MECHANICAL s'TnA-INEE- Appncatm ined my 4,

The general object of the invention` is to" provide an improved mechanical strainer which is particularly i pted for straining,A paint'l and similarI products.

A specific object of thevinvention is to provide a mechanical strainer'including a fixed member and a movable member and wherein novel 'means is provided for moving er. A Other objects of the invention will be app'arentfrom the following description taken 1n connection with the accompanying .drawin s wherein: ig. 1 is a central sectional View through a mechanical strainer embodying the eaf tures of my invention: f Fig. 2 is a section on line 2 2, Fig..1. f Fig. 3 is a section on line 3-3, Fig. 1, Fig. 4 is a fragmentary section s owing the strainer element,

Fig. 5' is a section partly. in elevation showing the eccentric mounting," Fig. v6 is a top plan view of the supporting* member,

Fig. 7 is a longitudinal section of thev n supporting member, and

I Fig. 8 is a section on line 8`-8,Fig. 7.

Referrin to the drawing by "reference l characters, have shown a. frame embodying the features of my invention at 10. This 'frame 4preferably comprises a. rectangular member, L-shaped in cross section and comprising end portions 11 and side portions 12.l The side portions 412 have flanges 13 thereon and upright members 14 at each side thereof. These members 14 areg'oined by an upper member 15- which'in'clu es an eyelh to which a lifting device 17 may be attached. l

The members 14 arev connected by a plate 18 on which a motor 19-.is mounted.. The

' members 14 near their lower extremities are clude a bearing the members 10 I show a hollow colallgected by a cross member 20 whichhas a br ket 21 thereon. This bracket v may in- 22 for the armature shaft 23 of the motor. y

Mounted, upon the lower portions of receptacle 25. lThis 'receptacle has .inturned bottom anges 26 on which removable vscreens 27 and 28 of diiferent'mesh may be arranged.

The receptacle 25 is shorter than the frame 10 so that the anges 270m themreceptacle may slide along the ianges on the frame on vthrough the aperture vreceptacle 25 has a pin 35 thereon which en- 1923. yserial No. 106324.

supporting members to be later described.

The receptacle has nobottom but has a top v 28 which is fixed thereon and which includes a door 29. at one end Ymounted onza pintle or other hinge member 3 0.- The door has a handle member 31. This door 29 serves'to enable the screens 27 and 28 to be removed and inserted as desired. The fixed top is shown as providedwith.an aperture 33 and with la `tray 34 about this aperture.

The paint Aor other products is preferably poured intev -thetray whence it passes 33. The top of the gages a pitm'an.' This pitman 36 has a drical collar 38 which is eccentrically mounted on the armature shaft 22 as .shown in Fig. 5. I preferably make the pitman A36 of two parts 39 and 40 whichare secured together by removablefastening' members .bearing 37 `thereon which ,enga-ges a cylin- 41 as shown. When the motor is operating the shaft 22 will rotate and Ascreen together with the short travel thereof causes the paint or other particles engaging the screen to be sheared by brushing against the-screen so that not only a straining action but also a mixing action is present.

l will rotate the cylindrical collar 38 which is pinnedto the pin 42, thereby causing My strainer may be readily 'shifted about by operating the lifting member 17 so that the same strainer may be used at a number of 'stations in a facto -In'Figsl 6, 7 and 8 showthe supporting members which are preferablyinserted btween the iianges 27 on lthe receptacle, and

the flanges 13 on the frame. These supporting members, indicated` generally at 45, `comprlse a body 46 having a cavity 47 in the upper faces in which anti-friction members such as balls 48 areprovided. The` supporting members 45 may beheld in place by fastening mem rssuch as bolts 49. I now preferto use our of the supporting members though their particular arrangement and construction may be varied.

.Having thus described my'invention, -I

claim: v -Y ,l l. In a portable Amechanical str-amer, a

frame, a motor rigid with respect -to said vframe Work, a strainer slid-ably mounted on I said'frame Work and eccentric means conframe Work, a motor rigid With respect to said frame Work, ay strainer slidably mounted on said frame Work and eccentric means connecting said motor and said strainer to rapidly reciprocate said strainer.

3. Inl a mechanical strainer, a frame having a receptacle slidable therein, a motor adjacentsaid frame, said motor having an armature shaft, an eccentric on, said armature shaft, a pitman engaging said eccentric, said .pitman being secured to said receptacle 'to move the same.

4. In a mechanical strainer, a frame, a yoke carried by said fra-me, supporting meanss'engaging said'yoke, a motor on said frame,a strainer 'member movable on said frame, and means operated by said motor for reciprocating said strainer.

5. In a mechanical strainer, a frame,

-means to support said frame, a motor, on said frame, said motor having an armature shaft,

a strainer member movable on said frame, a pin on said member, a pitman engaging said pin, a bearing carried by said pitman, and means to eccentrically connect said shaft to said bearing.

6. In a mechanical strainer a hollow rectangular frame having flanges thereon, a yoke carried by said frame, a web on said yoke, a motor mounted on said Web, said motor having an armature shaft, a strainer member having removable strainer elements therein, a cover on said member, a pin mounted.on said cover, a pitmanvengaging said pin, a bearing carried by said pitman, a collar mounted on said bearing to" rotate therein, said armature shaft passing through said collar and being eccentrically arranged With respect to the axis`r thereof, said shaft .being pinned to said collar.

In testimony Whereof,-I hereunto aix my signature.
