Application May 14, 1934, Serial No. 725,591

1 Claim.

-The'present invention relates to paint restoring or mixing devices, adapted for use in shaking cans of paints which have stood on shelves in storage or the like for a longtime, and. wherein thepigment of the paint'has settled and separated from the oils and other fluid contents of the cans into one portion of the can and has solidified to more or less extent.

An object of the present invention is to providea compact and economical machine which may be operated by hand or otherwise for supporting one ormore cans of paint and when operated will shake the cans of paint back and forth in a bodily movement to insure the shifting the ends or sides thereof and consequently a thorough mixing operation is not accomplished. With this in view the present invention provides a machine which moves the can back and forth in a desired path substantially lengthwise of the longitudinal axis of the can and moves the can through a sufiicient distance to insure the complete bodilymovement of the can and the setting up of the desired inertia of the contents of the can to insure its shifting as the can changes or reverses its direction of movement.

Another object of the invention is to provide a machine which may support cans of different sizes merely by the interchange of a small part thereof so'that themachine may be adaptable to cans of different sizes and configurations.

With the foregoing and other objects in view, the invention will be more fully described hereinafter, and ,will be more particularly pointed out in the claim appended hereto.

Figure 9 is a diagrammatic view showing the movement of the can when being operated upon.

Figure 10 is a diagram showing the movement of the contents of the can; and

Figure 11 is a transverse section of a modified form of can support, adapted to various sizes of cans.

Referring now to the drawings, and first to the form shown in Figures 1, 2, and 3, l0 designates a frame or body portion which may be of any suitable configuration and size to support the mechanism and the cans of paint, and which is shown in the present instance as having an intermediate gear case or enclosure through which is mounted a vertical shaft ll provided. with a step bearing l2 at its lower end and which extends upwardly through the casing into the upper part of the frame. The shaft H is provided near its lower end with a beveled gear l3 which meshes with a second correspondingly beveled gear 14 fixed upon a horizontal shaft l5 which is suitably mounted in the side of the frame and has on its outer end a crank handle it by means of which the shaft 15 may be turned by hand, and which may also be provided with a pulley H by means of which the shaft may be driven by a motor or the like.

Detachably fixed upon the upper end of the shaft H is a disc I8 having a hub embracing the shaft H and carrying a set screw l9 orthe like by means of which the disc is fixed in desired position upon the shaft II. The disc l8 carries an upstanding pin 29 which is mounted eccentrically on the disc [8 and to which is hinged one end of a link 2| for swinging and reciprocating the link.

The frame or body portion is provided at its corners, or otherwise suitably spaced apart with ports 22 across which are mounted guide rods 23, there being a pair of the guide rods and the same being disposed in parallel spaced apart relation to form a guide upon which a carrier 24 is mounted. The carrier 24 is provided with blocks or bars 25 across its under side at spaced points suitably apertured to engage the guide rods 23 V of the one or more screws 28 used.

for holding the carriage thereto and guide the carriage for back and forth reciprocating movement. The other end of the link 2| is pivotally connected by a screw 26 or the like to the under "side of the carrier 24, preferably by engaging up- In the present instance, as shown particularly" in Figure l, the tray 21 is provided with two compartments divided by a central partition .29 and is adapted to hold two cans of paint, the longitudinal axes of the compartments extending in the same'general direction as thatof the guide rods 23.

It will be noted from Figure 2 that the lower side portions of the holder or tray 21 may be curved inwardly to conform to the general configuration of round cans. The tray, of course, may be given other dimensions andconfigurations, and the tray may be quickly and easily interchanged upon the carrier by manipulation In the operation of this form of the invention the shaft I5 is turned, either by the crank handle |6or the pulley IT. The verticalshaft II is thus rotated and the disc I8 is turned with the shaft so as to effect the eccentricrotary movement of the pin 20. The pin 20 thus reciprocates and rocks the link 2| and as thelatter' is pivoted to the carrier 24, the carrieris moved back and forth on the guide rods 23 with sufficient rapidity, depending upon the rotation of the shaft II, to violently shake the cans of paint. As the cans of paint are carried lengthwise of their axes back and forth on the carrier, the contents of the cans are thus bodily moved back and forth and consequently as the cans are changed in the direction of their movement the contents of the cans are violently agitated and thoroughly mixed.

It will be noted that the parts are so proportioned as to the length of the link 2| and the relative positioning of the shaft and the guides 23 that the reciprocating movements of the carrier between the ends of its stroke are continuous and uninterrupted and there is no dead center position as the pivot screw 26 is connected to the under side of the carrier 24. at one side of the medial plane of the carrier. The mechanism is thus in position at all times for easy starting and less strain is'imposed upon the working parts during the change in the direction of movement of the carrier.

In the modification shown in Figures 4 and 5, the device comprises a frame 36 of suitable construction ,to support a vertical'shaft 3| provided at its lower end portion with a beveled gear wheel 32 which meshes with a second beveled gear wheel 33 disposed on a shaft 34 mounted in the frame at right angles to the shaft 3|. The shaft 34 has adjustably fixed thereto a reciprocating arm 35 which extends laterally from the shaft 7 ,34 andthe gear wheel 33 and which is pivotally connected at its outer end to one end of a link 36 which extends upwardly and inwardly and is pivoted at its upper end to an eccentric pin 31 mounted on a disc 38. The disc 38 is carried by an operating shaft 39 which may be driven by a pulley 48 or the like for turning the shaft.

It will be noted that the pin 31 on the disc 38 ;in which a shaft 53 rotates.

is mounted on a short radius relative to its shaft 39 as compared with the long radius or length of the reciprocating arm 35 on the shaft 34. The

result is that the disc with its pin 31 may be continuously rotated in one direction to actuate the 5 link 36 and thus rock the long arm 35 back and forth and impart, through the gearing 33 and 32, a rotary reciprocating motion to the vertical Detachably mounted on the upper end of the 10 shaft 3| is a hub 40 by means of a set screw 4| or the like and this hub is provided with a plurality 'of trays or holders 42 for cans of paint, the same being'disposed in substantially a circular row about the hub and with the longitudinal 15 g This modified form of the invention imparts a rotary reciprocating bodily movement to the cans of paint,the amplitude of which is regulated by the length of the arm 35 and the relative position- 30 ing of, the eccentric pin 3'| onthe disc 38.

Another modified form of my invention embodying thesame mode of. operation as heretofore described, is, namely, the shaking of the contents of the can from end to end, but adding to this move- 35 mentof the can another movement.

The case 58 has a bracket 5| having a bearing 52, Theshaft 53 has at its free end a pulley 54, for a belt drive, and a handle 55 for manual operation. Any power mechanism as a motor may be applied to the shaft in place thereof. The other end of the shaft 53, has a disc 56, with an off center pin 51, and this pin 51 engages a piston rod 58 and has pivoted connection therewith. The piston rod 58 slides upwardly and downwardly in a pivoted bracket 53, having its free ends 68 engaging in the downwardlyv extending brackets 6|, supported by the top wall of the casing 58. The piston rod 58 passes out of the casing through an opening 63 and supports a can holder 64. By rotating the shaft 53, the can holder 64 is moved upwardly and downwardlyand at the same time laterally from the position indicated in full lines in Fig. 9, and by the reference character 65, to the upward positionindicated in dotted lines and by the reference character 66, to the extreme other lateral position centric rim 16 with set-screw 11 can hold the largest sized can. As shown in dotted lines, each larger sized can then rests on the rim adapted to the smaller sized can or cans. The can holder shown in Fig. 11 takes the place of the can holder 64 shown in Fig. 8.

By this modified form the contents of the can is subjected to a simultaneously end to end shak- 1s ing and at the same time to a side to side action,

7 whereby all of the contents of the can are thoroughly intermixed.

This modified form has the special advantage that it is inexpensive to install, and may be used in smaller paint stores, and can be operated while the customer is making his purchases, and thereby the customer is assured of taking with him a thoroughly mixed can of paint, ready for immediate use.

It is obvious that various changes and modifications may be made in the details of construction and design of the above'specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claim:-

What is claimed is:-

A means for mixing the vehicle for paint with the pigment which has settled to the bottom of the can comprising a housing, upwardly extending supports secured to the housing, horizontal guide means secured to the supports in upwardly spaced relation to the housing, a vertically disposed shaft journalled in the housing and extending above the top of the housing, a carriage reciprocable 0n the guide means, said carriage including a can receiving tray, coacting means carried by the carriage and the upper portion of the shaft to reciprocate the carriage on the guide means upon rotation of the shaft, and a drive shaft operatively connected to the first named. shaft.
