nnvron non APPLYiNGoUTLET FITTINGS TO FILTER LEAVES.

Application filed May 18, ms. Serial No. 30,979.

This invention relates to a blamping device provide simple means for applying this fitting to the assembled leaf and *f'orclampmg its jaw portions in gripping relation to the leaves.

\ which The present invention contemplates the use of a pair of simultaneously moving clamping jaws adapted to cooperate in forcing the jaws of the outlet fitting against the opposite sides of the filter leaf and to permanently grip the leaf.

' The invention is illustrated by way of ex ample in the Fig. 1 is a View in perspective showing the operation of the present nvention.

Fig. 2 is an enlarged view in transverse section through the device with which the" present invention is concerned showing the v manner in which the outlet fittmgs are acted upon.

. Fig. 3 is a view in section showing the outlet fitting in the condition it is applied and further disclosing in dotted lines the position of the jaw members therefor when the fitting has been closed onto the leaf.

Fig. 4 is a fragmentary view in elevation showing; the portion of the assembled filter leaf with the outlet fitting applied thereto.

Referring more particularly to the drawings, 10 ndicates a suitable rigid support upon which are mounted bearing blocks 11 and 12; The upper block 11 is fastened to the support by suitable eye bolts 13- and 14,

.while the lower block 12 is rigidly-secured in position relative to the support by clamping bolts 15.

Thelower block 12 carries a pair of

pivoted jaws

17 and 13. These jaws are mounted on a pivot pin 19 carried by-the block 12 which permits the jaws to swing toward and accompanying drawlngs inismount'ed on-one about its rotation, and thus to provide means away from Teach other while being vertically suspended.

As shown inFig. 2 of the drawings, it will 1 .be seen that the adjacent faces of the jaws are suitably recessed to accommodate the outlet fitting 20. This fitting, as more clearly shown in Fig. 3, comprises a cylindrical portion which is internally threaded toreceive an outlet pipe and a pair of jaws 21 and '22, the elevation of which members is more clearly shown in Fig. 4.

' The fitting before'being applied to. the leaf has its

jaws

21 and 22 spread apart, as shown by solid lines in Fig. 3, and when it has been applied the jawsare forced together as indi cated by dotted lines in j the. same figure. The

jaws

17 and 18 are provided with pressure levers23 and 24; respectively, by which the jaws may be swung and pressure exerted. The free end of these levers are forked to receive the trunnions 25 of nuts 26 and by which nuts the levers are moved. The

nuts 26 are mounted upon the opposite ends of a screw 27 and are threaded oppositely so that rotation of the screw in a single direction. will cause simultaneous movement of the two nuts in oppositedirections. The screw is rotatably mounted within the upper bearing-member 11 and is fitted with collars 28 disposed upon opposite sides of the bearing to prevent longitudinal movement of the screw when it is rotated. A hand wheel 29 or other suitable means end of the screw to bring for applying power to the nuts, which in turn will be transferred through the

levers

23 and 24 .to the

jaws

17 and 18 for the purpose previously explained.

In operation of the present invention,-

Qan outlet fitting of the general shape shown in Figs. 3 and 4 is disposed over the marginal edgeof'an assembled filter leaf, after which the edge of the filter leaf and the out let fitting are positioned between the

jaws

17 and 18 with the fitting registering with a suitably shaped recess in the working faces of the jaws. after which the hand wheel;29 may be rotated to turn the screw 27 in a suitable direction to cause the nuts 26 to move outwardly in the direction of the arb, thus simultaneously rows 'a and swinging the

lever arms

23 and 24 in the directions of the arrows c and -d-. This will swing the'jaws relative to their pivot 19 and will force the

jaw portions

21 and 22 of the outlet fitting inwardl against opposite sides of the assembled filter leaf to grip the same as shown in F ig. 2 of the drawin 1 It W551 be understood that the filter leaf and the outlet fitting during this operation will be held in their proper vertical aligned position by an aligning member 31. The outlet fitting may then be permanently held in its gripping position by applying rivets 30 which pass'through the jaw ort-ions of the fittings and also through the lter leaf.

By reference to Fig. 2 of the drawing, it will be seen that the outlet fitting member is rigidly and temporarily held in an aligned position relative to the clamping structure by means of a center pin 31. This pin has a thread portion 32 at its lower end, which portion extends into the threaded boss 20 of the outlet fitting. A shoulder 33 on the pin abuts against the end face of the boss 20 and also against the lower face of the bearing block 12, which block carries the

jaws

17 and 18. A slotted opening 34 is formed in the upperend of the pin31 to receive a 1 tapered key 35 which is driven into the opening and temporaril clamps the pin in a position while it exten s throughthe block,

, and draws the' collar 33 against the under fiat face of the bearing block 12.

It will thus be evident that the outlet fitting will be held rigidly and in aligned position relative to the meeting faces of the

jaws

17 and 18. This insures that irrespective of the angle at which the

jaws

21 and 22 of the outlet fitting are disposed while spread, the

clam ing jaws

17 and 18 will force the

mem ers

21 and 22 down into parallel clamppositions on the opposite side of the leaf.

a will thus be seen that the device here disclosed, while simple in its construction and modeof operation, permits an enormous force to be easily applied to the outlet fitting, whereby it will be firmly clamped onto the filter leaf.

While I have shown the prefered form of my invention as now known to me, it is to be understood that various changes may be made in its construction without departing from the spirit of the invention as defined in the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is: a

1. A machine for clam ing an outlet fitting to a filter leaf, sai fitting having a threaded boss and spaced jaws extending coaxially from one end of the boss, said machine comprisin a frame, a pair of clamping jaws carrie by the frame and adapted to swing from a'common pivot, operative means for moving said jaws toward and latter be actuated to force the jaws of the fitting toward each other, the adjacent faces of the clamping jaws being recessed to accommodate the boss portion of said fitting, a centering pin'detachably connected to the frame and adapted to he. held suspended centrally between the jaws of the machine, said pin being adapted to be threadedly connected to thc'boss of the fitting to maintain the fitting in correct alignment relative tothe jaws of the machine. V

2. A machine for clamping an outlet fitting to a filter leaf, said fitting having a boss and a pair of spaced jaws extending coaxially from one end thereof, said machine comprising a stationary'bearing, a pair of clamping jaws pivotallyconnected to said bearing and adapted to swing about a common pivot, the adjacent faces of said clamping jaws being recessed to accommodate the boss portion of the fitting whereby the latter may be positioned between the clampin jaws with the boss within said recesses an the jaw portions of the fitting contiguous to the workin faces of the clamping jaws, a centering pin detachably connected with the bearing and adapted to be firmly con-- nected with the boss;of the fitting to firmly and a pairof spaced jaws extendin co-axi-' ally from one end thereof, said machine comprising a stationary bearing, a pair of clamping jaws pivotally connected to said bearing and adapted to swing about a common pivot,
