontally swinging hand lever 35 which is fulcrumed to a vertical bracket or the like 36 secured at one end to one of the plates 8 and at its other end to an angle iron bar 37 above said plate, each. frame 1 being provided with one of said bars 37 for a purpose to be described.

For locking the lever 35 in position to release the brake 30, a dog 38 is pivoted to one of the side bars of the frame 1 upon which said lever is mounted, said dog pass ing through openings in the lever and being normally moved by a spring 38 into engagement with a shoulder 38 thereon, the lever being preferably of the hollow construction shown in Figs. 6 and 7, so that a rod 39 may slide therein for the purpose of releasing dog 38 when it is required that sprmg Lasagna 33 shall apply the brake 30, It is to be understood, however, that the force with at one end. Turning of the crank thus swings the tracks to and between the required inclined positions and a horizontal position. The segments 40 are preferably formed with openings 44 through which locking'bolts 45 may project to hold the tracks in adjusted position, said bolts being slidably mounted in any preferred manner and being preferably connected at their inner ends with a vertical rod 46 by means of inclined links 47 (see Figs. 1 and 4). The lower end of rod 46 is pivoted to a crank arm 48 on a transverse rock shaft 49 having a pedal 50 for operating it, a suitable spring 51 being employed for normally so positioning said rock shaft as to project both bolts 45. When the pedal 50 is depressed, however, the bolts are retracted, whereupon rotation of crank 43 will swing the trac { S 12 and 13 as required.

A tank 52 is provided for containing the amalgam or other coating to be applied, said tank having a reservoir compartment 53 in its upper end and a working compartment 54 in its lower end, the two being in communication When valve 55 is opened as shown in Fig. 8. Openings 56 establish constant communication between the Working compartment 54 and a transversely extending spout 57 over the straight upper edge on which the coating material is delivered to the plate or glass 58 carried by the car 16, electric heaters 59 being preferably employed for heating the contents of the tank 52 .in order that they may flow freely.

A bar or other suitable spring-raised member 60 extends across the spout 57 and is rockably mounted therein, being adapted to be forced downwardly into the coating fluid to cause the same to overflow from the delivery end of the spout, this operation being facilitated by a pusher bar 61. For depress .ing bar 60, crank arms 62 are carried by a rock shaft 63 which extends through the sides of the spout 57, .the outer end of said shaft having an adjustable arm 64 operated by a longitudinal strip or track 65 carried by one edge of the car 16. Fhe pusher bar 61 is carried by arms 66 depending from a rock shaft 67 which is parallel with shaft 63, the end of the shaft 67 remote from the arm 64 being provided with an adjustable crank arm 68 for engagement with a second vIlOO track or strip 69 on the edge of car 16 remote from 65.

Track 69 also operates a third adjustable crank arm 70 (see Fig. 9) saidv arm serving to operate a lever 71 which is fulcrumed on one side of the tank 52. A link 72 rises from lever 71 and is pivoted to a lever 73 which is connected with valve 55 by means of a vertical link 74 (see Figs. 4, 8 and 9).

By the arrangement of parts just described, including the three adjustable arms 64, 68 and 70, upward movement of the car 16 under the action of the weighted car 17 will open valve 55 to supply a quantit of coating fluid to the compartment 54,- rom the spout of which it is caused to overflow by depression of the member 60 and outward feeding of the pusher bar 61 The fluid is thus forced over the edge of the spout onto the plate or glass 58 as the latter travels beneath said spout, and as the car moves upwardly, the valve 55 is gradually opened a greater amount and the bars 60 and 61 slowly moved. This operation is caused by the fact that the tracks and 69 are divergent in respect to the tracks 12 upon which the car 16 travels as will be clear from Figs. 1 and 8. By gradually opening the valve a greater amount, it is insured that suflicient coating fluid shall be supplied to the working compartment 54 to compensate for that forced over the edge of the spout 57, and the positioning of the aforesaid tracks 65 and 69 causes the bars 60 and 61 to continue moving throughout the period of time taken for the car 16 to travel thereunder.

The car 16 may be constructed'as occasion may demand but is preferably formed as shown in Figs. 1, 5 and 8. A pair of axles 75 extend between the wheels 76 which travel on the tracks 12, and a-pair of longitudinal side bars 77 are supported by said axles, said side bars adjustably supporting the tracks 65 and 69 by means of set screws or the like 78. Two longitudinal reach bars 79 are secured at their ends to the axles 75, and immediately above said reach bars, two supporting bars 80 are provided to receive thereon the plate to be coated, said bars 80 being supported from the reach bars 79 by coiled springs 81 which permit said bars 80 to move downwardly according to the thickness of the plate 58.- Upward movement of the bars 80, however, is limited by screws 82 V which pass slidably throughathe reach bars- 7 8 and are threaded into bars 80, said screws preferably passing through the springs 81. An undercut transverse bar 83 is provided at.

the rear or upper end of the car 16 to receive thereunder one end of the plate 58 as shown in Fig. 8, the lower edge of said plate being engaged by .the heads 84 of pins 85 which rise from the endsof a clamp 86 which is adjustable along the reach bars 79 and may be locked in any position by the set screw 87. The clamping means for the plate or glass 58 is thus rendered adjustable so that the latter may be of any required length. a

The tank 52 may be mounted in any preferred manner but said tank is preferably adjustable longitudinally of the machine as well as vertically The. sides of the tank in question are provided with laterally extending pins 88 (see Figs. 9 and 10), said pins being received rockably' in, slide bars 89 whose outer ends are received between vertically spaced horizontal bars 90 (see Figs. 1 and 4), said bars 90 being adjustable vertically in unison by means of a pair of vertical screws 91 mounted at their lower ends tation of these screws will thus adjust the tank 52 vertically. For shifting said tank longitudinally horizontal screws 92 shown in Fig. 1 are threaded through the outer ends of the slide bars 89.

Ears 93 extend forwardly from the side frames 1 adjacent the upper bars 90 and support the transverse rod 94 upon which a pair of longitudinally slotted links 95 are pivoted, screws 96 being passed through the slots of said links and threaded into the sides of the tank 52. Tightening of these screws, after adjusting the'tank 52 as required, will hold said tank in proper position. Furthermore, by loosening the screws in question, the tank may be inclined if occasion should so demand.

It may here be stated that a certain coaction exists between the adjustable stop means 356 for the tracks 12 and 13, and the adjustability of the tank 52, in that when applying certain coating fluids, it is necessary to incline the plate to be coated a greater amount in order that the fluid may properly run as it is applied. When such adjustment is made, it is also necessary to adjust the tank 'by the means described.

'In operation, the two sets of tracks 12 and 13 are swung to a h'brizontal position by first depressing the pedal 50 to release the locking bolts 45 and then turning the crank 43.

The pedal is then released so that the bolts clamped onthe car 16. Thebrake30 has by this time been again applied and the tracks are then adjusted to the inclined i'position permitted by the rod 3, said tracks being then locked by thebol-ts 45.]"BIfik6 30 is new again released and since car 17 is of greater weight than 16, the former will move downwardly to pull the latter upwardly beneath the tank 52. As this takes place, the two tracks 65 and 69 so operate the arms ca, 68 and 70 as toopen the valve 55 and cause the bars 60 and 61 to start the flow of coating fluid from the spout 57 onto the plate 58. As car 16 is thus traveling upwardly, the inclination of the tracks 65 and 69, in respect to the tracks 12, causes the valve 55 to be gradually opened a greater amount-while the bar 60 is caused to continue in its downward movement. Similarly the pusher bar 61 continues to move outwardly to force the coating fluid over the edge of the spout and onto the plate 58. W hen the latter has been completely coated by passage of car 16 under tank 52, the tracks 12 and 13 are again moved to a horizontal position and the coated plate is removed, whereupon the machine is in condition for furtheroperation.

From the foregoing, taken in connection with the accompanying drawings, it will be obvious that although the invention is of comparatively simple and inexpensive construction, it will be highly eflicient and durable. Since probably the best results are obtained by the specific construction shown and described, this construction constitutes the preferred form of the improved machine. It is to be understood, however, that within. the scope of the invention as claimed, numerous changes may be made without sacrificing the principal advantages.
