To all whom it nmg concern:

Be it known that we, CHARLES GEORGE JoHANNEsMnYnR and ALFRED R.v MoOAnN, citizens of the United States, and residents,

5 respectively, of Glendale, in. the county of Hamilton and State of Ohio, and Hamilton,

in thecounty of Butler andtstate of Ohio, have invented certain new and useful Improvements in Drip Pans, of whichthe following is a specification. V

Our invention relates to novel drip pans which are more particularly adaptedi'or use on metal planers' The objectsof our invention are. to pro.

vide oil drip pans adapted to travel wit the planer table to the end oi its outward strokes and adapted to be returned part way therewith; to provide means whereby the planer bed may be constructed considerably shorter than the distance as measured from an outer end of the table when extended in one direction beyond the end of planer bed to its outer end. when extended in the other direction beyond the end of the planer bed without the loss of oil in dripping from an extended end of the planer table; to provide means whereby oil which drips from the planer table is returned to the main reservoir; to provide means whereby movable drip pans are automatically extended by outward travel of theplaner table and automatically returned to their normal positions with the inward travel of the planer table; to reduce the expense in constructing a metal planer and increase the available space for use for other purposes.

Our invention consists in adrip pan, preferably channeled, adapted to slidably re ceive an extendable drip pan having a perforatio-n in the end thereof adapted vto re ceive a hook or pin fixedto an end of the planer table; further, in constructing said hook or pin in such a manner as to adapt it to returnsaid extendable drip pan to its normal position; further, in means fixed to the planer table and adapted to engage means fixed to the planer bed whereby said pin or hook is induced to disengage said planer table; and further, in the construction, combination and arrangement of parts as herein set forth and claimed. I

Fig. 2 is a transverse section of the same. taken on the line 2 -2 of Fig. 1;

Fig. 3 is an end elevation drip pan;

Fig. is a perspective view of the same;

Fig. 5 is a perspective view showing our improved ldrip pan and oil strainer partly broken away;

. Fig. 6 is a fragmental enlarged longitudr of our improved.

nal section taken on the line 66 of Fig. 4'

and in addition showingthe planer table in engagement with the drippan Fig. 7 is a transverse section taken on the line 77 of Fig. 4:;

. Fig. 8 is a perspective View showing our oil strainer in enlarged form; and y Fig. 9 is a side elevation showing our drip pan engaging pin or hook in enlarged form.

In the preferred construction of our invention 1 is a planer bed, 2 is a planer table, 3 is a rack fixed to the planer table and actuated by the usualtrain of gears 4, 4t, 5 and 6 actuated by any suitable means. Planer table 2 has the usual longitudinal VS 7 adaptedto travel in the usual V track 8 in the planer bed, and the planer table is secured against upward movement by suitable mechanical means asat 9. The planer bed has reservoir 10 formed therein containing lubricating oil 11 in which the lower poi-- tion of gears 4, 4, 5 and 6 rotate. Reciprocating motion is imparted to planer table 2 by bull gear 4, meshing with. rack 3 fixed to the lower portion of the planer table. Sufficient lubrication is provided for the rack and gear by teeth 12 of the bull-gearv carrying oil to teeth 13 of the rack from the oil reservoir. The portion of the mechanism as described up to this point is of usual form by the bull gear to the rack and drips therefrom onto the planer bed, the top portion of which is slightly inclined toward the reservoir. The oil is induced'to return from the top ofthe planer bed to the oil reservoir by gravitation." Considerable expense is thereby entailed in constructing a planer bed having suflicientlengthto return the oil.

For the purpose of reducing the construction cost, the weight and space consumedby a planer bed as Well as other objects herein specified, we provide means whereby the oil l-roolc 22 fixed to the endlofth'e planer table is may be returned to reservoir as hereto-tore without the necessity of constructing the planer bed of the usual length.

l/Ve preferably provide a drip pan 14 liked to each end 15 and 16 ofplanerbed 1 and having channeled sides 17 adapted to slidably receive drip pan 18 havingplate 19 fixed to its end 20. A hole 2-1 extends through end 20land plate 19 for. receivii'i'g hook 22 fixed to the end of the planer, table 15 by any suitable means such as being threaded thereto. Wedge member 23 is fixed-t0 the lower end 20 of drip pan 18-byscre'iv 24. At a predetermined point in the return movement of end 25 of table 2 the angular surface 26 ot'the wedge member is adapted to engage angular surface 27 of wedge mam ber 28 fixed to the upper. end 25 of bed 1 thereby elevating end 20 of the drip pan-for the purpose of c'lis'engagin'gliook 22' 'fr'om hole 21 of the drip pan to permit the table to continue its inward movement disengaged from drip pan 18. Pins 29 fixed inbo'tto'm 30 of drip pan 1 1 are. adapte'd to stop inwa-rdmovement of drip pan 18 produced by momentum after hook 22iis' released from engagement withhole 21'of drip pan 18.

. O'il'strainer as shown in enlarged form in Fig 8 comprisesends 3,1 and 31"and's1ides 32 and 32 secured together in any suitable manner and; has a wire screen 83' or other Suitable material fixed to the bottom there'- of. Bolts 34 c'ombinedly received inholes in end 35 of drip pan 14' andholes 36' in cars 37 fixed to side 32 of the oil strainer secures the oil strainer in the position as shown in Fig. 1 to end 35 of drip pan 14.- for the pur pose of separating toreigninatter from the oil that drips from rack 3 onto pans 141 and 18. v V

In operation the mechanism of our inven= tion is as follows: Rota-table bull' gear 4:

meshing with rack 3 imparts reciprocating motion to planer table 2 secured to the rack.

The end 25 of the planer table in its outward travelcaus'es'hook 22 to engage hole 21 in end 20 of drip pan 18 thereby sliding, drip pan 18 outwardly to the extreme point of travel of the table whereupon bull gear 4t reverses its direction otrotation thereby cans: ing rack 3 to reverse the dire'ctionoftravel of the table. Hook 22 being in engagement I with end 20 ot drip pan 18 at hole 21 carries drip pan 18 inwardly until angular surface 26 of wedge member 23fiXed to the lower end of the table contacts angular surface 27 of wedge'member 28 fixed to the up per end of the bedthereby elei' ating end 20 of drip pan 18 and disengaging nookaanom the pan. The table continues 1 its inward movement -to a predetermined'point on the bed when the bull gear reverses its direction of rotation thereby causing the planer table to reverse its direction of travel from in- Wa-rd motion to ou-twardmotion whereupon again projected through hole 21" inzend 20 of drip pan 18 and the outer end of the table contacts the inner side of end 20 of drip pan 18 thereby pushing it outwardly. This opera tion" is repeated with each reciprocating movement of the table thereby n'iaintaining drip pan 18 in position beneath rack 3 for receiving oil which dripsfrom the rack. Drip pans 1 1' and--18areslfightl-y inclined-toward oi'lres'ervoir 10 and the oil is caused by gravitation to flow inwardly toward'the resg ervoi-r through oilstrainer' 30' free from inipnrity and foreign matter such as dirt, grit, etc. w

It is" noted that thereis a; fixed drip pan 14 on each end of bed l and also a cooperating slidatieor telescoping drip pan 18 and of the bedit carries. with it in the direction it is moving the adjacent slid-able drip. pan and'durin niatume the other s'lida'ble drip pan is standing in the'pesition as shown at either endo'f Fig. 1. Thus the oil dripping from therack during the entire operations of the a table is eiiectively caught and returned to the oil reservoir;

While we have describcd'the details of the preferredembodiment; of our invention it is to be understoodthat it is capable of other adaptations and modifications within the scepe of the claims.
