170 tZZ whom iv' may concern:

Be it known that I, FREDERICK COOPER, a subject of the Queen of Great Britain and Ireland, and a resident of Handsworth, in the county of Staord, England, have invented certain new and useful Improvements in or Relating to Bicycles, Tricycles, Safeties, and other Velocipedes, also Applicable to Autocars and the Like, (for which I have obtained a patent in Great Britain and Ireland, No. 10,454, dated May 15, 1896,) of which the following is a specification.

My invention has for its object to provide better accommodation than has hitherto been provided for carrying the pump or in flater of a bicycle, tricycle, or other velocipede or autocar fitted with pneu-matic tires or other pneumatic fittings.

Heretofore in the case of a safety-bicycle a pump has merely been strapped to the top horizontal tubular bar and under the vibrations or movement of the machine has tended to get twisted out of osition and to interfere with the comfort of t erider, and, moreover, by rubbing and rattling against the said bar to remove the enamel or other finish. By my invention the pump is held perfectly secure, is readily fixed and removed, and all scratching of the enamel avoided.

In accordance with my invention and as applied, say, to a cycle with diamond frame I form (by preference) in the under side of the horizontal member 0r top stay of the frame (by which the intiater is usually carried) a longitudinal groove or recess of a length and diameter corresponding to the length and diameter of the inater. Into this groove 0r recess the inflater ts and with a strap, clip, or other suitable device passed around the tube is held securely in such groove and in line with the tube and cannot get twisted out of position, and by so lying inside the groove is to a certain extent hidden from View.

A modication of my invention consists in making the aforesaid horizontal top stay of the frame with its under side cut away to an extent which will allow the inater to be put bodily into the tube and in such way be completely obscured from View.

In order that my said invention may be more readily understood and carried into practical eifect, I have hereunto annexed a sheet of drawings and will now proceed to describe the same with the letters of reference marked thereon.

Figure 1 is a general perspective view of the top part of a gentlemans safety-bicycle with my improvements applied thereto and showing a pump or infiater fixed in position. Fig. 2 is a transverse section,' on a larger scale, on line a b. Figs. 3, 4, and 5 are transverse sections of modifications. Fig. 6 shows detail showing the reinforcement. Figs. 7 and 8 show the length of tubing in which the recess 0r opening is formed with the pump removed. Figs. 9 and l0 illustrate modifications,

In accordance with my invention I employ a tube A, in which I form by pressing, rolling, stamping, or by other suitable operation an indent, recess, or housing B slightly greater in length than the pump or intlater C to be tted therein and of a depth which permits the said infiater to be entirely embedded. The indent is such as tofleave the ends A of the tube in their original form and suited for connection to the sockets or caps of the cycle-frame, and thus I make the tube in a form which lends itself to the alteration of existing machines and does not entail any new appliances or tools for its application to new machines. The indent is (by preference) arranged to come beneath the tube when the latteris fixed, so that when the pump is placed therein it (the pump) to all intents and purposes is hidden from view and entirely protected from rain, rizo.

To retain the pump in its housing, I may employ any suitableeform of fastening, such as a ring of india-rubber D and a hooked metal part E or an elastic or other sleeve placed on the tube before fixing; but I prefer to hold the pump in position by spring-clips F, encircling the tube and formed with rolled or curved extremities or fitted with small rollersY G, which separate when the pump is being pushed into the indent, but come toward each other again as soon as the pump is fully home and by their elasticity hold the pump securely in its housing. These clips F may be Xed on the inside of the indent, if desired, and may be of channel form. To

IOO

locate and ix the spring-clip, corresponding indents may be made in the tube and clip at H or the clip may be otherwise iixed.

The extremities of the housing may be graduated; but I prefer to make them rectangular, as shown in Figs. 9 and 10, which increases the length of the tubular ends A and enables me to more effectually retain the pump in the recess and to employa stud I on one end and a spring cap or socket J on the other end, as shown in Fig. l0, between which the pump can be readily carried by the end thrust of the spring-cap. The stud I carries a rubber ring and ts into a central hole K in the pump end, and the nose of the pumppiston tits into the spring-socket J, lined with cork. In lieu of the stud I a socket similar to .I may be substituted and fitting over the pump end. This same method ot mounting the pump may be applied to the ordinary pumps by arms or abutments fixed to the exterior of the tube.

Instead of fixing the pump externally, as aforesaid, I may form an opening L inthe tube sufliciently large to admit of the pump being placed bodily in the tube, as shown in Figs. 5 and 9, Fig. 5 being a transverse section of Fig. 9 on a larger scale, with a sleeve or shell L to slip over the opening and complete the tube-section.

In all the modifications the tube may be formed with small longitudinal flutes or indentations M either upon the indented part of the tube, as shown in Fig. 2, or upon the plain or upper part of the tube, as shown in Fig. 4; but their presence is not absolutely necessary and is only desirable in tubes of very thin section. Y

The indent or housing may be lined with cork, felt, or other material for protecting the tube from disfigurement by the pump and for cushioning any rattling or vibrations, if any, between tube and pump.

As a further adaptation of my invention I may employ a double form of tube or two separate tubes arranged side by side. Similarly I may form the housing or recess as a special fitting to existing machines and in the form of a trough-like holder applied to the exterior of the tube A.

The improved tubing may be in any other part of a velocipede and in such connection be 'adapted for ladies cycles, autocars, or other vehicles which require to carry the pump in like manner.

To give additional strength to the tube, I may provide an inner tube A2, (see Fig. 6,) and While indenting the outer tube also indent and so tix the inner tube, or I may provide the ends of the tube only with an outer sleeve (shown in dotted lines) and cause it (the sleeve) to partly extend into theinden ted part of the tube and so become ixed by the indenting.

iVhile I prefer to form the indent in atube, it will be obvious that the recess may be formedin a solid bar or rod adapted for use as part of a cycle-frame and ot suitable size.

Having thus particularly described and ascertained the nature of my said invention, I declare that what I claim, and desire to secure by Letters Patent, is

Abicycle havingapump-seat formed laterally in one of its frame members, a projection carried at one end adapted to engage a recess in the base of the pump, a pin extending through the Wall of the member at the opposite end, said pin having a head at one end and carrying a clip at the other end for engaging the piston end, and a spring encircling the pin between said clip and the Wall of the frame member through which the pin passes, substantially as described.

In testimony whereof I have hereunto afiixed my signature in the presence of two Wit nesses.
