(c1. aso-33.4) 1 The present invention relates to balers and an object thereof is to generally improve the con struction and operation of devices of this class. Further objects are to provide an improved feeder head vconstruction‘for a baler; such mechanism actuated directly from the main crank and safety means for preventing damage in the event that the feeder head is inadvertently blocked. A par ticular object of theinvention is to provide im- proved chassis‘construction in‘ a baler to facilitate transportationand including an improved tongue orv draw bar forattaching the baler te a propelling vehicle and adapted to support the baler for op eration. Further objects and advantages will be come apparent from the following description and 15 accompanying drawings in- which: ` Figure 1 is a plan View with parts broken away of a'baler embodying the invention. _ - 2 bers 8, 9, I2 and I3 defining a box-like framework constituting the extension of bale chamber B on -which mechanism M is mounted. A plate I5 ex tends substantially vertically between members 8 and I2 (Fig. 2) and a plate IB also extends sub stantially vertically between members 9 and I3, uprights I5a. and Ilia. being spaced from plates I5 and Ilìïand extended between members I2 and 8, and I3 and 9, respectively-` ‘ s Plates I5rand I6 as will be‘apparent from Fig. 1 constitute supporting means for themain or crank shaft I1 and for a gear case generally desig nated as I8. Crank shaft I1 has a journal portion I9, with which is engaged a pitman 2U in the present instance ñxed with a plunger head gen erally designated as 2|, Fig. `2. Plunger head 2| comprises a plate 22 fastened transversely of pit man 29 inv any `suitable manner as by welding, and it may be braced as by brackets or the like with parts broken away to show interior features. 20 such as 23, interposed between the pitman 20 and the plate 22. Plate 22 has ñxed therewith as by Figz. 3 isa detail of certain mechanism shown in bolts 2li-_24 slide blocks or guides 25 and 26 which contact the side portions or plates 21 and Y28 of Similar reference characters have been applied sbalefchamber4 B and guide the plunger for re-l to the same parts throughout the speciñcation 25 ciprocating movement. Any suitable type of slide and drawings. ` . - s I ` bearing may be used at this point, although in the As `seen in Fig. 2, the machine comprises` gen present instance hard wood impregnated with oil erally a baling chamber B mounted on an axle A has proved satisfactory. A third slide block 29 and supported on wheels or other suitable ground is fixed across the lower edge of plate 22 and slides engaging elements W, « the> chamber extending beyond the axle to form the main body portion 30 on plate 1 constituting the major portion of above mentioned channel member 6, being the bottom ofthe machine and a support for the actuating of the baling chamber. Block 29 may be held in mechanism generally designated as `M. A` draw place on plate 22by bolts such as 30. bar D is pivoted to the extension of bale chamber Plunger 2l accordingly performs a combination B and by which the machine may be connected reciprocating and oscillating movement which is to a propelling vehicleand readily trailed there satisfactory for baling purposes and the construc from for transportation. An engine E of any tion avoids the complication of the hinge or wrist suitable or well-known type may be mounted in pin commonly provided between pitman 20 and the region of draw bar D and connected for head 2|. ` actuating mechanism M.
