IMPROVEMENT IN MOLDING-MACHINES.
Specification forming part of Letters Patent No. 165,720, dated July 20, 1875; application filed June 15, 1875.
To all whom it may concern Be it known that we, ANDREW H. FRANK and GEORGE SPIRE, both of Buffalo, in the county of Eric and State of New York, have invented a new and useful Improvement in lllolding-llachines, which improvement is fully set forth in the followi. g specification, reference being had to the accompanying drawings.
Our invention relates to that class of molding-machines which are provided with two vertical spindles turning in adjustable bearings or frames, and carrying suitable cutters at their upper ends above the bed or table of the machine Previous to our invention these machines have been constructed with two supporting side frames, between which the spindles were arranged. This construction is objectionable, for the reason that the side frames cover or hide the spindle-bearings, and 'do not permit ready access thereto, whereby the operation of adjusting the spindles is rendered more or less diflicult, while it consumes considerable time. The object of our invention is to remedy this defect; and it consists of the particular construction of a supporting-frame, as will be hereinafter fully described.
In the accompanying drawings, Figure 1 is a front elevation of our improved machine. Fig. 2 is a side elevation thereof. Fig. 3 is a horizontal section in line 00 a, Fig. 1.
Like letters of reference refer to like parts in each of the figures.
A is the bed or table of the machine; B B. the two vertical spindlesor mandrels, provided above the bed with cutters I). b,- O (J, the adjustable spindle frames, having bearings o c in which the spindles revolve; and d, the driving-pulleys, secured to the spindles. All of these parts are old and well known. E is the main part of the supportingframe, consisting of a hollow column arranged centrally under the bed A and between the spindles B B. The column E is formed at its upper end with two horizontal arms, f f, supporting the bed A, and provided near each end with vertical ways g, in which the upper end of the spindleframe 0 is adjustable. h h are two similar horizontal arms, formed with the column Eat a suitable distance below the arms f f to support the lower ends of the spindle-frames, I
which are guided in vertical ways g, formed with said arms. The foot of the coluinn E is enlarged, so as to form a firm and reliable base-support. The column A is readily cast in one piece with the arms f and h and ways g g, forming a rigid and secure supportingframe for the machine, which can be produced at comparatively small expense. The supporting-column beingarranged between the spindles, the latter are fully exposed, so that free access can be had thereto when they are required to be adjusted, or for any other pur-
