Parcel-Carrier for Bicycles (Jerry M. Certain, No. 639,708)
The patent by Jerry M. Certain of Tampa, Florida, describes improvements in a Bicycle Parcel-Carrier (Patent No. 639,708, 1899). The invention consists of a pair of symmetrically-formed basket receptacles located on opposite sides of a bicycle’s forked wheel bar (either front or rear) and a simple means of attaching and detaching them.
Inventor Background: Jerry M. Certain
Jerry M. Certain was an inventor who contributed to utility and convenience solutions for personal transportation. He was also an assignee on the earlier Portable Shampooing-Basin patent (No. 590,883). This patent addresses a common need for cyclists—carrying parcels without using the often-awkward single-side or rear rack, focusing instead on balanced, front-mounted storage. The assignment of half interest to Antonio Toffaleti suggests a partnership for commercialization.
Invention and Mechanism
The carrier uses two opposing baskets that hook directly onto the wheel fork for balanced, low-mounted storage.
- Basket Structure:
- Baskets (C, C): A pair of symmetrically-formed receptacles. They have a frame/rim made of hoop-iron stays (h), with the top substantially semi-oval and the back flat.
- Lids and Covers: Each basket has a hinged lid ($i’$). If of open-work construction, they are provided with a covering (l) to exclude sand, dust, and rain.
- Attachment and Balance (Key Innovation):
- Hooks ($d, d$): Hooks are secured onto the forked bar (B) (e.g., the front steering bar) of the bicycle.
- Apertures ($e, e$): The baskets have corresponding apertures ($e, e$) in their top and bottom stays ($h$).
- Function: The baskets are quickly attached by simply hooking the apertures ($e$) over the hooks ($d$). Locating the baskets on opposite sides of the steering bar ensures the load is balanced, improving the poise and steering of the bicycle.
- Positioning: The tops of the baskets must be located low enough to avoid coming into contact with the stationary inclined brace ($r$) when the wheel turns. The baskets may be connected in front by a band ($m$) for stabilization.
Concepts Influenced by This Invention
Certain’s parcel carrier influenced subsequent accessory and storage design by pioneering balanced, low-mounted, quick-attach storage systems for personal vehicles.
- Balanced, Low-Mounted Storage: The core concept of using a symmetrical pair of receptacles mounted low on opposite sides of a central vertical element (the wheel fork) to achieve even weight distribution is foundational to modern bicycle pannier systems, low-rider front racks, and balanced scooter cargo mounts . This design maximizes stability and minimizes interference with steering.
- Simple Hook-and-Aperture Fastening: The method of using a simple, rigid hook ($d$) and a corresponding aperture ($e$) for quick attachment and detachment influenced the design of various accessory mounting systems that require ease of removal (e.g., removable storage bins, wall-mounted tool racks).
- Load Containment and Protection: The provision of integrated lids and covers (lids $i’$ and covers $l$) for weather and dust protection influenced the design philosophy of durable, dedicated storage accessories for outdoor or utilitarian use.
