VELOCIPEDE.

SPECIFICATION formingpart of Letters Patent No. 427,076, dated May 6, 1890.

Application filed December 6, 1889. Serial No. 332,800. (No model.)

To all whom it may concern:

Be it known that I, FRANZ HAMMINGER, of Regensburg,Bavariafiermany, have invented an Improved Velocipede, of which the following is a specification.

This invention relates to a velocipede so constructed that the rider may lower himself with the saddle and may thereby apply the brakes. Thus, on going down a l1ill,the rider may in case of danger brake his machine and at the same time get his feet on the ground, thus avoiding the necessity of jumping off.

The invention consists in the various features of improvement more fully pointed out in the claims. 7

In the accompanying drawings, Figure 1 is a side elevation of a bicycle provided with my improvement. Fig. 2 is a sectional side View of the mechanism that supports the saddle, showing the bar a raised. Fig. 3 is a similar view with the bard depressed.

The letter a represents the saddle of a velocipede supported upon a bar a, the lower end of which is received by a fixed tube Z). A feather upon bar a, engaging a groove in the tube, prevents the bar from turning. Within the lower part of tube 1) there is a rod 70, to which the brake-shoe p is connected by an intermediate link. Between a collar 7c of the rod in and the lower end of tube 1) there is a springf. A second spring f is between the collar is and the rod a. The rod a is provided with a series of notches dz 6, that may be engaged by a spring-bolt 0, adapted to be moved by a series of bars 15 75, connected by bellcranks, the bar t carrying a handle g. \Vhen the spring-bolt engages the lowermost notch c, Fig. 2, the saddle a is in its usual raised position. To apply half brake, the bolt 0 is brought into engagement with notch 1;, and to apply full brake it is brought into engagement with notch d. The downward motion of bar a in these cases causes a compression of spring f, and thus the rod a is free to come into contact with rod 70. This rod, descending against the action of spring f, applies the brake-shoe. WVhen the spring-bolt c is withdrawn, (the rider having dismounted or having taken his weight off the saddle,) the spring f will push rod 70 upward to take the brake shoe off, and the spring fwill in distending raise rod a.

In order to prevent the rod a from being thrown out of the tube 17, the latter is provided on top with a perforated plate I), and the rod a has a projection h within the tube that abuts against such plate when the rod is in its uppermost position.

This invention may, of course, also heapplied to tricycles and four-wheelers.

WVhat I claim is 1. The combination of a velocipede having saddle a with a supporting-bar a, a tube 1), receiving said bar, and with a push-rod 7t, projecting into tubeb and carrying brake-shoe 19, substantially as specified.

2. The combination of saddle a and supporting notched bar a with tube Z), a rod it,

projecting into said tube, a brake-shoe connected to said rod, and with a bolt adapted to engage the notched bar, substantially as specified.

The combination of saddle a and supporting notched bar a with tube 1), a rod 70, projecting into said tube and carrying collar 70, a brake-shoe connected to said rod, a bolt engaging the notched bar, and with a pair of springs within the tube above and below the collar, substantially as specified.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

FRANZ HAMMINGER.
