UNITED STATES PATENT OFFICE.

CHARLES H. PALMER, OF AMESBURY, MASSACHUSETTS.

CARRIAGE-AXLE.

SPECIFICATION forming part of Letters Patent No. 519,732, dated May 15, 1894.

Application filed A t 30,1893, S rial No. 484.365- (No model.)

To whom it may concern.-

Be it known that 1, CHARLES H. PALMER, of Amesbury, in the county of Essex and State of Massachusetts, have invented a new and useful Improvement in Carriage-Axles, which will, in connection with the accompanying drawings, be hereinafter fully described, and specifically defined in the appended claim.

In said drawings Figure 1 is a side elevation of an axle end complete, constructed according to my method. Fig. 2 shows the axle collar in longitudinal section, and as in place upon the axle, the outer end of the latter being broken away. Fig. 3 is an elevation of the collar shown in Figs. 1 and 2, and taken as viewed from the left in said figures. Fig. 4 is like Fig. 2, except that there is no concentric groove in the collar for the reception of the end of the box, as in Fig. 2. Fig. 5 is an elevation of the collar shown in Fig.

i 4, taken from the left, as in Fig. 3. Fig. 6 is a sectional elevation like Fig. 2, except that the section through the collar is taken on the diagonal of the axle where the groove between the internal round and square portions of the collar does not show.

The object of my invention is to produce an axle at low cost, in duplicated form, and in readiness to be applied to the vehicle. And the invention consists in an axle made of proper length, direct from rolled bars of metal, having only the ends forged, and then turned; and then provided with collars that have been lathe finished, and which are, by suitable pressure, forced to place upon the axle.

Referring again to said drawings, A represents the axle arm, and B the axle bed; the latter being square in cross section and the arm being round.

C is the collar, which is formed with a square portion a, that bears upon part B of the axle bed; and with a portion 1), that is round both inside and out, and which bears upon part A of the axle arm. In said collar is formed a concentric chamber e, that has a diameter equal to the diagonal of part B as shown by line 0. When the collar is formed of large size, as in Figs. 1, 2 and 3, an annular recess or groove d is formed in its front face, into which a lip, formed upon the box, enters to constitute a grease and gravel guard. But when the collar is of small size, as in Figs. 4 and 5, the rear end of the box extends back over the collar and incloses the same. The axle proper will be formed from rolled bars of metal of the size of part B, and will have the ends A rounded to size; while the collars C will be formed preferably of cast metal, and the rounded part b will be turned, inside and out, while the internal square part of a that receives part B may be cut to size by a broach or punch forced into it for the purpose of giving it finished size.

Reference to Fig. 6, in connection with Figs. 2 and 4, will render it plain that groove e is of a diameter equal to the diagonal of part B of the axle and hence constitutes the dividing line between the chamber in part a and the interior of part b, so that either part a or b can be finished internally without interfering with the other.

It --will be obvious that by my invention axles can be made rapidly and cheaply, with every appearance of having a solid collar, and without the cost of reducing parts A and B from a bar the size of collar 0; or the expense of forming said collar by upsetting a bar the size of B.

I do not claim in the abstract the driving or forcing of a collar upon an axle, as heretofore it has been common to force a disk-like collar upon part A, against the shoulder formed upon part B, by rounding part A.

What I do claim is In a carriage axle formed with round arm A and square bed B, a collar 0 formed with portion a that fits upon part B of the axle, and part b fitting upon portion Aof the axle, and having an interior chamber 6 arranged between said portions (1 and b, substantially as specified.
